  • Publication number: 20100091694
    Abstract: A method and system for selecting traffic processors for processing and transmitting broadcast/multicast service flow in a cellular network includes evaluating processor occupancy of a plurality of traffic processors and selecting the traffic processors with the highest available processor occupancy. The cellular network has one or more base stations that are connected to a radio network controller, the radio network controller having a plurality of traffic processors to process the radio signals and data traffic to be transmitted to the base stations. A required processor occupancy for transmitting the broadcast/multicast service flow to the base stations is estimated and the traffic processors are selected such that their combined available processor occupancy is greater than the required processor occupancy for the broadcast/multicast service flow.

  • Publication number: 20100080221
    Abstract: A method is provided for distributing multicast channels from a multicast/predictive multicast cache located in at least one selected network device of a multicast network. The network device upon receiving a channel request from an end-user transmits the requested channel from the multicast cache if the requested channel is available in the multicast cache. Else, the network device requests the multicast source for the requested channel along with a group of one or more multicast channels centered at the requested channel. The network device transmits only the requested channel and other channels are cached in the multicast cache on the network device. Upon receiving a request for removing a channel the network device caches the channel for a prescribed duration before evicting the channel.

  • Publication number: 20100071929
    Abstract: A geometrically-structured coaxial cable may prevent infiltration of water vapor and other contaminants by using a closed cell structure. The cable may be fabricated by wrapping bubble tape around its central conductor. Alternatively, plastic may be extruded through channels to create a plurality of layers. In either case, these layers are staggered in a zig-zag pattern to ensure that no radial spokes connect the inner and outer conductors of the coaxial cable without passing through a plurality of dielectric layers.

  • Publication number: 20100069074
    Abstract: In one embodiment, a wireless-resource broker employs a self-enforcing spectrum-sharing policy, e.g., the expected utility (e.g., rate) a user obtains by following the policy provided by the broker is not less than the expected utility that the user obtains by switching to some other strategy. Each user is associated with one or more transmitter-receiver pairs, e.g., a transmitter of a wireless device and a receiver of a base station in communication via a wireless channel. The broker receives, as input, user parameters characterizing one or more of the transmitters and/or receivers and resource parameters characterizing one or more available spectrum blocks. The broker solves a linear-programming problem to generate and transmit a recommended policy for one or more users. The policy for each user includes information such as the spectrum block(s) to which the user is assigned, the transmission power for the user, and the transmission rate for the user.

  • Publication number: 20100040066
    Abstract: In one embodiment, IP lookup into a routing table having prefixes of different prefix lengths is performed using a Bloom filter that was programmed with the prefixes corresponding to all of the different prefix lengths without having to expand any of the prefixes programmed into the Bloom filter. Membership probes are performed into the Bloom filter using candidate prefix values of a given network address. The Bloom filter can be implemented in a distributed manner using Bloom sub-filters, where each Bloom sub-filter is hashed based on a set of hash functions, where each different hash function in the set corresponds to a different prefix length in the routing table. Each Bloom sub-filter can in turn be implemented using a plurality of practically realizable multi-port memory devices controlled by a port scheduler. False-positive matches can be detected and next-hop information for true-positive matches retrieved using an off-chip, hash-based prefix table.

  • Publication number: 20100020726
    Abstract: In one embodiment, a method for setting up a flow-through mesh group (FTMG) for transmitting link-state packets (LSPs) in a network having a plurality of nodes interconnected by links. The FTMG is a combination of multiple spanning trees for the network through which LSPs are forwarded. FTMG set-up messages are received at ports of each node of the network from peer ports of linked nodes. FTMG set-up messages identify root nodes of the multiple spanning trees and the transmission modes of the peer ports. The FTMG set-up messages are used to determine (1) a root node for each spanning tree, (2) a root port on each node for each spanning tree, and (3) directionality of ports of the nodes. FTMG set-up messages are then used to determine the transmission mode of ports of the nodes and, subsequently, to update the spanning trees and transmission modes, as needed.

  • Patent number: RE41162
    Abstract: Platform and/or application software on all online, machine/servers in a cluster is updated without manually taking each machine/server offline. Initially, platform and/or application software for updating is stored in respective directories in an APPLY phase. Next, the new platform and/or application software is activated with or without a trial/test phase in an ACTIVATE phase. Where the new platform and/or application software is activated with a trial/test phase, a ROLLBACK phase is either automatically or manually invoked by the application in the event of a failure of the new software for backing out the new platform and/or application software and reactivating the previous platform and/or application software. An OFFICLAL phase then transitions the new platform and/or application software to the official state followed by a REACTIVATE phase for reactivating the backup copy of the previous/old platform and/or application software after the new software has been made official.
