20090307356 | IP ADDRESS ALLOCATION IN A NETWORK ENVIRONMENT - A network access server (NAS) provides a connection to a user in a data communications network, where the NAS is capable of communicating with a home gateway server (HGS) maintaining a pool of IP addresses for allocation to authorized users associated with the NAS. The NAS includes a first memory for storing an identification of a user, an requester for asking the HGS for an IP address on behalf of the user; and a second memory associated with the first memory for storing the IP address of the user received from the HGS. The NAS may further include a detector for periodically detecting connection of the user to the NAS and a keep-alive sender for periodically informing the HGS that the user is still connected to the NAS, a receiver for receiving periodic queries from the HGS about the status of the user connection to the NAS and a responder responsive to said periodic queries for informing the HOS that the use is still connected to the NAS, and/or a receiver for receiving periodic signals from the user and a forwarder responsive to said receiver for forwarding information to the HGS that the user is still connected to the NAS. A home gateway server (HOS) provides mechanisms to assign an IP address to a user via a NAS, and to monitor the status of the IP address after assignment. | 12-10-2009 |

20120233473 | Power Management in Networks - In one implementation, the power consumption by network devices may be managed by accessing a routing protocol that manages an allocation of processing resources in a network. The routing protocol may be used for generating a first configuration, for which a utilization of resources may be determined. A first cost for the first configuration may be determined. A second configuration may be identified to support the utilization of the resources. A second cost may be determined for the second configuration. The first cost may be compared to the second cost. The prospective performance of the network for the second configuration may be assessed. Based on the results of the comparison and the assessment, the network may be configured to use the second configuration. Processing resources may be activated on inactive network devices to support the second configuration and deactivated on active network devices that are not utilized in the second configuration. | 09-13-2012 |

20130003728 | PROVIDING EXTENDED ADMINISTRATIVE GROUPS IN COMPUTER NETWORKS - In general, techniques are described for providing extended administrative groups in networks. A network device comprising an interface and a control unit may implement the techniques. The interface receives a routing protocol message that advertises a link. This message includes a field for storing first data associated with the link in accordance with the routing protocol. The field is defined by the routing protocol as a field having a different function from an administrative group field defined by the same routing protocol. The control unit determines that this field has been repurposed to store second data, wherein this second data specifies an extended administrative group for the link different from those that may be specified by the administrative group field. The control unit then updates routing information to associate the advertised link with the extended administrative group and performs path selection to select paths based on the updated routing information. | 01-03-2013 |

20080320160 | Method and system for enhancing live stream delivery quality using prebursting - The subject matter herein relates to a method to “accelerate” the delivery of a portion of a data stream across nodes of a stream transport network. A portion of a live stream is forwarded from a first node to a second node in a transport network at a high bitrate as compared to the stream's encoded bitrate, and thereafter, the stream continues to be forwarded from the first node to the second node at or near the encoded bitrate. The disclosed technique of forwarding a portion of a stream at a high bitrate as compared to the encoded bitrate of the stream is sometimes referred to as “prebursting” the stream. This technique provides significant advantages in that it reduces stream startup time, reduces unrecoverable stream packet loss, and reduces stream rebuffers as the stream is viewed by a requesting end user that has been mapped to a media server in a distributed computer network such as a content delivery network. | 12-25-2008 |
20100235503 | Method and apparatus for measuring stream availability, quality and performance - A streaming measurement agent designed to experience, measure, and report on a media stream as an actual end user would experience the stream. Preferably, agent resides transparently within a streaming media player itself so that it can monitor stream packet flows within the player as the measured streams are being played. In an illustrative embodiment, the agent comprises a performance monitoring module (PMM), which is software that resides in an interface between an existing core module and a renderer of a media player. The agent PMM intercepts each useful packet as it goes from the core to the renderer and, as a result, it is able to compute quality metrics about the playback. The agent functions “transparently” to the media player by presenting the core with an application programming interface (API) that emulates the API that the renderer normally presents to the core. Thus, when the core believes it is calling the renderer, it is actually calling the agent PMM, which can then receive all the packets from the core and process them. After computing relevant performance metrics using the packets it receives, the agent PMM calls the renderer. A set of performance agents can be managed by a service provider to enable a content provider to determine how a stream is perceived by end users. | 09-16-2010 |
