This paper presents a new overlay-based congestion management mechanism that provides the proportional fairness among competing aggregates and the improvement in packet loss ratio for Differentiated Services (DiffServ) network. In the proposed scheme, a QoS control packet is sent from the ingress to the egress router every fixed time interval. The ingress router employs a simple additive increa...

In this paper, we propose a new packet loss control mechanism – Dynamic Partial Buffer Sharing scheme. With DPBS scheme, the thresholds are dynamically adjusted in run-time based on packet loss behavior. So that DPBS scheme avoids parameter-setting problem, and it can achieve desired relative packet loss ratio easily. In addition, DPBS scheme can achieve higher buffer utilization for its adapta...

The article tackles the problem of quality of service assurance in photonic networks. The idea of multi-service photonic network model with the coexistence of optical circuit and packet switching mechanisms and cell communication is used as a basis for service differentiation in the optical domain. Cell loss ratio as a key performance indicator determines the required optical switching mechanis...

Modern control systems widely use network to decrease the implementation cost and also increase the performance. Although they have several advantages, they suffer from some limitations and deficiencies. Packet loss is one of the main limitations which affect the control system in different conditions and finally can lead to system instability. To prevent such problems it is important to model ...

The Networked Control System in modern control widely uses to decrease the implementation cost and increasing the performance. NCS in addition to its advantages is inevitable. Nevertheless they suffer of some limitations and deficiencies. Packet loss is one of the main limitations which affect the control system in different conditions and finally may lead to system instability. For this reason...

Network coding in Mobile Ad hoc Network (MANET) is well-known in reducing delay, increasing throughput, and improving transmission reliability. While the data throughput capacity of MANETs is unknown, the scaling of capacity with the number of nodes has recently received increasing attention. This paper proposes a Complex Field Network Coding-based Multipath Routing in MANETs (CFNC-MRM). The pe...

VLBI is gradually moving to the point where Gbps data rates are becoming routine. A number of experiments have shown that the internet can be used at data rates of several hundred Mbps on production networks. However use of the network is accompanied by packet loss. The paper discusses the statistics of packet loss as found by recent tests and investigates the expected effect of packet loss on ...

We proposed and evaluated a speech packet loss concealment method which predicts lost segments from speech included in packets either before, or both before and after the lost packet. The lost segments are predicted recursively by using linear prediction both in the forward direction from the packet preceding the loss, and in the backward direction from the packet succeeding the lost segment. P...
