Consistent sampling for network traffic measurement
InactiveUS6873600B1Reduce ambiguityIncrease choiceError preventionFrequency-division multiplex detailsHash functionNetwork measurement
Traffic measurement should make it possible to obtain the spatial flow of traffic through the domain, i.e., the paths or trajectories followed by packets between any ingress and egress point of the domain. A method of sampling packet trajectories in a packet switching network allows the direct inference of traffic flows through a measurement domain by observing the trajectories of a subset of all packets traversing the network. A method which assumes that the measurement domain does not change comprises the steps of selecting packets for sampling in accordance with a sampling function of the packet content and generating a practically unique label for each sampled packet. The method does not rely on routing state, its implementation cost is small, and the measurement reporting traffic is modest and can be controlled precisely. Using the same hash function will yield the same sample set of packets in the entire domain, and enables us to reconstruct packet trajectories. An alternate embodiment which assumes no constraints and that the measurement domain may change comprises the steps of applying a sampling function and altering an invariant bit position as a signaling flag in each packet selected for sampling.

Cross stack rapid transition protocol
ActiveUS7480258B1Fast rebuildError preventionFrequency-division multiplex detailsTraffic flowComputer science
A cross stack rapid transition protocol is provided for permitting multiple network devices organized as a stack to rapidly transition their ports in response to network changes so as to minimize traffic flow disruptions while avoiding loops. Each switch in the stack has a stack port that connects the switch to another switch in the stack, and a plurality of ports for connecting the switch to other entities of the computer network. Each switch includes a Spanning Tree Protocol (STP) entity that transitions the ports of the switch among a plurality of states including a forwarding state and a blocking state. Each switch also tracks which other switches are members of the switch stack. The stack port of each switch is transitioned to the forwarding state, and a single switch having connectivity to a root is elected to be a Stack Root. One or more other switches may have Alternate Stack Root Ports, that provide alternate paths to the root. If the current Stack Root loses connectivity to the root, the switch whose Alternate Stack Root Port represents the next best path to the root issues one or more proposal messages to the other members of the switch stack. These other members respond with an Acknowledgement, and the former Stack Root transitions its port to the blocking state. Once the proposing switch receives an Acknowledgment from all other active members of the switch stack, it transitions its Alternate Stack Root Port to the forwarding state so that network messages can be forwarded to and from switch stack.

A transceiver in a vehicle-to-vehicle (V2V) communication and safety system that regularly broadcasts safety messages, comprising location, heading and speed, of a subject vehicle, that are free of MAC and IP addresses. The V2V system uses the location of the subject vehicle for vehicle identification, in place of a pre-assigned vehicle ID. Some embodiments broadcast safety message in self-assigned time slots in a synchronized TDMA broadcast architecture, with unusually short inter-message gaps and unusually short messages. The TDMA frame is partitioned into three prioritized time interval classes with differing priorities and dynamically changing sizes based on demand of higher-priority messages. Time slot selection uses weighted algorithms. Selected time slots are held until either a message collision or a timeout occurs. A transceiver equipped vehicle may proxy a different subject vehicle. Embodiments include optimized traffic flow and signal timing.

Dynamic traffic conditioning
Multi-media networks will require that a data flow be given certain quality-of-service (QOS) for a network connection but pre-negotiation of this sort is foreign to the current data networking model. The real time traffic flow in the data network requires distinct limits on the tolerance to delay, and the variations in that delay. Interactive voice and video demand that the total delay does not exceed the threshold beyond which human interaction is unacceptably impaired. The present invention allows the network to discover the nature of the service for each traffic flow, classifies it dynamically, and exercises traffic conditioning by means of such techniques as admission control and scheduling when delivering the traffic downstream to support the service appropriately.

Network policies are managed based at least in-part on user / entity identity information with: a state monitor operable to monitor for state change events in user / entity state and related, network state or in traffic pattern and traffic flow state; an identity manager operable to obtain and validate user credentials; and a policy manager operable in response to a state change event detected by the state monitor (either the identity manager or a defense center) to select a policy based in-part on the user identity obtained by the identity manager or security context obtained by the defense center, and to prompt application of the selected policy. The policies are indicative of user / device authorization entitlements and restrictions to utilization of certain network resources, network services or applications. Dynamic policy selection and targeted responses can be used, for example, against a user who gains network access with stolen user ID and password, and subsequently attempts malicious behavior. In particular, the malicious behavior is detected and identified, and the malicious user can then be restricted from abusing network resources without adversely affecting other users, groups, network devices, and other network services.

Method and apparatus for dynamic proxy insertion in network traffic flow
In embodiments of the invention, a method and apparatus for dynamic proxy insertion in network traffic path is described. According to one or more embodiments of the invention, a request and / or response message may be modified to include one or more thru-proxy tags to identify a network (or traffic) node (e.g., a proxy, server, or intermediary). For example, a request directed to a server or a response directed to a client may be altered to insert a plurality of intermediate or final destination designations. In so doing, a path of a request or response may be altered dynamically. A thru-proxy tag in a response may be inserted in a related request to identify a destination or node such that the request is sent to the destination in the thru-proxy tag before being sent to an origin server. Thru-proxy tags may be used to identify multiple and / or alternate destinations.

Tie-breaking in shortest path determination
InactiveUS8761022B2Simple calculationLower requirementError preventionTransmission systemsTraffic flowOrder set
A consistent tie-breaking decision between equal-cost shortest (lowest cost) paths is achieved by comparing an ordered set of node identifiers for each of a plurality of end-to-end paths. Alternatively, the same results can be achieved, on-the-fly, as a shortest path tree is constructed, by making a selection of an equal-cost path using the node identifiers of the diverging branches of the tree. Both variants allow a consistent selection to be made of equal-cost paths, regardless of where in the network the shortest paths are calculated. This ensures that traffic flow between any two nodes, in both the forward and reverse directions, will always follow the same path through the network.

Method and apparatus providing automatic RESV message generation for non-RESV-capable network devices
A method and apparatus for providing network resource reservation capability for receiver nodes that either cannot or do not facilitate RSVP processes is provided. A RESV proxy is connected between an anticipated sender node and an anticipated receiver node in a computer network, e.g., a voice over IP network. The RESV proxy can detect an RSVP Path message and determine whether a RESV message is appropriate for the anticipated traffic flow. If it is so determined, the RESV proxy generates and communicates a RESV message through the network back to the anticipated sender node. The appropriateness of a RESV message can be based upon predetermined relationships or logic involving one or more of network parameters, transport parameters, and characteristics of the anticipated traffic flow, and other traffic flow attributes determined from analyzing the RSVP Path message. The RESV proxy can also interface with a policy server on the network to facilitate generation of the RESV message according to one or more of the anticipated traffic flow attributes. Alternatively, the RESV proxy can include the policy server functionality itself.

Detection of nonconforming network traffic flow aggregates for mitigating distributed denial of service attacks
An estimate of a portion of network traffic that is nonconforming to a communication transmission control protocol is used to signal that a distributed denial of service attack may be occurring. Traffic flows are aggregated and packets are intentionally dropped from the flow aggregate in accordance with an assigned perturbation signature. The flow aggregates are observed to determine if the rate of arrival of packets that have a one-to-one transmission correspondence with the dropped packets are similarly responsive to the perturbation signature. By assigning orthogonal perturbation signatures to different routers, multiple routers may perform the test on the aggregate and the results of the test will be correctly ascertained at each router. Nonconforming aggregates may be redefined to finer granularity to determine the node on the network that is under attack, which may then take mitigating action.
