A system for scheduling a conference between callers includes a database that stores scheduling information indicating at least a start time, a duration, and a maximum number of callers for one or more scheduled conferences, the scheduling information reflecting available conferencing resources. A server complex coupled to the database communicates, to a requesting Internet Protocol (IP) user, at least one page including one or more scheduling input fields. The server complex receives scheduling input from the requesting IP user for a requested conference according to the scheduling input fields. The server complex accesses the database to determine, according to the scheduling input, whether sufficient resources are available for the requested conference. If so, the server complex allocates at least some available resources to the requested conference and generates confirmations of the requested conference for communication to the callers.

Provided are a system and method for supporting communication between application programs and the processing of messages by those programs. A table driven approach is used to select appropriate components of modular application programs to process received messages. The selection is carried out in dependence on associations between message types (e.g. request, inform, reply) and other characteristics of the message (e.g. whether the message is an expected reply (as identified by an identifier value). Also used in said selection are dynamic characteristics of the message or the system (e.g. possibly expiry of a timeout, or the state of an application). Rules combine these criteria and determine the conditions for invoking an application program component. Also provided is a mechanism for differentiating between reply messages which are received out of serial sequence but are still current and messages which are invalid.

The subject matter herein generally relates to transcoding content, typically audio/video files though not limited to such, from one version to another in preparation for online streaming or other delivery to end users. Such transcoding may involve converting from one format to another (e.g., changing codecs or container formats), or creating multiple versions of an original source file in different bitrates, frame-sizes, or otherwise, to support distribution to a wide array of devices and to utilize performance-enhancing technologies like adaptive bitrate streaming. A transcoding platform is described herein that, in certain embodiments, leverages distributed computing techniques to transcode content in parallel across a platform of machines that are preferably idle or low-utilization resources of a content delivery network. The transcoding system also utilizes, in certain embodiments, improved techniques for segmenting the original source file so as to enable different segments to be sent to different machines for parallel transcodes.

Multiple service label types may be used in a given network element to optimize scalability of the data plane, minimize overhead associated with service label management, and allow new services to be offered. Service label management may be done in a dynamic manner so that service labels may be selected for routes in a dynamic fashion as the network changes. VPNs handled by the network element may have different types of service labels, and different routes within a particular VPN may be allocated different service label types. Service label requests may be stored on the data plane to allow a service label request database to be restored from the data plane upon a control plane failure, so that new service labels are not required to be allocated after a control plane failure.

A network intelligence provides stateless elemental device control to a plurality of network connected components. Selected ones of the network connected components may be associated with one another as an aggregate device and the state of each associated component may be maintained at the network intelligence in a logical model of the aggregate device. Service adapters in the network intelligence may represent this association of components to data network services as a single, multi-function device.

A system and method are presented for authorizing execution of requested actions transmitted between clients and servers of a data processing system. The method includes receiving a message including a set of actions and simulating execution of the set of actions. A list representing allowable actions and user-definable inputs to the simulated actions is defined. The list of allowable actions and user-definable inputs to the allowable action is then compared to user-requested actions and inputs. When elements within the user-requested actions and inputs are included in the allowable actions and input list, the user-requested actions and inputs are authorized for execution.

The present invention utilizes specific referential tables for forwarding decisions while maintaining current mechanisms of Ethernet addressing and QoS marking. The referential tables are utilized for forwarding decisions based on any and/or multiple fields within the packets simultaneously, such as, for example, incoming port number, incoming MAC, incoming VLAN, outgoing MAC, outgoing VLAN, P-bits, DSCP, MPLS label, TCP/UDP port numbers, IP, SIP, HTTP, and the like. A user can define the forwarding criteria based on any combination/permutation fields in the packet. Advantageously, the present invention removes the need to introduce explicit tunnel labels in the Ethernet frame in order to maintain the desired QoS within the network removing explicit labeling requirements.

A proxy directory server discovers the topology of distributed directory server immediately after starting up and before accepting client requests. Immediately after starting up, the proxy server executes queries to extract the structured data corresponding to directory distribution information from the distributed directory servers. Dynamic topology reconfiguration of the distributed directory is achieved by any dynamic configuration changes made to the topology information directly at the proxy during operation being propagated by means of directory update operations to the distributed directory servers.

A system and method for using hierarchical policy levels for distribution of software in a computer network. In one embodiment, computers of the network are arranged into a hierarchy. A management policy server with access to the network queries the hierarchy to identify computers at or below its own level within the hierarchy. Once a set of computers is identified, software programs, updates or policies are distributed, bypassing human intervention.

A distributed LSR sends data from a first edge LSR, across a non-MPLS network, to a second edge LSR, thereby enabling a non-MPLS network to interface transparently with MPLS networks. This enables a VPN to use a public network to communicate from one portion of the network to another, remote portion. The distributed LSR includes an ingress gateway logically positioned between the first edge LSR and the non-MPLS network. This ingress gateway receives label requests from the first edge LSR. These label requests are multicast to several egress gateways. At least one egress gateway sends a message back indicating that it can transmit data to the destination. In response, the ingress gateway designates that egress gateway to be a designated gateway. The egress gateway then establishes a tunnel through the non-MPLS network to the ingress gateway.

A plurality of logical nodes are identified from a plurality of elements on a network, where the plurality of elements include security devices. One or more path entries may be determined for at least some of the logical nodes. Each path entry is associated with one of the logical nodes and specifies a set of communication packets, as well as a next node to receive the communication packets from the associated node. The path entries are used to characterize at least a substantial portion of a network path that is to carry communication packets in the set of communication packets.

Systems and methods utilize a distributed server network to allow for the optimization of the upload of a data stream from a computing device. Performance metrics are estimated for different network paths from the computing device to a variety of entry servers in the distributed server network. Based on the estimated performance metrics, one or more entry servers are then selected to receive the data stream from the computing device. As a result, the systems and methods described herein allow for high quality upload performance which addresses the first mile vulnerability issues of the data stream. The distributed server network can then transmit copies of the data stream in real-time to other computing devices.
