主动网络管理代理的执行环境

随着网络的迅速发展，网络管理变得越来越复杂，主动网络以其动态特性为网络管理带来了新的挑战和新的契机，根据主动网络的特性设计了一个主动网络管理代理的执行环境（ANMAEE），该环境支持主动网络管理代理的URL部署和字节码部署，并提供两级安全结构，代码的合法性验证和基于角色的安全加载，管理接口共享动态库机制提供了动态被管对象和管理代理间交互，为管理主动节点上其它执行环境及主动网络服务提供了一种有效的手段。利用主动网络管理代理执行环境可以实现主动网络管理代理的动态部署，改善网络管理的可扩展性，该主动网络管理代理执行环境（ANMAEE）已经在Linux平台上实现。

ACTIVE NETWORK MANAGEMENT AGENT EXECUTION ENVIRONMENT

With the rapid development of network, network management becomes more and more complex. Dynamic programmability of active networks introduces new difficulty to the task of network management. But on the other hand, it also opens a new opportunity in network management. Based on the programmability of active networks, an active network management agent execution environment (ANMAEE) is presented. ANMAEE supports two approaches for deploying active network management agents: URL-based approach and byte code-based approach. For security, ANMAEE provides a two-level security mechanism,that is, authentication for byte code and role-based secure loading. The shared library for management interface provides the interaction between manageable dynamic objects and the management agent, and serves as an effective way for managing other execution environments and active network services on the active node. Dynamic deployment of the active network management agents is achieved by the ANMAEE, improving extensibility of the network management. The prototype of ANMAEE has been implemented on the Linux operating system.
