Filed:

Jan 11, 2000

Appl. No.:

09/480904

Inventors:

Peter C. Hayden - Mont Vernon NH

Assignee:

Compaq Information Technologies Group L.P. - Houston TX

International Classification:

G06F 1516

US Classification:

709231

Abstract:

Multicast addresses on a computer network are dynamically assigned to a temporary node task. In particular, a server dynamically assigns a multicast address to a data stream in response to a request for the data stream from a client. The server assigns the multicast address in cooperation with other servers from a pool of network-allocated but unassigned multicast addresses. Once the data stream is terminated, the assigned multicast address is deassigned and returned to the pool of unassigned multicast addresses for possible reuse by the nodes.

International Classification:

G06F 12/16

US Classification:

711162, 709203

Abstract:

Systems and methods for providing an efficient partitioned resource server. In one embodiment, the partitioned resource server comprises a plurality of individual servers, and the individual servers support a storage service. The systems and methods provide archiving processes for a partitioned storage service. To this end, the systems and process may include a snapshot process operating on a server and capable of coordinating with other snapshot processes for generating state information representative of the state of the partitioned storage volume.

Abstract:

Systems and methods for providing an efficient partitioned resource server. In one embodiment, the partitioned resource server comprises a plurality of individual servers, and the individual servers appear to be equivalent to a client. Each of the individual servers may include a routing table that includes a reference for each resource that is maintained on the partitioned resource server. Requests from a client are processed as a function of the routing table to route the request to the individual server that maintains or has control over the resource of interest.

Abstract:

The systems and methods described herein include methods for providing resources over a data network. The methods may be embodied as processes operating on a computer server, wherein that server comprises a plurality of server platforms, each of which are truly equivalent in that each provides a functionally equivalent interface to a client. In one practice of the invention, a method responds to client requests by detecting a request from a client for access to a resource and by establishing a connection for communicating with the client. The method then identifies a server available for servicing the detected request, and determines whether state information is associated with the connection. The method then, grants the identified server with access to the state information and allows the identified server to create and transmit a response to the client, also allowing the identified server to update the state information.
