Problems solved by technology

[0003] When SRv6 implements a strict explicit path, when there are many hops in the network, it is necessary to include the segment identity (SID) of each network node in the SRH header, which will result in a relatively large packet header. Small forwarding methods, or inability to establish connection-oriented paths

Embodiment Construction

[0131] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0132] Currently, the traffic engineering (TE) technology in the network is not easy to use (such as the resource reservation protocol based on traffic engineering extension (RSVP-TE)), which requires flow-by-flow signaling and the soft state of intermediate nodes. Supports millions of flows in the network, that is, complex control protocols can no longer meet the needs of rapid development; on the other hand, the TE requirements of service flows can be bandwidth, delay, jitter, etc. When there are these TE requirements, it is necessary to provide These business flows specify a specific path (assuming that the default shortest path cannot guarantee the quality of service (QoS) of these business flows), therefore, a SR architecture is proposed, such as figure 1 shown.

Abstract

The embodiment of the invention discloses a path establishment method, a data transmission method and device, a network node and a storage medium. The method comprises the steps of generating a first message by a first network node for creating a first path; sending the first message, wherein the first message comprises a first SRv6 segment identity identification (SID) of each network node of the first path, the first SRv6 SID is used for establishing a connection-oriented path, and the first network node is the first network node of the first path.

Description

technical field [0001] The present application relates to the Internet Protocol (IP) network field, and in particular to a path establishment method, a data transmission method, a device, a network node and a storage medium. Background technique [0002] The future network is a network oriented to the fifth generation mobile communication technology (5G) era. In the face of 5G, the bearer network also needs to make corresponding adjustments. Simplification, low latency, and software-defined networking (SDN) / network function virtualization (NFV) are the main development directions in the future. For the next step in the development of 5G networks, users hope to use IPv6 addresses to implement a virtual private network (VPN) more simply. The SRv6 technology uses the existing IPv6 forwarding technology to implement processing similar to label forwarding by extending the header field of IPv6 packets, that is, the Segment Routing Header (SRH). [0003] When SRv6 implements a s...
