In addition, OTN is sinking to the urban backbone and township aggregation nodes. Large-granular services, such as home broadband OLT, are uniformly scheduled through OTN, which has become a common method.

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Figure 1 It is a schematic diagram of the service activation provided by the present invention, such as Figure 1 As shown, the service provisioning network is as follows:

[0038] (1) OTN access layer subsystem network: Responsible for accessing the OLT to the transmission network through the OTN access layer subsystem equipment.

[0039] (2) OTN backbone aggregation subsystem network: mainly carries large-granularity services and connects to the OTN access layer subsystem through service landing equipment. The original landing equipment of the core aggregation layer connects to the BRAS.

[0040] (3) Service landing equipment: Service opening equipment on OTN equipment, which realizes the extension of services to home broadband BRAS. There is also the connection between OTN access layer subsystem equipment and OTN backbone aggregation subsystem equipment. For example, A2 and A1 are in one machine room, and B2 and B1 are in another machine room.

[0041] like Figure 1 As shown in the figure, in the existing network, the C2 network element is connected to the home broadband BRAS, and BRAS and other services are generally dispatched to the A2 device. The C1 (OLT) service is also transmitted to the aggregation layer A1 device through the OTN access layer subsystem. In the machine room, the service ports of the A1 and A2 devices are connected through the equipment client side port pigtails to achieve the transmission of C1 to BRAS services. This service activation requires the laying of pigtails between the A1 and A2 devices, so that maintenance and service scheduling require a lot of manpower and material resources, and end-to-end soft scheduling cannot be achieved.

[0042] Combine the following Figure 2-Figure 4 Describe the scheduling system, method and device of the present invention.

[0043] Figure 2 It is one of the structural diagrams of the scheduling system provided by the present invention, such as Figure 2 As shown, the scheduling system 100 includes: an OTN access layer subsystem 110 and an OTN backbone convergence subsystem 120;

[0044] The first service device A1 in the OTN access layer subsystem 110 and the second service device A2 in the OTN backbone convergence subsystem 120 are connected via an optical layer.

[0045] With the explosive growth in the demand for large-bandwidth services, such as home broadband services, the services carried by OTN are becoming more and more concentrated, and the number of users is increasing. The existing service activation and protection methods cannot meet the business requirements for fast, low-cost scheduling and security.

[0046] In the prior art, the pigtail connection is directly connected to the user interface, and the data transmission ends after reaching A1 or A2. For example, the information sent from C1 can only be transmitted to A2 at the farthest, and it is impossible to realize the soft scheduling of data such as scheduling information directly transmitted from C1 of the OTN access layer subsystem 110 to C2 in the OTN backbone convergence subsystem 120. In addition, the access ring OTN to the OTN backbone convergence subsystem requires manual fiber jump in the machine room where the two networks converge, and connect through the UNI user port. This work needs to be done for each scheduled service.

[0047] In order to realize cross-network opening and scheduling of services from the OTN backbone convergence layer to the access layer, the present invention proposes an OTN cross-network soft scheduling system, and the OTN network interface A2 is connected with the A1 optical layer (optical multiplex section (OMS) layer), that is, the line side of the OTN is connected. The present invention realizes end-to-end soft scheduling of services from C1 to C2, and because the connection is realized on the OMS layer, all wavelength services can be softly scheduled, without scheduling each service and then connecting the service port.

[0048] The scheduling system provided by the present invention can realize direct information transmission between the service equipment in the OTN access layer subsystem and the service equipment in the OTN backbone convergence subsystem by changing the existing pigtail connection between the first service equipment in the OTN access layer subsystem and the second service equipment in the OTN backbone convergence subsystem to an optical layer connection, and can realize cross-network end-to-end soft scheduling, saving OTN network scheduling resources.

[0049] Figure 3 This is the second structural diagram of the scheduling system provided by the present invention, such as Figure 3 As shown, the third service device B1 in the OTN access layer subsystem 110 and the fourth service device B2 in the OTN backbone convergence subsystem 120 are connected via an optical layer.

[0050] Optionally, in the existing network, there is 1+1 sub-wavelength protection in the OTN ring, but if the port or device of the A1 or A2 device fails, it will cause service interruption, and there is no automatic active-standby protection mechanism;

[0051] In order to solve this defect, for OLT services, the services dispatched from the OTN access layer subsystem to the OTN backbone aggregation subsystem can be changed from single-end device docking scheduling to double-end device docking scheduling, such as Figure 3 As shown, in the OTN access layer subsystem, A1 and B1 are connected to A2 and B2 of the backbone converged OTN, forming a network in which the convergence and OTN access layer subsystems form a dual-node interconnected network.

[0052] Optionally, the network architecture can be adjusted to change the OTN single-device single-port interconnection mode to a dual-device dual-uplink interconnection mode to achieve dual-node cross-network protection. Among them, OTN network interface A2 and A1 are connected by the optical layer (OMS layer), that is, the line side of OTN, and B1 and B2 can also be connected by the optical layer (OMS layer), that is, the line side of OTN, which can form a dual-homing service connection mode across the OTN access layer subsystem and the OTN backbone aggregation subsystem.

[0053] Optionally, the OTN access layer subsystem may be referred to as an OTN access network or an access ring OTN;

[0054] Optionally, the OTN backbone convergence subsystem may be referred to as an OTN backbone convergence subsystem network or a backbone convergence ring OTN;

[0055] Optionally, in the dispatching system of the present invention, services can be configured on the equipment connected to another ring in each ring, wherein the ODUK1+1SNC dual-transmission and dual-reception services in the A2 and D2 directions are configured on the C2 node of the backbone convergence ring OTN. A2 can perform the ODUK1+1SNC dual-transmission and dual-reception services in the A1 and B2 directions. B2 can perform the ODUK1+1SNC dual-transmission and dual-reception services in the B1 and A2 directions.

[0056] Optionally, in the dispatching system of the present invention, the C1 node of the access ring OTN can be configured with ODUK1+1SNC dual-transmit and dual-receive services in the directions of B1 and D1. A1 can provide ODUK1+1SNC dual-transmit and dual-receive services in the directions of A2 and B1. B1 can provide ODUK1+1SNC dual-transmit and dual-receive services in the directions of B2 and A1. End-to-end soft dispatching of services from C1 to C2 can be achieved, and because A1 and A2, B1 and B2 are connected at the OMS layer, all wavelength services can be soft dispatched without scheduling each service and then connecting the service ports.

[0057] Optionally, services of all the above wavelengths may be opened on the same sub-wavelength of the same wavelength in the two rings.

[0058] Optionally, since the switching condition of the conventional OTN's ODUK1+1SNC sub-wavelength 1+1 protection is that the line-side failure alarm of the ODU triggers the switching, a dual-transmit and dual-receive function can be set in the present invention, that is, the service of each service device can be sent to the primary and backup directions (at least two directions), and signals can be received from the primary and backup directions at the same time, and the signal of the direction with better signal quality will be received.

[0059] like Figure 3 As shown in the figure, you can connect BRAS to C2 network element and OLT to C1 network element. Take the service from C2 to C1 as an example:

[0060] Optionally, when the A2-C2 link of the OTN backbone convergence subsystem fails, such as when the main link C2 to A2 fails, the C2 device can receive the A2 direction signal loss fault information, that is, the fault alarm, and the C2 device can receive the signal from the D2 direction with good service quality through the dual-receiving service, and the service scheduling information sent by C2 can also be transmitted to the A2 device through the D2 path. After the A2 device finds the C2 direction signal loss fault information, it can also receive the signal from the D2 direction, and can also send information to C2 in the D2 direction. Thus, the active-standby switching is realized.

[0061] Optionally, when a breakpoint fault occurs in the A1-D1 link in the access ring OTN, the C1 device receives the D1 direction signal loss fault information, i.e., a fault alarm. The C1 device can receive the signal from the B1 direction with good service quality in the dual-receiving service, and the service signal sent by C1 can also be transmitted to the A1 device through the B1 path. After the A1 device finds the D1 direction signal loss fault information, it can also receive the signal from the B1 direction, and also send information to C1 in the B1 direction. Thus, the active-standby switching is realized. Therefore, this network structure can realize protection when a fault point occurs in the backbone aggregation ring and the access ring respectively.

[0062] Optionally, when the A2 device fails, C2 sends scheduling information to C1. After receiving the signal loss fault information (fault alarm) in the A2 direction, the C2 device can perform OTN ODUK1+1SNC sub-wavelength 1+1 protection switching on the service to the protection time slot in the D2 direction, pass through the D2 device and reach the B2 device. The B2 device can send the scheduling information to both the B1 and A2 directions. The OTN access layer subsystem B1 device receives the scheduling information, and the access layer A1 device can receive the alarm information of the A2 device. The C1 device determines that the scheduling information received from B1 is of good quality, so it can select the scheduling information transmitted by the B1 device, thereby realizing the protection switching of the service.

[0063] Optionally, the scheduling information sent from C1 to C2 can be sent from C1 to both A1 and B1 devices, and A1 and B1 devices can send scheduling information to A2 and B2 devices at the same time. However, the scheduling information sent from A1 to A2 is terminated due to the abnormality of A2. C2 cannot receive the signal sent from A2, but can receive the fault alarm of A2. Then the scheduling information of C1 sent from B1 is transmitted to B2. B2 can judge that the signal in the A2 direction is invalid, so it can choose to receive the scheduling information in the B1 direction, perform ODN ODUK1+1SNC sub-wavelength 1+1 protection switching, and select the scheduling information in the B1 direction, which passes through D2 device and reaches C2 device. C2 judges that the signal quality received from D2 is good, so it selects the D2 device signal, thereby realizing the protection switching of the service.

[0064] In the present invention, the downtime of the standby node B2 does not affect the main service, nor trigger various switching, and the service is normal. The interruption of the standby links C1-B1 and C2-B2 does not cause service switching and does not affect the normal service.

[0065] The present invention utilizes the OMS connection method of two networks to realize end-to-end automation of protection switching. Single-node failure protection is realized by dual-node interconnection and combined with ODUK dual-transmission and dual-hand service configuration method. At the same time, service protection capability is realized when breakpoints occur in two networks at the same time.

[0066] The present invention proposes an OTN cross-network soft scheduling and protection system. The OTN access layer subsystem can be connected to two different OTN aggregation nodes through dual routes and dual connected to the protection method of BRAS, so as to realize the soft scheduling of OLT and other services and realize dual routing and dual equipment backup protection.

[0067] The present invention makes up for the defect that the existing OTN cannot realize cross-network soft scheduling and cross-network protection, and realizes the OTN cross-network end-to-end soft scheduling and cross-network active-standby dual-node protection and cross-network multi-point fault protection capabilities from aspects such as network architecture design, service configuration method, and alarm trigger switching mechanism. It realizes convenient and fast cross-network service scheduling, and realizes dual-node active-standby protection and multi-point fault protection capabilities in cross-network protection, which greatly improves network security.

[0068] The scheduling system provided by the present invention can realize direct information transmission between the service equipment in the OTN access layer subsystem and the service equipment in the OTN backbone convergence subsystem by changing the existing pigtail connection between the first service equipment in the OTN access layer subsystem and the second service equipment in the OTN backbone convergence subsystem to an optical layer connection, and can realize cross-network end-to-end soft scheduling, saving OTN network scheduling resources.

[0069] Figure 4 is a flow chart of a scheduling method provided by an embodiment of the present invention, such as Figure 4 As shown, the method is applied to the scheduling system as described in any of the above embodiments, and comprises the following steps:

[0070] Step 400, after receiving the scheduling information sent by other service devices in the first network subsystem, the first target service device in the scheduling system sends the scheduling information to the second network subsystem;

[0071] Step 410: A second target service device in the second network subsystem receives the scheduling information and transmits the scheduling information to a third target service device of the scheduling information through at least one path;

[0072] The first network subsystem is a network subsystem in the OTN access layer subsystem and the OTN backbone convergence subsystem where the first network subsystem is located; the second network subsystem is a network subsystem in the OTN access layer subsystem and the OTN backbone convergence subsystem where the first network subsystem is not located.

[0073] Optionally, the first target service device may be A1, the first network subsystem is an OTN access layer subsystem, the second target service device is A2, and the second network subsystem is an OTN backbone convergence subsystem;

[0074] Accordingly, after receiving the scheduling information sent by the service equipment in the OTN access layer subsystem, A1 can transmit the scheduling information to A2. After receiving the scheduling information, A2 can directly transmit it to the end point of the scheduling information, which is the service equipment of the OTN backbone convergence subsystem.

[0075] For example, after A1 receives the scheduling information sent by C1 in the OTN access layer subsystem, it can transmit the scheduling information to A2. After A2 receives the scheduling information, it can directly transmit it to the end point C2 of the scheduling information.

[0076] The path for A1 to receive the scheduling information sent by C1 can be C1 to D1 to A1, or C1 to B1 to A1; the path for A2 to send the scheduling information to C2 can be A2 to C2, or A2 to B2 to D2 to C2.

[0077] Optionally, the first target service device may be A2, the first network subsystem is an OTN backbone convergence subsystem, the second target service device is A1, and the second network subsystem is an OTN access layer subsystem;

[0078] Accordingly, after receiving the scheduling information sent by the service equipment in the OTN backbone convergence subsystem, A2 can transmit the scheduling information to A1. After receiving the scheduling information, A1 can directly transmit it to the end point of the scheduling information, which is the service equipment in the OTN access layer subsystem.

[0079] Among them, the path for A2 to receive the scheduling information sent by C2 can be C2 to A2, or C2 to D2 to B2 to A2; the path for A1 to send scheduling information to C1 can be A1 to D1 to C1, or A1 to B1 to C1.

[0080] For example, after A2 receives the scheduling information sent by C2 in the OTN backbone convergence subsystem, it can transmit the scheduling information to A1. After A1 receives the scheduling information, it can directly transmit it to the end point C1 of the scheduling information.

[0081] Optionally, the first target service device may be B1, the first network subsystem is an OTN access layer subsystem, the second target service device is B2, and the second network subsystem is an OTN backbone convergence subsystem;

[0082] Accordingly, after B1 receives the scheduling information sent by the service equipment in the OTN access layer subsystem, it can transmit the scheduling information to B2. After B2 receives the scheduling information, it can directly transmit it to the end point of the scheduling information, which is the service equipment of the OTN backbone convergence subsystem.

[0083] For example, after B1 receives the scheduling information sent by C1 in the OTN access layer subsystem, it can transmit the scheduling information to B2, and after B2 receives the scheduling information, it can directly transmit it to the end point B2 of the scheduling information;

[0084] Among them, the path for B1 to receive the scheduling information sent by C1 can be C1 to B1, or C1 to D1 to A1 to B1; the path for B2 to send scheduling information to C2 can be B2 to A2 to C2, or B2 to D2 to C2.

[0085] Optionally, the first target service device may be B2, the first network subsystem is an OTN backbone convergence subsystem, the second target service device is B1, and the second network subsystem is an OTN access layer subsystem;

[0086] Accordingly, after receiving the scheduling information sent by the service equipment in the OTN backbone convergence subsystem, B2 can transmit the scheduling information to B1. After receiving the scheduling information, B1 can directly transmit it to the end point of the scheduling information, which is the service equipment in the OTN access layer subsystem.

[0087] For example, after B2 receives the scheduling information sent by C2 in the OTN backbone convergence subsystem, it can transmit the scheduling information to B1. After B1 receives the scheduling information, it can directly transmit it to the end point C1 of the scheduling information.

[0088] The path for B2 to receive the scheduling information sent by C2 can be C2 to D2 to B2, or C2 to A2; the path for B1 to send the scheduling information to C1 can be B1 to C1, or B1 to A1 to D1 to C1.

[0089] Optionally, the OTN access layer subsystem may be referred to as an OTN access network or an access ring OTN;

[0090] Optionally, the OTN backbone convergence subsystem may be referred to as an OTN backbone convergence subsystem network or a backbone convergence ring OTN;

[0091] Optionally, services can be configured on the devices interconnected with another ring in each ring, where the ODUK1+1SNC dual-transmission and dual-reception services in the A2 and D2 directions are configured on the C2 node of the backbone convergence ring OTN. A2 can provide ODUK1+1SNC dual-transmission and dual-reception services in the A1 and B2 directions. B2 can provide ODUK1+1SNC dual-transmission and dual-reception services in the B1 and A2 directions.

[0092] Optionally, the C1 node of the access ring OTN can be configured with ODUK1+1SNC dual-transmission and dual-reception services in the B1 and D1 directions. A1 can provide ODUK1+1SNC dual-transmission and dual-reception services in the A2 and B1 directions. B1 can provide ODUK1+1SNC dual-transmission and dual-reception services in the B2 and A1 directions. End-to-end soft scheduling of services from C1 to C2 can be achieved, and because A1 and A2, B1 and B2 are connected at the OMS layer, all wavelength services can be softly scheduled without scheduling each service and then connecting the service ports.

[0093] Optionally, services of all the above wavelengths may be opened on the same sub-wavelength of the same wavelength in the two rings.

[0094] Optionally, since the switching condition of the conventional OTN's ODUK1+1SNC sub-wavelength 1+1 protection is that the line-side failure alarm of the ODU triggers the switching, a dual-transmit and dual-receive function can be set in the present invention, that is, the service of each service device can be sent to the primary and backup directions (at least two directions), and signals can be received from the primary and backup directions at the same time, and the signal of the direction with better signal quality will be received.

[0095] The scheduling method provided by the present invention can realize direct information transmission between the service equipment in the OTN access layer subsystem and the service equipment in the OTN backbone convergence subsystem by changing the existing pigtail connection between the first service equipment in the OTN access layer subsystem and the second service equipment in the OTN backbone convergence subsystem to an optical layer connection, thereby realizing cross-network end-to-end soft scheduling and saving OTN network scheduling resources.

[0097] If the first target service device is a first service device and the second target service device is a second service device, the first service device receives the scheduling information from other service devices in the OTN access layer subsystem and sends the scheduling information to the second service device in the OTN backbone convergence subsystem;

A1 may receive scheduling information from other service devices in the OTN access layer subsystem and send the scheduling information to A2 in the OTN backbone convergence subsystem, and A2 may then transmit the scheduling information to other service devices in the OTN backbone convergence subsystem.

[0100] Optionally, if the first network subsystem is an OTN access layer subsystem, the first target service device may be a third service device B1, and the second target service device may be a fourth service device B2. B1 may receive the scheduling information from the OTN access layer subsystem and send the scheduling information to B2 in the OTN backbone convergence subsystem, and B2 may then transmit the scheduling information to other service devices in the OTN backbone convergence subsystem.

A1 may then transmit the scheduling information to other service devices in the OTN backbone convergence subsystem.

[0105] Optionally, if the first network subsystem is an OTN backbone convergence subsystem, the first target service device may be a fourth service device B2, and the second target service device may be a third service device B1. After B2 receives scheduling information from other service devices in the OTN backbone convergence subsystem, it sends the scheduling information to B1 in the OTN access layer subsystem, and B1 may then transmit the scheduling information to other service devices in the OTN backbone convergence subsystem.

[0106] Optionally, if there is an abnormal service device in the first network subsystem, sending the scheduling information to the second network subsystem includes:

[0107] The scheduling information is sent to the second network subsystem through a path without abnormalities.

[0108] Optionally, if there is an abnormal service device in the first network subsystem, a normal path may be determined, and the scheduling information may be sent to the second network subsystem via the normal path.

[0109] For example, if the first network subsystem is an OTN access layer subsystem, when a breakpoint fault occurs in the A1-D1 link in the access ring OTN, the C1 device receives the D1 direction signal loss fault information, that is, a fault alarm, and the C1 device can send the service signal in the B1 direction with good service quality in the dual-receiving service, and the service signal sent by C1 can also be transmitted to the A1 device through the B1 path. Similarly, the C1 device can receive the scheduling information by selecting the B1 direction with good service quality in the dual-receiving service. After the A1 device finds the D1 direction signal loss fault information, it can also receive the signal from the B1 direction, and also send information to C1 in the B1 direction. Thus, the master-slave switching is realized. Therefore, this network structure can realize protection when a fault point occurs in the backbone aggregation ring and the access ring respectively.

[0110] Optionally, for example, if the first network subsystem is an OTN backbone aggregation subsystem, when the A2 device fails and shuts down, C2 sends scheduling information to C1. After receiving the signal loss fault information (fault alarm) in the A2 direction, the C2 device can perform OTN ODUK1+1SNC sub-wavelength 1+1 protection switching for the service to the protection time slot in the D2 direction, pass through the D2 device and reach the B2 device. The B2 device can send the scheduling information to both the B1 and A2 directions. The OTN access layer subsystem B1 device receives the scheduling information, and the access layer A1 device can receive the alarm information of the A2 device. The C1 device determines that the scheduling information received from B1 is of good quality, so it can select the scheduling information transmitted by the B1 device, thereby realizing the protection switching of the service.

[0111] Optionally, if there is an abnormal service device in the second network subsystem, the second target service device in the second network subsystem receives the scheduling information, and transmits the scheduling information to a third target service device of the scheduling information through at least one path, including:

[0112] The scheduling information is received through a path without abnormalities, and the scheduling information is transmitted to a third target service device of the scheduling information through at least one path without abnormalities.

[0113] Optionally, if there are abnormal business devices in the second network subsystem, a path without abnormalities can be determined, and the scheduling information can be received through the path without abnormalities, and the scheduling information can be transmitted to the third target business device of the scheduling information through at least one path without abnormalities.

[0114] For example, taking the second network subsystem as the OTN backbone convergence subsystem, when the A2-C2 link of the OTN backbone convergence subsystem fails, such as when the main link C2 to A2 fails, the C2 device can receive the A2 direction signal loss fault information, that is, the fault alarm, and the C2 device can receive the signal from the D2 direction with good service quality in the dual-receiving service, and the service scheduling information sent by C2 can also be transmitted to the A2 device through the D2 path. After the A2 device finds the C2 direction signal loss fault information, it can also receive the signal from the D2 direction, and can also send information to C2 in the D2 direction. Thus, the active-standby switching is realized.

[0115] For example, taking the second network subsystem as the OTN access layer subsystem, when a breakpoint fault occurs in the A1-D1 link in the access ring OTN, the C1 device receives the D1 direction signal loss fault information, that is, a fault alarm. The C1 device can receive the signal from the B1 direction with good service quality in the dual-receiving service, and the service signal sent by C1 can also be transmitted to the A1 device through the B1 path. After the A1 device finds the D1 direction signal loss fault information, it can also receive the signal from the B1 direction, and also send information to C1 in the B1 direction. Thus, the master-slave switching is realized. Therefore, this network structure can realize protection when a fault point occurs in the backbone aggregation ring and the access ring respectively.

[0116] The scheduling method provided by the present invention can realize direct information transmission between the service equipment in the OTN access layer subsystem and the service equipment in the OTN backbone convergence subsystem by changing the existing pigtail connection between the first service equipment in the OTN access layer subsystem and the second service equipment in the OTN backbone convergence subsystem to an optical layer connection, thereby realizing cross-network end-to-end soft scheduling and saving OTN network scheduling resources.
