Embodiment Construction

[0063] The technical solution in this application will be described below with reference to the accompanying drawings.

[0064] figure 1 It is a schematic diagram of an application scenario provided by the embodiment of this application. This application scenario involves packet forwarding, and it is mainly used in the mixed deployment of X-Lean devices and traditional switches. Such as figure 1 As shown, there are mainly three types of switches involved, and the "S" device is a traditional switch without any changes, and the way of table lookup and forwarding is still used. The "X" device (simplified device) is an access or aggregation switch, which only performs direct forwarding and has no MAC entry. The "1" device is the core switch and the control center of the entire network, which carries centralized routing and forwards the traffic of the entire network. The embodiment of this application mainly involves two aspects. One is the processing of the uplink message by t...

Abstract

The invention provides a message forwarding method and a switch. The method comprises the following steps: a first switch generates a first downlink message; the first downlink message comprises a Y +1 layer Ethernet header; an inner-layer Ethernet header in a Y + 1-layer Ethernet header of the first downlink message comprises a first destination MAC address, a first source MAC address and a first Ethernet type; the first destination MAC address is the MAC address of the first terminal device; each layer of outer-layer Ethernet header in Y + 1 layers of Ethernet headers of the first downlinkmessage comprises a second destination MAC address, a first source MAC address and a first Ethernet type; the second destination MAC address in each layer of outer layer Ethernet header sequentially corresponds to the MAC addresses of Y switches of the first type, each layer of outer layer Ethernet header comprises the port number of the corresponding switch of the first type, and Y is an integergreater than or equal to 1; and the first switch forwards the first downlink message. Hybrid networking of new equipment and a traditional switch can be realized.

Description

technical field [0001] The application relates to the communication field, in particular to a message forwarding method and a switch. Background technique [0002] Carriers or enterprises generally do not want to be bound by a single vendor when deploying networks. In addition, in scenarios where switches are gradually upgraded or old ones are simply reused, mixed deployment of new devices and traditional switches will occur. Therefore, it is particularly important for new devices to support mixed deployment with traditional switches. [0003] In the simplified enterprise network architecture, there are no traditional switches, but only simplified devices. The core switch is the control center of the entire network, which carries centralized routing and forwards the traffic of the entire network. The minimalist device can be used as an access switch or an aggregation switch, and only performs direct forwarding without a media access control (media access control, MAC) ent...
