摘要： A method and apparatus for providing data communication between stations on a network which optimizes the amount of resources required for a network switch. A first data frame is encoded with a source station identifier for the first station and a source switch identifier for the first switch. The first data frame is sent from the first switch to the second switch. A station list in the second switch is updated to indicate that the first station is associated with the first switch. Subsequent data frames having the same destination as the first switch are sent directly to the second switch. Any switch on the network need only identify the local ports attached to the switch, plus the number of switches on the network. The task of identifying all of the ports on the network is distributed across all switches on the network.

摘要： An address reporting technique for reporting address information in a distributed communication environment retrieves locally owned address information from each of a number of distributed address databases, sorts the address information according to a predetermined sorting scheme, and reports the sorted address information. Each address database is maintained by one of a plurality of interconnected modules. A reporting module reports address information by retrieving locally owned address information from its address database, retrieves locally owned address information from each of the other interconnected modules, sorts the address information according to a predetermined sorting scheme, and reports the sorted address information. The reporting module retrieves the locally owned address information from each of the other interconnected modules by sending a request message to the other interconnected modules and receiving a response message from each of the other interconnected modules including the locally owned address information from the module. A module that receives the request message retrieves locally owned address information from its address database, formats a response message, and sends the response message to the reporting module. The reporting module may indicate a starting address, in which case each module retrieves from its address database a predetermined number of locally owned address entries starting with a first locally owned address entry that is lexicographically greater than the starting address.

摘要： An enhanced spanning tree protocol for data communications networks having a multi-link trunk. In one embodiment, configuration messages are transmitted from boxes of the data communications network. In one embodiment, the configuration messages that are transmitted through all physical links of the same logical link, or multi-link trunk, include the same port Identifier. A network device that receives the configuration messages is therefore able to identify all of the physical links of a logical link. The enhanced spanning tree protocol according to one embodiment of the present invention considers all of the physical links of a multi-link trunk as a single logical link when identifying and removing loops in the data communications network to form a spanning tree.

摘要： Bus access is arbitrated among modules connected to a common bus. Each module has a priority level and an arbitration number assigned to it. More than one module can have the same priority level. For each priority level, the arbitration numbers assigned are unique. When two or more modules attempt bus access at the same time, the one with the higher priority level wins access. If the priority levels are the same but one module has already accessed the bus, the module that has been waiting wins access. If the modules have the same priority level and have been waiting then the module with the highest arbitration number wins access.

摘要： A network hub for interconnection of modular devices, such as Ethernet repeaters, bridges, and routers is provided. Such a network hub efficiently interconnects the modular devices to each other. The inter-module connection is not through standard Ethernet media cabling or interconnections so that the hop count does not exceed one for all external connections, as defined by IEEE 802.3 Repeater Specification. Timing synchronization is provided by a global synchronization mechanism. Collision detection is provided by a series of lines that distribute the collision to all modules connected to the hub. The network hub comprises an inter-module bus having a backplane, the backplane able to connect to a number of modules, a clock, a method for transmitting data received by a first module across the inter-module bus to a second module and transmitting the data to ports of the second module, and a method for synchronizing the data as it is transmitted by the second module to the clock within the hub. With such an arrangement, timing of the data transfers and state exchanges on the inter-module connection are such that all state and timing specifications of the IEEE 802.3 repeater specification are satisfied for all ports on all repeater modules and all stations.

摘要： A hybrid network controller may determine and/or communicate traffic management information for enabling setup and/or handoff of call and/or communication session among femtocells, access points and/or end-point devices. Traffic management information may comprise set-up instructions, handoff instructions, transmit power, neighbor list information, signal quality thresholds, frequency assignments, transmission time, code assignments and/or antenna pattern assignments. The hybrid network controller and/or an end-point device may control handoffs between a communication device external to the communication system and the femtocells, access points and/or end-point devices. Received signal strength, interference levels, SNR, signal path delay, power consumption, traffic loads, bandwidth usage and/or radio resource availability may be monitored and/or analyzed by the hybrid network controller. The hybrid network controller may assign time slots, codes, antenna patterns as well as a serving femtocell and/or AP for a set up and/or a handoff. The information may be communicated via wired, optical and/or wireless interfaces.
