摘要： Techniques are provided herein to add multicast media streams to teleconferencing sessions without the unwanted side effects that occur when a speaker's own media is echoed back to the speaker. Multicast and unicast media streams are generated by a network device, e.g., a conference bridge, and distributed to any number of endpoints, e.g., conference endpoints. A media selector is provided that selects the appropriate multicast or unicast media stream for forwarding to an associated network endpoint.

摘要： In an example embodiment disclosed herein, Wide Area Network optimization modules coupled to peers are configured to maintain peer routing tables. The peer routing table (PRT) is used by the Wide Area Network optimization module to determine the peer for a given destination, such as an Internet Protocol “IP” destination. Each peer is responsible for advertising to other peers which networks the peer is able to reach. This information is advertised when a tunnel is first created and subsequently whenever necessary. Initially, a peer sends out a list of entries corresponding to its directly connected networks, with the exception of the network connected to the interface on which the peer is advertising (e.g. the network used for the tunnel). This enables other peers on the network to populate their PRT entries.

摘要： Described herein is a flow control scheme suitably adaptable to Transmission Control Protocol (TCP) and Stream Control Transmission Protocol (SCTP). In an example embodiment, the guaranteed and maximum allowable bandwidths are employed to determine the size of the congestion window. For example, the flow congestion window size starts proportional to the guaranteed bandwidth and increases until reaching the maximum allowable bandwidth. In particular embodiments, a fixed value is used for determining how fast the congestion window increases. For example the congestion window may increase exponentially while the current size of the congestion window is at or below a fixed value, and increase linearly when the current size of the congestion window is above the fixed value. In an example embodiment, the fixed value does not change even if a collision is detected and the current amount of unacknowledged data allowed is reset to an initial value.
摘要翻译： 这里描述了适合于传输控制协议（TCP）和流控制传输协议（SCTP）的流控制方案。 在示例实施例中，采用保证和最大允许带宽来确定拥塞窗口的大小。 例如，流量拥塞窗口大小与保证带宽成比例，并增加直到达到最大允许带宽。 在特定实施例中，使用固定值来确定拥塞窗口增加的速度。 例如，拥塞窗口可以指数增加，而拥塞窗口的当前大小等于或小于固定值，并且当拥塞窗口的当前大小高于固定值时线性增加。 在示例实施例中，即使检测到冲突并且允许的当前未确认数据量被重置为初始值，固定值也不改变。

摘要： Flows of packets are dynamically mapped to resource queues. Flows of packets are received at a network device to be routed from the network device in a network. Each flow comprises packets to be sent from a source to a connection. Data is stored for a queue allocation table that maintains a plurality of buckets to which received packets for a flow are assigned and indicating which of a plurality of resource queues are allocated for respective buckets. For each packet in a flow, a hash function is computed from values in a header of the packet and the packet is assigned to one of the plurality of buckets based on the computed hash function. One of a plurality of resource queues is allocated for each bucket to which packets are assigned based on the computed hash function.

摘要： A method for generating an accurate adaptive clock is disclosed. The method includes accessing data at a first clock rate, generating an adaptive clock that has an adaptive clock rate that is based on the arrival rate of said data, accessing data related to the first clock rate and the adaptive clock rate. The adaptive clock rate is adjusted based on a determined relationship between the first clock rate and the, adaptive clock rate.
