Problems solved by technology

When the VPLS MAC entries on UPE1 are used up, it will not be able to learn the MAC addresses of new users, so the packets sent to these new users will be forwarded in broadcast mode, and broadcast forwarding will waste network bandwidth resources , will also degrade the processing performance of UPE1

Embodiment 1

[0016] figure 2 It is a preferred flow chart of the configuration method of the VPLS MAC entry space according to the embodiment of the present invention, and it includes the following steps:

[0017] S202, when the edge device UPE on the service provider network close to the user side receives the message from the network side, perform the process of not learning the MAC information of the message from the network side in the VPLS MAC table on the UPE operate;

[0018] S204. When the UPE receives a message from the user side, perform an operation of learning the MAC information of the message from the user side in the VPLS MAC table on the UPE; wherein the UPE is connected to a network device The side of the UPE is the network side, and the side where the UPE is connected to the user equipment is the user side.

[0019] In this preferred embodiment, the UPE does not learn the network side message after receiving the network side message, which reduces the VPLS MAC entry s...

Embodiment 2

[0026] see figure 1 , A VPLS full-mesh link is established between equipment PE1, PE2, and PE3. User CE1 is connected to PE1, CE2 is connected to PE2, and a UPE1 is connected to PE3, and users CE3, CE4, and CE5 are connected to UPE1. . Assume that CE1 needs to communicate with CE5. The specific implementation process is as image 3 As shown, the configuration method of the VPLS MAC entry space according to the embodiment of the present invention includes the following steps:

[0027] Step S0, PE1 receives the message from CE1, first learns the MACA of CE1 and generates a VPLS MAC entry on PE1: the key value is MAC A of CE1, and the outbound interface is Gigabit Ethernet interface Gei 1 / 1. Then use the MAC E of CE5 to search the VPLS MAC table. If no result is found, the packet is broadcast and forwarded, and the packet is sent to PE2 and PE3.

[0028] Step S1, after PE3 receives the message from PE1, it first learns the MACA of CE1 and generates a VPLS MAC entry on PE3: ...

Embodiment 3

[0039] Figure 4 is a preferred structural diagram of a device for configuring a VPLS MAC entry space according to an embodiment of the present invention, which includes: a first execution unit 402, configured to receive When a message from the network side is received, the operation of not learning the MAC information of the message from the network side is performed in the VPLS MAC table on the UPE; the second execution unit 404 is used to receive the message from the user when the UPE When the message of the user side is used, the operation of learning the MAC information of the message of the user side is performed in the VPLS MAC table on the UPE; wherein, the side where the UPE is connected to the network device is the network side, and the The side where the UPE is connected to the user equipment is the user side.

[0040] In this preferred embodiment, the UPE does not learn the network side message after receiving the network side message, which reduces the VPLS MAC e...

Abstract

The invention discloses a method and a device for a collocating virtual private LAN service (VPLS) media access control (MAC) table entry space. The method is as follows: the operation of not learning MAC information of a message at a network side is executed in a VPLS MAC table on a user facing-provider edge (UPE) when the UPE close to provider edge (PE) at a user side, receives the message from the network side; and the operation of learning the MAC information of the message at a user side is executed in the VPLS MAC table on the UPE when the UPE receives the message from the user side, wherein one side at which the UPE and network equipment are connected is the network side, and one side at which the UPE and user equipment are connected is the user side. By using the method and the device of the invention, the problem that the processing performance is degraded due to the exhausted VPLS MAC table entry space on the UPE is solved in the prior art.

Description

technical field [0001] The present invention relates to the communication field, in particular to a virtual private LAN service (Virtual Private LAN Service, VPLS for short) media access control (Media Access Control, MAC for short) entry space configuration method and device. Background technique [0002] VPLS (Virtual Private LAN Service, Virtual Private LAN Service) is a point-to-multipoint L2VPN service provided in a public network. VPLS enables geographically isolated user sites to be connected through MAN (Metropolitan Area Network, Metropolitan Area Network) or WAN (Wide Area Network, Wide Area Network), and makes the connection effect between various sites the same as in a LAN. [0003] Such as figure 1 As shown in , a simple VPLS service network diagram is given. This topology consists of PE (Provider Edge, edge equipment on the service provider network) and UPE (User facing-Provider Edge, PE equipment close to the user side). A VPLS full-mesh link is established ...
