    摘要: A method for multicast load balancing in a wireless network having a plurality of access points. The method includes setting a maximum Internet protocol multicast bandwidth for the access points, receiving an admissions control request from a client at one of the access points, and determining whether the admissions control request from the client is for an admitted or unadmitted multicast stream at the access point. The access point is responsive to the admissions control request for the admitted multicast stream by servicing the admitted multicast stream and to the admissions control request for the unadmitted multicast stream by servicing the unadmitted multicast stream where the bandwidth required for the unadmitted multicast stream, plus that portion of the access point bandwidth currently used for all existing downlink multicast streams, does not exceed the maximum internet protocol multicast bandwidth for the access point.

    摘要: A hierarchical communication system, arranged in a spanning tree configuration, is described in which wired and wireless communication networks exhibiting substantially different characteristics are employed in an overall scheme to link portable or mobile computing devices. Copies of data, program code and processing resources are migrated from their source toward requesting destinations based on request frequency, communication link costs and available local storage and/or processing resources. Each appropriately configured network device acts as an active participant in network migration. In addition, portable two-dimensional (2-D) code reading terminals are configured to wirelessly communicate compressed 2-D images toward stationary access servers that identify the code image through decoding and through comparison with a database of images that have previously been decoded and stored.

    摘要: In an example embodiment, a system and method for aggregating multiple wireless bridge interfaces into a single logical bridge interface. The system includes a master switch with multiple associated wireless modules. Each master switch wireless module selectively broadcasts an associated connection signal. The master switch has an associated aggregation port, which is in data communication with each of the master switch wireless modules and selectively routes data among the master switch wireless modules. The system also includes a slave switch with multiple associated wireless modules. Each of the slave switch wireless modules receives one associated connection signal and establishes a wireless data communication link with the broadcasting master switch. The slave switch also includes an associated aggregation port, which is in data communication with each of the slave switch wireless modules, selectively routes data among the slave switch wireless modules.

    摘要: A power management method that divorces multicast frames for power save stations from DTIM beacons. An access point associates power save stations with a multicast group. Each station has an associated power save interval, the station being in a power save state during the interval, otherwise in an active state. The access point maintains a timer for each station in order to determine whether the station is in an active or power save state. The timer can be reset whenever the station sends an inbound frame. When the access point receives a multicast frame for the group, it buffers the frame until the timer for each member of the group expires, thereby ensuring each member of the group is in an active state, and broadcasts the multicast frame.

    摘要: Techniques are provided to reduce or restrict the bandwidth consumed by multicast video streams on wireless links, such as wireless IEEE 802.11 links. At a central multicast video transcoder apparatus configured to communicate with one or more access point devices operating in a wireless local area network, one or more multicast video streams are re-encoded the one or more multicast video streams to produce a corresponding one or more wireless-friendly multicast video streams that have a reduced bandwidth from a bandwidth of the received multicast video streams. The one or more wireless-friendly multicast video streams are thus adapted for wireless transmission by access point devices to wireless client devices in the wireless local area network. The one or more access point devices receive the one or more wireless-friendly multicast video streams and process the one or more wireless-friendly multicast video streams depending on conditions in a radio channel used by the access point device. The access point devices then wirelessly transmit the one or more wireless-friendly multicast video streams to one or more client devices in a corresponding multicast group.

    摘要: A power-save system for a network with an access point and an associated power-save client. The access point buffers wireless data that includes a unicast frame and a multicast frame. A periodic scheduled beacon message is transmitted with a unicast indication element and a multicast indication element. The unicast element instructs a client to remain awake to receive a buffered unicast frame, which includes a destination MAC address. The multicast element instructs a client to remain awake following the beacon to receive a buffered multicast frame, which includes a destination multicast address designating a multicast group of which the client is a member. At least one beacon message is designated as a multicast delivery beacon. The buffered multicast frame is transmitted following the designated multicast beacon. The multicast element contains a list of entries, each entry corresponding to either a multicast MAC address, multicast IP address, or client identifier.

    摘要: In one embodiment, each network interface of a network device in a computer network may be classified as either a low-speed interface (e.g., wireless) or a high-speed interface (e.g., wired). Illustratively, then, low-speed interfaces may be configured (identified) as external interfaces to external links and high-speed interfaces may be configured (identified) as internal interfaces to internal links. By executing a multiple spanning tree (MST) protocol at the network device with other network devices in the computer network, network devices interconnected with internal links are in a same MST region and internal links within an MST region are preferred over external links between MST regions.

    摘要: Disclosed herein is a redundant network and communication protocol at least including host computers, RF base stations, and roaming terminals. The network may utilize a polling communication protocol such that under heavy traffic conditions, a roaming terminal wishing to initiate communication may be required to wait for at least a predetermined period and determine whether the channel is available for communication. When a hidden terminal is communicating, the roaming terminal may conclude that the communication is taking place upon receiving a polling frame directed to the hidden terminal from the normally silent base station. Inherent redundancy techniques may be used with a spanning tree approach for determining the most efficient pathways from a source to a destination and ensuring that the network adapts to spatial changes or breakdowns within the network.

    摘要: A Mobile Ethernet Protocol that is used to logically extend a “home VLAN”, through an Ethernet/IP “campus network”, to mobile nodes on “foreign subnets”. The network architecture used for Mobile Ethernet is hierarchical and includes a Subnet Context Manager per subnet and a central Campus Context Manager. The protocol is generally based on the standard Mobile IPv4 protocol, but includes significant extensions to standard Mobile IP including using an 802 address as the permanent MN identifier, rather than an IP address, encapsulating and sending Ethernet frames through IP tunnels, and configuring a single Mobile Ethernet HA to provide access to multiple home VLANs wherein Home VLAN bindings for MNs are dynamically established. A MN does not need to be configured with a permanent IP address.
