摘要： Packets are encapsulated and sent from a service node to an application node for applying one or more Layer-4 to Layer-7 services to the packets, with service-applied packets being returned to the service node. An identification of a virtual private network (VPN) may be carried within a request packet, encapsulating a particular packet, sent by a service node to an application node for applying a service to the particular packet; with the corresponding response packet sent to the service node including an identification of the VPN for use by the service node node in forwarding the services-applied packet.Additionally, parameters may be included in a request packet to identify a particular service of a general service to be applied to a particular packet encapsulated in the request packet.

摘要： A filtered Forwarding Information Base (FIB) (the “complete local FIB”) is used to determine how to forward packets, typically on line cards. The complete local FIB is generated by filtering (i.e., dropping or removing) extraneous entries in the standard global FIB of a router. This smaller FIB is then installed within the memory of a forwarding engine, possibly implemented as a single application-specific integrated circuit (ASIC), for use in determining how to forward packets, with the router forwarding packets accordingly.

摘要： Advertised routes are associated with a particular tag in a routing database in a second router. A first router subsequently sends one or more messages associated with a route withdraw operation that specifies the particular tag, such that second router can identify, based on the particular tag, a set including multiple routes, and remove those multiple routes from its routing database. For example, the tag may be a Border Gateway Protocol attribute, a Border Gateway Protocol communities attribute, or some other indication, numeric quantity, or opaque value.

摘要： Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with loss of reducing flooding in a bridged network, typically including a device directly connected to multiple upstream bridges. These bridges are configured such that the device receives broadcast/multicast traffic from a single interface of one of the bridges, while allowing unicast traffic over each of the communications links connecting the device to the bridges. In one configuration, the device implements virtual machine(s), each including a virtual network interface associated with a MAC address; and the directly connected bridges are configured, for each particular MAC address of these MAC addresses of the virtual interfaces, such that one and only one of the bridges will forward packets having the particular MAC address as its destination address over a communications link directly connected to the device.

摘要： A hierarchy of schedules propagate minimum guaranteed scheduling rates among scheduling layers in a hierarchical schedule. The minimum guaranteed scheduling rate for a parent schedule entry is typically based on the summation of the minimum guaranteed scheduling rates of its immediate child schedule entries. This propagation of minimum rate scheduling guarantees for a class of traffic can be dynamic (e.g., based on the active traffic for this class of traffic, active services for this class of traffic), or statically configured. One embodiment also includes multiple scheduling lanes for scheduling items, such as, but not limited to packets or indications thereof, such that different categories of traffic (e.g., propagated minimum guaranteed scheduling rate, non-propagated minimum guaranteed scheduling rate, high priority, excess rate, etc.) of scheduled items can be propagated through the hierarchy of schedules accordingly without being blocked behind a lower priority or different type of traffic.

摘要： Disclosed are, inter alia, methods, apparatus, computer-readable media, mechanisms, and means for load balancing manipulation of packet flows within a transport conduit (e.g., a tunnel, pseudo wire, etc.), typically using a load balancing value which is independent of standard routing-based parameters (e.g., source address, destination address, source port, destination port, protocol type, etc.). A load balancing value is included in encapsulated packets transported across a network using a transport conduit. This load balancing value can be used to load balance the individual flows/microflows within the transport conduit.

摘要： In one implementation, a method includes reading first component data from a first tag associated with a first component of a device. The device may be powered on or off. The first component data indicate components associated with the first component at a first time. The method may involve obtaining second component data from a second tag associated with a support structure. The second component data may indicate components disposed in the support structure at a second time. The method may also involve comparing the first component data with the second component data and determining whether the first component data match the second component data.

摘要： Disclosed are methods, computer program products, apparatus, and systems for controlling sending and receiving of universal serial bus (“USB”) messages between a plurality of host computers and a USB device over a data network. A first USB server is in communication with a first one of the host computers and the data network. A second USB server is in communication with a second one of the host computers and the data network. A USB client is in communication with the data network and the USB device. A first control path is established between the USB client and the first USB server, and a second control path is established between the USB client and the second USB server. A data transfer path is established between the USB client and the first USB server. The data transfer path enables sending of data between the USB client and the first USB server over the data network. A busy message is sent from the USB client to the second USB server over the second control path when the data transfer path is established with the first USB server.
