摘要： A set of critical nodes or links is identified on the network through which most of the shortest paths on the network occur. Each node compares their distance to end points on the network with a distance between the end points and each of the distinct critical nodes. Where the distance between the end points and the critical nodes is shorter than the distance between the end points and the node, the node is not on the shortest path and does not install forwarding state. Where the distance between the end points and the critical node is larger than or equal to the distance between the end points and the node, the node may be on the shortest path between the pair of end nodes and installs forwarding state. Installation of forwarding state may cause packet duplication, but determining forwarding state is dramatically simplified. The level of duplication may be reduced by selecting a larger number of critical nodes on the network.
摘要翻译：在网络上识别出一组关键节点或链路，通过该关键节点或链路，网络上的大多数最短路径都会发生。每个节点将其距离与网络上的终点进行比较，并在终点与每个不同关键节点之间建立距离。终点与关键节点之间的距离短于端点与节点之间的距离，节点不在最短路径上，不会安装转发状态。在端点和关键节点之间的距离大于或等于端点和节点之间的距离的情况下，节点可以在一对端节点之间的最短路径上，并安装转发状态。转发状态的安装可能会导致数据包复制，但是显着地简化了确定转发状态。可以通过在网络上选择更多的关键节点来减少重复级别。

摘要： A communication system (10) includes a network (12) that is coupled to a number of terminals (22, 24, 26, 28, 30), at least some of which are capable of audio or other forms of real-time interactive data communications over the network (12). Each of the terminals (22, 24, 26, 28 and 30) includes a network adapter that is capable of detecting a collision with another terminal on the network (12). If a collision is detected, transmission of a data frame is aborted, and a backoff time delay is selected. The backoff time delay is selected from a group of delay periods that vary less than exponentially with a number of collisions.
摘要翻译：通信系统（10）包括耦合到多个终端（22,24,26,28,30）的网络（12），其中至少一些能够进行音频或其他形式的实时交互数据通过网络进行通信（12）。每个终端（22,24,26,28和30）包括能够检测与网络（12）上的另一终端的冲突的网络适配器。如果检测到冲突，则中止数据帧的传输，并且选择退避时间延迟。退避时间延迟从一组延迟周期中选择，该组的延迟周期随着碰撞次数的变化小于指数。

摘要： An enhanced communication bridge includes a context interface that enables the audio bridge to learn information about the type of Voice encoder, device, network connection, location, type of call (business vs. personal), identity and position of the individual, and other information about the context of the communication session itself as well as the context of each person joining the communication session. This context information is used to determine how quality of experience targets for the communication as a whole, as well as how each individual contribution should be uniquely processed to attempt to meet the quality of experience targets. Business factors may influence the decision as to the type of processing to be implemented on each of the signals provided by the participants. Corrective action may also be implemented by the bridge on the client network devices as well in the embodiment. The bridge may be centralized or distributed. A video bridge may be implemented as well.
摘要翻译：增强型通信桥包括上下文接口，使得音频桥能够了解关于语音编码器的类型，设备，网络连接，位置，呼叫类型（业务对个人），个体的身份和位置以及其他信息的信息关于通信会话本身的上下文以及加入通信会话的每个人的上下文。这个上下文信息用于确定整个通信的体验质量的质量，以及如何独立处理每个个人的贡献以尝试满足体验目标的质量。业务因素可能影响对参与者提供的每个信号执行的处理类型的决定。在实施例中也可以通过客户端网络设备上的桥来实现纠正动作。桥可以集中或分布。也可以实现视频桥。

摘要： An innovative service modeling framework is provided that can be used to analyze and assess the business opportunities of existing and emerging telecommunication services. This forecasting model/tool provides an approach to assess current and future markets - thus lowering investment risks, ensuring better decisions and subsequently having a greater impact. The core of the framework relies on a novel forecasting model (based on the theory of diffusion or S-curves) that departs from typical models used by popular research firms. The enhanced diffusion model relies on multi-dimensional input parameters and can take into account the impact of disruptions, regulations, network readiness, user utility and other dynamics. The input parameters are modeled as a series of vectors and are used to represent perturbations to the model. These influence the behavior of the adoption rate process in more realistic way.
摘要翻译：提供了一个创新的服务建模框架，可用于分析和评估现有和新兴电信业务的商机。这种预测模型/工具提供了一种评估当前和未来市场的方法，从而降低投资风险，确保更好的决策并产生更大的影响。框架的核心依赖于一种新颖的预测模型（基于扩散理论或S曲线），这种模型偏离了流行研究公司使用的典型模型。增强扩散模型依赖于多维输入参数，可以考虑到中断，法规，网络准备，用户效用等动态的影响。输入参数被建模为一系列向量，并用于表示模型的扰动。这些以更实际的方式影响采用率过程的行为。

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.
摘要翻译：在很多情况下，对延迟敏感的流量和延迟不敏感的流量共享对电信网络的访问。 TCP / IP非常适合延迟敏感流量的正确传输，而延迟敏感流量使用UDP / IP协议。当UDP / IP数据包中的延迟敏感流量正在进行时，TCP / IP协议中的ACK延迟参数可以进行调整，以便可以在TCP数据包之间插入UDP数据包，以减少UDP数据包的冲突和端到端延迟。
