Holonic Optical Integrated Network Configuration for Multimedia Communications

为了满足未来通信网络的要求，对超大容量的信息传输网络和高度智能化的网络能力提出了更高的要求。本课题提出了一种新的网络体系结构——全息网络（Holonic network），其特点是分布式协同组网原理和自主路由。全息网络由两个不同的功能平面组成，除了入口外，它们之间没有相互作用。一种是全光模式下的光传输网络（OTN）平面，其中全息光节点（HTN）通过超大容量光链路相互连接。另一种是以电子处理方式运行的个人导航网络（PNN）平面，构建为高级智能网络业务控制平台上的应用平面。每个全息光节点在不受电子PNN节点直接控制的情况下进行自主路由。通过引入自治OTN，PNN可以从网络资源管理中解放出来，集中精力进行用户服务定制。为方便用户创建业务，引入个人代理（Personal Agent， PA）系统，分配给每个用户。PA是作为用户的面向对象软件模块。PNN是pa在网络中搜索用户所需信息的平台。nms （Network Manager）和NP （Network Map）作为信息提供者（Information provider）等服务器之一安装在终端侧。NP是关于网络资源状态的数据库，如网络配置、其忙/空闲状态、其使用情况等。nms完成路由生成和网络维护功能。NM产生的路由信息被发送到相应的HTN，并存储在HTN的路由表中。用户信息通过添加connection-ID划分并组装成传输单元格式后，发送到OTN，并根据每个HTN中的路由表进行自主切换。

In order to satisfy the requirements for future communication network, ultra large capacity of information transport network and highly intelligent network capability are required. This project proposed a novel network architecture, named Holonic Network, featured by distributed cooperative networking principle with autonomous routing.Holonic Network is composed of two different functional planes which has no interaction through the network except its entrance. One is optical transport network (OTN) plane operated in the all optical mode, in which holonic optical nodes (HTN) are interconnected by ultra large capacity optical link. Another is personal navigation network (PNN) plane operated in electronic processing mode, which is constructed as application plane on the service control platform of the Advanced Intelligent Network.Each holonic optical node executes autonomous routing without direct control from electronic PNN node. By introducing autonomous OTN,PNN is released from the network resource management and can concentrate to perform user service customization. Personal Agent (PA) system, allocated to each user, is introduced for users to make easier service creation. PA is object oriented software module to act as user. PNN is a platform for PAs to search around tne network for information asked for by user.Network Manager (NM) and Network Map (NP) are installed at the location of terminals side as one of the servers such as the Information Providers. NP is the database on the status of network resources such as network configuration, its busy/idle status, its usage and so on. NM performs the route generation and network maintenance functions. Routing information generated by NM is sent to corresponding HTN and stored in its routing table. After being divided and assembled to transmission cell format by adding connection-ID,user information is sent out to OTN and is autonomously switched according to the routing table in each HTN.
