Embodiment Construction

[0022] figure 1 It is a schematic structural diagram of the system of the IP network of ASON based on the IP routing processing method based on the ASON optical network of the present invention, as figure 1 As shown, the system includes: ASON optical network 11, multiple IP backbone routers 12, multiple access networks 13 and multiple user terminals 14; wherein, ASON optical network 11 and multiple IP backbone routers 12 act as an IP network ASON backbone network of the system. The IP backbone router 12 connects the access network 13 to the ASON optical network 11 . Each access network 13 is connected to the ASON backbone network through at least one IP backbone router 12 , so that user terminals 14 are connected to the ASON optical network 11 through the access network 13 .

[0023] At the same time, according to certain network planning, each IP backbone router 12 establishes ASON permanent connection with some other backbone routers 12 on the ASON backbone network. At th...

Abstract

The invention provides an IP router processing method and device based on an ASON optical network. A broadcasting sub-network is built on the ASON optical network. The method comprises: a first IP backbone router receives an IP packet sent by a first access network; on the basis of an IP destination address in the IP packet, and according to the longest prefix match principle, a local router information database query is done, and if multiple items of a router table are matched with the IP destination address, one of the multiple items is picked as the optimal router table item and an IP backbone router of the optimal router table item is notified to be a second IP backbone router; a local backbone router table query is done, and if an identifier of an ASON connection of the first IP backbone router to the second IP backbone router exists, the IP packet is sent to the second IP backbone router via the ASON connection according to the identifier, so that the IP packet received by the second IP backbone router is sent to a second access network.

Description

technical field [0001] The invention relates to communication technology, in particular to an ASON optical network-based IP routing processing method and device. Background technique [0002] Currently, the Internet can be divided into two levels in terms of routing structure: Inter-domain and Intra-domain. For the inter-domain level, the Internet is composed of multiple autonomous systems (Autonomous Systems; AS for short). Wherein, each autonomous system is an independent management domain, which is composed of a group of routers and other network devices with the same routing policy connected to each other, and is usually owned by a certain Internet Service Provider (Internet Service Provider; ISP for short). In addition, each autonomous system corresponds to a number, which may be called an AS number, and the AS number is an unsigned integer. An intra-domain routing protocol or an inter-domain routing protocol is run in the autonomous system; for example, the intra-dom...
