Embodiment Construction

[0053]The invention relates to a method for setting IP priority. By setting the corresponding relationship between IP priority and priority identification, the initial network equipment sends routing information carrying priority identification to other network equipment, and other network equipment stores the routing information in the In the routing information database of the corresponding routing protocol, the routing protocol uses its own routing information database for calculation, and adds the calculated route to the routing table to form a route; after receiving the IP message, other network devices The destination address of the network knows that the IP packet needs to be sent to the initial network equipment, so the other network equipment queries its routing table, and checks back the routing information stored in the routing information database of the routing protocol that forms the routing, the routing information Including the priority identifier, and then acco...

Abstract

This invention discloses a method, a system and a device for setting IP priorities, which sets the PRI of IP messages by Tag region in the interior gateway protocol to increase the flexibility for setting IP PRI in the region to simplify configuration for it. This invention matches with the function of BGP utilizing group attribute to set IP PRI, in this way, the effectiveness of IP PRI can be prolonged in the region by IGP and the QoS solving plan of the entire network can be formed.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method, system and equipment for setting IP priority. Background technique [0002] QoS (Quality of Service) is a common concept in various occasions where there is a relationship between service supply and demand. It is used to evaluate the service provider's ability to meet customer service needs. Nowadays, the continuous emergence of many new services has put forward higher requirements on the service capabilities of IP networks. Users are no longer satisfied with simply delivering packets to their destinations, but also hope to get better results in the forwarding process. Services, such as: support to provide users with dedicated bandwidth, reduce packet loss rate, manage and avoid network congestion, regulate network traffic and set packet priority, etc. [0003] In the prior art, the upper-layer software is mainly used in the domain, and the priority of th...
