“…Furthermore, Akkus et al improve this approach at a certain degree in the literature [4]. Zhang et al propose another similar scheme to reduce delay or packet loss, which is deployed in multi-channel media delivery [5]. They find a PLR (Packet Loss Rate) matrix for multichannel delivery paths, which can help to locate exactly the links resulting in network congestion.…”

“…There are several application layer strategies for multi-channel content dissemination in existing literature [3][4][5][6]. Akkus et al mainly adopt a chain-topology overlay to disseminate multi-channel media streams considering lack of network bandwidth and use layered video coding to reduce communication traffic to satisfy the network capacity at the expense of multimedia presentation quality [3].…”

Recently multi-channel multimedia broadcast systems on P2P network have emerged in applications such as long-distance education and multimedia broadcast television. With the conflict between huge amounts of streaming data and limited available bandwidth over the Internet seemingly irreconcilable, we observe 1) some channels demand disseminating rapidly, having no requirement for high presentation quality at receivers and 2) some channels expect better quality of service metrics such as bit rate and delay than others while bandwidth contention of multiple channels makes it difficult to realize. Existing proposals have not done enough work based on the two observations. In this paper, we propose DiffStream, a multi-channel dissemination strategy. In DiffStream, each channel disseminates partial streaming data instead of all, using MDC technology. Meanwhile, service differentiation is also achieved by treating different channels with varying priorities and regulating allocation of network resource to different channels in application layer. Furthermore, an extensive mechanism of vacant bandwidth preemption for improving bandwidth utilization is also raised. Experiments are constructed on NS2 and the results have demonstrated DiffStream's effectiveness in achieving our design objectives.

A computer network is basically the combination of computers and different type of devices that are interfaced by a range of resources i.e. communications channels that provide the communications between users and allow them ability of sharing the resources. Multicasting is used to send the information from one receiver to group of receivers. But it is faced big issue because of additional data demand of receivers which may cause of congestion. There are different approach to control congestion i.e. single rate and multi rate approach. We are considering the single rate approach. TCP friendly multicast congestion control technique (TFMCC) is basically a first single rate multicast congestion control technique. It uses the steady state equation to adjust the throughput. But this mechanism has the problem of feedback implosion. It creates the congestion at the source side. This problem was solved by pragmatic general multicast congestion control (PGMCC) approach. In this paper, we provide an effective mechanism for multicast congestion control which work based on utilization of situation and improve the solution with respect to TFMCC, PGMCC.

“…The other mechanism uses the Fuzzy-logic-based Rate Adaption (FRA) Scheme for TFMCC to control the congestion in order to enhance the smoothness of TFMCC. In order to alleviate oscillations of sending rate for TFMCC sender, FRA introduces five actions for adjusting rate [9][10][11].…”

Networking is the important part of the computer networks. Multicasting is also one of the essential areas of networking. In multicasting, sender can send information or data to the group of end receivers in a single transmission. It is a big issue because of more data demands of receivers which cause the congestion. Multicast is one of the crucial method to avoid congestion and make network perform stably. In this paper, we propose, link utilization algorithm to deal with multicast congestion control. We propose the equation to improve the utilization of the channel or link. The simulation results show that proposed work provide the better throughput of the network with respect to sending rate, queue size, packet loss ratio and time.
