| 20080201403 | Maintaning a View of a Cluster's Membership - A method for maintaining a current view of a cluster's membership comprising the steps of maintaining a list of member nodes and updating the list when a modification thereto is noticed by a first node by receiving a first update message from the first node in a second node, thereafter, sending a second update message from the second node to a third node to propagate the modification and sending to the first node a first confirm message from the second or the third node. A node member of a cluster capable of maintaining a first list of neighboring nodes, maintaining a second list of neighboring nodes sharing a current view therewith and ensuring that the first list matches the second by exchanging messages with neighboring nodes, wherein each message comprises topology information. Upon confirmation that both lists match, the node being capable of sending a confirmation message toward neighboring nodes. | 08-21-2008 |
| 20090164782 | METHOD AND APPARATUS FOR AUTHENTICATION OF SERVICE APPLICATION PROCESSES IN HIGH AVAILABILITY CLUSTERS - A method and communication node that for generate a unique service application process biometric identifier for a service application service application process requesting resources and services to another service application service application process in a High Availability (HA) cluster. The method and communication node further authenticate the requesting service application service application process using the unique service application process biometric identifier and thus allowing communication between the first service application process and the second service application process. | 06-25-2009 |
| 20090190758 | Method and Apparatus for Authentication Service Application Processes During Service Reallocation in High Availability Clusters - A method and communication node for providing secure communications and services in a High Availability (HA) cluster. The communication node comprises an Operating System (OS) that detects an unavailability of a first service application process and switches a second service application process from the first state to the second state, the second service application being selected for taking over service currently provided from the first service application process, the first state and the second state each being associated to a set of rights in the cluster. The OS generates a private key for the second service application process based on its second state. The set of rights associated to the second state allows the OS to replace the first service application process with the second service application process for providing secure communications between the second service application and other service application processes in the HA cluster. | 07-30-2009 |
| 20100150006 | DETECTION OF PARTICULAR TRAFFIC IN COMMUNICATION NETWORKS - A method for detecting a particular data traffic in a communication network having a plurality of nodes comprises: maintaining a list of detecting scans to be applied to an incoming data traffic; receiving the incoming data traffic; and applying a subset of the detecting scans in the list to the incoming data traffic. A network node for detecting a particular traffic in a communication network having a plurality of nodes comprises: a list of detecting scans to be applied to an incoming data traffic; an input for receiving the incoming data traffic; and an inspection chain, which applies a subset of detecting scans in the list to the incoming data traffic. | 06-17-2010 |
| 20110138475 | SYSTEMS AND METHOD FOR PROVIDING TRUSTED SYSTEM FUNCTIONALITIES IN A CLUSTER BASED SYSTEM - A framework for providing cluster-wide cryptographic operations, including: signing, sealing, binding, unsealing, and unbinding. The framework includes an interface module (a.k.a., HAT agent) on each of a plurality of nodes in the cluster. Each HAT agent is configured to respond to an application's request for a cluster crypto operation by communication with other HAT agents in the cluster and utilizing a trusted platform module local to the node where the HAT agent resides. | 06-09-2011 |
