摘要： A packet-based telecommunications architecture is disclosed that, like virtual-circuit networks, preserves the sequential order in which packets are presented to the network, but does not require node-by-node call set-up or tear-down, unlike virtual-circuit networks. Further, the packet switches which compose the architecture can be more simple than those used in datagram or virtual-circuit networks. An illustrative embodiment of the present invention comprises determining the topology of a network of packet switches that are connected by communication links, associating at least two names with at least one of the packet switches, and populating the router tables in the packet switches so that for each name the packet switches and communication links form a elemental network with the topology of a sink tree with the named packet switch at the root of the tree.

摘要： The tracking of mobile terminals served by base stations supported by respective switches are formed into respective peer groups of switches in which the peer groups are then formed into a hierarchical logical network having a prescribed number of levels of scope S, and in which individual ones of the switches serve as a home switch for respective ones of said wireless terminals is enhanced. Specifically, responsive to receiving a registration message sent by one of the wireless terminals, the receiving switch notifies the home switch associated with the sending terminal. The home switch, in turn, notes the current location of that terminal and sends a similar message to the switch serving the zone in which the sending wireless terminal was last located. The latter switch, responsive to receipt of the message sets a pointer that points to (a) the current location of the sending wireless terminal if the switch is within the scope of the current location of the sending terminal or (b) the home switch if the switch is outside of the scope of the current location of the sending terminal.

摘要： Parallel connection control ("PCC") processes and switching networks are described. Various aspects of these PCC processes and networks relate to the provision of an alternative switching connection setup to achieve bandwidth savings or lower cost networks with acceptable setup delay. The new approach provides an alternative to existing switch-by-switch sequential connection setup approaches. In the new approach, segments of the connection are set up by executing operations in parallel. The algorithm and network are also extended to address complex control connection tasks, such as the complex bearer control tasks of third-party connection control, unidirectional multicast connection setup, and multiparty-to-multiparty connection control.

摘要： A system and method for routing ATM cells in a wireless ATM local area network (LAN) that use portable base station (PBS) switching nodes. Routing of cells to and from mobile users within the network is accomplished utilizing a novel routing scheme which preserves cell sequence. Each user transmitting data to another user is associated with a Source Home Station or node and each user receiving data is associated with a Destination Home Station or node. When a connection is established in the network between a first mobile user and a second mobile user, the ATM cells are routed along a fixed path from the first mobile user to the associated Source Home Station and along a fixed path between the Source Home Station to the Destination Home Station and then along a fixed path from the Destination Home Station to the second destination user. In this way cell sequence is maintain by utilizing the Source Home to Destination Home path. Mobile users within the network are also associated with a Local PBS which can be different from the Home Stations as the mobile moves around the network. The Local PBSs associated with the mobile user are slowly updated to be the Home Stations to cure inefficient routing.
摘要翻译：一种用于在使用便携式基站（PBS）交换节点的无线ATM局域网（LAN）中路由ATM信元的系统和方法。利用保留小区序列的新颖的路由方案来实现到网络内移动用户的移动用户的路由。向另一用户发送数据的每个用户与源家庭站或节点相关联，并且每个接收数据的用户与目的地家庭站或节点相关联。当在第一移动用户和第二移动用户之间的网络中建立连接时，ATM信元沿着固定路径从第一移动用户路由到相关联的源家庭站，并沿着源家庭站之间的固定路径路由到目的地家庭站，然后沿着从目的地家庭站到第二目的地用户的固定路径。以这种方式，通过利用源归属到目的地归属路径来维护信元序列。网络中的移动用户也与本地PBS相关联，本地PBS可以随着移动网络周围移动而与家庭站不同。与移动用户相关联的本地PBS被缓慢更新为家庭站，以治愈低效路由。

摘要： A method of automatically queuing calls for later transmission in connection-oriented networks instead of blocking them when network resources are unavailable at the time the request is received, as currently done. A simple call queuing method holds up call setup messages at each switch along an end-to-end path of a network until resources become available. This simple, known queuing method suffers from poor network utilization and long call queuing delays. However, if calls that can be queued have known holding times, a call scheduling method that results in reduced call queuing delays and improved network utilization according to the present invention can be realized.

摘要： The present invention is a system and method for routing cells in a wireless communications network, wherein the communications network includes a plurality of switching nodes and the cells are routed according to destination-rooted virtual path identifier (VPI) trees. The present invention includes a routing protocol for determining preestablished VPI trees rooted at each destination node. The routing protocol manages the routes of these trees, while ensuring that there are at least two VPI trees from each source to each destination for reliability reasons, and that each destination node has multiple VPI trees for load-balancing reasons. The routing protocol includes an off-line procedure for the determination of the initial VPI trees. In order to handle changes in network traffic and conditions, the routing protocol updates the routes of the VPI trees in a dynamic and distributed fashion. These update procedures are triggered by congestion, link/node failures and link/node additions.

摘要： Transferring data (such as files) on an end-to-end, high-speed packet-switched network connection (a “virtual circuit”) or on a circuit. An out-of-band path is used for signaling and status messages (control). The same, or a separate, out-of-band path may be used to retransmit chunks of data that were received with errors or that were not received at all. By simplifying the data being sent over the high-speed (virtual) circuit, the resources of the (virtual) circuit are used efficiently since less overhead is required. Further, since the size of the file to be transferred can be predetermined, and since any retransmissions can be made over a path other than the (virtual) circuit, the (virtual) circuit that best meets the needs of the data transfer can be selected, thereby further increasing the efficiency with which the (virtual) circuit is used.
摘要翻译：在端到端高速分组交换网络连接（“虚拟电路”）或电路上传输数据（如文件）。带外路径用于信令和状态消息（控制）。可以使用相同或单独的带外路径来重传接收到的错误或根本没有收到的数据块。通过简化通过高速（虚拟）电路发送的数据，可以有效地使用（虚拟）电路的资源，因为需要更少的开销。此外，由于要传送的文件的大小可以是预定的，并且由于可以通过（虚拟）电路以外的路径进行任何重传，所以可以选择最能满足数据传送的需要的（虚拟）电路，从而进一步提高使用（虚拟）电路的效率。
