摘要： Disclosed are techniques for optimization of media flows within a provider network. The provider network comprises a plurality of sites, each site having one or more media servers capable of supporting a media session with a user endpoint device. The provider network further includes a media server director (MSD) that receives registration information identifying one or more user endpoint devices that have registered with a particular site. Using this registration information, as well as predetermined preference policies, the MSD prepares a preference order for the media servers of the provider network for user endpoint devices associated with the site. When an application server signals an intent to establish a media session with a user endpoint device of the site, the MSD selects a media server based on the preference order and provides an indicator of the selected media server. The application server can then contact the selected media server identified by the indicator to establish and support a media session with the user endpoint device.

摘要： An apparatus and method are disclosed for processing a communication request from a roaming VoIP terminal. An apparatus that incorporates teachings of the present disclosure may include, for example, a network proxy having a controller that manages a communications interface in a communication system. The controller can be programmed to receive from a Voice over IP (VoIP) terminal a request to communicate with a destination point, wherein the request comprises an identification (ID) of the destination point, an ID of the VoIP terminal, and a media access control (MAC) address of a gateway providing the VoIP terminal communication access to the network proxy, and determine from the MAC address of the gateway and the ID of the VoIP terminal whether the VoIP terminal is roaming outside of a home network. Additional embodiments are disclosed.

摘要： A method and apparatus for controlling a call volume for an office that serves as a protecting site for another office in a packet network are disclosed. For example, the method collects one or more customer registration counts from one or more session border controllers located in a first office, determines if the one or more customer registration counts have reached or exceeded a threshold. The method directs all of said one or more session border controllers located in said first office to enact one or more throttling rules if the one or more customer registration counts have reached or exceeded the threshold.

摘要： A method and apparatus for managing an overload condition in a network are disclosed. For example, the method monitors the network for a traffic overload condition, and determines whether a more severe traffic overload condition or a less severe traffic overload condition is detected by using a network monitor and controller. The method then selects using a network monitor and controller agent in response to a command from the network monitor and controller, a different bandwidth preservation scheme if the more severe traffic overload condition or the less severe traffic overload condition is detected, wherein the different bandwidth preservation scheme is based on a selection of a codec type and is applied to a portion of the traffic.

摘要： According to one method for preserving stable calls during failover, during a dialog between two user endpoints, a determination is made whether a standby call processor has become operational, such as when a corresponding primary call processor is in fault. Responsive to determining that the standby call processor has become operational, a signaling protocol message is received from a requester. A determination is made whether the message includes an in-dialog signaling protocol request. Responsive to determining that the message includes the in-dialog request, a determination is made whether a call state associated with the dialog is found in memory. Responsive to determining that the call state associated with the dialog is not found in memory, a non-call terminating error response is made responding to the in-dialog request. The non-call terminating error response may cause the requester to terminate the in-dialog request but not terminate the dialog.
