An adaptive and selective cell drop policy with dynamic data partitioning for best effort video over ATM
In this paper, we propose and evaluate a new MPEGbased video delivery framework for use with ATM best effort services (e.g. Available Bit Rate and Unspecified Bit Rate). The presented framework relies on three components : a video-oriented cell discarding scheme, which adaptively and selectively adjusts drop level to switch buffer occupancy and video cell payload types; a dynamic frame-level pr...
متن کاملGFR - A NEW SERVICE CATEGORY TO SUPPORT TCP TRAFFIC OVER ATM K.Jayanthi, G.Florence Sudha and P.Dananjayan
The TCP/IP protocol is the standard requirement for all applications that need to communicate over the Internet. Guaranteed Frame Rate GFR, a recently approved service category by ATM Forum is best suited to efficiently support TCP/IP Traffic in ATM networks. GFR is proposed to overcome the performance degradation problems faced by TCP/IP Applications over ATM. It is intended to provide minimum...
متن کاملPerformance analysis of cell discarding techniques for best effort video communications over ATM networks
With increasing interest in the transmission of audio-visual applications over ATM best effort services, efficient videooriented control mechanisms for improving the video quality in the presence of loss have to be designed. In this paper, we propose and evaluate two new slice-based discard schemes for use with Available Bit Rate and Guaranteed Frame Rate services (e.g. formerly UBR+). The sche...
متن کاملTCP / IP over ATM - GFR *
Today ATM technology is facing challenges from Integrated Service IP, IP switching, Gigabit IP router and Gigabit Ethernet. Although ATM is approved by ITUT as the standard technology in B-ISDN, its survivability is still in question. Since ATM-UBR (Unspecified Bit Rate) provides no service guarantee and ATM-ABR (Available Bit Rate) is still unattainable for most users, many existing users have...

Today ATM technology is facing challenges from Integrated Service IP, IP switching, Gigabit IP router and Gigabit Ethernet. Although ATM is approved by ITU-T as the standard technology in B-ISDN, its survivability is still in question. Since ATMUBR (Unspeci ed Bit Rate) provides no service guarantee and ATM-ABR (Available Bit Rate) is still unattainable for most users, many existing users have ...
