摘要:
A service is disclosed that discovers information about the logical networks to which a computer is connected and provides that information to applications. The information is keyed to names constructed by the service. There is a mapping between the names and the logical networks. Applications may rely on the names when selecting a configuration to use with a given logical network. The network name may be correlated with other information, such as physical network interface(s) on the computer through which the logical network is accessible, application programming interfaces of the transport protocols supported by the logical network, and the connectivity type of the logical network. Applications are notified when network information provided to them changes or when new information becomes available.

Architecture for a scalable, pluggable multi-party, and distributed multimedia conferencing. A centralized policy and control conferencing component allows the seamless plug-in of different distributed media components (e.g., data, audio/video, messaging) to accommodate client participation in a conference session. The centralized conference control component includes the following: a conference notification service for accepting subscriptions to the conference state and notifying subscribers about changes to that state; a conference policy and roster control service for storing and manipulating conference policy and rosters; a security service for user authorization/authentication based on user identity information; a scheduling service for conference scheduling; an allocation service for allocating the most available media component(s) for a conference session; and, an MCU management service for conference policy and roster management of the distributed media components.

Service invocation information including call routing, reasons for redirections, and similar information are provided to party requesting a communication session and recipients of an enhanced communication system along the call routing path as the request is routed. Some of the information is filtered based on system and/or user defined rules, user permission levels, and comparable aspects.

A communication system has a plurality of collections. Each collection comprises a security boundary within which private data is accessible. Each collection is associated with a director. The directors receive messages that specify domains. When a director for a given collection receives a message, the director identifies one of the collections as being a home collection for the domain specified by the message. If the specified domain's home collection is the given collection or another collection within a given privacy boundary, the director forwards the message to a server pool associated with the specified domain's home collection. Otherwise, if the specified domain's home collection is not within the given privacy boundary, the director forwards the message to the director of the specified domain's home collection.

Enhanced communication systems with various resiliency and survivability aspects are provided. Data center, cluster, network, and load balancer survivability are provided for seamless communication experience in case of data center, cluster, discovery infrastructure, or hardware load balancer failures. Call, data, and authentication survivability are provided through dynamic re-routing over alternative networks, continuous data replication, and alternative authentication mechanisms. Seamless failover is ensured through use of identical signaling protocols and data carried by protocols between primary and backup clusters. Voicemail resiliency is achieved by re-routing calls directed to voicemail over alternative paths such as PSTN connections.

Independent telephony systems are integrated by using symmetric forking from both systems. Calls received by either system are forked to the other system. Thus, a call can be accepted by one of the systems, using its external interfaces, and presented to all devices in both systems. Each system is enabled to leverage internal call control advanced features to enhance overall user experience. Internally inserted parameters to call requests are used between the two systems for preventing endless loop of calls between the integrated systems.

Techniques are disclosed providing secure reservationless conferencing, allowing an organizer to arrange a meeting while off-line from a conferencing server, with the conferencing server still enforcing security for the meeting.

A system and method are presented that enhance the performance of single and multiple-processor servers by taking advantage of the half-duplex nature of many HTTP requests. Upon receipt of an HTTP Get resource request, a single send and disconnect IRP is generated. The semantics of the send and disconnect IRP completion recognizes the half-duplex nature of the transaction by indicating a graceful close of the TCP/IP connection. This send and disconnect IRP is also completed without a queuing stage (queuelessly) on the processor that serviced the client request. To further enhance performance, the server FIN message to the client is included in the last data frame transmitted to the server. The invention also contemplates transmission of a single HTTP get and disconnect request by a client to allow acknowledgementless disconnection of the TCP/IP connection once a requested resource has been sent.
摘要:
A method and system for directing data transfers between applications and devices residing on different computers or devices using an adaptive flow control protocol has been described. When an application or device requests to transfer data with another application or device, adaptive flow control protocol adapts the way data is transferred by observing when an application that is receiving data posts a receive buffer and detects the receive buffer's size. Based upon the application's or device's behavior, the adaptive flow control protocol transfers the data in a mode that is best suited for the application.
