Abstract:
As routers ( 15 ) are added to an existing network ( 41 ), links serviced by such routers that lack a pre-existing corresponding address prefix may occur. The router ( 15 ) can contact a prefix server ( 14 ) and engage in a process to automatically receive a new address prefix from the prefix server ( 14 ) to use with such links. In one embodiment, the prefix server ( 14 ) can automatically assign such address prefixes to form or maintain an aggregation of routes to facilitate the efficient operation of routers within the network and overall network growth.
Abstract:
A router 104 can automatically self assess which of its interfaces are coupled to an active communication link and then identify which interface needs a new network address prefix. Existing and available network address prefixes can be utilized to automatically self configure interfaces as appropriate. The interfaces and their corresponding communication links that require a new address prefix can be flagged for subsequent attention.
Abstract:
A method and system for supporting an emergency call is disclosed. The method includes initiating (302) an emergency call through an Internet Protocol (IP) based system (108). The method further includes receiving (304) authorization for restricted access to the resources of the IP based system, only for the purpose of making the emergency call.
Abstract:
A system, method, and information processing system manage a network. At least one contract including one or more components is received at a network that uses a component based architecture. A first operation (422) in the set of operations associated with the contract (114) is mapped to a policy rule event (424) associated with at least one policy rule (116). A second operation (426) in the set of operations associated with the contract (114) is mapped to at least one policy rule condition (428) associated with the policy rule (116). A third operation (430) in the set of operations associated with the contract (116) is mapped to a policy rule action (432) associated with the policy rule (116). A fourth operation (440) in the set of operations associated with the contract (116) is mapped to a policy rule condition (442) associated with the other policy rule (420).
Abstract:
A method and system for evaluating performance of a policy rule (101 ) includes a memory (406) and processor (404) adapted for accessing at least one policy rule (101 ) having associated with it at least one policy event (102), at least one policy action (104), and at least one policy condition (103). Next, the policy rule (101 ) is associated with at least one policy evaluation event (105), at least one policy evaluation condition (106), and at least one policy evaluation action (107), wherein the policy evaluation event (105) is independent of the policy event (102) which triggers the policy rule (101 ). Performance of the policy rule (101 ) is then assessed by utilizing the policy evaluation condition (106) and the policy evaluation action (107).
