First, a unit that appends an identifier of a service to be provided and an attribute of the service to a communication path establishment control message, and requests path establishment is installed in a source node. Secondly, a unit that determines a requirement for maintenance of the communication path and adaptation on the basis of the service identifier and/or service attribute is installed in each node. Thirdly, maintenance attributes of network resources are compared with the requirement for maintenance in order to determine links and nodes through which the communication path passes. The determined links, nodes, and adaptation are designated as action parameters for a switching unit and/or interface unit. | 2010-02-11 |
20100034206 | DATA STORAGE SYSTEM IN COMMUNICATION NETWORK AND DATA INFORMATION PROCESSING METHOD - The present invention discloses a data storage system in a communication network, which enables distributed storage of data. The system includes front end nodes, storage nodes, super nodes and management nodes. The operation units are located in the front end nodes, the super nodes or the storage nodes and each adapted to operate a first data GUID by a preset fixed offset to derive a second data GUID, to determine, from loop link information obtained from the management node and the second data GUID, a super node with a node identifier closest to the second data GUID, and to forward a service request carrying the second data GUID and a backup flag to the determined super node. The invention further discloses a data information processing method using the system. | 2010-02-11 |
20100034207 | ENFORCING THE PRINCIPLE OF LEAST PRIVILEGE FOR LARGE TUNNEL-LESS VPNs - Techniques for secure communication in a tunnel-less VPN are provided. A key server generates and provides, to each VPN gateway, different, yet mathematically-related keying material. A VPN gateway receives distinct keying material for each designated address block (e.g., subnet) behind the VPN gateway. In response to receiving a packet from one a source host whose address falls within one of the designated address blocks, the VPN gateway identifies the appropriate keying material. The VPN gateway determines an identifier for the address block that includes the destination address. The identifier and the identified keying material are used to generate a key. The VPN gateway encrypts the packet with the key and forwards the encrypted packet to the destination host. | 2010-02-11 |
20100034208 | Buffered Crossbar Switch With a Linear Buffer to Port Relationship that Supports Cells and Packets of Variable Size - A buffered crossbar switch is provided with a buffer to port relationship that supports cells and packets of variable size. A novel scheduler is provided that allows for an efficient crossbar switch, where the relationship between the number of internal buffers is less than the number of ports squared. This allows for a switch that can be implemented that requires less buffer memory. | 2010-02-11 |
