An approach for efficient failover detection includes detecting an attempt by a first server to transition from a standby mode to an active mode, diagnosing a loss of connectivity to the first server in a control plane as a cause of the attempt, and transitioning to a standby mode based on the diagnosed cause of the attempt.

Method and apparatus for failover detection and recovery using gratuitous address resolution messages

An approach for providing value-based resource management and admission control is described. A value-based platform may receive a request from a user or a service provider to access an asset, a service, or a combination thereof. The value-based platform may further apply a policy rule to account information associated with the user to determine a user value score. The value-based platform may also generate prioritization information for admitting the user to the asset, the service, or a combination thereof based on the user value score.

Method and apparatus for providing value-based resource management and admission control

A network device implements resource admission policy management related to controlling the denial or grant of a delivery of a network service to a customer device. The network device receives a notification related to a change in network topology or network capacity of a network that delivers the network service. The network device identifies changes in the network topology or the network capacity based on the notification, and applies resource admission control to deny or grant the customer device access, to resources of the network to receive delivery of the network service, based on the identified changes in the network topology and/or the network capacity.

Network service admission control using dynamic network topology and capacity updates

Methods and systems are described for performing alternate routing of communications in a network. The system initiates a communication from an origination endpoint in a packet-switched network, such as a VOIP network, to a destination endpoint, and determining, according to selection criteria, whether to route the communication to the destination endpoint using at least a second circuit-switched network, such as the PSTN.

System and method for providing alternate routing in a network

A system including a location server configured to receive registration data from an IP device and a location database configured to store location information of the IP device, wherein the location server queries the location database to determine whether the registration data matches the location information stored at the location database.

E911 location server

A method for performing alternate and therefore least cost routing in distributed H.323 Voice over IP (VoIP) networks is provided. With this method, the VoIP network consists of a hierarchy of gatekeeper (GK) functions to provide alternate routing, network element redundancy, and scalability. The alternate routing function is performed by a directory gatekeeper with route selection advancing from a first route to a second route by either of two conditions: (1) there are no resources available to terminate the call in the first zone; and (2) a lack of response to the directory GK request for such resources.

Alternate routing of voice communication in a packet-based network

An apparatus for providing emergency service validation may include a processor. The processor may be configured to receiving a message associated with a registration event of a device to a communication session. The message may include a parameter having information indicative of a location of the device at a time of the registration. The processor may also be configured to determine whether the location of the device at the time of the registration corresponds to a location where an emergency service dispatch is supportable.

Method, apparatus and computer program product for providing emergency service validation

Enhanced call management services to users receiving incoming calls on extensions on a private branch exchange (PBX) is provided by an application server configured to provide call management services to at least one of the users and a protocol proxy configured to receive call information from the PBX according to a protocol for establishing call sessions. The application server is further configured to receive the call information from the protocol proxy.

PBX call management

A resource manager permits a first user to use a first bandwidth of a shared pool of bandwidth for receiving a first media stream, where the shared pool of bandwidth comprises a maximum amount of available bandwidth. The resource manager receives a request from a second user to use a second bandwidth of the shared pool of bandwidth for receiving a second media stream, and determines whether it is permissible to decrease the quality of the first media stream or the second media stream to reduce the first bandwidth or the second bandwidth such that the second bandwidth combined with the first bandwidth does not exceed the maximum amount of available bandwidth of the pool of bandwidth, where determining whether it is permissible to decrease the quality of the first media stream or the second media stream includes one of: signaling the first user to determine if the first user approves decreasing the quality of the first media stream, or signaling the second user to determine if the second user approves decreasing the quality of the second media stream. The resource manager further decreases the quality of the first media stream or the second media stream based on the permissibility determination.

Adaptive bandwidth resource management for media streams

A system including a first network configured to receive IP device data from an IP device and to provide one or more IP addresses of the IP device based on the IP device data; a second network comprising: a second network location database configured to store physical location information, and a second network location server configured to receive the one or more IP addresses of the IP device from the first network, and query the second network location database to determine physical location information of the IP device based on the one or more IP addresses.

Mapping of IP phones for E911

A system including an IP device configured to provide registration data, a Service Bureau configured to store location information of the IP device and provide routing data based on location information of the IP device, location server configured to receive registration data from the IP device, and location database configured to store location information of the IP device, wherein the location server queries the location database to determine whether the registration data matches the location information stored at the location database.
