System for real traffic replay over wireless networks

摘要

A real traffic replay over wireless networks with environment emulation and an event-driven automata-synchronized replay method are disclosed. The system includes a first traffic capture module configured to capture packet traces and environment effects in a real environment, a first event transform module configured to transform the packet traces into a sequence of events, and a reproduce module configured to receive the environment effects from the first traffic capture module and the sequence of events from the first event transform module such as to control a replay of the environment effects in the real environment and the sequence of events coordinately by means of automata.

1. A system for real traffic replay in wireless networks, comprising:
a first traffic capture module configured to capture packet traces and environment effects in a real environment and export the packet traces and the environment effects, wherein the first traffic capture module includes a plurality of monitors deposed in the real environment to record the packet traces; a first event transform module configured to receive the packet traces from the first traffic capture module, transform the packet traces into a sequence of events, and export the sequence of events; a reproduce module configured to receive the environment effects from the first traffic capture module and the sequence of events from the first event transform module so as to control a replay of the environment effects in the real environment with the sequence of events coordinately by means of automata; and a ratio calculation module configured to receive the sequence of events from the first event transform module and compare the sequence of events and a sequence of replayed events so as to calculate a reproduction ratio.
