Abstract:

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 of the algorithm proved that the performance of the algorithm is superior to the traditional buffer control algorithms in existing real-time service.
