Abstract: A mechanism is provided for recovering from a catastrophic failure that results in a large number of user endpoints attempting to come on line simultaneously after an NGN is restored. In an enhanced DNS load balancer, DNS queries from the user end points relating to a particular NGN edge device are selectively dropped if a rate of queries for the particular edge device suddenly increases or exceeds a threshold. The query dropping may also be based in part on the class of service assigned to the user endpoint.

Abstract: Methods, systems, and computer-readable media for ensuring data integrity during data synchronization are provided. According to one method, a number of originating requests from a plurality of user endpoints are monitored across a network. A determination is made whether the number of originating requests is below a first threshold. Responsive to determining that the number of originating requests is below the first threshold, probe messages are transmitted to at least a portion of the plurality of user endpoints across the network. A number of the user endpoints that return probe replies in response to the probe messages are monitored. A determination is made whether the number of the user endpoints is below a second threshold. Responsive to determining that the number of the user endpoints is below the second threshold, a report is made to a database that the network is unavailable, thereby causing the database to stop updating time stamps.

Abstract: System(s) and method(s) are provided for regulating interaction amongst an application layer and a control layer in a packet-based core network. A data structure is provisioned in a centralized repository; the data structure includes (i) at least one procedure for regulating interaction amongst a session control component within the control layer and application server within the application layer, and (ii) an identification (ID) field attribute that uniquely identifies the data structure. To regulate such interaction, the session control component acquires a set of provisioned data structures; acquisition is automatic and can be dictated, in part, by generation of a data structure, or modification of an existing data structure or an ID field attribute. Based at least on an ID field attribute retained in a subscriber service profile, the session control component references a data structure identified by the ID field attribute and implements one or more procedures retained in such data structure. Implementation of the one or more procedure regulates the interaction between the session control component and the application server.

Abstract: A system and methodology that facilitates improving performance of a Home Subscriber Server (HSS) during overload conditions, by embedding a unique Application Session Identifier (app session ID) within multiple requests associated with a single call processing session is provided. Moreover, the system includes an overload protection component that identifies whether an incoming request is associated with previously processed requests based in part of the app session ID embedded within the incoming request. When the HSS is overloaded, the incoming requests that initiate a new call processing session and are not associated with previously processed requests are rejected/dropped before incoming requests that are associated with requests that have been previously processed.

Abstract: A mechanism controls global synchronization, or registration floods, that may result when a large number of endpoints in a Voice over Internet Protocol (VoIP) network such as an Internet Protocol Multimedia Subsystem (IMS) come online simultaneously after a catastrophic failure. The mechanism allows the Domain Name System (DNS) infrastructure to efficiently control the overload condition by registering user end points with backup border elements, and by staggering and by randomizing the time-to-live (TTL) parameter in registrations with backup border elements.
