    摘要： A mechanism to dynamically map a multicast session to a transport tree to reduce flooding of egress routers on the transport tree is provided. A mechanism to reduce the length of time in which transient flooding can occur while the transport tree is being chosen or configured is also provided. The disclosed dynamic mapping mechanisms avoid interruption of an established multicast session. One mechanism disclosed provides for remapping of a multicast session by cloning an original transport tree with which the multicast session is associated, associating the multicast session with the cloned transport tree, and then reconfiguring the cloned transport tree in accord with edge egress routers that have subscribers to that multicast session.

    摘要： Combining parallel Hypertext Transfer Protocol (HTTP) connections and pipelining overcomes an impact of increasing Round Trip Time (RTT) by varying in real time the number of parallel connections and pipelined requests such that the number of outstanding requests is minimal and the link remains fully utilized. Optimal construction and scheduling of requests and connections in an HTTP stack improves page load time and also provides for greater responsiveness to changes in object priorities. Multi-homing and mobility at the application layer for HTTP are addressed. Multi-homing provides for simultaneous use of multiple interfaces, for example WWAN and WLAN interfaces which improves download time, especially in the case that the available bandwidth the interfaces is of the same order of magnitude. Mobility provides for switching connections as the device moves. In combination they provide for smoother mobility. Mobility can be provided this way without server or network support.

    摘要： Methods and apparatuses are provided that facilitate providing an object-based transport protocol that allows transmission of arbitrarily sized objects over a network protocol layer. The object-based transport protocol can also provide association of metadata with the objects to control communication thereof, and/or communication of response objects. Moreover, the object-based transport protocol can maintain sessions with remote network nodes that can include multiple channels, which can be updated over time to seamlessly provide mobility, increased data rates, and/or the like. In addition, properties can be modified remotely by network nodes receiving objects related to the properties.

    摘要： Route changes are processed and filtered to notify a client of those routing updates of interest to a client. In one configuration, a set of network addresses are received from a client indicating route updates of interest to the client and a set of types of routing changes that are of interest. One or more data structures are accordingly populated with this information. In response to receiving a route update, one or more lookup operations are performed on the data structure to identify whether this particular route is of interest to a particular client and/or whether any route dependent on the particular route are of interest to a client. The client is notified of the changes of interest. In one embodiment, the type of change to a route is also matched against a set of types of routing changes that are of interest, and a client is only notified if the change to a route of interest also matches a type of routing change of interest.
