Abstract: Access to WebDAV (Distributed Authoring and Versioning) servers is provided in a manner that is essentially transparent to applications. A WebDAV redirector and related components support file system I/O requests and network requests directed to WebDAV servers identified by URI (Universal Resource Identifier) names, or by a drive may be mapped to a WebDAV share. An application's create or open I/O requests directed to a WebDAV server are detected, and result in a local copy of the file being downloaded and cached for local access. When closed, the local file is uploaded to the WebDAV server. Network-related requests such as for browsing that are directed to a WebDAV server are also handled transparently. WebDAV files may be locally encrypted and decrypted at the file system level, transparent to applications and the WebDAV server, via an encrypting file system that performs local encryption and decryption at the local file system level.

Abstract: Large payload files are selectively partitioned in blocks and the blocks distributed to a plurality of distribution stations at the edge of the network qualified to have the data. Each qualified station decides how much and what portion of the content to save locally, based on information such as network location and environment, usage, popularity, and other distribution criteria defined by the content provider. Different pieces of a large payload file may be available from different nodes, however, when a user requests access to the large payload file, for example, through an application server, a virtual file control system creates an illusion that the entire file is present at the connected node. However, since only selective portions of the large payload file may actually be resident at that node's storage at the time of request, a cluster of distribution servers at the distribution station may download the non-resident portions of the file as the application server is servicing the user.

Abstract: A system and method for measuring the performance of a network, such as the Internet, uses a server on the network to collect network performance data in the process of servicing clients on the network. When the server receives a data transfer request from a client, it records operation information such as the time it takes to transfer the requested data, the size of the data, etc. and derives performance evaluation data such as round-trip time, bandwidth, packet loss, etc. that indicate network performance between the client and the server. The recorded performance data for the multiple clients are aggregated and analyzed together with client information to determine the network performance experienced by the clients.

Abstract: Server-side determination of quality of service received by a client. Content is transmitted from the server to the client according to a protocol. During transmission, the protocol requires the client to periodically send the server statistics concerning the transmitting, e.g., lost packets, latency, or the like. The server simulates the network connection between the client and server based at least in part on the received statistics. The simulating allows the server to recreate, server-side, the content received by the client. The server may then compare what was sent to the client, versus the recreated received content, to determine a quality of service received by the client.

Abstract: The invention includes a system and a method for efficiently bounding the life of an event subscription to the availability of an object in a common object server environment. In particular, the invention provides a method for defining a quality of service for a subscription that mandates an automatic cancellation of the subscription when the object subscriber becomes unreachable. In one embodiment this quality of service may be specified as persistent or transient. The administrator can specify administrative limits associated with each or all subscription that determine the frequency with which checks are made. When a subscription with a transient quality of service is created, the event system periodically determines whether the object is reachable or not. If the object is reachable then it does nothing, but if the object is unreachable it may cancel the subscription.

Resource usage accounting may be employed, for example, to make possible run-time enforcement of system operations on one or more subsystems or processing engines of an information management system, such as a content delivery system, for example, to advantageously provide intelligent admission control in a distributed environment. In one embodiment, resource usage accounting may be implemented to make possible the management of system resources on a per subsystem or processing engine basis, for example, based on at least two types of resource utilization indicative information: 1) resource usage that has been tracked internally throughout the life span of the overload and policy finite state machine module; and 2) resource status messages received directly or indirectly from one or more subsystems or processing engines.

Abstract: The present invention concerns packet-based communications networks in which gateways are used to direct communications between terminals. For example, H.323 based communications networks are one example of this type of communications network. One problem relates to how such gateways can be enabled to direct communications between terminals in such a way that takes into account cost information and/or the fact that telephone numbers (or other identifiers) are repeated in different parts of the communications network. This is addressed by providing a gatekeeper with cost information associated with each gateway. An originating gateway sends a request to the gatekeeper comprising a unique identifier of that originating gateway and an identifier for a destination terminal. The gatekeeper uses this information to provide a reply comprising a list of all possible gateways that can be used to contact the destination terminal or a single preferred gateway.

Abstract: Methods, systems and computer program products for tracking a client's usage of one or more services provided by one or more servers. A client generates and sends one or more metering packets to a census service. Each metering packet includes a time element indicating the client's usage of the one or more services. The time element may include a charged time portion and a free time portion. An authentication element may be included with each metering packet so that the census service can determine whether or not a given metering packet is genuine. A login service communicates to the client whether or not usage should be tracked and indicates a time interval to expire between subsequent metering packets. A session identifier in each metering packet allows multiple sessions to be tracked simultaneously. Upon receiving metering packets, the census service discards redundant metering packets and updates a usage database accordingly.

Abstract: A proxy content server responds to a request message from a user terminal by determining whether the message is a registration request or a content request. If the message is a registration request, the proxy content server maps the user terminal to a registered content server in a memory. If the message is a content request for requesting a content from a server, the proxy content server requests it to send content data to the user terminal if the content server is registered in the memory and the user terminal is mapped to the registered content server. If the user terminal is not mapped to the requested server, the user is not entitled to access the requested server and informed of this fact.
