Embodiment Construction

[0060] The method of the present invention requires that the two CE devices that transmit the message be in the same address network segment during the implementation process, such as figure 1 As shown, the user-side edge device A (CE-A) and the user-side edge device B (CE-B) must be in the same address network segment.

[0061] In addition, still as figure 1 As shown, CE-A is connected to the edge device A (PE-A) provided by the operator through Ethernet or VLAN (Virtual Local Area Network), and CE-B is connected to the edge device B (PE-B) provided by the operator through point-to-point Protocol (PPP) or Asynchronous Transfer Mode (ATM) connections.

[0062] The specific implementation of the method of the present invention is as follows figure 2 shown, including:

[0063] Step S210, configure the interface address between the PE device and the local user-side edge device CE on the operator edge device PE device as the IP address of the opposite end CE device.

Abstract

Present invention relates to a method for realizing MPLS network intercommunication based on hetero medium. Said method configures the interface address between said PE equipment and said end user side equipment CE as the opposite end CE equipment, generating ARP item corresponded by opposite end CE equipment, finally communicating between hetero media based PE equipment and ARP item. Said method can ensures the said end CE to provide right response without depending on free ARP function, and only same network channel PE can make response to CE transmitted ARP request.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for realizing MPLS network intercommunication based on heterogeneous media. Background technique [0002] With the development of society, the trend of economic globalization is becoming more and more obvious. More and more enterprises are establishing branches, and the employees of the company are also moving along with the establishment of branches. Therefore, it is urgent for telecom operators to provide two-layer chain Road connection, so that each branch of the enterprise organizes its own enterprise network, and at the same time, the employees of the company can easily access the enterprise internal network from outside the enterprise. [0003] Initially, telecom operators provided enterprises with Layer 2 links in the form of Leased Lines. However, this method not only takes a long time to construct, is expensive, and is difficult to manage. Therefore, with the rise of ...
