20090245246 | SYSTEMS AND METHODS FOR IMPROVING PACKET SCHEDULING ACCURACY - A packet scheduler is configured to perform quality of service (QoS) scheduling on a per-data unit basis. A downstream processing engine is operatively connected to the packet scheduler for receiving forwarded packets. A feedback path is operatively connected between the downstream processing engine and the packet scheduler for transmitting a net data unit change value reflecting a change in packet size between an output of the packet scheduler and an output of the downstream processing engine. | 10-01-2009 |
20130083691 | METHODS AND APPARATUS FOR A SELF-ORGANIZED LAYER-2 ENTERPRISE NETWORK ARCHITECTURE - In some embodiments, an apparatus includes a network node operatively coupled within a network. The network node is configured to send a first authentication message upon boot up, and receive, in response to the first authentication message, a second authentication message configured to be used to authenticate the network node. The network node is configured to send a first discovery message, and receive, based on the first discovery message, a second discovery message configured to be used by the network node to identify an address of the network node and an address of a core network node within the network. The network node is configured to set up a control-plane tunnel to the core network node based on the address of the network node and the address for the core network node and receive configuration information from the core network node through the control-plane tunnel. | 04-04-2013 |
20130083700 | METHODS AND APPARATUS FOR CENTRALIZED MANAGEMENT OF ACCESS AND AGGREGATION NETWORK INFRASTRUCTURE - In some embodiments, an apparatus comprises a core network node configured to be operatively coupled to a set of network nodes. The core network node is configured to define configuration information for a network node from the set of network nodes based on a template, where the configuration information excludes virtual local area network (VLAN) information or IP subnet information. The core network node is further configured to send the configuration information to the network node. | 04-04-2013 |
20130083724 | METHODS AND APPARATUS FOR A CONVERGED WIRED/WIRELESS ENTERPRISE NETWORK ARCHITECTURE - In some embodiments, an apparatus comprises a core network node and a control module within an enterprise network architecture. The core network node is configured to be operatively coupled to a set of wired network nodes and a set of wireless network nodes. The core network node is configured to receive a first tunneled packet associated with a first session from a wired network node from the set of wired network nodes. The core network node is configured to also receive a second tunneled packet associated with a second session from a wireless network node from the set of wireless network nodes through intervening wired network nodes from the set of wired network nodes. The control module is operatively coupled to the core network node. The control module is configured to manage the first session and the second session. | 04-04-2013 |
20130083725 | METHODS AND APPARATUS FOR ENFORCING A COMMON USER POLICY WITHIN A NETWORK - In some embodiments, an apparatus includes a core network node configured to be operatively coupled to a set of wired network nodes and a set of wireless network nodes. The core network node is configured to receive, at a first time, a first data packet to be sent to a wired device operatively coupled to a wired network node from the set of wired network nodes. The core network node is configured to also receive, at a second time, a second data packet to be sent to a wireless device operatively coupled to a wireless network node from the set of wireless network nodes. The core network node is configured to apply a common policy to the first data packet and the second data packet based on an identifier of a user associated with both the wireless device and the wired device. | 04-04-2013 |
20130083782 | METHODS AND APPARATUS FOR A SCALABLE NETWORK WITH EFFICIENT LINK UTILIZATION - In some embodiments, an apparatus comprises a core network node configured to be operatively coupled to a set of network nodes. The core network node is configured to receive a broadcast signal from a network node from the set of network nodes, which is originated from a host device operatively coupled to the network node. The broadcast signal is sent via a tunnel from the network node to the core network node, such that other network nodes that are not included in the tunnel do not receive the broadcast signal. The core network node is configured to retrieve control information associated with the broadcast signal without sending another broadcast signal, and then send the control information to the network node. | 04-04-2013 |
20140211615 | AGGREGATION NETWORK WITH CENTRALIZED CONTROL - An access network is described in which a centralized controller provides seamless end-to-end service from a core-facing edge of a service provider network through aggregation and access infrastructure out to access nodes located proximate the subscriber devices. The controller operates to provide a central configuration point for configuring aggregation nodes (AGs) of a network of the service provider so as to provide transport services to transport traffic between access nodes (AXs) and edge routers on opposite borders of the network. | 07-31-2014 |
20140212138 | OPTICAL ACCESS NETWORK HAVING EMITTER-FREE CUSTOMER PREMISE EQUIPMENT AND ADAPTIVE COMMUNICATION SCHEDULING - An access network includes an access device having an optical interface module that outputs a plurality of pairs of optical communication signals, each of the pairs of optical communication signals comprising a modulated optical transmit signal and an unmodulated optical receive signal, each of the pairs of optical communication signals having a different wavelength. A customer premise equipment (CPE) comprises an optical interface module to receive the modulated optical transmit signal and the unmodulated optical receive signal for any of the plurality of pairs of optical communication signals. The optical interface module includes a receive module to demodulate the modulated optical transmit signal into inbound symbols and a transmit module having an optical modulator and reflective optics to modulate the unmodulated optical receive signal in accordance with a data signal and reflect a modulated optical receive signal to communicate outbound data symbols to the access device. | 07-31-2014 |
