Patent number: 8923292Abstract: The invention relates to enabling differential forwarding in address-based carrier networks such as Ethernet networks. There is described a method of and connection controller for establishing connections (76, 77) in a frame-based communications network comprising nodes (71-75 and 78) such as Ethernet switches. The connections are established by configuring, in various of the nodes, mappings for forwarding data frames, such as Ethernet frames. The mappings are from a combination of a) a destination (or source) address corresponding to a destination (or source) node (73) of the connection and b) an identifier, such as a VLAN tag. The mappings are to selected output ports of the various nodes. By using the combination of destination (or source) address AND identifier, the mappings enable data frames belonging to different connections (76, 77) to be forwarded differentially (ie forwarded on different output ports) at a node (75) despite the different connections having the same destination node.Type: GrantFiled: April 6, 2005Date of Patent: December 30, 2014Assignee: Rockstar Consortium US LPInventors: Robert Friskney, Nigel Bragg, Simon Parry, Peter Ashwood Smith, David Allan, Simon Brueckheimer

Method and apparatus enabling improved protection of consumer information in electronic transactions
Patent number: 8924290Abstract: According to a commercial method of the present invention, a merchant forwards transaction data to a consumer. If the consumer accepts the transaction, a payment command is forwarded to a service provider. The service provider selectively applies authentication before approving payment. Once payment is approved, the service provider forwards a payment instruction, including consumer account information, to a payment service. The payment service forwards payment to the merchant and a payment confirmation is returned to the service provider and, through the service provider, to the consumer. The service provider stores information about each transaction performed by each subscriber. Consumer identity is protected because it is only exchanged between the service provider and the payment service, and is not made available to the merchant. In addition, the storage of the transaction information by various devices facilitates the return process and adds marketing capability to the service provider.Type: GrantFiled: April 8, 2013Date of Patent: December 30, 2014Assignee: Rockstar Consortium US LPInventors: Thomas P.

Patent number: 8918538Abstract: Ethernet OAM MEPs are automatically configured in a link state protocol controlled Ethernet network. A node operating in the link state protocol controlled Ethernet network receives a Link State PDU (LSP) containing a TLV having a MEP associated with the Ethernet MAC node ID of a second node in the link state protocol controlled Ethernet network, where the path between the first and second node includes a plurality of links. The node updates a forwarding table to indicate an association between the MEP ID and a Ethernet MAC node ID of the second node. An Ethernet OAM maintenance endpoint is produced in a link state protocol controlled Ethernet network by hashing a Sys-ID to produce a MEP; storing the MEP in a TLV; and forwarding the TLV over the link state protocol controlled Ethernet network in an LSP.Type: GrantFiled: June 30, 2011Date of Patent: December 23, 2014Assignee: Rockstar Consortium US LPInventors: Dinesh Mohan, Paul Unbehagen, Srikanth Keesara

Patent number: 8913500Abstract: Routers in a communications network mark packets of a multi-priority stream to establish a drop precedence of the packets during network congestion. For each packet received, a router employs one of two types of packet-marking mechanisms to associate low drop precedence with a high-priority, out-of-profile packet. One type, called “token bucket with loan bucket,” uses a token bucket to determine whether a packet is in conformance, i.e., in-profile, with a traffic profile and at least one loan bucket to determine whether a high priority, out-of-profile packet may borrow bandwidth. Another mechanism type, called “token bucket with color-exchange queue,” uses a color-exchange queue to delay packet forwarding for a fixed period. During this delay, a high-drop-precedence marking of an out-of-profile, high-priority packet may be exchanged with a low-drop-precedence marking of an in-profile, low-priority packet. The packet-marking mechanisms are useful in improving the quality of video viewing.Type: GrantFiled: July 2, 2013Date of Patent: December 16, 2014Assignee: Rockstar Consortium US LPInventor: Emre Gunduzhan

Patent number: 8902916Abstract: The invention provides a method and network communication equipment for low latency loss-free burst switching. Burst-transfer schedules are determined by controllers of bufferless core nodes according to specified bitrate allocations and distributed to respective edge nodes. In a composite-star network, burst schedules are initiated by any core node. Burst formation takes place at source edge nodes and a permissible burst size is determined according to an allocated bitrate of a burst stream to which the burst belongs. The permissible burst size is subject to constraints such as permissible burst-formation delay, a minimum guard-time requirement, and permissible delay jitter. A method of control-burst exchange between each edge node and each bufferless core node enables burst scheduling, time coordination, and loss-free burst switching. Both the payload bursts and control bursts are carried by optical channels connecting the edge nodes and the core notes.Type: GrantFiled: March 11, 2013Date of Patent: December 2, 2014Assignee: Rockstar Consortium US LPInventors: Maged E.

Patent number: 8893260Abstract: A method and system provide a user device with secure access to an enterprise application in an enterprise network through VPN. The enterprise application is accessed from a user device such that it sends and receives data packets through the VPN client. For this, a request to send packets, originating from the user application, is intercepted by a VPN agent associated with the user application. In turn, the VPN agent associates an address of a loop-back interface with the user application. Thereafter, packets sent by the user application, are re-directed to the VPN client through the loop-back interface. Similarly, packets received by the VPN client from the enterprise network are routed through the loop-back interface to the user application.Type: GrantFiled: December 15, 2009Date of Patent: November 18, 2014Assignee: Rockstar Consortium US LPInventor: Biju Sadasivan

Patent number: 8891549Abstract: A network architecture enables the data flow of packets to be dynamically modified depending upon the operational needs of the packet being processed. This allows for separate processing of control and data path operations, as well as providing a mechanism for functions that require high computational support, such as encryption functions for example, to be offloaded onto processing devices that can support such functions. Other, less computationally intensive or lower priority functions can be forwarded to PEs having lower operation capacity. With such an arrangement, a dynamic mechanism is provided for customizing the data path of a network device to accommodate the computation needs of any application.Type: GrantFiled: October 24, 2003Date of Patent: November 18, 2014Assignee: Rockstar Consortium US LPInventor: Siva Subramanian
