Problems solved by technology

[0003] VXLAN (Virtual Extensible Local Area Network, Virtual Extended Local Area Network) is a tunneling technology that can establish a Layer 2 Ethernet network tunnel on the basis of a Layer 3 network, thereby realizing cross-regional Layer 2 interconnection, which is a good solution to existing problems. There is a problem that VLAN technology cannot meet the needs of large Layer 2 networks
[0004] The existing VXLAN technology uses a pair of VTEPs to carry the services of multiple tenants. In the process of transmission between VTEP nodes, it is necessary to forward packet packets by hop-by-hop network nodes, followed by routing and forwarding based on IP. The path The optimality cannot be guaranteed, resulting in an increase in packet forwarding delay, and it is also impossible to differentiate the services of different tenants, that is, the demand for traffic isolation and delay requirements of high-quality users cannot be guaranteed

Abstract

The invention discloses a method and device for carrying VXLAN services through a FlexE channel, wherein the method includes: a controller determines the mapping relationship between a VNI, a VXLAN tunnel destination address and a FlexE channel identifier according to user service requirements and VXLAN tunnel information; Requirements include bandwidth, delay and isolation requirements for cross-data center user services; VXLAN tunnel information includes source VTEP identifiers, destination VTEP identifiers, and VNIs; VNIs are used to identify different users; the first data center gateway passes The FlexE channel sends VXLAN packets to the second data center gateway; the second data center gateway receives the packets and sends them to users corresponding to the VNI. The present invention can carry VXLAN service through the FlexE channel, thereby realizing the differentiated service of the service and the traffic isolation requirement of the user, and also reducing the transmission time delay of the service.
