Problems solved by technology

[0004] However, for small and medium-sized networks, the existing static management methods can barely realize the establishment, management and maintenance of network paths. For large-scale networks, due to the large amount of configuration, the management and maintenance are also very complicated, and the flexibility of the network not good

Abstract

The invention provides a method for realizing dynamic routing, so as to realize dynamic management and maintenance of MPLS (Multi Protocol Label Switching) network and paths under a non-IP (Internet Protocol) forwarding scene. The method comprises the following steps of: building a DCN (Data Communication Network) channel between two non-IP forwarding nodes, wherein the non-IP forwarding nodes are the nodes which do not support IP message forwarding; and transmitting the routing protocol information among the non-IP forwarding nodes through the DCN channel. In comparison with the prior art, on one hand, the method for realizing dynamic routing provided by the embodiment of the invention is not dependent on the IP paths, namely, the method can finish routing information interaction even among the non-IP forwarding nodes so as to build dynamic routing, on the other hand, the method can reduce the configuration load, and can be suitable for management and maintenance of large-scale networks, so that a dynamic routing protocol and a signaling protocol are more flexible to use.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for realizing dynamic routing. Background technique [0002] MPLS-TP (Multiple Protocol Label Switching Transport Profile, MPLS-TP) is a transport-oriented MPLS technology, based on the basic architecture and forwarding mechanism of the existing MPLS technology, it expands the transport-oriented features of MPLS, mainly Including several levels such as Operation Administration Management (OAM), protection, control, and management, technologies related to MPLS-TP are currently being standardized by the Internet Engineering Task Force (IETF). [0003] Most of the existing control protocols themselves are grouped based on the Internet Protocol (IP). Generally, the use of the control protocols is implemented by exchanging and forwarding IP data packets on interfaces with IP capabilities. MPLS-TP technology needs to support both IP forwarding and non-IP forwardin...
