Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of network transmission, in particular to a hybrid switching control method, device and system of photoelectric cooperation. BACKGROUND

[0002] The explosive growth of AIGC (Artificial Intelligence Generated Content) poses unprecedented requirements on transmission switching bandwidth and power consumption. As the core of information processing, the scale of the intelligent computing center is also expanding, and the interconnection distance of the cluster is increasing from tens of meters to hundreds of meters or even thousands of meters. The interconnection of the cluster of the intelligent computing center urgently needs low power consumption, low latency, high bandwidth and high reliability.

[0003] The existing network architecture uses electrical switches at each layer, which cannot meet the requirements of low power consumption, low latency, high bandwidth and high reliability of the intelligent computing center. In related technologies, there are optical switches that directly process optical signals to realize data transmission. Compared with electrical switches, optical switches have the advantages of low latency, low power consumption and full optical transparency. Among them, OCS (Optical Circuit Switching) is an optical signal control switching technology based on the principle of optical crossbar switch (M input optical ports and N output optical ports can be switched arbitrarily). Its core function is to quickly and flexibly route and switch signals at the optical layer, without O-E-O (Optical-Electrical-Optical) conversion. However, since OCS is port-level switching, all traffic from one port must leave the switch at the same output port, resulting in less flexibility than electrical switches.

[0004] In order to be compatible with the flexibility of port switching in data transmission and the requirements of low power consumption, low latency, high bandwidth and high reliability, related technologies exist optical and electrical hybrid networking systems, which include electrical switches and optical switches. The system uses a control scheme that separates the optical layer and the electrical layer, resulting in a complex structure and low intelligence level. SUMMARY

[0048] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein only for the purpose of describing specific embodiments of the present application, and is not intended to limit the present application.

[0050] In the related art, the cluster network of the intelligent computing center is often divided into a Spine layer (backbone layer) and a Leaf layer (access layer), wherein the Spine layer is composed of a group of Spine switches, and the Leaf switch is a next-level switch connected to the Spine switch, serving as an entry point for connecting servers and other network devices. Among them, the Spine switch is responsible for realizing the high availability and fault tolerance of the intelligent computing center network, and realizes load balancing and redundancy through a multi-path network architecture. When forwarding data, if a data packet needs to be transmitted from one Leaf switch to another Leaf switch, it will first be sent to the Spine switch connected to it, and then the Spine switch will forward the data packet to the destination Leaf switch according to the destination address, and the destination Leaf switch will forward it to the final destination server or terminal device.

[0051] In the related art, all layers of switches in the network architecture use electrical switches, which have the following disadvantages compared with optical switches: first, the power consumption is large; at the same time, the delay is high because the data packet needs to be encoded and decoded; in addition, under Moore's law, the iteration rate of electrical switch-related chips is fast, and the electrical switch is iterated every 2-3 years, and the capital expenditure is large and the cost is high under frequent iteration. In addition, the further improvement of the capacity of electrical switch chips will also face difficulties: super 51.2T switch chips may need to be combined by multiple dies (unsealed bare chips) to break through the capacity limit of a single die, and key difficulties such as "interconnection, routing, cache, scheduling" need to be overcome. In the super 51.2T era, the Serdes (Serializer / Deserializer) rate will reach 224Gbps, and will face difficulties such as high power consumption and increased attenuation of high-speed signal transmission.

[0052] The OCS switch can directly process optical signals to realize data switching without the need for optical-electric-optical conversion, and has the following advantages compared with electrical switches:

[0053] 1. All-optical transparency: independent of port rate / modulation method, during operation, without distinguishing signal rate and modulation method, it can support the integration of multi-generation different rate systems, expand without changing the networking architecture, and can greatly reduce the construction period and cost;

[0054] 2. Low power consumption: without optical-electric-optical conversion process, the device has low power consumption, especially in high-speed scenarios, the energy-saving advantage is more obvious;

[0055] 3. Low latency: without cache, the device latency is only the transmission latency of light in the device, which is greatly reduced compared with electrical switches.

[0056] However, since it is port-level switching, all traffic from one port must leave the switch at the same output port, and the flexibility of the OCS switch is poorer than that of the electrical switch.

[0057] In the related art, a network architecture for an optical-electric hybrid networking is as shown in FIG. 1, under a unified orchestration system, an optical switch and an electric switch are controlled by respective controllers, that is, the optical switch is controlled by an optical layer controller, and the electric switch is controlled by an electric layer controller, the optical signals carrying service information are transmitted between the electric switch and the optical switch, there is no management information interaction, and the optical layer and the electric layer are not aware of each other and work independently. Since the control scheme of the optical layer and the electric layer is separated, the architecture is relatively complex and the intelligent level is low. Figure 1

[0058] Based on this, in various embodiments of the present application, the management of the electric layer and the optical layer in the optical-electric hybrid networking system is planned, that is, a unified controller is used to manage the electric switch and the optical switch, thereby simplifying the networking architecture and improving the intelligent level of the optical-electric hybrid networking system.

[0059] The embodiment of the present application provides a kind of optical-electric collaborative hybrid exchange control method, it is applied to the electric switch in optical-electric hybrid networking system, as shown in FIG. 2, the method comprises: Figure 2

[0060] Step 201, the electric switch sends optical signal to the optical switch in the optical-electric hybrid networking system;Wherein, the optical signal carries service information and management information for controlling the optical switch.

[0061] Here, the optical signal between the electric switch and the optical switch can not only carry service information, but also carry management information for controlling the optical switch issued by the upper controller. Wherein, the service information corresponds to traffic data, and the management information for controlling the optical switch includes but is not limited to at least one of the following: connection establishment / removal instruction, topology reconstruction instruction, fault recovery instruction, resource query and reservation instruction, protocol adaptation instruction. Wherein, the connection establishment / removal instruction is used to establish or remove the end-to-end optical path of the specified wavelength and port;The topology reconstruction instruction is used to dynamically adjust the switch matrix of the optical cross-connect, to realize the software-defined reconstruction of the network physical topology, so as to control the OCS layer to realize millimeter-level fault switching and meet the low-latency requirement of topology reconstruction;The fault recovery instruction is used to automatically trigger backup path calculation and reroute when link interruption is detected;The resource query and reservation instruction is used to obtain port availability and reserve bandwidth for high-priority tasks;The protocol adaptation instruction is used to map service traffic to a specific wavelength channel.

[0062] It can be understood that in the embodiment of the present application, the management information of the optical switch can be forwarded by the electric switch based on the optical signal, so that the optical switch and the electric switch can share the same controller, thereby simplifying the networking architecture of the optical-electric hybrid networking system and improving the intelligent level of the optical-electric hybrid networking system.

[0063] ​​Exemplarily, the method further comprises:

[0064] The electrical switch receives the first management information and the second management information from the controller;

[0065] The operation parameters of the electrical switch are configured or updated based on the first management information, and the optical signal is generated based on the second management information.

[0066] Here, the controller is the aforementioned controller for unified management of the electrical switch and the optical switch. Exemplarily, as shown in Figure 3 The controller can accept the management of the unified orchestration system, which can centrally manage network devices, links and topology resources, monitor network operation status in real time, provide fault early warning and emergency protection measures, ensure business continuity, and the unified orchestration system realizes unified management of the electrical switch and the optical switch through the controller. Specifically, the second management information issued by the controller can be transmitted to the optical switch by the electrical switch through the optical signal, that is, the optical signal can include service signals (corresponding to service information) and control signals (corresponding to the second management information).

[0067] Here, the electrical switch can receive the first management information and the second management information issued by the controller, wherein the first management information is management information for controlling the electrical switch. The second management information is the aforementioned management information for controlling the optical switch, which can be referred to the foregoing description and will not be repeated here.

[0068] Exemplarily, the first management information includes but is not limited to at least one of the following: flow table management instruction, topology discovery instruction, QoS policy instruction, security control instruction, device configuration instruction, and fault recovery instruction. The flow table management instruction is used to add or delete flow table entries (such as matching source IP+port and forwarding to a specified exit) and / or define group table to realize multi-path load balancing; the topology discovery instruction is used to force to issue LLDP (Link Layer Discovery Protocol) probe packets to update topology and / or poll port state changes; the QoS policy instruction is used to guarantee service quality, for example, guarantee minimum bandwidth of service, speed limit policy control, etc.; the security control instruction is used to upload abnormal traffic to the controller for detection (such as distributed denial of service attack), and to urgently empty specified flow table (such as blocking worm propagation), etc.; the device configuration instruction is used to start / inhibit forwarding function, and to forcibly close ports, etc.; the fault recovery instruction is used to preset backup path, and to establish fast detection session, etc.

[0069] It can be understood that the electrical switch can configure or update the operation parameters of the electrical switch based on the first management information, so as to realize the configuration or update of the operation parameters of the electrical switch based on the instruction issued by the controller. The electrical switch can also generate an optical signal based on the second management information, so as to realize the purpose of transmitting the second management information to the optical switch based on the optical signal.

[0070] Exemplarily, the generating the optical signal based on the second management information comprises:

[0071] Obtaining service information corresponding to the optical switch;

[0072] In the process of the electrical-optical conversion of the service information, the second management information is added based on a bumping process to generate the optical signal.

[0073] Here, the electrical switch can determine the service information corresponding to the out port of the optical switch based on the flow table item, and add the second management information based on a bumping process in the process of the electrical-optical conversion of the service information to generate the optical signal.

[0074] Exemplarily, the electrical switch can control the optical module corresponding to the out port to generate the optical signal carrying the second management information based on a bumping process. Here, the bumping process means superimposing a small-amplitude low-frequency sine or cosine modulation signal on the optical signal corresponding to the service information, for example, referring to Figure 4 The optical module can load the low-frequency bumping information by slightly adjusting the signal amplitude, frequency, phase and other parameters on the basis of the optical signal corresponding to the service information, to obtain the optical signal carrying the service information and the second management information, wherein the optical signal corresponding to the service information plays a role similar to a carrier frequency. The optical module has the ability to generate an OAM (Operation Administration and Maintenance) signal based on bumping, that is, the second management information can be indicated by the OAM signal based on bumping generated by the optical module.

[0075] Exemplarily, the first management information is used to update the network topology in which the electrical switch is located, and / or the second management information is used to update the network topology in which the optical switch is located. In this way, the controller can realize the network topology reconstruction of the electrical switch and / or the optical switch based on the issued management information, so as to improve the intelligent level of the optical-electric hybrid networking system.

[0076] Exemplarily, the embodiment of the present application also provides an optical-electric cooperative hybrid switching control method applied to an optical switch in an optical-electric hybrid networking system, as shown in Figure 5 The method comprises:

[0077] In step 501, the optical switch receives an optical signal sent by the electrical switch in the optical-electric hybrid networking system.

[0078] In step 502, the optical switch performs light splitting on the optical signal to obtain a first optical signal and a second optical signal, transmits the first optical signal to an optical switching module of the optical switch, and obtains management information for controlling the optical switch based on the second optical signal.

[0079] It can be understood that the management information of the optical switch can be forwarded by the electrical switch based on the optical signal, and the optical switch can obtain the management information (i.e., the second management information mentioned above) for controlling the optical switch based on the second optical signal obtained by light splitting after receiving the optical signal from the electrical switch, so that the optical switch and the electrical switch can share the same controller, thereby simplifying the networking architecture of the optical-electric hybrid networking system and improving the intelligent level of the optical-electric hybrid networking system.

[0080] Exemplarily, the optical switch can be an OCS switch, which has the advantages of full-optical transparency, low power consumption, and low latency, and can greatly improve the transmission performance of the optical-electric hybrid networking system.

[0081] Exemplarily, the obtaining of the management information for controlling the optical switch based on the second optical signal includes:

[0082] performing photoelectric detection on the second optical signal to obtain an electrical signal;

[0083] performing filtering processing on the electrical signal, and demodulating the electrical signal after the filtering processing to obtain the management information for controlling the optical switch.

[0084] It can be understood that the optical switch has the capability of OAM signal detection in the optical signal, and thus can receive the management information from the electrical switch based on the OAM signal, and can achieve the effect of centralized control of the electrical layer and the optical layer.

[0085] Exemplarily, the method further includes:

[0086] configuring or updating the running parameters of the optical switching module based on the management information.

[0087] Here, the optical switch can configure or update the running parameters of the optical switching module based on the management information, for example, to control the OCS based on the OAM signal.

[0088] Exemplarily, the management information includes a topology reconstruction instruction, and the configuring or updating of the running parameters of the optical switching module based on the management information includes:

[0089] Based on the topology reconfiguration instruction, a switch matrix of an optical cross-connect of the optical switch module is adjusted, and a network topology in which the optical switch module is located is updated.

[0090] It can be understood that the controller can implement network topology reconfiguration of the electrical switch and / or the optical switch based on the issued management information, thereby improving the intelligent level of the optical-electric hybrid networking system.

[0091] It can be understood that in other examples, the optical switch can also control the optical switch module based on one or more of a connection establishment / removal instruction, a fault recovery instruction, a resource query and reservation instruction, and a protocol adaptation instruction, to further improve the intelligent level of the optical-electric hybrid networking system.

[0092] Exemplarily, the embodiment of the present application also provides an electrical switch applied to an optical-electric hybrid networking system, the electrical switch being configured to: send an optical signal to an optical switch in the optical-electric hybrid networking system; wherein the optical signal carries service information and management information for controlling the optical switch.

The receiving module 601 is configured to receive first management information and second management information from a controller; the processing module 602 is configured to configure or update an operating parameter of the electrical switch based on the first management information, and generate the optical signal based on the second management information.

[0094] Exemplarily, the processing module 602 is specifically configured to:

[0095] obtain service information corresponding to the optical switch;

[0096] In the process of electro-optical conversion of the service information, the second management information is added based on a push processing to generate the optical signal.

[0097] Here, the processing module 602 can determine service information corresponding to an out port of the optical switch based on a flow table item, and in the process of electro-optical conversion of the service information, the second management information is added based on a push processing to generate the optical signal. Specifically, the processing module 602 can control an optical module corresponding to the out port to generate an optical signal carrying the second management information based on the push processing.

[0098] Exemplarily, the embodiment of the present application also provides an optical switch applied to an optical-electric hybrid networking system, the optical switch being configured to:

[0099] receive an optical signal sent by an electrical switch in the optical-electric hybrid networking system;

[0100] The light signal is split to obtain a first light signal and a second light signal, the first light signal is transmitted to the optical switching module of the optical switch, and management information for controlling the optical switch is obtained based on the second light signal.

[0101] As shown in the example, Figure 7 The optical switch includes a light splitter 701, a photodetector 702, a filter 703, and a demodulator 704. The light splitter 701 is configured to split a received light signal. The photodetector 702 is configured to perform photoelectric detection on a light signal after splitting to obtain an electrical signal. The filter 703 is configured to filter the electrical signal to obtain a filtered electrical signal. The demodulator 704 is configured to demodulate the filtered electrical signal to obtain management information for controlling the optical switch.

[0102] Here, the light splitter 701 can split the received light signal into two signals based on power ratio, where the light signal with smaller power is transmitted to the photodetector 702, which converts the light signal into an electrical signal. The filter 703 is configured to filter out high-frequency service signals in the electrical signal and extract a low-frequency OAM signal. The low-frequency OAM signal is demodulated by the demodulator 704 to obtain OAM information, i.e., management information for controlling the optical switch.

[0103] As an example, the optical switch includes a control module 705 and an optical switching module 706. The control module 705 is configured to configure or update the operating parameters of the optical switching module 706 based on the management information, i.e., to implement control of optical switching.

[0105] It can be understood that in the present application, the management information of the optical switch can be forwarded by the electrical switch based on the light signal, so that the optical switch and the electrical switch can share the same controller, thereby simplifying the networking architecture of the optoelectronic hybrid networking system and improving the intelligent level of the optoelectronic hybrid networking system.

[0106] In an application example, the optoelectronic hybrid networking system is as shown in the example, Figure 8As shown, the specific signal transmission process is as follows: for the electrical switch, the unified arrangement system issues an instruction to the controller, and the controller issues a control signal to control the electrical switch. For the optical switch, the unified arrangement system issues an instruction to the controller, and the controller first transmits the control signal of the optical switch to the electrical switch. In the electrical switch, the service signal and the control signal of the optical switch are transmitted into the optical module together, and through the tuning technology, the optical signal containing the OAM signal and the service signal based on tuning is generated in the optical module. The above optical signal is received by the optical switch. First, the incident optical signal is divided into two paths by the power splitter 701 with a power ratio of 99:1. The optical signal with small power is converted into an electrical signal after being received by the photodetector 702. After the high-frequency service signal is filtered out by the filter 703, the low-frequency OAM signal is extracted, and the OAM information is obtained by demodulating the low-frequency OAM signal through the demodulator 704. Finally, the control module 705 controls the optical switching module 706 based on the OAM information. The optical signal with large power is transmitted into the optical switching module 706 to respond to the instruction of the control module 705 and perform optical switching operation.

[0107] It can be understood that the optical switch and the electrical switch are coordinated through the OAM signal based on tuning, and the controller is shared, the networking architecture is simplified, and the controller issues an instruction to the electrical switch and / or the optical switch to realize topology reconstruction.
