Holonic Optical Integrated Network Configuration for Multimedia Communications

为了满足未来通信网络的需求，需要超大容量的信息传送网和高度智能化的网络能力。本课题提出了一种新的网络体系结构--Holonic网络，该网络采用分布式协作组网原理，具有自主路由的特点，由两个不同的功能平面组成，除了网络的入口外，没有其他功能平面通过网络进行交互。一种是工作在全光模式下的光传送网（OTN）平面，其中的子光节点（HTN）通过超大容量光链路互连。另一种是以电子处理方式工作的个人导航网（PNN）平面，它作为应用平面构建在高级智能网的业务控制平台上，每个子光节点在不受电子PNN节点直接控制的情况下自主路由。PNN通过引入自治的OTN，从网络资源管理中解放出来，可以集中精力进行用户业务定制。为方便用户创建服务，引入了个人代理（PA）系统，分配给每个用户。PA是一个面向对象的软件模块，充当用户。PNN是PA在网络中搜索用户所需信息的平台。网络管理器（NM）和网络地图（NP）安装在终端侧的位置，作为信息提供商等服务器之一。NP是关于网络资源状态的数据库，例如网络配置、其忙碌/空闲状态、其使用等。NM执行路由生成和网络维护功能。由NM生成的路由信息被发送到对应的HTN并存储在其路由表中。用户信息通过添加连接标识符进行划分和组装成传输信元格式后，发送到OTN，并根据每个HTN中的路由表进行自主交换。

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.
