目前的网络体系结构缺乏一定的灵活性,制约了新协议、新应用的开发。主动网络把计算能力从端结点引入到网络内部,赋与网络可编程能力。伴随着网络灵活性的提高,网络管理的难度也在增加,利用移动代理来改善主动网络管理是一个有效的途径。 The current network architecture lacks some flexibility and restricts the development of new protocols and new applications. Active network to the computing power from the end node into the network, endowed with network programming ability. With the improvement of network flexibility, the difficulty of network management is also increasing. It is an effective way to improve active network management by using mobile agents.
