20090003231 | Transparent signaling agent - In today's network, enhancing or otherwise modifying signals in bearer flows in or at equipment already deployed in a network may be done by modifying or upgrading existing equipment, or otherwise invasively routing signals through identified network elements. In accordance with example embodiments of the present invention, signals for control plane flows are transparently monitored using policy based routing to direct control signals from a routing point to a signaling monitoring point. Bearer plane address information of a selected media processing point is substituted for other bearer plane address information in the control signal in a manner that causes subsequent bearer flows to be directed to the selected media processing point from the routing point by destination based routing. Bearer flows may be directed to a media processing point to apply signal enhancement to an encoded media signal on the bearer flows to produce an enhanced media encoded signal. Such embodiments enable service providers to upgrade networks with media processing in a low-cost, non-invasive manner. | 01-01-2009 |
20090135724 | Method and apparatus of RTP control protocol (RTCP) processing in real-time transport protocol (RTP) intermediate systems - Media processing of real-time protocol (RTP) packets used in Voice over Internet Protocol (VoIP) and other time sensitive applications makes efficient use of network resources, e.g., by dropping or changing the size of certain packets, but hinders measuring and reporting end-to-end reception quality. Because media processing changes RTP packets between a sender and receiver, causing a difference between what is sent and received, end-to-end reception quality cannot be measured validly without accounting for these changes. Accordingly, a method and corresponding apparatus are provided to track changes to RTP packets of an RTP session caused by media processing of the RTP packets, modify RTP packet information of the RTP packets based on the tracked changes, correct RTP control protocol (RTCP) packets corresponding to the RTP session based on the tracked changes, the corrected RTCP packets being a measure of the end-to-end reception quality of the RTP session, and report the end-to-end reception quality of the RTP session by forwarding the corrected RTCP packets. | 05-28-2009 |
20090135735 | Method and apparatus of RTP control protocol (RTCP) processing in real-time transport protocol (RTP) intermediate systems - Media processing of real-time protocol (RTP) packets used in time sensitive applications makes efficient use of network resources, e.g., by dropping or resizing the packets, but hinders measuring and reporting end-to-end reception quality. Because media processing causes a difference between what is sent and received, end-to-end reception quality cannot be measured validly without accounting for this difference. Accordingly, a method and corresponding apparatus are provided to track changes to RTP packets of an RTP session caused by media processing, modify RTP packet information of the RTP packets based on the tracked changes, correct RTP control protocol (RTCP) packets corresponding to the RTP session based on the tracked changes, the corrected RTCP packets being a measure of the end-to-end reception quality of the RTP session, and report the end-to-end reception quality of the RTP session by forwarding the corrected RTCP packets. Thus, end-to-end reception quality can be validly measured and reported. | 05-28-2009 |

20100177992 | Compressible and Storable Bags and Items - Compressible bags, towels, blankets, and apparel are disclosed. In one embodiment, a compressible bag includes a generally circular channel on one sidewall. A flexible, elongate member or drawstring extends through the channel and protrudes from an opening in it. The bag can be compressed by folding toward the area defined by the channel and pulling the drawstring, causing the area defined by the channel to be drawn up and around the bag, thereby compressing and encapsulating it. In an alternate embodiment, a channel with a drawstring may extend around the circumference of the bag. Towels, blankets, and apparel according to embodiments of the invention also have a generally circular channel on at least one wall with a flexible, elongate member therein. | 07-15-2010 |
