A Tool for Automated Analysis of Network Software Latency
|
Abstract:
The complexity and the dynamic executing behavior of network software add to the difficulties for identifying the precise causes of latency. Using performance monitoring functions provided by the advanced microprocessor and implementation characteristics of network software, NetSlice provides a novel, modular, and extensible way for automated analysis of network software latency. The architecture of NetSlice and its components are introduced at first. Then the performance of NetSlice is studied in detail and the typical application strategy is also given.To demonstrate the utility of NetSlice,the results of analyzing the latency of TCP sending process on linux operating system are presented.The experimental results show NetSilce can shed considerable light on the causes of latency in network software
