Partial versus Early Packet Video Discard

چکیده
In this paper, we propose and compare two video slicebased discard schemes, namely adaptive-PSD and Adaptive-ESD, for the transmission of MPEG video streams overATM best effort services. The schemes perform adaptive and selective cell burst discard at the level of MPEG video slices and intelligently adjusts drop policies to switch buffer occupancy and video cell payload types. In comparison to previous approaches, the performance evaluation have shown a significant reduction of the bad throughput crossing the network and a better protection of critical Intraand Predictive-coded pictures at both cell and video slice levels.

Performance of Selective Packet Dropping Schemes in Multi-hop Networks
Networked applications require good performance from the network along with a high level of predictability. One of the factors that affects application performance is the packet dropping policy adopted in the switch or router. In this paper, we evaluate the absolute performance of various packet dropping policies, and also the predictability they can provide to an application. The packet droppi...
متن کاملQuality of Service and Performance Evaluation of Congestion Control for Multimedia Networking
The most important components of multimedia networking are video streaming and synchronization. In video networking, the frames are split into smaller packets at the application layer. The packets of a frame are assembled before being processed at the receiver. For realtime video streaming, packet acknowledgments and retransmission are not practical. When congestion occurs, some packets may be ...
متن کاملPerformance of Selective Packet Dropping Policies in Heterogeneous Networks
| The performance analyses of selective packet dropping policies have usually been performed using homogeneous traac sources and under one node scenarios. In this paper we focus our attention not only to heterogeneous sources but also heterogeneous environments. We present simulation results of application level performance for heterogeneous traac sources under three diierent packet dropping sc...
متن کاملEarly Selective Packet Discard for Alternating Resource Access of TCP over ATM-UBR
We investigate packet discarding schemes for TCP over ATM with UBR service. In doing so, we tested the e ective throughput of two existing schemes, Partial Packet Discard(PPD) and Early Packet Discard(EPD), as compared to the Random Cell Discard(RCD) scheme which discards any incoming cells after bu er over ow. We observed that PPD alleviates the e ect of packet fragmentation so that it gets e ...
متن کاملOn the Effectiveness of the Longest-Packet-In Selective Packet Discarding Policy
In this paper, we introduce a novel packet discarding policy called Longest-Packet-In (LPI) which maximizes the cell goodput, the ratio of outgoing good cells to the total number of cells that arrive at a queue. We compare LPI to: Tail Drop, Early Packet Discard, Early Packet Discard with Hysteresis and Fair Early Packet Discard with Hysteresis by investigating the trade-off between maximizing ...
