Abstract

As networks have spread, various services such as video streaming and IP telephone have been achieved. Along with that, complexity of networks has advanced, but there have not been a way to manage all packets distributed on networks, and thus quality guarantee and reliability securement have been problematic. Also, an increase in cost such as recovery solution upon a failure has been a big problem. Accordingly, an IP probe which detects packets distributed on communication paths in real time and visualizing a status of the network is achieved by a heterogeneous multi-core processor including a dynamic reconfigurable processor. By changing configuration function in a packet analysis depending on characteristics of the packets, low power and high performance are achieved with flexibly handling various standards and services. Also, by allocating a plurality of nodes, a status of the whole network is visualized. In this manner, a low-power and small IP probe node is achieved, and, by arranging a plurality of the IP probe nodes on a network, movements of packets distributed on the network, which have been impossible to be observed, can be grasped in real time, and thus an improvement in network quality and a reduction in maintenance management cost are achieved.
