International Classification:

G06F 9/00

US Classification:

726 11, 726 3, 709224

Abstract:

A method for protecting firewall load balancers from a denial of service attack is provided. Packets are received by the firewall load balancer. Each packet has a source and a destination. The firewall load balancer is equipped with a connection database that can contain entries about the packets. Upon receipt of a packet, the connection database is queried to determine whether or not there is an entry for the received packet. If an entry is found in the database, the packet is forwarded to its destination. Otherwise, if the packet was received from a firewall, then a new connection entry for the packet is built and is saved to the connection database and the packet is forwarded on to its destination. If the packet does not have an entry (match) in the connection database and the packet was not received from a firewall, then the packet is forwarded to a firewall.

US Classification:

370401, 370252, 370389

Abstract:

Maintaining a content category cache includes storing the content category cache at a gateway. The content category cache includes content category mappings, where a content category mapping associates content with one or more categories describing the content. A request requesting content for a user is received. One or more categories associated with the requested content are determined from a content category mapping of the content category cache. The requested content is filtered in accordance with the categories.

US Classification:

370392, 37039532

Abstract:

A method for providing single point-of-presence for a network element includes receiving a packet at a network processor, determining if the packet is to be directed to a particular one of a plurality of traffic processors if a source address of the packet is associated with a subscriber terminal, and determining if the packet is to be directed to the particular one of the plurality of traffic processors if a destination address of the packet is associated with the subscriber terminal. The method further includes distributing the packet to the particular one of the plurality of traffic processors.

International Classification:

G06F 15/173

US Classification:

709226, 709224

Abstract:

Techniques for separately accounting for multiple transactions in the same data packets communicated over a network using Transport Control Protocol (TCP) include receiving an Internet Protocol (IP) data packet that includes Transport Control Protocol (TCP) payload data. The TCP payload is parsed to determine boundary data that indicates a byte location on a boundary between a first transaction and a second transaction. A byte count that indicates a number of bytes in the TCP payload associated with the first transaction is determined based on the boundary data. Accounting data for the first transaction is determined based at least in part on the byte count. These techniques allow a service gateway to bill separately for different requests and responses carried in TCP data packets, such as those for Hypertext Transfer Protocol (HTTP) and Real Time Streaming Protocol (RTSP).

US Classification:

709203000, 705040000

Abstract:

An apparatus for managing network access is provided that includes a billing system element operable to receive one or more packets of a communication flow and to communicate with a price server. The price server is operable to receive a query from the billing system element associated with a pricing parameter relating to a data segment to be accessed by an end user associated with the communication flow. The price server is also operable to return a response to the billing system element that includes the pricing parameter relating to the data segment such that the end user can verify the pricing parameter before accessing the data segment.
