摘要： An Internet Protocol (IP)-based network incorporates an application level switching server and a number of packet endpoints. A packet endpoint multiplexes application sessions destined for different packet endpoints into one multiplexed session that is terminated with the application level switching server. The latter extracts each application session (or packets associated therewith) and repackages, or switches, them into other multiplexed sessions such that at least two switched packets are transmitted to different packet endpoints. The multiplexed sessions utilize either RTP/UDP/IP or UDP/IP encapsulation.

摘要： The specification relates to a device and method utilized for packaging voice data (and other delay critical ‘connection’ or ‘flow’ type application data) for point-to-point transport from one Packet Circuit Gateway (PCG) to a second PCG over Label Switching Routers (LSRs) within an Internet Protocol (IP) network; the beneficial aspects of the packaging format being: (i) a reduced overhead requirement when compared to conventional IP telephony due to inclusion of a switching label in lieu of an appended IP header, thereby increasing network bandwidth efficiency, and (ii) the increased transport speed associated with layer two label switching when compared to layer three forwarding.

摘要： A quality of service guarantee for voice and other delay sensitive transmissions within an Internet Protocol (IP) network is provided by identifying the IP network path utilized for IP packet transmission between source and destination edge devices and virtually provisioning IP network path bandwidth for priority voice traffic. Priority for voice packets and admission control of new voice calls (and other delay sensitive traffic) based on the remaining available capacity over the IP network path guarantees that high priority voice (and other delay sensitive traffic) meet stringent delay requirements. A Virtual Provisioning Server is utilized to maintain bandwidth capacity data for each path segment within the IP network and to forward the bandwidth capacity data to a Signaling Gateway. The Signaling Gateway determines whether to accept or reject an additional delay sensitive traffic component based upon available bandwidth capacity for an IP network path. The Signaling Gateway then signals the originating source edge device as to its determination to accept or reject. Quality of Service guarantees concerning acceptable delay and jitter characteristics for real-time transmission over an IP network are therefore provided without the need to directly signal the individual IP routers over which an IP network path is established.
摘要翻译： 通过识别用于源和目的地边缘设备之间的IP分组传输的IP网络路径，并为优先级语音流量虚拟地提供IP网络路径带宽，来提供因特网协议（IP）网络中的语音和其他延迟敏感传输的服务质量保证 。 基于IP网络路径上的剩余可用容量，语音分组和新语音呼叫（以及其他延迟敏感业务）的优先级保证高优先级语音（和其他延迟敏感业务）满足严格的延迟要求。 虚拟配置服务器用于维护IP网络内每个路径段的带宽容量数据，并将带宽容量数据转发到信令网关。 信令网关基于IP网络路径的可用带宽容量来确定是接受还是拒绝附加的延迟敏感的业务组件。 然后，信令网关就发信源边缘设备向其接受或拒绝的确定信号。 因此，提供了关于通过IP网络进行实时传输的可接受延迟和抖动特性的服务质量保证，而不需要直接通知建立IP网络路径的各个IP路由器。

摘要： A technique for improving optical cross-connections comprises placing a switch in front of a number of processing units. So configured, the units are no longer dedicated to a specific link or signal. When necessary, a unit is connected/disconnected to one or more optical links by the switch to carry out any number of processing functions, such as regeneration, Raman pumping, dispersion equalization/compensation or performance monitoring. Because the units are no longer dedicated to specific links the cost of the cross-connections and the network it is a part of can be reduced.

摘要： Precomputation techniques for determining primary and/or restoration paths in an optical or electrical network. A hybrid centralized/distributed approach is provided in which certain information used in distributed precomputation is downloaded from a central controller of the network. The downloaded information is used as an input to a distributed precomputation algorithm implemented by the network nodes in order to provide improved performance. The central controller makes use of its knowledge of global network topology in computing the information to be downloaded to the nodes. The downloaded information generally represents network information which changes with less frequency than other network information processed by the nodes as part of the distributed precomputation algorithm. The information downloaded from the central controller may include, for example, network connectivity information, capacities for at least a subset of the links in the network, a subset of all possible routes between a source node and a destination node in the network arranged in an appropriate initial search order, a link contention index for each of the links in the network, and indices assigned to one or more of the nodes and links of the network, wherein the indices are used to determine an order of processing operations involving the one or more nodes and links of the network.

摘要： A new protocol layer is provided as part of a protocol stack associated with a packet-based multiaccess mobile communications system. The protocol layer is preferably located above a medium access control (MAC) protocol layer and a physical protocol layer of the system and below a transport/network protocol layer. Such a subnetwork protocol layer provides, inter alia, the communications system with various mobility management functions, for example, tracking mobile user stations throughout the system, mobile station access to the system, and connection/call continuity within the system. The subnetwork protocol layer of the invention also performs packet routing functions associated with the system. Routing can be accomplished in many ways, for example, via source routing, connectionless routing, or tunneling. Further, the new protocol layer of the invention is preferably located above a data link layer with respect to the protocol stack associated with communications between network nodes.
