International Classification:

G06F 1516

US Classification:

709236, 709230, 709235, 709238, 709242, 709245, 370351, 370473, 370474, 370475, 370476, 359117, 379219, 379220, 379242, 710 1, 710 3

Abstract:

A set of packetized fragments in which only a portion of the fragments carry translation information for the set of fragments is translated by storing in a memory fragments received before the translation information. In response to receiving the translation information, the fragments stored in the memory are translated based on the translation information. After receipt of the translation information, fragments are translated as they are received based on the translation information.

Abstract:

A communication system includes a number of communication devices coupled to a data network using communication servers. The communication system supports communication sessions between a variety of networks and devices using, at least in part, XDSL communication techniques. Specifically, information associated with a session passes between a device and an associated server using a modifiable number of XDSL modems and associated twisted pair lines.

International Classification:

G06F 1516

US Classification:

709225, 713201, 709227

Abstract:

A method is provided for blocking attacks on a private network ( ). The method is implemented by a routing device ( ) interconnecting the private network ( ) to a public network ( ). The method includes analyzing an incoming data packet from the public network ( ). The incoming data packet is then matched against known patterns where the known patterns are associated with known forms of attack on the private network ( ). A source of the data packet is then identified as malicious or non-malicious based upon the matching. In one embodiment, one of the known forms of attack is a denial of service attack and an associated known pattern is unacknowledged data packets. In another embodiment, one of the known forms of attack is an address spoofing attack and an associated known pattern is a data packet having a source address matching an internal address of the private network ( ).

International Classification:

H04N 7/10
H04N 7/173

US Classification:

725 35, 725 87

Abstract:

A method, apparatus and system for programming media content on an aggregated media on-demand network are provided which models the MoD network by identifying a plurality of distribution channels that provide media content to a plurality of targeted consumers associated with a specified passion area and generating consumer profile information for the plurality of targeted consumers. As distribution rights over the MoD distribution channels are established and performance parameters for the MoD network are measured, the MoD network may be programmed with media content based on the consumer profile information for the plurality of targeted consumers, the performance parameters for the aggregated media on-demand network, and content profile information for the media content.

International Classification:

H04L 1228

US Classification:

370401

Abstract:

A communication system includes an access server that communicates information between a wide area network (WAN) and a local area network (LAN). The access server includes a WAN interface, a switch fabric, a number of route processors, and a LAN interface. The switch fabric directs information from the WAN interface to a selected route processor based on its loading characteristics.
