Video server sends a RSVP message to reserve resource for client, and the system calculates and analyses QoS parameters using control information of RTP/RTCP packets and ICMP Echo request message, and controls the transmission grade by corresponding strategy to ensure network QoS, which enhances the system reaction to network condition and stabilizes the throughput and solves the problems of data transmission and using bandwidth fairly between multicast data and other kind of data when network is congestible and unstable.

整个模型系统主要由视频服务器、路由节点和客户端构成，通过RSVP协议进行资源预留协商，并在传输过程中利用RTP/RTCP包中携带的控制信息结合ICMP Echo请求报文提取QoS参数，对其进行分析判断，采用相应策略对传输级别进行实时控制，保障了网络QoS，提高了系统对网络状况的反应速度，降低了传输速率的波动性，较好解决了网络拥塞和不稳定时数据的有效传输以及与其他数据流公平占用带宽的问题。

Retroreflector array is used as pseudo phase conjugator in the system. The fidelity of the conjugate wave and matching problem of the retroreflector array and Hartmann-Shack wavefront sensor is discussed. Several data fusion methods are presented in order to having two Hartmann-Shack wavefront sensors control one set of wavefront corrector. The misalignment errors of Hartmann-Shack wavefront sensor and arrangement errors of wavefront sensor and deformable mirror are analyzed. At the same time, numerical work based on the data of practically system, such as 61 element AO system, are done corresponding to the problem respectively and the results are given. The system of CP/CM AO is setup to fulfill all the functions. Through the data fusion of two Hartmann-Shack wavefront sensors, the system runs successfully and realizes the close loop. It lays a good foundation for the application of CP/CM AO. Another aspect of this paper is to expand the working band of Hartmann-Shack wavefront sensor through Frequency Transfer of Nonlinear Optics.
