Multi-address space mobile network architecture, method for registering host information, and method for sending data

摘要

A multi-address space mobile network architecture is disclosed, in which edge networks (ENs) are connected to a core network (CN) through core edge routers (CERs). A distributed hash table (DHT) set in the CN is adapted to not only store or update a mapping relation between a CER ID and CER location information in the CN, but also receive registration information sent from a host through the CER, and store or update mapping relations between a host ID host identifier (HI) and the CER ID and between the HI and host location information. A method for registering host information includes the steps as follows. The host acquires routable host location information in an EN to which the host currently added and information of the CER in the EN. The host sends registration information to the CN through the CER in the EN. Further, a method for sending data is described. The network architecture and methods of the present invention may improve update and query efficiency of the registration information from the host.

主权项

1. A multi-address space mobile network system, comprising:
a core network (CN) and edge networks (ENs), wherein the CN and the ENs are configured to adopt independent address spaces, and each EN is connected to the CN through a core edge router (CER); wherein a Domain Name Server (DNS) is configured to be set in the CN and is configured to store a first mapping relationship between a host name and a host identifier (HI); wherein the CN comprises a tangible non-transient computer-readable medium, including a distributed hash table (DHT) set in the computer-readable medium, and the DHT includes computer-executable instructions for:
receiving registration information sent by a host through the CER,storing or updating a second mapping relationship between the HI and a CER identifier (ID),storing or updating a third mapping relationship between the HI and host location information, andstoring or updating a fourth mapping relationship between the CER ID and CER location information in the CN; wherein the CER comprises a tangible non-transient computer-readable medium, the computer readable medium including computer-executable instructions for: advertising the EN connected to the CER of a default route reaching the CN; forwarding the registration information from the host to the DHT; and receiving a query message from the host, querying in the DHT according to the query message, and returning a query result to the corresponding host; wherein the first mapping relationship is absent from the DHT; and wherein the second mapping relationship, the third mapping relationship, and the fourth mapping relationship are absent from the DNS.
