    摘要： A supervisory communications node monitors and controls communications with a plurality of remote devices throughout a widely distributed network. A method, system, and computer program product are provided to convey and maintain information used to synchronize the packetization and burst operations within the network. During session setup, jitter constraints indirectly are used to explicitly communicate a synchronization timing reference. The timing reference is set at the beginning of a phase/period boundary used to service the session. In an embodiment, the announcement of the first grant is used as an explicit indication of the synchronization timing reference value. In another embodiment, the synchronization timing reference value is inferred if a remote device receives contiguous voice grants meeting certain conditions. In an embodiment implementing periodic scheduling, the actual arrival of the first grant is used to infer the synchronization timing reference value. In an embodiment, the present invention enables the synchronization timing reference value and/or the periodicity to be modified if network conditions indicate that packetization and burst operations are out-of-synchronization,

    摘要： There are many circumstances in which delay sensitive traffic and a delay insensitive traffic share an access to a telecommunications network. TCP/IP is well suited for proper delivery of the delay insensitive traffic whereas the delay sensitive traffic uses UDP/IP protocol. When a delay sensitive traffic in UDP/IP packets is in progress, ACK delay parameter in TCP/IP protocol can be adjusted so that UDP packets can be inserted among TCP packets to reduce collision and end-to-end delay of UDP packets.

    摘要： This invention presents a framework for achieving dynamic End-to-End QoS-negotiation and control coordination, with distributed multimedia applications. The framework builds upon dynamic capability negotiation and specification of Adaptation Paths and (alternative) QoS Contracts, based on user preferences. In particular we present a protocol providing End-to-End negotiation of alternative QoS, capabilities, and preferences/configurations, based on extensions of IP-based protocols like SIP/RTSP/SDP, in coordination with mechanisms for network resource reservation (e.g. RSVP), local terminal resource (e.g. CPU, memory, power, auxiliary devices) reservation, and adaptation mechanisms. To this extent, and with respect to two or more peers (101, 103) this invention identifies six phases, through which said peers can establish multiparty, multi-stream, multimedia communications. In detail, the phases are: Protocol Discovery (104), Pre-Negotiation (106), Multi-Stream QoS Synchronization and QoS Correlation (107), Fast-Negotiation (obeying the Economy Principle) (108), Re-Negotiation (obeying the Economy Principle) (109), Resource Reservation Release (110). All the six phases can be concatenated, or be executed at different times.
    This invention also presents the concept of the E2ENP Broker (105), an optional third-party entity, which can be used for relieving peers (101, 103) from performing the time- and resource-consuming Pre-Negotiation phase (106) (and eventually also the Multi-Stream QoS Synchronization and QoS Correlation (107)). This entity may coincide with e.g. audio-/videoconference bridges.
