Description

Transmission path aggregation method, transmission path aggregation device, network switching equipment and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a transmission path aggregation method and apparatus, a network switching device, and a storage medium.

Background

Software-defined networking (SDN) is a novel network architecture, and its idea is to separate a control plane and a forwarding plane of a network, implement centralized control of the network through a centralized controller, flexibly allocate network resources as needed, and provide a good platform for innovation of a core network and application. When the SDN network switching device receives and processes a data packet, it is often in a situation where the data packet received through multiple ports needs to be processed by the same service logic, for example, when the transmission rate of the data packet of the same service is very high, but the transmission rate of a single port of the receiving-end network switching device cannot reach the transmission rate, at this time, the data packet belonging to the same service is received by different ports of the receiving-end network switching device, and is processed by the same service logic in the receiving-end network switching device. The data messages from different data acquisition devices are transmitted to the same receiving end network switching device through different channels, and are processed by the same service logic in the receiving end network switching device.

For the above situation, in the prior art, in the SDN network, corresponding processing logics need to be configured for the data packets received by each port of the receiving-end network switching device one by one, so that the data packets received by the ports execute the same processing actions. Therefore, in the prior art, processing logic needs to be configured for each port, so that the multiple physical transmission paths can be logically consistent.

It should be noted that, although the existing SDN technology can aggregate multiple data packet transmission paths to some extent, the existing SDN technology still has the following problems:

1. fussy and low-efficiency: the same action domains are configured for the processing logic of each port in the specified range one by one, and the method repeatedly configures the same instructions, so that the operation is complicated, and the efficiency is greatly reduced.

2. Poor flexibility: when the forwarding action is changed, in order to ensure that the designated port executes a uniform forwarding action when transmitting the data message, the processing logic corresponding to each port needs to be modified, and the flexibility is low.

3. The occupied resources are more: when the number of ports in the designated range is large and the instruction of the processing logic is complex, the total number of bytes of the processing logic to be set in the network switching device is greatly increased, and the occupied device resources are relatively large.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

As shown in the background section, a Software-defined network SDN (Software-defined networking) is a novel network architecture, and its idea is to separate a control plane and a forwarding plane of a network, to implement centralized control of the network through a centralized controller, to flexibly allocate network resources as needed, and to provide a good platform for innovation of a core network and applications. When the SDN network switching device receives and processes a data packet, it often encounters a situation that the data packet received via multiple ports needs to be processed by the same service logic, for example, when the transmission rate of the data packet of the same service is very high, but the transmission rate of a single port of the receiving-end network switching device cannot reach the transmission rate, at this time, the data packet belonging to the same service is received by different ports of the receiving-end network switching device, and is processed by the same service logic in the receiving-end network switching device; the data messages from different data acquisition devices are transmitted to the same receiving end network switching device through different channels, and are processed by the same service logic in the receiving end network switching device. In order to improve the reliability of data message transmission, the sending-end network switching device transmits the data message to different channels of the receiving-end network switching device, and performs mutual backup on the data message in the channels, and after receiving the data message transmitted by the channels, the receiving-end network switching device needs to execute the same service logic on the data message transmitted by the channels. In order to solve the above problems quickly and efficiently, the invention provides a SDN-based multi-data transmission path aggregation method.

As shown in fig. 1, SDN is a new network architecture, and its main ideas are separation of control plane and forwarding plane, centralized control and scheduling of network resources, and open programmability. SDN is mainly divided into a three-layer architecture: an Application Layer (Application Layer), a Control Layer (Control Layer), and an Infrastructure Layer (Infrastructure Layer). The control plane is separated from the forwarding plane in the SDN network. The control plane node is an SDN Controller and is responsible for network topology calculation, network state monitoring, path calculation, path rule generation and the like. The forwarding plane node is called an SDN switch and is responsible for forwarding data according to the entries in the flow table. The current SDN switches all support the Openflow protocol. The communication between the controller and the switch depends on an Openflow protocol, and the reporting of unknown packets, the reporting of network state and flow statistics, the issuing of flow rules and the like are mainly carried out.

The data forwarding mechanism in the SDN network is greatly different from the packet forwarding mechanism in the conventional IP network, and when the SDN switch forwards a data packet, the action set is first cleared, and the header information of the data packet is matched with the flow table entry in the flow table 0. If the data packet is successfully matched with the flow table entry, the SDN switch may perform a next action according to the instruction entry in the matching entry, such as Apply-actions, clear-actions, goto-table, and the like. In this case, in the Goto-table instruction, matching is started from the next flow table, and multi-stage flow table matching is performed. If the instruction is other instruction, the action set is executed, and the data packet is forwarded to the Group action (if existing) or the Output action. If the SDN switch does not find the flow Table item of the matched data packet, matching a Table-miss flow Table item, and executing corresponding forwarding action according to the Instruction in the Table-miss flow Table item; if the Table-miss does not exist, the packet is discarded.

In the existing SDN technology, corresponding processing logic is configured for data packets received by each port of a receiving-end network switching device in an SDN network one by one, so that the data packets received by the ports execute the same processing action. Therefore, at least one processing logic must be configured for each port to achieve logical consistency of multiple physical transmission paths. The existing SDN technology can aggregate multiple data packet transmission paths to a certain extent, but still has many problems: complicated and low-efficiency: the same action domains are configured for the processing logic of each port in the designated range one by one, and the method repeatedly configures the same instruction, so that the operation is complicated and the efficiency is greatly reduced. Poor flexibility: when the forwarding action is changed, in order to ensure that the designated port executes a uniform forwarding action when transmitting the data message, the processing logic corresponding to each port needs to be modified, and the flexibility is low. The occupied resources are more: when the number of ports in the designated range is large and the instruction of the processing logic is complex, the total number of bytes of the processing logic to be set in the network switching device is greatly increased, and the occupied device resources are relatively large. In order to solve the above problems, the present invention provides a transmission path aggregation method, an apparatus, a network switching device, and a storage medium, and the transmission path aggregation method, the apparatus, the network switching device, and the storage medium provided in the present application are explained and explained in detail through specific embodiments below.

The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment.

Based on the content of the foregoing embodiment, in this embodiment, configuring a service processing logic for a data packet received by a port within the port range includes one of the following:

In this embodiment, a service processing logic may be configured for a data packet received by a physical port in a port set, with the port set as a unit; or configuring service processing logic for data messages received by a physical port which has a mapping relation with the abstract port by taking the abstract port as a unit; it is also possible to configure a service processing logic for a data packet received by a selected physical port by taking the selected physical port as a unit, and this will be explained and illustrated in detail later with reference to the accompanying drawings and embodiments.

Based on the content of the foregoing embodiment, in this embodiment, when a service processing logic is configured for a data packet received by a physical port in a port set by taking the port set as a unit, a matching field of the service processing logic is a port set number.

In this embodiment, as shown in fig. 12, an upper layer application logic, an SDN controller, or an SDN network switching device configures a processing logic for a data packet received by a port set with the port set as a unit, and defines a matching domain of the processing logic as a port set number.

The matching field of the Nth level processing logic is a data message header information flag bit. After the processing logic configuration is completed, first-stage processing logic matching is firstly carried out on data messages transmitted by different ports of the SDN network switching equipment, and after the matching is successful, a specific flag bit is added to the head of the data messages; and then, performing N-level processing logic matching according to the flag bits, so that the successfully matched data messages execute unified processing actions.

N is an integer and is greater than 1.

In this embodiment, as shown in fig. 17, the third processing manner may be processing by group forwarding. The upper layer application logic, the SDN controller or the SDN network switching equipment configures a matching domain of the processing logic for the data messages received by different sub-ports in the port range to be a port number, and an action domain is a forwarding group. Data messages received by different ports of the SDN network switching equipment are forwarded to the group after being processed by the processing logic, and unified processing of the data messages of different ports is realized through the group. In the present embodiment, it should be noted that the group is a set including a series of processing actions.

According to the above technical solutions, in this embodiment, an upper layer application logic, an SDN controller, or an SDN network switching device determines a set of port ranges of the SDN network switching device, and presets one or more processing logics for data packets received by ports within the range. The technical scheme is as follows: the port range is a port set, and the matching domain of the processing logic is a port set number; the port range is a port set, the matching domain of the processing logic is a sub-port number, and the matching rule is that any port number matched in the port set is successful. The port range is an abstract port, and the matching field of the processing logic is an abstract port number. The port range is selected sub-ports, the matching domain of the first-stage processing logic is the sub-port number, and the action domain is as follows: (1) immediately modifying the header information of the data message, and adding a flag bit to the header information of the data message; (2) and forwarding to the Nth stage processing logic. The matching field of the Nth level processing logic is a data message header information flag bit. The port range is selected sub-ports, the matching domain of the first-stage processing logic is the sub-port number, and the action domain is as follows: (1) modifying the metadata field immediately, adding a flag bit in the metadata field, and setting a uniform value; (2) and forwarding to the Nth stage processing logic. The matching field of the Nth stage processing logic is a flag bit in the metadata field. The port range is selected sub-ports, the matching domain of the processing logic is the sub-port number, and the action domain is the forwarding group. Furthermore, the present embodiments provide a way to configure and update a port set or abstract port. An upper layer application logic, an SDN controller, or an SDN network switching device configures a port set or abstract port. The physical port range is configured as a port set. The physical port range is mapped to an abstract port. The receiving end network switching equipment dynamically updates the port set or the abstract port; the receiving end network switching equipment and the sending end network equipment dynamically update the port set through signaling interaction.

The occupied resources are less: according to the method and the device, the processing logic is configured in a mode of taking the port set or the abstract port as a unit, and the resource occupation rate of the processing logic in the SDN network switching equipment is reduced.
