Data forwarding method and device

Abstract

The invention discloses a data forwarding method and device and belongs to the technical field of communication. The method includes: a first message is received from a tunnel, wherein the first message includes an external-layer IP head, a tunnel head and an inner-layer Ethernet head, and the tunnel is ended and if corresponding information is not found in an MAC table according to an SMAC address in the inner-layer Ethernet head, a corresponding relation between the SMAC address in the inner-layer Ethernet head and a source IP address in the external-layer IP head is established in the MAX table; and when a second message is received, wherein the second message includes an Ethernet head, the MAC table is inquired according to a DMAC address in the Ethernet head of the second message and if the DMAC address is found, tunnel package is performed according to an IP address corresponding to the DMAC address in the MAC table and then the packaged message is forwarded. The device includes an establishment module and a forwarding module. The data forwarding method and device realize automatic studying and forwarding of a forwarding plane.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for data forwarding. Background technique [0002] Network virtualization can hide the implementation details of the physical network, so that from the user's point of view, what you see is your own logical network, without having to care about how the physical network transmits user business data. With the use of network virtualization technology, a variety of logical networks can be virtualized from the same physical network, which facilitates the provision of diversified services and improves the flexibility and scalability of service deployment. [0003] Network virtualization based on three layers (English: Network Virtualization over L3, abbreviation: NVO3) is a network virtualization technology that supports the realization of network virtualization on the physical network of the three layers, namely the network layer (English: network layer)...

AI Technical Summary

Problems solved by technology

[0006] However, the above-mentioned manual way of configuring tunnels is cumbersome, lacks flexibility, is difficult to expand the network, and cannot automatically adapt to changes in the network; while the method of running the control plane protocol requires the control plane to participate in the forwarding process, which not only requires complex control of network operation layer protocol, it also requires the cooperation of the forwarding plane and the control plane to complete, and the implementation is more complicated
