چکیده
Video on Demand applications emerge on campus wide networks Compressed video streams pass switches which do not have any bandwidth reservation mech anism nor any other mechanism against congestion The switches shared among video servers WWW servers and clients get easily congested in critical sit uations hence the switches drop packets and the qual ity of end to end delivery service degrades To provide soft bandwidth QoS guarantees for video we designed and tested through simulation a dynamic end to end multi path protocol for video tra c We compared our dynamic multi path protocol per formance with a dynamic single path protocol and the experiments show signi cant advantages of the dynamic multi path communication with respect to provision of soft bandwidth guarantees for video tra c A disadvan tage of our approach is the reordering overhead How ever the use of the higher level frame information helps to simplify reordering and the overhead is acceptable

Dynamic Multi-path Communication for Video Traac
Video-on-Demand applications emerge on campus-wide networks. Compressed video streams pass switches which do not have any bandwidth reservation mechanism , nor any other mechanism against congestion. The switches, shared among video servers, WWW servers and clients, get easily congested in critical situations , hence the switches drop packets and the quality of end-to-end delivery service degra...
متن کاملThe Feedback Based Mechanism for Video Streaming Over Multipath Ad Hoc Networks
Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...
متن کاملA Machine Vision Based Surveillance System For California Roads
Automatic symbolic tra c scene analysis is essential to many areas of IVHS (Intelligent Vehicle Highway Systems). Tra c scene information can be used to optimize tra c ow during busy periods, identify stalled vehicles and accidents, and aid the decision-making of an autonomous vehicle controller. Improvements in technologies for machine vision-based surveillance and high-level symbolic reasonin...
متن کاملMultiservice Traffic Allocation in Leo Satellite Communications
Satellite communication promises potential methods for providing global communication. In particular, by the development of a Low Earth Orbital (LEO) satellite constellation, both global coverage and broadband communication will be accessible. Problems arise in situations where various tra¢ c types in broadband communication require di¤erent levels of quality of service (QoS). Tra¢ c control is...
