Abstract: A method for structuring a content distribution overlay network for a peer-to-peer network is presented. The method includes receiving a request from a requesting node for content at a content node. The content node has processing capabilities to process the content for presentation to the requesting node. An overlay network, including the requesting node and the content node, is dynamically assembled after receiving the request for content, where the overlay network is self-organized from available nodes of the peer-to-peer network that are available at a time of the request and based on the content requested. Using the assembled overlay network, a head node of the overlay network determines if a child node in the overlay network has processing capabilities to process the content, where the child node is then assigned to process the content for presentation to the requesting node.

Abstract: An approach is provided that transmits a load balance request from a first peer node to other peer nodes. Some of the peer nodes have assigned transaction tracking responsibilities. The transmitting is performed in response to identifying that the first peer node is performing at a non-optimal level. The first peer node receives responses from the other peer nodes. A determination is made as to whether to handover one or more of the first peer node's transaction tracking responsibilities. If a second peer node is identified to take some of the first peer node's responsibilities, then a handover message is sent from the first peer node to the second peer node that assigns at least one of the first peer node's assigned transaction responsibilities to the second peer node.

Abstract: In a web-based service environment, third party providers need to have varying degrees of access to user data for their complementary services. To prevent third party providers from having broader access than necessary or not adequate levels of access, transferable restricted security tickets are employed to determine an appropriate level of access for third parties. Tickets with expiration and restriction roles define a duration and level of access for a third party. The restrictions are determined through an intersection of the authorizing user's security role and restriction roles defined in the system.

Abstract: There is described an electronic data communication system in which encrypted mail messages for a recipient are sent in two parts: message data encrypted by a symmetric encryption algorithm using a session key and session key data encrypted by an asymmetric encryption algorithm using a public key associated with the recipient. If the recipient uses a webmail service to access the encrypted electronic mail message, the encrypted session key data is sent to a trusted third party server which has access to the private key of the user. The trusted third party server decrypts the encrypted session key using the private key of the user, and then sends the decrypted session key to a remote network device for decryption of the encrypted message. In this way, although the trusted third party has access to the private key of the user, the trusted third party does not have access to any decrypted message.

Abstract: Apparatus, system and method for synchronizing one or more clocks across a communication link. A slave clock may be synchronized to a master clock by means of a synchronization signal sent from the master to the slave clock side of the link. The synchronization signal may be an expected signal pattern sent at intervals expected by the slave side.
