Public security system is a special system that should aim at high speed, reliableness and comprehensiveness, fully integrated by video conferencing, data collaboration, multi-channel video surveillance and other operations. As a result, the public security system design must take full account of the industry users' individual character and special function requirements. In this paper, based on the...
In this paper we propose an extension to RSVP protocol, based on dynamic resource reservations, which allows for better coexistence of HD video transmission and elastic traffic (e.g. bulk data transfer). These extensions have been evaluated in two different domains, both in the Quality of Experience (QoE) domain and in the Quality of Service (QoS) domain. Experiments carried out in an emulated multi-node...

It does not make use of any of the standard signaling protocols like session initiation protocol (SIP), session description protocol (SDP), H.323 based protocols, etc. which are generally used for audio...
