摘要： When a wireless communications device determines that a microwave oven or other source of periodic interference is operating nearby, the device may rapidly increase the size of its contention window to reduce the number of retries that it attempts during the period of interference. Similarly, it may rapidly decrease the size of the contention window during the periods of non-interference. In some embodiments, the maximum size of the contention window derived during periods of interference may be sized to assure enough time for successful completion of at least one transmission during the next period of non-interference.

摘要： Various embodiments directed to a radio frequency (RF) environment aware wireless communication device to analyze interference characteristics of at least one interferer in the presence of interference in an RF communications channel and to selectively perform one or more adaptation mechanisms for adjusting properties of a communications protocol based on the interference characteristics of the at least one interferer. The interferer may comprise a non-communicating device (e.g., microwave oven) or a communicating device (e.g., baby monitor, cordless phones, Bluetooth device, etc.) operating within or in the vicinity of a wireless network. The adaptation mechanisms may comprise contention window control to backoff and defer transmission according to a contention window and to leave a backoff counter of the contention window unchanged if the interference is determined to be non-802.11 interference. The adaptation mechanisms may comprise aggressive transmission to transmit over the interference. Other embodiments are described and claimed.

摘要： A modular reconfigurable multi-server system for use in a wavelength-division-multiplexed based photonic burst switched (PBS) network with variable time slot provisioning. An optical high-speed I/O module within the multi-server system enables it to serve as an edge node in the PBS network. The optical I/O module statistically multiplexes the incoming packets (e.g., IP packets or Ethernet frames) received from a legacy network, generates control and data bursts, which are then scheduled for transmission over the PBS network. The optical I/O module then optically transmits and receives the scheduled optical bursts according to traffic priority and available network resources.

摘要： An architecture and method for performing coarse-grain reservation of lightpaths within wavelength-division-multiplexed (WDM) based photonic burst switched (PBS) networks with variable time slot provisioning. The method employs a generalized multi-protocol label switched (GMPLS)-based PBS label that includes information identifying each lightpath segment in a selected lightpath route. A resource reservation request is passed between nodes during a forward traversal of the route, wherein each node is queried to determine whether it has transmission resources (i.e., a route lightpath segment) available during a future timeframe. Soft reservations are made for each lightpath segment that is available using information contained in a corresponding label. If all lightpath segments for a selected route are available, the soft reservations turn into hard reservations. The stored reservations enable quick routing of control burst that are employed for routing data during scheduled use of the lightpaths.

摘要： An architecture and method for performing dynamic route discovery and time slot reservation provisioning within optical-switched networks. The method employs extensions to the RSVP-TE signaling protocol, which uses various messages to reserve resources. Under a peer routing embodiment, routing trees and resource availability data are maintained by the edge nodes. A lightpath route is dynamically selected based on selection criteria applied to the routing tree data and the availability of resources along the lightpath. Link state information, including resource reservation data, is broadcast by the switching nodes to update the edge nodes of their resource availability. A resource reservation message is passed between nodes defined by an explicit route contained in the message, and resource availability is confirmed for the entire lightpath prior to confirming the resource reservations.

摘要： Routing mechanisms for routing data via a plurality of optical switched (OS) networks, such as optical burst-switched (OBS) networks. A plurality of OBS networks are connected to form an enterprise network, which may further include non-OBS networks such as LANs and the like. Each of the OBS networks is modeled as an autonomous system (AS), and one or more edge nodes of each OBS network are designated as external gateway protocol (EGP) routers. Each EGP router maintains a routing table identifying routes that may be used to reach destination networks. The routing table is dynamically updated via update messages that comprise an extension to the Border Gateway Protocol (BGP) and account for optical routing considerations particular to OBS networks. In response to a routing request, data is sent from an internal node using an internal routing protocol to a BGP router edge node. The BGP router edge node then determines a next network hop based on current routing information in its routing table, and the data is routed using an external routing protocol. At the same time, data is routed within an individual OBS network using an internal routing protocol under which data are sent as data bursts via reserved lightpaths.

摘要： The present disclosure relates to techniques for determining optimal routing paths for computing devices in a network, including selecting an optimal gateway among a number of available gateways. The techniques include gathering data regarding characteristics of a network, including gateways and network access nodes (NANs) in at least one access network. The characteristics can include, e.g., supported frequency bands, communication protocols, signal-to-noise ratio, power, signal noise and quality, slicing information, and whether a network vender is a standalone network vendor or a non-standalone network vendor. In one aspect, the characteristics are obtained using the Mobile Broadband Interface Model (MBIM). The characteristics can be used by devices in determining routing paths based on requirements of individual flows and/or workflows of individual application instances.
