The Gilbert-Elliott Model for Packet Loss in Real Time Services on the Internet
نویسندگان
چکیده
The estimation of quality for real time services over telecommunication networks requires realistic models in order to generate impairments and failures during transmission. Starting with the classical Gilbert-Elliot model, we derive the second order statistics over arbitrary time scales and fit the parameters to match the packet loss pattern of traffic traces. The results show that simple Markov models are appropriate to capture the observed loss pattern.

In addition, growing bandwidth usage, at one hand, and limit...
متن کاملModeling of Packet Loss and Delay and Their E ect on Real-Time Multimedia Service Quality
Internet packet loss and delay exhibits temporal dependency. If packet n is lost, packet n + 1 is also likely to be lost. It leads to bursty network losses and late losses in real-time multimedia services such as Voice over IP (VoIP). This may degrade perceptual quality and the effectiveness of Forward Error Correction (FEC). To characterize this burstiness, we rst discuss the modeling of packe...

The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...
