A number of embodiments can comprise a system. The system can comprise an application and one or more software nodes under control of the application, wherein the application is configured to perform: instructing a software node of the one or more software nodes to route data to a target node of the one or more software nodes; analyzing, using a routing engine, associated paths through the one or more software nodes to the target node, wherein the associated paths comprise at least one path traversing both a mobile enterprise network and a virtual enterprise network; selecting one or more candidate next hop nodes of the one or more software nodes based on the analyzing the associated paths; causing the data to be routed to at least one of the one or more candidate next hop nodes, as selected; and repeating the analyzing, the selecting, and the causing until the data reaches a destination. Other embodiments are disclosed here.

Mobile overlay virtual enterprise network and virtual internet for enterprises

An overlay network for use with a data network that routes packets from one location on the data network to another location on the data network, the overlay network comprising one or more software nodes, at least one of the software nodes configured to receive commands from an application, the application including software for generating the commands and sending the commands to the at least one of the software nodes, the commands used by the at least one of the software nodes to control routing of packets, generated by the application, through the data network. In addition, a method of routing packets through a physical network by providing one or more software nodes connected to each other over the physical network to form an overlay network and forming a communications channel between at least one of the software nodes and an application, wherein the application instructs the at least one software node on how to route data over the physical network. Further, a software platform for network communications that includes computer-executable instructions configured to generate a global overlay network, which enables an application to determine a network path through an underlying access network for data generated by the application.

A video session manager and method for enabling, optimizing and managing inter-domain video calling, telepresence and videoconferencing sessions, in exclusive video sessions, or within multi-modal communications sessions. The video session manager and method is operative for receiving and analyzing a communications session request from one or more endpoints (users); determining the viability of a communication session based on one or more attributes of the session; connecting the one or more requesting endpoints to start the session; continuously or periodically monitoring the session for problems with or changes in the session; and altering the parameters of the session in accordance with one or more predetermined policies, if a problem or change is detected, in order to maintain the viability of the session.

Video session manager and method for enabling and managing video calling and telepresence communications sessions across multiple domains

A telepresence conferencing system is disclosed in which scheduling and resource and personnel reservations may be made across various entities (i.e.; domains). Additionally, each location that is part of the telepresence conference may selectively, and independently of the other locations, designate all or selected portions of its media stream be carried over a different network from the one used to setup, control, and reserve resources for the telepresence conference.

Scheduling and resourcing allocation across multiple domains

The present invention provides a method for managing a voice call over a packet switched network, in which the voice call is rerouted when voice quality is below a predetermined level. In particular, the voice quality is determined by calculating a parameter representing the voice quality based on information regarding codec, network delay and packet loss. Preferably, R-factor and MOS is calculated based on the information obtained from Cisco CDRs during the call session.

Determining quality of voice calls over a packet network

In some embodiments, the present invention provides a distributed monitoring, evaluation and routing ('DiMER') system capable of active management of data network-based telephony. Such a system, and data network-based telephony incorporating the same, advantageously routes calls to meet call quality standards, connection speed and/or cost goals, among other targets. To meet such quality standards, the system incorporates preferences with periodically obtained call-related data and analysis, and revises call routing, as appropriate, by shifting or reallocating call traffic between available terminating gateways (based on their performance and caller preferences).

System and method for call routing through a data network

A system, method and apparatus are presented for the adaptive optimization of call quality and marginal profit in a telephony over data network, where the network contains a plurality of destinations, where calls are routable to each destination via a plurality of gateways in route to such destination, and where said gateways may serve more than one destination. The method comprises continually monitoring call traffic to each destination to first analyze whether the destination is currently volatile. If it is not, no action is taken. If it is, the method then reallocates the destination's traffic among some or all of the gateways in route to it.

Adaptive call routing system

A method and system is provided wherein routing information is obtained from previously cached information or from a gatekeeper. An originating gateway in a network receives a request for a connection and determines whether pertinent routing information is cached. If available, the cached routing is used to attempt to establish a connection. If no previously established routing is available, the originating gateway requests preferred routing from a gatekeeper, including prioritized selections of terminating gateways through which to make a connection to a designated call recipient. In a further embodiment of the invention, a process is provided to respond to a complaint regarding the quality of service. The system determines whether the reported problem is general or isolated; if it is general, alternate call routing is devised.

Call routing system and method with rule-modifying ability

A method and apparatus for optimizing routing through a data network is disclosed. Plural simulations are run on various links between network routers, and a central location may be used to compile the information from the links and calculate parameters of paths through the network. A graphical user interface to specify parameters of the simulations is also provided.
