在分析典型的現(xiàn)有主動網系統(tǒng)的基礎上，借鑒Protocol Booster的設計思路，提出了一種新的面向實用網絡環(huán)境的主動網執(zhí)行環(huán)境模型。該模型在充分考慮性能(包處理效率)的基礎上，采用類似Protocol Booster的增量實現(xiàn)方法，易于擴展并且與現(xiàn)有網絡完全兼容，并給出了在Linux平臺下該模型的實現(xiàn)。

Abstract In this paper, the experimental active networks execution environments are analyzed and a novel execution environment model is given, which aims at the practicability in nowaday networks(Internet). This execution environment model uses a protocol-booster-like increment, which is easy to be extended and completely compatible with nowaday networks. At last, based on Linux operation system, an implementation frame of this execution environment model is given.
