Topology probing method for mobile IP system
First Claim
1. A topology probing method for a mobile IP system having a probing server and a network system, the network system having a client and a home agent corresponding to the client, the method comprising the steps of:
- (A) the probing server sending plural times of probing requests to the remote network system;
(B) when receiving the probing requests, the client of the remote network system directly responding current resource allocation information to the probing server;
(C) the probing server constructing a network location topology of the client is in the network system by the current resource allocation information returned from the client; and
(D) the probing server performing a dynamic prediction process based on several previous current resource allocation information returned from the client for calculating a time interval between sending the current probing request and sending the next probing request, thereby decreasing the number of sending the probing request.

Abstract
A topology probing method for mobile IP system is disclosed, which has a probing server, multiple clients, and multiple home agents corresponding to the clients. When the probing server sends a probing request to the client in a remote network, the client responds current resource allocation information to the probing server. The probing server establishes the network topology of the clients based on the current resource allocation information. The probing server performs a dynamic prediction based on several previous responding statuses for calculating a time interval between sending the current probing request and sending the next probing request, thereby decreasing the number of sending the probing request.

7. A topology probing method for a mobile IP system having a probing server, a client, and a home agent corresponding to the client, the method comprising the steps of:
-
(A) the client actively providing current resource allocation information to the home agent of the client;
(B) the home agent of the client further forwarding the current resource allocation information to the probing server; and
(C) the probing server computing a network location of the client and constructs a network topology of the client by the current resource allocation information returned from the home agent of the client. - View Dependent Claims (8)
