Abstract

The invention discloses a user access method, system and device, and relates to the field of data communication. The method comprises: a vBRAS forwarding plane device encapsulates an SRv6 header for a received first protocol user access request message, and sends the first protocol user access request message encapsulated with the SRv6 header to a vBRAS control plane device, the SRv6 header comprising a field for identifying function information; then, the vBRAS control plane equipment processes the first protocol user access request message of the packaged SRv6 header, generates a first protocol session message after completing a user access request through protocol interaction, packages the SRv6 header for the first protocol session message, and sends the first protocol session message of the packaged SRv6 header to vBRAS forwarding plane equipment, so that a user accesses a network. According to the disclosure, the SRv6 protocol is expanded, and the SRv6 header is packaged for the transmission message, so that the unification of the forwarding and control separation vBRAS interface can be realized.

Description

technical field [0001] The present disclosure relates to the field of data communication, and in particular to a user access method, system and device. Background technique [0002] SRv6 is a technology combining IPv6 and SR (Segment Routing, segment routing). Relying on the flexibility of IPv6 addresses, SRv6 supports the tunnel function by extending the IPv6 packet header, thereby canceling the MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) forwarding bearer technology, and unifying ordinary IP forwarding and tunnel forwarding, which can greatly reduce The network protocol simplifies operation and maintenance and effectively reduces OPEX (Operating Expense, operating cost). [0003] In the vBRAS (Virtual Broadband Remote Access Server, virtualized broadband remote access server) scheme of separation of transfer and control, VxLAN (Virtual Extensible Local Area Network, Virtual Extended Local Area Network) is used to carry user Layer 2 access packets...
