Route publishing method, network element, system and equipment

Abstract

The invention provides a method for releasing a route, which is applied to a third-layer network in an open system interconnection (OSI) model, the network comprises a control plane network element and a forwarding plane network element which are connected with each other, and the method comprises the following steps that: the forwarding plane network element receives a message of which a source IP address is a first IP address, and the forwarding plane network element determines that the first IP address is not authenticated; the forwarding plane network element sends an authentication request including the first IP address to a control plane network element, and the forwarding plane network element receives first session information from the control plane network element; and the forwarding plane network element issues first routing information according to the first session, wherein the destination address of the first routing information is the first IP address. According to the method, the problem that in a third-layer network of an OSI model, under the condition that user equipment is connected with a plurality of APs of different BNGs or routers are switched back and forth, the state of network interruption cannot be kept can be solved.

Description

technical field [0001] The present application relates to the field of communications, and in particular to a method, network element, system and equipment for issuing routes. Background technique [0002] In recent years, with the rapid development of network technology, people's dependence on it is gradually increasing. The Internet has penetrated into thousands of households. Almost all consumer places such as shopping malls, restaurants, hotels, coffee shops, etc. provide their customers with In addition to wireless services, almost all homes, offices, schools and other places have covered wired services, and surfing the Internet has become an important part of most people's study, work and life. [0003] When a user uses a WLAN or a router to access the third-layer network in the Open System Interconnection (OSI) model, it often occurs between different network access points (Access Point, AP) or routers. The case of jumping back and forth. However, in the third-layer...
