A method and system for streaming software applications to a client uses an application server having a library with the application files stored therein. A streaming manager is configured to send the application files to a client as a plurality of streamlets, each streamlet corresponding to a particular data block in a respective application file. A streaming prediction engine is provided to identify at least one streamlet which is predicted to be most appropriate to send to a given client at a particular time in accordance with a prediction model reflecting the manner in which the application files are loaded and used by the application. In the preferred implementation, the application files are preprocessed and stored as a set of compressed streamlets, each of which corresponds to a file data block having a size equal to a code page size, such as 4k, used during file reads by an operating system expected to be present on a client system. In addition, the server is configured to send a startup block to a new streaming client containing a file structure specification of the application files and a set of streamlets comprising at least those streamlets containing the portions of the application required to enable execution of the application to be initiated.

Bandwidth allocated between the traffic classes of a network path is dynamically reallocated when one or more traffic classes have insufficient available bandwidth to support a service request for the traffic classes, wherein the reallocation occurs without modifying the traffic class bandwidth allocations enforced by router mechanisms. A provisioning system maintains an available bandwidth indication for each traffic class, which indications are decremented as a service request is admitted to the path. If a requested traffic class has insufficient available bandwidth to support a request, one or more other traffic classes can loan bandwidth to the requested traffic class by decrementing the available bandwidth indicators for the one or more other traffic classes in the amount of the insufficiency, thereby indicating that less bandwidth is available in these classes for future requests. The provisioning system also maintains an indication of the amount of bandwidth each traffic class loans to the other traffic classes.

A method of adaptively routing voice packets in an IP network receiving a request for a new call at a voice gateway, determining a destination gateway for the new call, determining an availability of at least one route for routing the new call across the IP network to the destination gateway, and deciding whether to admit the new call into the IP network based on whether a route is available over which voice packets for the new call can be routed. A call admission decision is made based on whether a direct, single-path route or a two-path route is available, where each path is an LSP tunnel whose availability is determined using a token bucket technique. If no route is available, the voice gateway does not admit the call into the IP network.
