Embodiment 1

[0070] This embodiment provides a method for enhancing message identification capabilities, such as figure 1 As shown, the method includes:

[0071] 101. The forwarding board receives the message.

[0072] 102. The forwarding board acquires at least one type of forwarding state information of the packet according to the packet attribute of the packet.

[0073] For example, the message attributes may include: message field information and an index value of the message; the index value may include at least one of the following parameters: destination IP information, media access control MAC address information and quality of service QoS information .

[0074] Optionally, the obtaining at least one forwarding status information of the message according to the message attribute of the message includes:

[0075] Analyzing the message field information to obtain the message type information of the message, using the message type information as the forwarding state information; or...

Embodiment 2

[0086] This embodiment provides a method for enhancing message identification capabilities, such as figure 2 As shown, the method includes:

[0087] 201. The main control board receives the message sent by the forwarding board.

[0088] 202. The main control board identifies the extended information field of the packet, and acquires a first identifier included in the extended information field.

[0089] Wherein, the first identifier is used to indicate a kind of forwarding state information of the message, and the first identifier corresponds to the forwarding state information of the message one by one. After obtaining the first identifier, the main control single board can know the forwarding status information of the message, and then perform corresponding processing operations on the messages containing different forwarding status information according to system needs.

[0090] 203. The main control board performs an operation corresponding to the first identifier on th...

Embodiment 3

[0094] This embodiment provides a method for enhancing message recognition capability. The message has the forwarding state information of the hit routing table on the forwarding board, and the forwarding board adds a corresponding identifier to the message so that the main control board can recognize that the message has the The state of the routing table, such as image 3 As shown, the method includes:

[0095] 301. The forwarding board receives the message.

[0096] Among them, such as Figure 4 As shown, the structure of the received message is mainly composed of two parts: the message payload and the message attribute.

[0097] 302. The forwarding board performs an operation of searching the routing table according to the destination IP information of the received message, and obtains state information of the message hitting the routing table.

[0098] Wherein, the destination IP information of the message is an attribute of the message, called an index value, and the ...

Abstract

The embodiment of the present invention discloses a method and device for enhancing message identification capability, which relate to the field of communication technology. The method includes: receiving a message; acquiring at least one of the message attributes according to the message attribute of the message Forwarding status information; adding at least one first identifier in the extended information field of the message, where the first identifier is used to represent the forwarding status information of the message; sending the message to the main control single board text, so that the main control single board can identify the first identifier and obtain the forwarding state information of the packet. The present invention is applicable to message forwarding inside and between network forwarding devices.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for enhancing message identification capability. Background technique [0002] The message identification function of network forwarding devices (such as routers and switches, etc.) is mainly realized through TCAM (Ternary content addressable memory, ternary content addressable memory). In a network device system, different components of a network device occupy different TCAM resources, which leads to great differences in the fineness of identification of the same packet within the network device. [0003] Taking the TCAM capabilities of the main control board and the forwarding board as an example, the TCAM capability of the main control board is much weaker than that of the forwarding board. Often unavailable. For example, when a certain IP packet arrives at the forwarding board, the forwarding board can search the routing table according to the des...
