摘要： In one embodiment, packet flows are distributed among groups, such as, but not limited to, queues or links. For example in the context of a bundled interface in which multiple links appear as a single logical interface on each of the sender and receiver, packet flows are distributed among these multiple links by the sender. When one or more links become unavailable, packet flows of the affected links are reassigned to other active links, while packet flows assigned to the unaffected links remain associated with the same link in contrast to prior systems which do not attempt to preserve prior associations between packet flows and links. By maintaining these associations, the receiver of the packets does not need to adjust to the different arrival links of packet flows.

摘要： A switchable transformer architecture is disclosed. The switchable transformer includes a primary winding, a secondary winding, and a tertiary winding, in which either the secondary winding or the tertiary winding establish a signal path to the primary winding, based on the position of switches, enabling transmission to either of two blocks sharing the transformer. The transformer architecture achieves high isolation between sharing blocks and low loss on the signal path.

摘要： The present invention provides a wireless network system that enables direct wireless delivery of a multimedia message from a first MMS user agent to a second MMS user agent. In accordance with one embodiment of the invention, the wireless network system includes a MMS server that receives, from the first MMS user agent, a request to send a multimedia message to the second MMS user agent. The request includes an identification (ID) number of the second MMS user agent. From a core network, for example, the MMS server obtains an Internet address of the second MMS user agent based on the ID number of the second MMS user agent, if the ID number is not an Internet address of the second MMS user agent. Then the MMS server forwards the Internet address to the first MMS user agent to enable the first MMS user agent to wirelessly deliver the multimedia message directly to the second MMS user agent using the Internet address. Therefore, by not involving a MMS server in delivering multimedia messages, a substantial amount of network resources is saved, and delivery speed of multimedia messages is significantly increased. As a result, the performance of the overall network system is greatly improved.
