Abstract

The embodiment of the present application provides a method and device for obtaining an address. The method includes: the edge device receives the mapping address request message carrying the first EID sent by the ITR; the ITR is located in a layered network connected to the edge device; and then, the edge device Detecting whether there is a first mapping address including the first EID in the pre-stored mapping addresses; the first mapping address includes the first EID and the first RLOC of the first ETR connected to the virtual machine corresponding to the first EID; the first ETR and The ITRs are located in different hierarchical networks; finally, if the edge device detects the first mapped address, it sends the first mapped address to the ITR. By applying the embodiment of the present application, the time consumption of requesting addresses across hierarchical networks is reduced, and the timely forwarding of services is ensured.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for obtaining an address. Background technique [0002] The number of addresses and identification information in the network is huge and the distribution is irregular. In order to simplify operations and facilitate maintenance of huge data, distributed networking is often used at present. [0003] In a distributed network, it includes an ALT (Alternative) network and multiple layered networks; the ALT network includes edge devices of multiple layered networks, and the layered network includes virtual machines, ITR (Ingress Tunnel Router, ingress direction tunnel router), MR (Map Router, mapping router), MS (Map Server, mapping server) and ETR (Egerss Tunnel Router, outbound tunnel router), etc. In addition, after the virtual machine is connected to the ETR, the ETR registers the EID (Endpoint Identifiers) of the virtual machine with the ...
