Technique for secure computation
A technique for secure computation obfuscates program execution such that observers cannot detect what instructions are being run at any given time. Rather, program execution and memory access patterns are made to appear uniform. A processor operates based on encrypted inputs and produces encrypted outputs. In various examples, obfuscation is achieved by exercising computational circuits in a similar way for a wide range of instructions, such that all such instructions, regardless of their operational differences, affect the processor's power dissipation and processing time substantially uniformly. Obfuscation is further achieved by limiting memory accesses to predetermined time intervals, with memory interface circuits exercised regardless of whether a running program requires a memory access or not. The resulting processor thus reduces leakage of any meaningful information relating to the program or its inputs, which could otherwise be detectable to observers. |

Distributed generation of hierarchical multicast forwarding structures
In general, techniques are described in which packet replicators of a network device cooperate to generate a distributed hierarchical forwarding structure that the packet replicators then use to replicate and forward multicast packets to multiple output interfaces. For example, packet forwarding engines (PFEs) of a router each receive a new list of interfaces for a multicast packet stream. The PFEs individually construct a hierarchical forwarding structure based on the interface list. The hierarchical forwarding structure specifies interrelationships among the PFEs, which occupy nodes within the hierarchy. Each child PFE determines from the hierarchical forwarding structure the identity of a parent PFE and issues a token, constituting forwarding state for the distributed hierarchical forwarding structure, to the parent PFE. The parent PFE uses the token to identify packets of the multicast traffic to the child PFE during replication and forwarding of multicast packets proceeding according to the hierarchical forwarding structure. |

Routing using global address pairs
The present invention extends to methods, systems, and computer program products for routing using global address pairs. Embodiments of the invention use publicly routable Internet Protocol (“IP”) addresses to represent sites rather than individual hosts. Hosts can be represented by a global address pair, including site public IP address and a node private IP address. Nodes route packets to address processing modules using IP-in-IP encapsulation. An outer header contains a site public IP address and is destined to a site on inter-site links. An inner header contains a node private IP address and is destined to a private endpoint in intra-site links. In some embodiments, a site public IPv4 address and a node private IPv4 address are encoded into an IPv6 address. Use of an IPv6 address makes encoding of the two IPv4 address transparent to IPv6 applications. |

A computer network testing process to determine whether, given a network node that is unreachable by communication attempts from a controller on a control-plane network, the network node is still functioning to forward data packets on a data-plane network, or if the network node is fully non-functional on both the control-plane network and data-plane network. In order to make this determination, the testing process identifies a network node that is still reachable by the controller on the control-plane network, identifies a route between the controller and unreachable node, passing through the reachable node, and constructs an encapsulated test packet that is sent along this route. In response to sending the encapsulated test packet, the controller may, upon receipt of a confirmation packet, determine that the unreachable node is still functional on the data-plane network, or if no confirmation packet is received, mark the unreachable node as fully non-functional. |

Controlled interconnection of networks using virtual nodes
Methods, apparatuses, and systems for controlling interconnections between nodes using virtual nodes are described. A physical node—such as a router, bridge, switch, etc. —stores a virtual cost associated with a virtual link that links virtual nodes of the physical node. A first physical port and a second physical port of the physical node are designated as belonging to a first virtual node and a third physical port of the physical node is designated as belonging to the second virtual node. The first physical port is associated with a first network partition and the second physical port is associated with a second network partition. The physical node transmits a routing information packet that includes the virtual cost. |

Method of congestion detection in a cellular radio system
A method for detecting congestion in a transport network is provided. The congestion detection utilizes flow control including relative bitrate. The method comprises counting the number of detected frame loss events for a flow. The method further comprises determining if the number of detected frame losses is greater than or equal to a corresponding threshold, wherein the threshold used is an individual threshold for the flow set taking into account relative bitrate weights of the flow, and detecting transport network congestion for the flow when the number of detected frame losses is greater than or equal to the corresponding threshold. |

Apparatus and methods for improved packet flow mobility
Methods and apparatus for improved packet data flow mobility and packet data distribution and collection across heterogeneous networks. In one embodiment, a source device with one or more wireless interfaces receives data to be transmitted to a target device. The device sequences the received data with corresponding packet sequence numbers according to characteristics of the service providing the data. The sequenced data is classified according to application/service requirements (e.g., minimum Quality of Service requirements, service type, etc.). The classified data is assigned to available network interfaces, which can support the classifications of the data. The data is transmitted over the assigned network interfaces to the corresponding receiving interface. The data is collected and reassembled according to the packet sequence number at the target destination. |

Traffic distribution across a plurality of attachment circuits of a multihome site with a computer network using hashing algorithm
In one embodiment, an edge device of a core network may receive a plurality of packets from a peripheral network having a plurality of active connections to the core network, where each packet has a destination address and a source address. The edge device may compute a hash on the destination address or the source address of each packet, and determine whether the computed hash corresponds to the edge device. In response to the computed hash not corresponding to the edge device, the edge device may drop the packet, and in response to the computed hash corresponding to the edge device, the edge device may process the packet to forward the packet, where the dropping and processing load balances the plurality of packets over the active connections and prevents formation of loops in the core network. |
