Embodiment Construction

[0037] The specific realization of the scheme of the present invention includes:

[0038] The interface of the communication device is divided into a protocol trusted interface and a protocol unknown interface. The protocol trusted interface refers to an interface for which protocol interaction has been established; when a communication device enables a certain protocol, assign n different priorities to the protocol The queues are used to send different types of messages of the protocol, and the n is a natural number greater than or equal to 2; the interface that sends the different types of messages of the protocol is used as the trusted interface of the default protocol; it is judged as the default protocol Whether the interface of the trusted interface is a protocol trusted interface, if not, use the preset protocol trusted interface as the protocol trusted interface, and send different types of packets of the protocol from n queues with different priorities.

Abstract

The invention discloses a protocol message forwarding method. The method is characterized in that: dividing interfaces of communication equipment into a trustworthy protocol interface and an unknown protocol interface, wherein the trustworthy protocol interface is the interface which establishes protocol interaction; when the communication equipment enables a protocol, distributing queues with n different priorities for the protocol, wherein the queues are used to push different types of messages of the protocol and the n is a natural number which is great than or equal to two; taking the interface which sends the different types of messages of the protocol as the preset trustworthy protocol interface; determining whether the preset trustworthy protocol interface is the trustworthy protocol interface; if the preset trustworthy protocol interface is not the trustworthy protocol interface, taking the preset trustworthy protocol interface as the trustworthy protocol interface and pushing the different types of messages of the protocol respectively from the n different priority queues. The invention also discloses the communication equipment used in the protocol message forwarding. By using the method and the equipment of the invention, abnormal operation of the communication equipment caused by forging the protocol messages can be avoided.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a protocol message forwarding method and communication equipment. Background technique [0002] For mainstream high-end data communication equipment, the control unit and forwarding unit are separated. The forwarding unit completes the exchange and forwarding of messages, and the control unit completes device control management, protocol processing and other functions to guide the forwarding unit to process messages. . Among them, the control unit will run multiple protocols at the same time, and exchange protocol messages with other communication devices. These interactive protocol messages generally enter the forwarding unit through the service interface, and the forwarding unit analyzes and identifies protocol messages such as message addresses and protocol types. After the characteristics of the file are uploaded to the control unit. [0003] The control unit is ...
