IPv4 access policy routing issuing control method and system

Abstract

The invention discloses an IPv4 access strategy route issuing control method, and the method comprises the following steps: when a WAN port of CPE requests to access and allocate an IPv4 address to OLT access equipment in a PPPoE / IPoE mode, issuing a strategy route corresponding to a CPE client network to the OLT access equipment through dynamic authorization of an RADIUS server, and enabling an OLT user session manager to issue a strategy route of a user to a route entry manager. Through the method provided by the invention, the upstream access routing equipment does not need to manually configure the static routing, so that the equipment deployment is convenient, the old equipment and more networking scenes are compatible, and the operation cost is greatly reduced; the flexibility of the system and the deployment flexibility of the CPE gateway equipment are improved, and the scene that the public network address of the CPE downstream network is not dynamically acquired from the OLT equipment is met. The invention also provides a corresponding IPv4 access policy routing issuing control system.

Description

technical field [0001] The invention belongs to the technical field of communication, and more specifically relates to a method and system for controlling delivery of IPv4 access strategy routes. Background technique [0002] First, the technical terms in this patent application are explained and explained: [0003] CPE: Customer Premise Equipment, customer premise equipment, is actually a mobile signal access device that receives mobile signals and forwards them with wireless WIFI signals. [0004] DHCP: Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol. [0005] NAT: Network Address Translation, network address translation, used for translation between network private network addresses and public network addresses. [0006] CR: Core Route, core router, in the Internet, located at the core of the network, mainly used for data packet routing and forwarding, generally a router with a large throughput. [0007] OLT: optical line terminal (optical line...

AI Technical Summary

Problems solved by technology

[0009] For a special networking scenario, that is, the CPE gateway does not have the route publishing function, and the customer network (the customer network is under the CPE) obtains a public network address from another DHCP server through static configuration or DHCP. In this case, it is It is said that the customer network and the CPE do not access the external network through traditional NAT. In this scenario, because the upstream CR does not know the routing information of the customer network, the customer network cannot access the external network.
