20080229379 | Method and apparatus providing scalability for channel change requests in a switched digital video system - A method, apparatus and computer program product for providing scalability for channel change requests in a Switched Digital Video system is presented. A request for a channel change is received. A determination is made regarding whether a channel requested by the request for a channel change is currently being provided to the settop box. When the channel requested by the request for a channel change is being provided to the settop box then the request for a channel change is buffered for transmission at a later time. When the channel requested by the request for a channel change is not being provided to the settop box then the request for a channel change is immediately sent to an SDV server in communication with the settop box. | 09-18-2008 |
20080320303 | VPN PROCESSING VIA SERVICE INSERTION ARCHITECTURE - In one embodiment, a method can include: (i) sending a request to join a group to a service broker; (ii) receiving from the service broker a list of key servers servicing the group; and (iii) sending registration information to a selected one of the key servers in the list. | 12-25-2008 |
20090097409 | Dynamic Selection Between Active and Passive Probing in Computer Network - In one embodiment, during network operation, it is dynamically determined whether to change from passive probing of communication path metrics to active probing of communication path metrics. | 04-16-2009 |
20090175194 | IP SECURITY WITHIN MULTI-TOPOLOGY ROUTING - A method for IP Security within Multi-Topology Routing is disclosed. Disclosed methods may also include IKE extensions. A route eligible for IPSec protection is injected into a topology routing table. Network traffic can then be protected in accordance with a security session, such as an IPSec session, between a first network node and a second network node and forwarded through a selected topology to take advantage of the service-differentiation capabilities of MTR. | 07-09-2009 |
20100085977 | Optimized Dynamic Multipoint Virtual Private Network Over IPv6 Network - Method and apparatus including registering a first spoke router with a hub router, forwarding an Internet Protocol version Four (IPv4) data packet from the first spoke router to a second spoke router over an Internet Protocol version Six (IPv6) multipoint tunnel via the hub router, transmitting a binding information associated with the first spoke router from the hub router to the second spoke router, and establishing a direct communication path by the second spoke router with the first spoke router based on the received binding information are provided. | 04-08-2010 |
20100227493 | INTERFACE CONNECTION MANAGEMENT USING A REMOVABLE ADAPTER FOR COMMUNICATIONS EQUIPMENT - An interface comprising a docking site having a first electrical connector adapted to interconnect a bus, and having at least one first retainer portion; and an adapter comprising: at least one second retainer portion, wherein the at least one second retainer portion and the at least one first retainer portion are adapted to releasably engage; a second electrical connector, wherein the second electrical connector and the first electrical connector are adapted to engage and interconnect; at least one port adapted to accept at least one modular connector having at least one electrical contact; and at least one electrical interconnect adapted to interconnect the at least one electrical contact with the second electrical connector. | 09-09-2010 |
20130322258 | MANAGING TRACE REQUESTS OVER TUNNELED LINKS - In one embodiment, a head-end node of a tunnel, relative to a tail-end node, receives a trace request, and in response, generates an out-of-tunnel trace request based on the trace-request. The trace request is transmitted in-tunnel to the tail-end node, while also transmitting the out-of-tunnel trace request to at least one subsequent node. The head-end node may then receive a trace response from the tail-end node based on the in-tunnel trace request, as well as a trace response from each of the subsequent nodes based on the out-of-tunnel trace request. | 12-05-2013 |
20140105038 | Media Flow Tracing in Third Party Devices - In one implementation, performance statistics for a provider network are compiled and delivered outside of the provider network. The provider network includes a media trace proxy server that receives a media trace query for a media stream of a customer edge network device. The media trace proxy server initiates a route discovery process on the provider network in response to the request or in response to at least one network device in the provider network being nonresponsive to similar types of media trace queries. The media trace proxy server collects performance statistics from the at least one network device and forwards the performance statistics of the at least one network device to the customer edge network device. The performance statistics may include only those statistics authorized by a subscription level or administrative region of the customer edge network device. | 04-17-2014 |
