Most ISPs and telecom carreers test reacheability to their nodes and interfaces by SNMP or ICMP echo. But it takes a long time to test for ten thousands of nodes by traditional techniques. Furthermore, huge amount of short packets occupy capacity of links and the packets can interfere the other flows. At this time, test software using traditional techniques can not distinguish whether the reason of packet loss is unreachability or congestion.
We should use congestion detection method and congestion control method when we make tests of node reacheability. The congestion control algorithm of TCP is well-known but the algorithm has some problems. Firstly, bandwidth is extremely narrowed in certain conditions. Secondly, the algorithem is not concerned in one-to-multi connections but one-to-one connections. In order to solve this problem, it is necessary to invent the methods to send many packets and to adjust transmission rate. Using an output of this system, ISP and telecom carrer operators will get reliable results. In this paper, we report the method and the experiment result of this system. |
