Stream label allocation method and system and stream label request device and allocation device

Abstract

The invention discloses a distributing method for a flow label, comprising the steps that: a request is sent to a flow label distributing device in network side by a flow label request device in user device to generate a first request massage including a flow class; corresponding flow label is generated by the flow label distributing device in network side according to the flow class, and a first response massage including the flow label is returned to the flow label request device in user device. The invention further discloses a flow distribution system, a flow label request device and a flow label distribution device. The invention can effectively control the generation and distribution of the flow label by a network side device.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a flow label allocation method, a flow label allocation system, a flow label request device and a flow label allocation device. Background technique [0002] With the introduction of concepts such as network convergence, Triple-play (triple-play service), and All in IP, IP networks are increasingly becoming the infrastructure of the next-generation information network. However, due to the inherent characteristics of the IP network itself, such as openness, freedom, and best effort, the IP network is still far from an operable and manageable telecommunication network. [0003] Currently, the IP network generally uses the IPv4 (Internet Protocol Version 4, Internet Protocol Version 4) protocol as the network layer protocol. Emerging real-time services such as VoIP (Voice over IP) and IPTV have put forward higher requirements for QoS (Quality of Service) provided by IP netwo...

AI Technical Summary

Problems solved by technology

[0006] 1. Since the user equipment allocates flow labels by itself, the network side equipment cannot effectively control the allocation of flow labels;

[0007]2. Since the user equipment assigns the flow label itself, the network side equipment cannot know the status information of the flow label allocated by the user equipment, so it is difficult for the network side equipment to distinguish which flows Labels are valid, which ones are maliciously deceived, so that it is impossible to prevent illegal users from forging flow labels to carry out service theft and denial of service (DoS) attacks (DoS attacks are a special case of service theft attacks, when the theft of services exhausts forwarding resources. DoS attack)
