Abstract

The present disclosure relates to a session establishment method and device. The method includes: receiving a first message from a second device, the first message including a remote transmission address corresponding to the second device; determining a local transmission address corresponding to the first device according to the remote transmission address corresponding to the second device address; according to the source address of the first message, determine the local transfer address corresponding to the second device; according to the local transfer address corresponding to the first device and the local transfer address corresponding to the second device, between the first device and the second device Establish a Label Distribution Protocol LDP session. The session establishment method and device disclosed in the present disclosure can realize the addition of a remote transmission address in the Hello message of the LDP protocol, so that the local transmission address of the device can be directly determined by the remote transmission address of the remote device. The process no longer needs to be concerned with configuring the local transport address for the device.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular, to a method and device for establishing a session. Background technique [0002] LDP (Label Distribution Protocol, Label Distribution Protocol) is a protocol in an MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) network, and is used to dynamically establish an LSP (Label Switched Path, Label Switching Path). Through the LDP, the LSR (Label Switching Router, label switching router) can map the IP (Internet Protocol, Internet Protocol) routing information of the network layer to the label switching path of the MPLS. LDP can run on IPv4 network or IPv6 network, and can also run on a network where IPv4 and IPv6 coexist. [0003] An LDP session refers to an LDP connection established on a TCP (Transmission Control Protocol, Transmission Control Protocol) connection, and is used to exchange FEC (Forwarding Equivalence Class, Forwarding Equivalenc...
