Message control method and equipment

Abstract

The invention discloses a message control method and message control equipment. The method comprises the steps that AFTR (Address Family Translation Router) equipment is used for receiving an IPv6 message of B4 equipment, wherein the IPv6 message takes an IPv6 head, and a source address of the IPv6 head is an IPv6 tunnel address of the B4 equipment; the AFTR equipment is used for the existing corresponding linking number of the IPv6 tunnel address of the B4 equipment; if the linking number does not reach a limited numerical value of the linking number, the AFTR equipment is used for continuously processing the IPv6 message; if the linking number reaches a limited numerical value of the linking number, the AFTR equipment discards the IPv6 message. In the embodiment of the message control method, the sources of the AFTR equipment cannot be ensured to be exhausted, so as to prevent the influence on the user service quality due to resource exhaustion; furthermore, the influence on the processing property of the AFTR equipment can be prevented, the serious delay on the network can be prevented, and normal users can visit a target IPv4 network without any influence.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a message control method and equipment. Background technique [0002] Such as figure 1 As shown, it is a schematic diagram of a DS-Lite (Dual-Stack Lite) network. When a client in the IPv4 network needs to access the destination IPv4 network through the IPv6 network, the IPv4 packet sent by the client will be Pass through B4 (Basic Bridging Broad Band, gateway basic bridging broadband unit) equipment. Based on the IPv6 tunnel between the B4 device and the AFTR (Address Family Transition Router, address family transition router unit), the B4 device performs IPv6 tunnel encapsulation on the IPv4 message, and encapsulates a layer of IPv6 header on the IPv4 message. Wherein, the source address of the IPv6 header is the IPv6 tunnel address of the B4 device, and the destination address is the IPv6 tunnel address of the AFTR device. Further, the B4 device sends the pac...

Problems solved by technology

[0003] In the above implementation, if a client connected to the B4 device maliciously initiates a large number of IPv4 packets to access the destination IPv4 network, the AFTR device will receive a large number of IPv4 packets, which will affect the processing performance of the AFTR device and may cause serious network problems. Delay, which seriously affects normal users' access to the destination IPv4 network
