摘要： The present invention relates to a synchronized timestamp mechanism in a packet processing system. This synchronized timestamp mechanism provides a globally synchronized counter value so counters located on separate packet processing cards can be synchronized. The synchronizing of these packet processing cards provides tracking of how long it takes for packets to be processed, provides the ability to generate packet headers that include sequence numbers for robust header compression, and allows the use of encryption protocols without a time reference signal. The synchronization is provided by sending the cards with counter value information and this information can be used to update the card's internal counter value information so that the card is synchronized with other cards.

摘要： Techniques for providing an uninterrupted data stream to a mobile node are disclosed. In a first technique, a time stamp is inserted at some point in the wireless network and the time stamp is used along with a tolerance value to determine when to transmit a packet in a data stream. By transmitting the packets at the same adjusted time, transmission to mobile nodes is synchronized. A second technique uses duplication of data stream content to avoid an interruption in the data stream at a mobile node. A third technique uses an error correcting code to avoid interruption of the data stream at a mobile node. A fourth technique uses a sequence number inserted into packets in the data stream at the content server to synchronize transmission to mobile nodes.

摘要： A method for coordinating and controlling multiple data streams representing a data transmission session that terminate in different termination units (such as network access servers) using a virtual data stream tunnel is presented. The data streams are transmitted over two or more links, collectively forming a "bundle. One of the termination units that receives a data stream is designated as the termination unit to receive and reconstruct a call. The designated termination unit is the "owner" of the bundle. A termination unit that is a not a bundle owner creates a virtual tunnel to the termination unit that is the bundle owner, and sends data streams through the virtual tunnel to the bundle owner to reconstruct the call. The designated termination unit reconstructs the data streams for the bundle and directs the bundle to a destination.

摘要： A method for coordinating and controlling multiple data streams representing a data transmission session that terminate in different termination units (such as network access servers). The data streams are transmitted over two or more links, collectively forming a "bundle". The termination units are linked together preferably over a local area network. One of the termination units that receives a data stream is designated as the termination unit to receive and reconstruct the call. The designated termination unit is the "owner" of the bundle. The termination unit broadcasts an advertisement consisting of a bundle mapping update packet software structure with an identification header to alert the other termination units that it is to reconstruct the call. The identification header in the advertisement notifies the other termination units that if they should receive a portion of the data stream in the bundle, they should forward their packets of data to the designated termination unit. The sharing of bundle information between the termination units gives a great deal of flexibility in the design and type of termination units that may be employed.
