摘要： VoIP traffic bandwidth through a router port is controlled so that it does not exceed a predetermined bandwidth to ensure a desired quality of service for all VoIP calls routed through the port. Information of a packet received by the port is extracted from a packet header. The information includes source and destination addresses and port numbers as well as the bandwidth used by the packet. If the packet is from an existing call, the packet is routed and the time the packet was received is updated. If the packet is from a new call, it is determined whether the port has sufficient bandwidth to route the new call. If the port has sufficient bandwidth, the packet is routed, bandwidth is allotted for subsequent packets from the new call, and the port information is updated to accept the subsequent packets. If the port does not have sufficient bandwidth, the packet is dropped.

摘要翻译： 控制通过路由器端口的VoIP业务带宽，使得其不超过预定带宽，以确保通过端口路由的所有VoIP呼叫的期望服务质量。 从分组报头提取端口接收的分组的信息。 该信息包括源和目的地址和端口号以及数据包使用的带宽。 如果分组来自现有呼叫，则分组被路由并且更新分组的时间。 如果分组来自新呼叫，则确定端口是否具有足够的带宽来路由新呼叫。 如果端口具有足够的带宽，则分组被路由，为来自新呼叫的后续分组分配带宽，并更新端口信息以接受后续分组。 如果端口没有足够的带宽，则丢弃该数据包。

摘要： A system and method of delivering video content is disclosed. In a particular embodiment, the method includes receiving channel selection data from a set-top box device via an Internet Protocol Television (IPTV) access network. The channel selection data indicates a selection of an IPTV channel. The method also includes sending a rapid channel change (RCC) request to a distribution switch/router system via a subscriber virtual local area network (VLAN) associated with the set-top box device after receiving the channel selection data. The RCC request indicates the selected IPTV channel.

摘要： A method of providing video content includes receiving a channel change data packet from a set-top box device at a subscriber premise via a packet-based video distribution network. The channel change data packet includes data indicating a requested channel and a channel change index value. The method also includes reading the channel change data packet to identify the channel change index value. The channel change index value indicates an available bandwidth at the subscriber premise to receive video content of the requested channel via the packet-based video distribution network. The method also includes allocating an overhead bandwidth to the set-top box device based on the channel change index value.

摘要： A communications system is described for enforcing a service level agreement for a specified customer on a network. The communications system includes a router to receive at least one packet containing data. A management system is in communication with the router, where the management system provides access control commands to the router for the specified customer based upon an agreed upon codec and an agreed upon packet length. A detection system is in communication with the router. The detection system extracts a codec information and a packet length information from the packet. If the codec matches the agreed upon codec and the packet length matches the agreed upon packet length, then the packet is allowed to proceed. Otherwise the packet is dropped from the network.

摘要： A matrixed memory array device is disclosed that includes input ports and output ports. Each input port is coupled to a first data bus and each output port is coupled to a second data bus that is different and separate from the first data bus. A memory brick is placed at each cross-point between first data buses and second data buses so as to switchably couple frames of data from input ports to output ports. Each memory brick contains a plurality of eight transistor (8-T) memory cells that can be used to store, erase, read, write, and switchably couple a data bit from the input port to a corresponding output port.

摘要： A method includes receiving data from a set-top box device at an access system via an access network, the data indicating a selection of a channel at the set-top box device, the data including a multicast group address. The method also includes sending copies of video data packets of the channel from the access system for storage in a first-in first-out cache associated with the channel. The method further includes automatically connecting the set-top box device to a multicast stream of the selected channel after a particular number of video data packets are sent to the set-top box device from the cache. The particular number of video data packets corresponds to a time period between communicating successive random access point packets of the channel and is less than a capacity of the cache.
