摘要： A system and method for bandwidth management by controlling the bit rate of a signal stream in real time according to available link bandwidth. Applications include multiple-channel video data streams over a limited-bandwidth link such as a Digital Subscriber Line. A video signal is transrated at the head end to multiple streams having different bit rates, by a multirating device which sends the multiple streams over a network, along with metadata containing information about the data structure and parameters of the streams. At the network access edge, a demultirating device uses the metadata to select the stream with the highest video quality whose bit rate does not exceed the available bandwidth of the end-user's access link. This scheme provides multiple unicast signals to different end-users in place of a single multicast signal, supports multiple high-definition channels over a limited bandwidth link, and is compatible with standard encryption methods.

For example, in one embodiment such means include: means for receiving a packet having identified therein a source Media Access Control (MAC) address and a Virtual Local Area Network (VLAN) Identifier, wherein the VLAN identifier corresponds to a VLAN which is non-existent on a network switch; means for modifying the packet received to include two VLAN tags, a first VLAN tag corresponding to the VLAN identifier identified within the packet received and a second VLAN tag, distinct from the first; means for determining no forwarding database entry exists for the modified packet; and means for creating the VLAN on the network switch to handle received packets tagged with the VLAN identifier.

摘要： A method for field aware virtual connection discovery is described. In an embodiment, a set of virtual connection domains and a set of virtual connection connectors are determined from a network. Each of the virtual connection connectors defines a connection between two or more of the virtual connection domains. An initial virtual connection connector is selected and added to a virtual connection map. A packet is generated which represents the selected virtual connection connector. The packet is flooded through the virtual connection domains and virtual connection connectors. Each virtual connection domain or virtual connection connector which the packet passes through is added to the virtual connection map. After the flooding is complete, the virtual connection map is displayed.

摘要： A system, method, and optical switch for communicating timing. A determination is made whether one of a number of data streams are available. Packets are received at a remote node in response to determining one of the number of data streams is available. A timing characteristic of the at least one of the packets is associated with a tick of a reference clock. The tick of the reference clock is extracted utilizing the timing characteristic of the at least one of the packets. A secondary clock is disciplined with the reference clock by adjusting the secondary clock based on a difference between times measured by the reference clock and the secondary clock to generate a clock signal. The clock signal is communicated to one or more interfaces for distributing.

摘要： Solutions are provided that allow a network device to apply flow control on the MAC layer while taking into account the priority of the frame of traffic. This may be accomplished by generating a frame indicating that traffic flow should be paused, while utilizing a new opcode value, or alternatively by utilizing a new type/length value (possibly combined with a new opcode value). A receiving device may then examine the fields of the frame to determine whether it should use priority-based pausing, and then examine other fields to determine which priority-levels to pause and for how long. This allows for improved efficiency in flow control at the MAC layer. Additionally, the tagged pause frames can be forwarded over multiple hops on Local Area Networks across a Metropolitan Area Network or Wide Area Network.
摘要翻译：提供的解决方案允许网络设备在考虑到流量帧的优先级的情况下对MAC层应用流量控制。这可以通过生成指示业务流应该被暂停，同时利用新的操作码值，或者通过利用新的类型/长度值（可能与新的操作码值组合）来实现。然后，接收设备可以检查帧的字段以确定它是否应该使用基于优先级的暂停，然后检查其他字段以确定要暂停的优先级等级以及多长时间。这样可以提高MAC层的流量控制效率。此外，标记的暂停帧可以通过城域网或广域网在局域网上的多跳进行转发。

摘要： A topology aware system that facilitates activation of a new service in a dynamic network is provided. The system automatically determines changes in network topology and provides current topology information to determine an optimal service activation path for the new service. The optimal service path is determined by combination of shortest path using standardized algorithms over discovered adjacencies, logical roles assigned to devices and a service-hub for a particular UNI. The service hub is discovered automatically by employing current topology information determined by the system itself. Thus, the system can activate a new service to a dynamic network without any manual topology feed.
