Improved method, data structure and computer readable medium for searching for digital information files. Files referenced by URLs may be quickly located by finding a minimum unique prefix for the desired URL, breaking the prefix into substrings, and traversing a trie data structure to find indices to another trie data structure that will yield the physical location of the stored digital information file. A node data structure may be used to construct the trie data structures, and may be compressed to allow the tries to occupy less memory, thus allowing the tries to be maintained in memory and less access to storage devices. The result is faster retrieval times for digital information files.

Methods, systems, and computer-readable media are provided for efficiently evaluation Boolean expressions. According to the method, the Boolean expression is expressed using pre-fix notation. Each element in the pre-fix expression is then parsed. For each first operand for a Boolean operation, the value of the operand is determined. This may include evaluating a GUID. When an operator and a second operand are encountered, a decision is made as to whether the second operand should be evaluated. The determination as to whether the second operand should be evaluated is made based upon the value of the first operand and the type of operator. If the second operand need not be evaluated, no evaluation is performed thereby saving time and memory space. The evaluation of the Boolean expression continues in this manner until the entire expression has been evaluated. If the Boolean expression is evaluated as true, the program module associated with the Boolean expression may be loaded. Otherwise, the program module will not be loaded.

A circular buffer in a video delivery server tracks a second copy of a live video stream to provide instant replay capability. When an end-user initiates the instant replay function, the circular buffer is copied to an instant-replay buffer, from which a replay of the video is sent to the end-user. During replay the end-user can use playback functions such as pause, slow-play, freeze frame, etc. Upon leaving the replay function the end user rejoins the live stream. The circular buffer also enables transmission of delayed copies of the live stream, time-shifted by predetermined intervals, which copies are multicasted to end-users. Upon request, an end-user may join a delayed version of interest. This allows the user to replay interesting content by jumping to a time-delayed version without missing the show and to catch up with real-time during e.g. commercial breaks.

A system and method are provided for separately distributing edge-device labels and routing information across routing areas of a computer network. Because the edge-device labels are distributed separately from network routing information, the process of distributing the edge-device labels does not preclude conventional edge-device address summarizations. Illustratively, a novel “label mapping” LSA is employed for distributing the edge-device labels across routing areas. The label-mapping LSA may be embodied as an area-scope OSPF opaque LSA (type 10) or an IS-IS LSP containing TLVs of area scope. Advantageously, the present invention is generally applicable whenever label values are allocated to edge devices in a multi-area computer network and data is “tunneled” through the network from one edge device to another.
