    摘要: Methods and systems for supplying media over communication networks are described. In one embodiment, a media supplier determines whether a media object hosted on a web server will be supplied to a client by streaming or not by streaming. Preferably, if the determination is to stream, the media supplier streams the media object to the client. Otherwise, the media supplier preferably allows the host web server to supply the media object to the client. In some cases, the same media supplier may be capable of supplying clients with media objects hosted on any of at least two web servers.

    摘要: A method for operating a server having a maximum capacity for servicing requests comprises the following steps: receiving a plurality of requests; classifying each request according to a value; determining a priority for handling the request according to the value, such that requests with higher values are assigned higher priorities; placing each request in one of multiple queues according to its priority value; and dropping the requests with the lowest priority when the plurality of requests are received at a rate that exceeds the maximum capacity. The server operates according to a session initiation protocol.Classifying each request comprises running a classification algorithm. The classification algorithm comprising steps of: receiving a rule set, each rule comprising headers and conditions; creating a condition table by taking a union of all conditions in the rules; creating a header table by extracting a common set of headers from the condition table; extracting the relevant headers from the header table; determining a matching rule; creating a bit vector table; selecting the matching rule according to data in the bit vector table; and applying the rule to place the message in the appropriate queue.

    摘要: Techniques are disclosed for processing messages in a messaging system, particularly during an overload condition. For example, a method of processing messages of an instant messaging system includes the following steps. A message from a first instant messaging user is received during an overload condition. A message type associated with the received message is determined. The method then decides whether to send the message to a second instant messaging user based on the determined message type of the received message. In another method, processing messages in an instant messaging system includes the following steps. Presence information associated with a first instant messaging system user is received. The presence information is sent to a second instant messaging system user when the second messaging system user requests the presence information associated with the first instant messaging system user.

    摘要: A semiconductor photodiode (18) is formed as a pn-junction between a region (2) of a first conductivity type and a region (6) of a second conductivity type. The region (6) of the second conductivity type is approximately hemispherical. A mini guard ring (8), i.e. a ring of the second conductivity type having a junction depth that is much smaller than the junction depth of the region (6) preferably surrounds the region (6) in order to prevent surface trapping. The photodiode (18) is operated with a high reverse bias so that light falling on the photodiode (18) produces the avalanche effect.

    摘要: A method and system for streaming media objects. A streaming system includes a group of end nodes and at least one core node connected via an overlay network. The end nodes cache segments of media objects and stream the media objects to a client segment by segment. Each end node stores segment indices for locating segments cached on end nodes or a core node in the system. The core node is a dedicated proxy which fetches media objects from a remote media server and streams the media objects to a client when the media objects are unavailable from the end nodes.

    摘要: A peer-to-peer communication system in which a peer communicating with a tracker node on a local torrent can locate and download files that are not currently available from other peers communicating on the local torrent. To enable this, the tracker node maintains collaboration information for a list of files. The collaboration information includes, for each file, a list of locations at which a full copy of the file may be located. The list of locations may include active peers, dormant peers and remote tracker nodes. The collaboration information may be obtained from each peer when it joins a local torrent. Upon joining the torrent, the peer may provide the local tracker node with a list of files that it is willing to serve.
