Description

Technical Field

[0001] The present invention relates to the field of communication network technology, and in particular to a system and method for joint scheduling of cross-network service traffic. Background Art

[0002] A communication network is a link that physically connects isolated devices to exchange information between people, people and computers, and computers and computers, thereby achieving the purpose of resource sharing and communication. The data communication network mainly completes the routing and forwarding of data messages based on the destination IP address, and the transmission network completes operations such as time slot crossing, multiplexing / demultiplexing based on the information contained in the frame header. Due to the limitation of the number of optical fiber cores and the demand for service multiplexing, the connection of network equipment (such as routers and switches) in the data communication network is mostly carried by the transmission network.

[0003] like Figure 1 As shown in the figure, the existing data communication network and transmission network each have their own network management system, which is responsible for the management and configuration of network equipment within their jurisdiction. Since the two networks are independently operated and maintained, and information is invisible to each other, the network nodes of the data communication network have more or less "through" traffic. For some network nodes near congestion, large through traffic will cause additional processing pressure on the corresponding data network equipment, increasing the risk of communication interruption while also increasing the additional transmission delay of business traffic, and introducing multiple decompression / packetization operations, routing table queries, and data message forwarding processing delays in the relay network equipment through which the communication passes. Summary of the invention

[0004] Therefore, the present invention provides a cross-network business traffic joint scheduling system and method, which directly guides the through traffic on the transmission network according to user requirements, and no longer forwards the transit traffic on the data communication network equipment, thereby overcoming the defects of the prior art that the through traffic causes processing pressure on the corresponding data network equipment nodes and increases the additional transmission delay of the business traffic.

[0044] Example 1

[0045] An embodiment of the present invention provides a cross-network service flow joint scheduling system, such as Figure 2 As shown, it is applied to the scenario of diverting the "through" traffic of the data communication network to the transmission network. Under the unified scheduling of the collaborative scheduling module, the traffic scheduling of the data communication network and the transmission network is completed by deploying a diversion device at the boundary of the data communication network and the transmission network.

[0046] In practice, the OSI (Open System Interconnect) reference model defines a seven-layer framework for network interconnection, from bottom to top: physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and application layer.

[0047] In the embodiment of the present invention, the cross-network service traffic includes: data packet traffic of the network layer in the OSI model carried by the data communication network, and frame traffic of the data link layer in the OSI model carried by the transmission network. Among them, the data communication network supports the TCP / IP protocol stack, which is used to provide a transmission carrier for packet messages and is the main transmission carrier for standard packet messages. The transmission network supports synchronous time division multiplexing technology (Synchronos Digital Hierarchy, SDH), which is used to provide a transmission carrier for SDH frames and is the main transmission carrier for SDH frames.

[0048] In the embodiment of the present invention, Figure 3 As shown, the data communication network network management module is used to send the first preset information of the data communication network to the collaborative scheduling module, and schedule the packet traffic of the data communication network according to the first instruction issued by the collaborative scheduling module. Among them, the first preset information includes: performance, alarms, configuration, security information, network traffic, and topology information of the data communication network. This is only an example and is not limited to this. In actual applications, the corresponding first preset information is selected according to actual needs. The first instruction is not limited here, and is selected accordingly according to the actual scheduling of the packet traffic of the data communication network.

[0049] Specifically, the data communication network network management module is used to manage the data communication network. The equipment of the data communication network is managed through a preset network management protocol, and the collected first preset information is reported to the collaborative scheduling module, and the unified scheduling of the collaborative scheduling module is accepted to complete the configuration of the corresponding equipment in the data communication network. The data communication network includes: data network equipment such as routers and switches and the links connecting them. This is only an example and is not limited to this. In actual applications, the corresponding data network equipment is selected according to actual needs. Specific network management protocols include: SNMP network management protocol. This is only an example and is not limited to this. In actual applications, the corresponding network management protocol is selected according to actual needs.

[0050] In a specific embodiment, the data communication network management module manages data communication network equipment such as routers and switches through network management protocols such as SNMP, and reports the collected first preset information (network traffic, topology, etc.) to the collaborative scheduling module, accepts the unified scheduling of the collaborative scheduling module, and completes the configuration of the corresponding data network equipment.

[0051] In the embodiment of the present invention, Figure 3 As shown, the transmission network network management module is used to send the second preset information of the transmission network to the collaborative scheduling module, and schedule the frame flow of the transmission network according to the second instruction issued by the collaborative scheduling module. Among them, the second preset information includes: performance, alarms, configuration, security information, time slots, and topology information of the transmission network. This is only an example and is not limited to this. In actual applications, the corresponding second preset information is selected according to actual needs. The second instruction is not limited here, and is selected accordingly according to the actual scheduling of the frame flow of the transmission network.

[0052] Specifically, the transmission network management module is used to manage the transmission network. By managing the preset transmission equipment in the transmission network, and reporting the collected second preset information to the collaborative scheduling module, the unified scheduling of the collaborative scheduling module is accepted to complete the configuration of the corresponding transmission equipment in the transmission network. The preset transmission network includes: SDH transmission equipment and the optical fiber link connecting them. This is only an example and is not limited to this. In actual applications, the transmission equipment in the corresponding transmission network is selected according to actual needs.

[0053] In a specific embodiment, the transmission network management module manages transmission equipment such as SDH, and reports the collected second preset information (time slot, topology, etc.) to the collaborative scheduling module, accepts the unified scheduling of the collaborative scheduling module, and completes the configuration of the corresponding transmission network equipment.

[0054] In an embodiment of the present invention, a diversion device is placed between a data communication network and a transmission network. The diversion device is used to divert the packet traffic of the data communication network according to the collaborative scheduling module, and then forward the diverted frame traffic to a corresponding device in the transmission network through a first device in the transmission network. The first device is not limited here, and a transmission device in a corresponding transmission network is selected according to actual conditions. For example: SDH transmission equipment, etc.

[0055] In the embodiment of the present invention, Figure 2 As shown, the diversion device includes: an uplink interface for receiving packet traffic from network devices in the data communication network and completing traffic interaction with network devices in the data communication network. A main control unit identifies the packet traffic from the uplink interface, completes the parsing and diversion of network traffic from the data communication network, and directs the identified target traffic to the corresponding downlink interface. The diverted traffic is transmitted to the corresponding port of the transmission network device through the downlink interface. A downlink interface completes traffic interaction between the data communication network and the network devices in the transmission network. The storage unit is used to store data information of the diversion device. The number of diversion devices is not limited here and is set according to actual needs in the application.

[0056] In a specific embodiment, the diversion device diverts the traffic from the data communication network according to the configuration of the collaborative scheduling module and forwards it to different ports of the transmission network device. The information sent by the collaborative scheduling module includes: a first instruction and a second instruction. This is only an example and is not limited to this. In actual applications, the corresponding information sent is selected according to actual needs. Among them, the corresponding network device of the data communication network is connected through the uplink interface to achieve two-way interaction with the data network device. The main control unit identifies the data network traffic from the uplink interface based on the destination IP address and other information sent by the collaborative scheduling module, and directs the identified target flow to the corresponding downlink interface. The corresponding port of the transmission network device is connected through the downlink interface to achieve interaction between the data network and the transmission network traffic. The relevant information is persistently stored through the storage unit.

[0057] In an embodiment of the present invention, the collaborative scheduling module is used to issue a first instruction and a second instruction respectively according to the first preset information and the second preset information user service flow joint scheduling requirements to complete the flow scheduling of the data communication network and the transmission network. The user service flow joint scheduling requirements are input according to user requirements. Specifically, according to the user's needs and the information reported by the network management module, the cross-layer network equipment and the diversion device are configured with the help of a professional network management to complete the joint scheduling of resources.

[0058] In the embodiment of the present invention, Figure 2 As shown, the collaborative scheduling module includes: a user interface unit for inputting user requirements; a communication network interface for communication connection between the data communication network network management module, the transmission network network management module and the diversion device. Specifically, the data communication network network management module and the transmission network network management module both send the data information required by the collaborative scheduling module to the collaborative scheduling module through the northbound API interface.

[0059] The protocol parsing / encapsulation unit is used to complete the mapping and conversion between user requirements and the data communication network network management module and the transmission network network management module. The display unit graphically displays the mapping and conversion relationship between the protocols. The main control unit converts the requirements input by the user interface unit into configuration instructions for the data communication network network management module, the transmission network network management module, and the diversion device. The storage unit is used to store the scheduling strategy system data. This is just an example, not limited to this. In actual applications, the corresponding system data is stored according to actual needs.

[0060] In a specific embodiment, the user's needs are input through the user interface unit. The collaborative scheduling module completes the connection with the cross-layer network management module through the communication network interface to realize two-way data interaction. The mapping and conversion between the user needs and the network management module interaction protocol are completed through the protocol parsing / encapsulation unit. The display unit completes the function of graphically displaying the data obtained from the network management module (data communication network network management module, transmission network network management module). The main control unit decomposes the user needs into control strategies that can be executed on the diversion device and the cross-layer network based on the information reported by the network management, and encapsulates them through the protocol parsing / encapsulation unit and then sends them down. The storage unit is used to store scheduling strategy system data.

[0061] In a specific embodiment, if Figure 4As shown, the collaborative scheduling module obtains the user's service flow diversion requirements through the user interface unit. Specifically, it mainly realizes the diversion of "through" service flows 2 and 3 on router R2 and "through" service flow 3 on router R3. The collaborative scheduling module obtains a global unified view of the cross-layer network based on the information reported by the data communication network network management and the transmission network network management (transmission devices S2, S3 and S4 have direct links to network devices R2, R3 and R4 respectively).

[0062] The collaborative scheduling module sends a control instruction to the diversion device located between the router R1 and the transmission device S1, requiring the diversion device to divert the service flow from the router R1 and connect service flows 1, 2, and 3 to different ports of S1 through the downlink interface of the diversion device. The main basis for diversion is based on the destination IP address of the specific service flow.

[0063] The collaborative scheduling module guides the data network "through" traffic on the transmission network through the transmission network management module, including:

[0064] (1) Configure transmission device S1: Send service flow 1 from inlet port I1 to transmission device S2 through outlet port J1. Send service flow 2 from inlet port I2 to transmission device S3 through outlet port J2. Send service flow 3 from inlet port I3 to transmission device S4 through outlet port J3.

[0065] (2) Configure transmission device S2: Send service flow 1 from ingress port I1 (directly connected to egress port J1 of S1) to router R2 through its egress port J1.

[0066] (3) Configure transmission device S3: Send service flow 2 from ingress port I1 (directly connected to egress port J2 of S1) to router R3 through its egress port J1.

[0067] (4) Configure transmission device S4: Send service flow 3 from ingress port I1 (directly connected to egress port J3 of S1) to router R4 through its egress port J1.

[0068] After the router receives the packet message from the transmission device through its POS port, it completes the transmission of the corresponding business flow according to its destination address.

[0069] In a specific embodiment, the user's business traffic joint scheduling requirements are obtained through the user interface unit of the collaborative scheduling module. The main control unit of the collaborative scheduling module generates corresponding control instructions based on the communication network topology, network traffic and other information and combined with the business traffic joint scheduling requirements, and sends them to the diversion device and the transmission network network management module. The diversion device completes the identification of the traffic from the data network device according to the control instructions issued by the collaborative scheduling module and diverts it to the transmission device through different downstream interfaces. The transmission device completes the routing and forwarding of the traffic in the transmission network according to the configuration instructions issued by the transmission network network management, and finally transmits it back to the corresponding data network device.

[0070] The cross-network service traffic joint scheduling system provided by the embodiment of the present invention includes: a data communication network, a transmission network, a data communication network network management module, a transmission network network management module, a diversion device and a collaborative scheduling module. Through the introduction of the collaborative scheduling module and the diversion device. The diversion device, the data communication network network management module, and the transmission network network management module all complete the diversion of the target service flow and the on-demand scheduling of resources under the unified scheduling of the collaborative scheduling module, and finally realize the guidance of the data network "through" traffic at the transmission layer. While reducing the processing pressure of the data communication network node equipment and balancing the utilization of network resources, the response real-time performance and service data security of the diverted service are improved, and the additional transmission delay of the service traffic is reduced.

[0071] Example 2

[0072] An embodiment of the present invention provides a method for jointly scheduling cross-network service traffic, such as Figure 5 As shown, the following steps are included:

[0073] Step S1: the data communication network management module obtains first preset information of the data communication network, and the transmission network management module obtains second preset information of the transmission network.

[0074] Step S2: The collaborative scheduling module obtains the joint scheduling requirements of user service traffic;

[0075] Step S3: The collaborative scheduling module sends a first instruction to the data communication network network management module and the diversion device according to the first preset information and the joint scheduling requirements of the user business traffic; the collaborative scheduling module sends a second instruction to the transmission network network management module and the diversion device according to the second preset information and the joint scheduling requirements of the user business traffic.

[0076] Step S4: The packet traffic of the data communication network is diverted according to the first instruction, and passes through the diversion device and the first device in the transmission network in turn. Based on the second instruction of the transmission network network management module, the diverted frame traffic is forwarded to the corresponding device in the transmission network, thereby completing the traffic scheduling of the data communication network and the transmission network.

[0077] The method for joint scheduling of cross-network business traffic provided in this embodiment realizes the identification and diversion of the business flow to be diverted through the diversion device deployed at the boundary of the data network and the transmission network under the unified scheduling of the collaborative scheduling module. The corresponding time slot crossing strategy is configured on the equipment of the transmission network to realize the diversion of business flow at the transmission network level, thereby greatly reducing the processing pressure and response delay caused by the "through" traffic on the data communication network routing equipment. At the same time, since the business flow is mainly carried by the transmission network, the security threat during data communication network transmission is also reduced.

[0078] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention.
