Problems solved by technology

In this way, a large amount of forwarding data not only consumes a large amount of equipment resources, but also reduces the security of MSTP services due to the broadcast transmission of data frames
In the prior art, a virtual private network (Virtual Local Area Network, VLAN) is usually used in MSTP equipment to isolate data, but the mode of using VLAN can only isolate the broadcast of the data link layer, and cannot isolate the broadcast of the network layer. However, there are a large number of network layer broadcast packets in the MSTP line.
When the customer equipment can configure VLAN but does not inform the operator of the planned VLAN, and requires complete port isolation, MSTP equipment cannot bear this type of service at present.

Embodiment Construction

[0018] The present invention will be described more fully below with reference to the accompanying drawings. The illustrations in the drawings are schematic, and the same or similar elements are indicated by the same reference numerals in different drawings.

[0019] The basic idea of ​​the present invention is to configure and store port isolation information between ports in the MTSP device. When data enters a certain port, the isolated port of the port is determined according to the port isolation information, and data forwarding to the isolated port is prohibited. For the destination port obtained according to the data address forwarding table, only when the destination port is not an isolated port, data is forwarded to the destination port.

[0020] Fig. 1 shows a flowchart of an embodiment of a data forwarding method according to the present invention.

[0021] As shown in FIG. 1, in step 101, a certain port of the MTSP device receives data.

[0022] In step 103, the ...

Abstract

The invention discloses a method and an equipment for forwarding data among ports of multi-service transport platform equipment. The data forwarding method comprises the following procedures: a port of the multi-service transport platform equipment receives the data; an isolation port of a data receiving port is determined according to the preset port insolating information; forwarding of the received data to the insolating port of the data receiving port is refused. The data forwarding method and the data forwarding equipment of the invention realize isolation among ports and provide safety in data transmission.

Description

technical field [0001] The invention relates to the technical field of optical transmission network, in particular to a data forwarding method and forwarding equipment between ports of Multi-Service Transport Platform (MSTP) equipment. Background technique [0002] In the current MSTP device network application, after receiving the data frame, the Ethernet port of the MSTP device searches the data address forwarding table according to the destination MAC address in the data frame to obtain the destination port of the data frame, and forwards the data frame to the corresponding destination port. , so as to realize the forwarding process of the data frame. If the corresponding destination MAC address entry cannot be found in the data address forwarding table, the data frame is sent to all ports except this port by flooding. In addition, if the port receives a broadcast data frame, it will also send the broadcast data to all ports except this port. In this way, a large amount...
