Problems solved by technology

In particular, due to the different 4over6 transition mechanisms adopted, there are great differences in the data packet forwarding policies configured on the edge routing devices of the IPv6 access network
For the forwarding policy located in the operator-side device, the operator's network management personnel often need to maintain it through manual static CLI configuration (for example, the binding entry on lwAFTR in the lw4over6 mechanism, and the BR in MAP-E / T address mapping rules), however, for CE devices on the user side, these forwarding rules are difficult to remotely maintain through effective configuration means

Embodiment Construction

[0022] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0023] Such as figure 1 As shown, in the forwarding policy architecture of the 4over6 access network, the following modules are included:

[0024] NETCONF server (NETCONF Server): The NETCONF server is deployed in the IPv6 network border router in the 4over6 transition scenario. On the one hand, the NETCONF server is responsible for interacting with the data model built in the IPv6 network border router and reading the data defined by the model. Configure content; on the other hand, accept configuration requests from NETCONF clients and perform corresponding operations. At the same time, the NETCONF server also supports the event notification mechanism defined by the model.

[0025] NETCONF client (NETCONF Client): The NETCONF client is deployed in the network management device on the carrier side and is responsible for interacting with the NE...

Abstract

A method for configuring 4over6 access network forwarding policies based on the NETCONF protocol, in a 4over6 access network transition scenario, by constructing a forwarding policy data model on an IPv6 network border router, and using the NETCONF protocol to configure and manage the content defined in the data model In this way, the operator can remotely connect to the managed routing device, and achieve the purpose of configuring and maintaining the corresponding data forwarding strategy table items; the present invention uses data modeling for the data forwarding strategy to define the forwarding strategy that needs to be configured and managed Contents, the present invention uses the NETCONF management protocol to remotely access the border router and combines the content defined by the data model to realize the remote configuration and management of the data forwarding strategy of the IPv6 network border router by the operator.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for configuring a 4over6 access network forwarding strategy based on the NETCONF protocol. Background technique [0002] With the depletion of IPv4 addresses and the continuous application and popularization of IPv6 addresses, a series of problems caused by the incompatibility of IPv4 and IPv6 protocol stacks make the transition from IPv4 to IPv6 a major research content of the current Internet development. Divided according to the network structure, the transition scenarios from IPv4 to IPv6 are mainly divided into backbone network-based transition and access network-based transition. Among them, the 4over6 transition problem based on the access network mainly solves the problem that end users located in the terminal IPv4 LAN access the IPv4 Internet by crossing the IPv6 access network. The softwire working group established in the IETF (InternetEngineering Task F...
