Embodiment 1

[0026] An embodiment of the present invention provides a data communication method, which will be described in detail below with reference to the accompanying drawings.

[0027] figure 2 It is a flow chart of the method of the embodiment of the present invention, the method of this embodiment is applied to the station on the RPR ring, please refer to figure 2 , the data communication method of the embodiment of the present invention includes:

[0028] 201: Search the SAS database for the SAS entry corresponding to the destination MAC address and VLAN ID according to the destination MAC address and VLAN ID of the message to be sent;

[0029] When the station on the RPR ring applying the method of this embodiment receives a message that needs to be sent from the outside world, it obtains the destination MAC address and VLAN ID of the message from the message, and uses the destination MAC address and VLAN ID to find the corresponding SAS entry from the SAS database.

Embodiment 2

[0112] An embodiment of the present invention also provides a network device, which will be described in detail below with reference to the accompanying drawings.

[0113] Figure 11 It is a block diagram of the network equipment in this embodiment, the network equipment can be a site on the RPR ring, please refer to Figure 11 , the network equipment mainly includes:

[0114] The first search unit 1101 is used to search the SAS table entry corresponding to the destination MAC address and VLAN ID from the SAS database according to the destination MAC address and VLAN ID of the message to be sent;

[0115] The second search unit 1102 is configured to traverse the RPR topology database to find a target site that matches the SAS entry when the first search unit 1101 finds the SAS entry corresponding to the destination MAC address and the VLAN ID, if The station in the RPR topology database is legal, and the primary MAC address of the station or the secondary MAC address of the ...

Abstract

The embodiment of the invention provides a data communication method and network equipment. The method comprises the following steps: searching for an SAS list item which corresponds to a destination MAC address and a VLAN ID from an SAS database according to the destination MAC address and the VLAN ID of a message needing transmitting; if the SAS list item which corresponds to the destination MAC address and the VLAN ID is found out, traversing an RPR topological database to search for a destination site conforming to the SAS list item; and if the destination site conforming to the SAS list item is found out, transmitting the message to the destination site by a main MAC address. The data communication method and the network equipment provided by the embodiment can effectively solve the problem of probably flooding when RPR sites are communicated by a secondary MAC address so as to improve the bandwidth utilization.

Description

technical field [0001] The invention relates to the communication field, in particular to a data communication method and network equipment. Background technique [0002] With the gradual establishment of broadband value chain and broadband business operation mode, broadband business is gradually becoming the focus of operators to expand business fields, increase revenue and enhance competitiveness. The traditional MAN solutions are mainly SDH (Synchronous Digital Hierarchy, Synchronous Digital Series) or Ethernet. For the SDH method, its advantages are high reliability, meeting the communication requirements of users, and providing protection and fast recovery mechanisms. However, its point-to-point and circuit switching design goals lead to low bandwidth utilization; for Ethernet, its advantages are low cost, simplicity, easy expansion, and convenient transmission and processing of IP packets, but it is in scale, end There are still many problems to be overcome in terms o...
