Title: Routing method for optimising link capacity and increasing availability
Inventor: REICHERT CHRISTOPH
IPC: H04L12/56
Filed: 2006-04-27
Abstract: The invention relates to a routing method for optimising a link capacity and increasing an availability in nodes (x, Y1, Y2, Z) and links (L1, L2) of a packet-based communications network, wherein a routed data transmission (DV) is associated with at least two priority steps (PKn, PKe). A high-priority step data transmission (PKe) is subsequently routed. A low-priority step data transmission (PKn) is afterwards routed. For routing the data transmission (DV) routing methods known per se, whose use is adapted to the requirements of each data transmission (DV), are used. The advantages attained by said invention lie mainly in that the optimal link capacity, a high reliability and a quick error reaction for the corresponding data transmission (DV) are simultaneously obtained. Said invention makes it possible to assign each data transmission (DV) to a high priority step (PKe) such as, for example, a real-time requirement data transmission (DV) is routed in priority by the communications network and the low-priority step (PKn) data transmission (DV) is routed on links (L1, L2).

Title: Methods and apparatus for the utilization of mobile nodes for state transfer
Inventor: PARK VINCENT
IPC: H04L12/28
Filed: 2006-09-15
Abstract: Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described.  Various features are directed to a end node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff or the use of a core network node to support state transfer. As part of a handoff state information is obtained by an end node from the current access node in encrypted form and then communicated to the new access node to which the handoff operation is to be completed. The new access node, e.g., base station decrypts the state information and then uses it to support communications with the end node. While the information is communicated to and from the end node over wireless links, since it is encrypted by the first access node it is secure and can be trusted by the receiving, e.g., target, access node.

Title: Systems and methods for facilitating distributed authentication
Inventor: MAYERS CHRIS
IPC: G06F21/20
Filed: 2006-10-06
Abstract: A method for facilitating distributed authentication includes the step of requesting, by a user of a client machine residing in a first domain, access to a resource residing in a second domain. The client machine authenticates the user to an intermediate machine. The intermediate machine impersonates the client machine. The intermediate machine impersonating the client machine requests access to the second domain from a domain controller residing in the second domain. The domain controller authorizes the requested access, responsive to a determination that the impersonated client machine is trusted for delegation. The domain controller transmits to an application server residing in the second domain, authentication data associated with the impersonated client machine. The application server transmits, to the intermediate machine, a launch ticket uniquely identifying a logon token. The client machine provides, to the application server, the launch ticket to access the resource residing in the second domain.

Title: Improvements in and relating to modelling
Inventor: NEWMANN CEDRIC
IPC: G06V10/764
Filed: 2008-03-20
Abstract: The method provides for the fitting of a different distribution to the tail of a distribution of continuous data, than that distribution fitting to the rest of the distribution. By fitting a distribution to this set of occurrences only, better distributions shapes are obtained for that part of a distribution which might otherwise be overly sensitive to individual or small numbers of occurrences. Over sensitivity can make such distributions unreliable in situations where their value is compared with the value of another distribution. A distribution which does not decline quickly to zero is preferred for the tail, for instance a heavy tailed distribution.
