Apparatus for the method and characterize the end-to-end path of a packet-based network

摘要

A1 The present invention relates to a method and apparatus characterizing each segment of the network path to the destination host between the source host. A step of collecting data by transmitting and receiving a group of packets are ordered predetermined specific capable size, numbers, and differ in the protocol, the present invention, the source host the packet It is one that is sent from, is addressed to the destination node. Load packets, typically, will expire at the node where a predetermined marker packet is completed in the destination is the movement. After expiry of the load packets, the marker packets provide a means for obtaining information expiration load these packets to allow the characterization of each segment. Further analysis of the collected information, to allow adjustment of the characterization of the packet group, it is possible to characterize the network path of the optimization of the sampling.
