城域以太网电路仿真业务的缓冲控制

在电路仿真业务（CES）中，时延和抖动等参数的控制方法是影响业务质量的关键参数。按照城域以太网论坛（MEF）的标准对CES进行了仿真，提出了对业务质量参数进行控制的策略。参考目前用于话音、多媒体等业务的传统缓冲控制方法，提出了适应于CES的减小时延、平滑抖动的缓冲控制算法，并进行了仿真。结果表明，该算法的性能比现有的实时业务中的传统缓冲控制方法更加优越。

Buffer Control Mechanism for CES over MEN

The control method for the parameters such as delay and jitter is the key factor that affects the quality of circuit emulation service(CES).According to the standards of metro ethernet forum(MEF),the CES was simulated.A strategy was proposed to control the quality parameters of CES.Referenced on traditional buffer control algorithms used in VoIP and multimedia,a new algorithm was proposed to reduce delay and smooth frame jitter.The simulation results proved that the performance of the algorithm is superior to the traditional buffer control algorithms in existing real-time service.
