分析了第一代主動網(wǎng)在數(shù)據(jù)包處理中存在的不足，引入新的主動節(jié)點(diǎn)數(shù)據(jù)流調(diào)度模型A-Flow，給出了該模型在主動節(jié)點(diǎn)傳輸系統(tǒng)ANTS中的實(shí)現(xiàn)方案。新模型基于主動網(wǎng)封裝協(xié)議ANEP，通過分解調(diào)度輸入主動節(jié)點(diǎn)的數(shù)據(jù)流，可以實(shí)現(xiàn)不同的執(zhí)行環(huán)境在同一節(jié)點(diǎn)共存。該模型擁有數(shù)據(jù)包緩存、認(rèn)證及凈荷調(diào)度等功能，提高了主動節(jié)點(diǎn)的性能和安全性。

Abstract This paper analyses the deficiency of packet handling in active networks, and presents A Flow-dispatching model named A-Flow on active networks. In this paper a project of ANTS over A-Flow is implemented. The new model is based on ANEP, it can make multiple execution environments interoperate on the same node, and it has functions of packet buffering, identification and payload dispatching, which may improve the performance and security of active nodes.
Key words active network; flow dispatching; performance; interoperation; A-Flow
