Abstract: A method for establishing or reinforcing a path through an asymmetric network of interconnected nodes includes storing navigation data at one or more nodes, for use by an agent in traveling from that node to a subsequent node, while ultimately traveling from a first terminal node (for example, a source node) to a second terminal node (for example, a destination node). As the agent travels from a first terminal node to a second terminal node via an intermediate node, the agent modifies the navigation data intended for use by an agent traveling from the second terminal node to the first terminal node via the intermediate node. Agents traveling complementary routes reinforce each other paths, allowing paths to be determined and reinforced.

Abstract: Methods and systems for optimizing voice call setup times for user devices. A user device that is registered to a packet switched network and in an idle state receives a command to establish a voice call. The user device selects a legacy cell of a circuit switched network. The user device then establishes a radio connection with the selected legacy cell without first establishing a radio connection with a serving cell of the packet switched network.

Abstract: A network device receives initial policer limits for a plurality of over-subscribing ingress ports, where the initial policer limits are based on existing bandwidth limits for an over-subscribed egress port associated with the over-subscribing ingress ports. The network device receives a high threshold watermark and a low threshold watermark for bandwidth usage of the over-subscribed egress port, and identifies a queue, associated with the over-subscribed egress port, with values outside the high threshold watermark or the low threshold watermark. The network device reduces the initial policer limits for the plurality of over-subscribing ingress ports when the queue has values above the high threshold watermark, and increases the initial policer limits for the plurality of over-subscribing ingress ports when the queue has values below the low threshold watermark.

Abstract: The present disclosure provides for devices, systems, and methods which optimize throughput of bonded connections over multiple variable bandwidth logical paths by adjusting a tunnel bandwidth weighting schema during a data transfer session in response to a change in bandwidth capabilities of one or more tunnels. By making such adjustments, embodiments of the present invention are able to optimize the bandwidth potential of multiple connections being used in a session, while minimizing the adverse consequences of reduced bandwidth issues which may occur during the data transfer session.

Abstract: Methods, systems, and computer readable media for improved multicast scaling through policy based redirection are disclosed. According to one method, a packet belonging to an Internet protocol multicast (IPMC) stream is received, where the packet includes packet routing information. A lookup is performed in a IPMC forwarding database (FDB) and, in response to failing to locate an entry in the IPMC FDB, an attempt is made to insert the packet routing information in the IPMC FDB. In response to failing to insert the packet routing information in the IPMC FDB, a packet redirection rule is created based on the packet forwarding information.

Network access requests may be accompanied by compliance/certification/compatibility information for the requesting device as well as intervening devices. A network authentication device may evaluate the request and associated compliance/certification/compatibility information to select one or more network features to allow the requesting device to utilize.

Abstract: A grid router includes a plurality of external interface units to receive packets of services from one point and to provide packets of services to another point and a second plurality of mailbox units to store and forward the packets associated with mailboxes, one per service. Each mailbox unit is connected to each external interface unit. The units are implemented on PCs (personal computers) having memory controllers and move the packets through the router close to or at the I/O (input/output) rate of the memory controllers.

Abstract: A network signals an allocation (PDCCH) for a downlink shared channel (PDSCH); and also signals an indication (reference signal RS) whether a resource block (PRB) comprising the allocated downlink shared channel is used for a control channel transmission (E-PDCCH). Examples include the E-PDCCH being time or frequency multiplexed with the PDSCH; and the indication being a different RS sequence (at least one element being phase shifted) than an original RS sequence used if the PRB were not used for the E-PDCCH. The UE tests for the phase shift by blind decoding. If the phase shift is present the UE a) decodes a portion of the PRB for data if the network is using TDM for its E-PDCCH/PDSCH multiplexing, orb) decodes the full PRB only for the E-PDCCH if the network is using FDM for its E-PDCCH/PDSCH multiplexing.

Abstract: A communication system includes a first communication terminal, a second communication terminal that has not established communication with the first communication terminal, and a third communication terminal that has established communication with the first communication terminal. The second communication terminal transmits to the first communication terminal a request packet that requests establishment of communication, and receives from the first communication terminal a permission packet that permits establishment of communication. The second communication terminal then establishes communication with the first communication terminal and performs communication with the first communication terminal.

Abstract: The invention is directed to a method and system for efficiently distributing Inverse Multiplexing over ATM (IMA) filler cells on IMA logical links having inactive or unusable IMA sub-links. Inactive IMA sub-links are identified during round-robin distribution of ATM data cells to active IMA sub-links. Predefined IMA filler cells are transmitted simultaneously on the identified inactive IMA sub-links when an ATM data cell is transmitted on an active IMA sub-link, thereby reducing the delay between transmitting ATM data cells.

Abstract: The deployment and scaling of a network of electronic devices can be improved by utilizing one or more network transpose boxes. Each transpose box can include a number of connectors and a meshing useful for implementing a specific network topology. When connecting devices of different tiers in the network, each device need only be connected to at least one of the connectors on the transpose box. The meshing of the transpose box can cause each device to be connected to any or all of the devices in the other tier as dictated by the network topology. When changing network topologies or scaling the network, additional devices can be added to available connectors on an existing transpose box, or new or additional transpose boxes can be deployed in order to handle the change with minimal cabling effort.

Abstract: Techniques disclosed herein include features and methods that extend functionality of provider networks including Provider Backbone Bridges (PBB) networks. Techniques include using a portion of information within Ethernet address encapsulation headers for purposes other than identifying source and destination device addresses. The system limits a number of bits in an address header that should be considered by a provider network node when doing an address lookup in forwarding tables of a provider network node, such as by masking the portion of bits or otherwise disregarding that portion of bits during address lookup. The remaining bits in the address field(s) become free bits that can be used for a variety of application purposes, such as flow path selection. By using information fields that already exist in the Mac-In-Mac (MIM) encapsulation header, such Techniques provide additional information without increasing packet size or requiring new protocols.
