Description

Technical Field

[0001] The present invention relates to the field of communications, and more specifically, to a network switching device, a data flow processing control method, and related devices. Background Art

[0002] With the development of cloud-network integration and 5G applications, users have more urgent demands for high bandwidth, low latency, and high speed. Gateway devices (three-layer switches, routers, firewalls, etc.), as traffic convergence points, can feel this pressure more deeply. Current devices have always adopted the CPU+DPDK mode. With the rapid development of the Internet, the disadvantages are becoming increasingly prominent. The performance of small packets of single devices is poor, and there is a bottleneck in the single core of the CPU. With the increase of converged services, the performance has declined significantly.

[0003] In such a complex background environment, the P4+Tofino chip programmable switch was born. As a new generation of gateway products, it has large bandwidth and high performance (single-machine bandwidth reaches several terabytes or even tens of terabytes), and small packet line-speed message forwarding. Compared with X86 servers, the single-core performance has been improved by nearly 100 times, and the overall performance has been improved by several times. In the programming of P4 programmable chips, the limitations of the chip design itself and the small amount of memory, whether SRAM or TCAM capacity, are not comparable to X86 servers.

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0046] See also Figure 1 , is a flow chart of a data stream processing control method provided in an embodiment of the present application,

[0047] In a first aspect, the present invention provides a data stream processing control method, comprising:

[0048] External interface 101, used for connecting external devices;

[0049] The P4 programmable switching chip 102 is connected to the external interface, and is used to send and receive message data corresponding to the external device, identify the message type of the message data, process stateless messages, and send control messages to the X86 processor and send stateful messages to the NP processor;

[0050] X86 processor 103, used for receiving and processing the control message sent by P4 programmable switching chip;

[0051] The NP network processor 104 is used to receive and process the stateful message sent by the P4 programmable switching chip.

[0052] Exemplarily, this application aims at the insufficient session table entries of P4 programmable chip, solves the drawbacks of large-traffic session storage, and introduces session expansion hardware NP network processor. This device architecture is simple to implement, powerful and low in complexity. The device includes an external interface, a P4 programmable switching chip, an X86 processor and an NP network processor. The P4 programmable switching chip carries message distribution, and external data messages are received via the physical port of the device. The chip forwards control messages such as BGP to the X86 processor according to the service type, and forwards stateful services such as network load balancing LB / NAT to the NP network processor chip to search and create a new session. P4 programmable implements stateless service processing such as QOS and EIP, and high-performance forwarding does not require the assistance of NP network processor chip. P4 programmable designs simple algorithm logic such as LB middle and back-end RS selection, NAT replacement of IP / PORT, etc., combined with NP network processor chip search and new session creation, to achieve consistency in service inflow and outflow processing. The P4 programmable chip defines the NP chip interaction message header format such as session_add and session_lookup, and processes the NP chip return message for subsequent service processing. The NP network processor performs session search and creation functions on the data plane according to the predefined message header, designs an efficient ultra-large session storage architecture, and has functions such as message-triggered session timeout reset and session timeout aging. It also provides complete monitoring and management capabilities on the X86 processor side, with session custom display, session timeout management, table usage statistics, forwarding and packet loss statistics, and chip health status functions. The X86 processor runs the operating system and provides complete configuration distribution and system management functions. The business processing method completed by the above new architecture has obvious advantages: hardware cost reduction, performance improvement, the whole machine can reach 800G or higher throughput, LB / NAT business capabilities are greatly improved, low latency and no packet loss. Network functions support QOS, EIP, LB, NAT and other functions, and have strong subsequent expansion space based on P4 programmability; large-capacity flow table storage, supporting up to 20 million session table item storage; flexible management and control, and convenient upgrade.

[0053] In summary, the network switching device proposed in this application includes an external interface, a P4 programmable switching chip, an X86 processor and an NP network processor. It is connected to an external device through an external interface. The P4 programmable switching chip can identify the type of data message of the external device and send the corresponding message to the corresponding processor for processing. It can solve the problem of insufficient session table entries of the P4 programmable chip, reduce hardware costs, have low latency and no packet loss, have strong expandability, flexible management and control, and convenient upgrades.

[0054] In some examples, the capacity of the external interface is 100G to 800G.

[0055] For example, in order to enable the switching device to perform large-capacity and fast network processing, the capacity of the external interface needs to be increased accordingly. The capacity of the external interface can be increased by 100G to 800G, and the throughput of the entire machine can reach 800G or higher. The LB / NAT service capabilities are greatly improved, with low latency and no packet loss.

[0056] In a second aspect, the present application proposes a data flow processing control method, which is used in the network switching device proposed in the first aspect, and is characterized by comprising:

[0057] S210, controlling the P4 programmable chip to receive a data message sent by an external device connected to the external interface;

[0058] Exemplarily, the entire P4 control process includes packet header parsing, programmable in-pipeline, configurable cache management TM, and programmable out-pipeline processing. The corresponding programming framework includes custom message headers, match-action table entry definitions, and the concatenation of full-pipeline control flows. It can be seen that the core feature of the P4 model is still high-speed switching based on network packet processing. It can realize the processing of Packet communication-related events, flexible matching, flexible editing, and small-capacity high-speed storage search. The programmable model of P4 is relative to the traditional fixed-pipeline switching chip. Its architecture is the PISA (Protocol Independent Switch Arch) full-pipeline programmable architecture. The P4 programmable chip receives data packets sent by external devices connected to the external interface. The P4 programmable capability has strong subsequent expansion space, which is convenient for later business expansion.

[0059] S220, instructing the P4 programmable chip to identify the message type of the data message;

[0060] Exemplarily, the message type of the received data message is quickly identified by the P4 programmable chip. An intelligent algorithm may be installed, or a message header comparison table may be predefined in the P4 programmable chip to identify the message type by looking up the table, wherein the data message type may include a control message, a stateless message, and a stateful message.

[0061] S230, managing the above-mentioned P4 programmable chip to send the above-mentioned data message to the corresponding target processor for data processing based on the above-mentioned message type, wherein the above-mentioned target processor includes a P4 programmable chip, an X86 processor and an NP network processor, and the above-mentioned data message includes a control message, a stateless message and a stateful message.

[0062] Exemplarily, after the P4 programmable chip identifies the message type of the data message, different types of messages are assigned to different processors for processing, where the processors include the P4 programmable chip, the X86 processor and the NP network processor. By utilizing the advantages of each processor in message processing, fast processing of message data can be achieved.

[0063] In summary, the data flow processing control method proposed in this application, the P4 programmable switching chip can identify the type of data message of the external device and send the corresponding message to the corresponding processor for processing, which can solve the problem of insufficient session table items of the P4 programmable chip, reduce hardware costs, have low latency and no packet loss, have strong expandability, flexible management and control, and convenient upgrades.

[0064] In some examples, the managing the P4 programmable chip sends the data message to the corresponding target processor for data processing based on the message type, including:

[0065] In the case where the message type is the control message, managing the P4 programmable chip to send the control message to the X86 processor for data processing;

[0066] and / or,

[0067] In the case where the message type is the stateless message, managing the P4 programmable chip to perform data processing on the stateless message;

[0068] and / or,

[0069] In the case where the message type is the stateful message, the P4 programmable chip is managed to send the stateful message to the NP network processor for data processing.

[0070] For example, when the data message is a control message, the control message is handed over to the X86 processor for processing through the P4 programmable chip. Since the control message has a higher level of importance, the X86 processor can process the control message by virtue of its own stability advantage, thereby ensuring the stability of the network switching device.

[0071] For stateless messages, that is, stateless services, the processing of a single request does not depend on other requests. In other words, all the information required to process a request is either included in the request or can be obtained from the outside (such as a database). The chip or server itself does not store any information. The stateless message is handed over to the P4 programmable chip for processing, and the fast processing speed can be used to achieve fast processing of stateless messages. At the same time, since stateless messages have no memory requirements, the defect of low memory of the P4 programmable chip can be overcome.

[0072] For stateful messages, a handshake is used to connect and the stateful messages are handed over to the NP network processor for processing. By establishing a session pool, the connected session is called to reduce the time spent on repeatedly establishing connections. The NP network processor data plane performs session search and creation functions, and designs an efficient ultra-large session storage architecture, which can effectively solve the problem of insufficient session table entries.

[0073] In summary, the data flow processing method provided in the embodiment of the present application can improve the stability of the control message by having the control message processed by the X86 processor, can realize fast processing of the stateless message by having the stateless message processed by the P4 programmable chip, and can effectively solve the problem of insufficient session table entries by having the stateful message processed by the NP processor.

[0074] In some examples, the method further includes:

[0075] Control the NP network processor to search or build a session link based on the stateful message;

[0076] Instruct the NP network processor to perform data exchange with the external device through the P4 programmable chip according to the session link.

[0077] Exemplarily, if there is a current session connection with a stateful message in the NP network processing, the historical session connection is called; if there is no historical session connection, a new session connection is constructed; after the session connection is established, data is interacted with the external device through the P4 programmable chip.

[0078] In some examples, the method further includes:

[0079] Control the NP network processor to build a session link pool based on the session link;

[0080] The NP network connection processor is controlled to perform timeout management on the session connection pool.

[0081] Exemplarily, a session connection pool is constructed by session connections established by an NP network processor. When there is the same network request, it is checked whether there is a matching session connection in the session pool. If so, the session connection is reused. If not, a new session connection is created. At the same time, the NP network connection processor also manages historical session connections in the session pool, clears historical session connections that have not been called for a long time, or deletes historical session connections that have not been called successfully, thereby freeing up memory in the NP network processing.

[0082] NP network processor devices are usually composed of several microcode processors and several hardware coprocessors. Multiple microcode processors are processed in parallel inside the network processor, and the processing flow is controlled by pre-programmed microcode. For some complex standard operations (such as memory operations, routing table lookup algorithms, QoS congestion control algorithms, traffic scheduling algorithms, etc.), hardware coprocessors are used to further improve processing performance, thereby achieving an organic combination of business flexibility and high performance.

[0083] In summary, the data stream processing method provided in the embodiment of the present application builds and manages a session pool through an NP network processor, manages historical session connections, promptly clears timed-out session connections, and releases the memory of the NP network connection processor.

[0084] In some examples, the method further includes:

[0085] Control the NP network connection processor to obtain the flow information and weight information of each session connection;

[0086] Instruct the NP network connection processor to share the specific session connection whose flow information is less than the preset flow and whose weight information is greater than the preset weight with the X86 processor;

[0087] Manipulate the X86 processor to manage the specific session connection.

[0088] Exemplarily, the NP network connection processor analyzes the flow information and weight information of the session connection. The weight information can be determined based on a lookup of a preset weight information table, and the flow information can be obtained based on real-time flow monitoring. Due to the flow limitation of the X86 processor, the present application preferentially uses the NP network connection processor to process stateful message data to meet large flow requirements, and then screens the flow information and weight information corresponding to the session connection, and shares the session connection with a weight greater than a preset weight and a flow information less than a preset weight, that is, a specific session connection with a relatively important weight but a small flow with the X86 processor, and manages the specific session connection using the stability of the X86 processor.

[0089] In summary, the data flow processing method provided in the embodiment of the present application can meet the large flow requirements of stateful message data through the NP network connection processor, and at the same time, the flow information and weight information of the session connection are screened through the NP network connection processor to select specific session connections with large weights but small flow, and the specific session connections are handed over to the X86 processor for management, thereby improving the stability of session connection management.
