A method and computer program product for detecting a policy conflict in a managed system includes examining a plurality of policy rules for overlapping policy targets, in response to finding no overlapping policy targets, reporting that the policy rules do not conflict, and in response to finding overlapping policy targets, examining the plurality of policy rules for at least two rules having a same condition and a same event, and, in response to not finding at least two rules having a same condition and a same event, reporting that the policy rules do not conflict.

Efficient policy conflict detection

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 () in the set of operations associated with the contract () is mapped to a policy rule event () associated with at least one policy rule (). A second operation () in the set of operations associated with the contract () is mapped to at least one policy rule condition () associated with the policy rule (). A third operation () in the set of operations associated with the contract () is mapped to a policy rule action () associated with the policy rule (). A fourth operation () in the set of operations associated with the contract () is mapped to a policy rule condition () associated with the other policy rule ().

Automatic translation of contracts to policies in policy-based networks

A methodof and wireless communications unitfor effecting a handoff from a first Internet Protocol (IP) connectionto a second IP connectionfor a time critical communication is disclosed. The method includes communicatingbetween a first wireless stationand a second stationusing the first IP connection and a first IP addressfor the first wireless station; setting upthe second IP connection with a second IP address for the first wireless station, the first IP connection being a primary connection and the second IP connection being a secondary connection, both existing concurrently; determiningthat the second IP connection should be the primary connection; and changingthe second IP connection to the primary connection by informing the second station that the second IP address is the primary address using stream control transmission protocol (SCTP) messages, wherein the time critical communication is immediately switched over to the second IP connection.

Method and apparatus for effecting a handoff between two IP connections for time critical communications

A method of and apparatus for effecting a handoff from a first Internet Protocol (IP) connection to a second IP connection is disclosed. The method includes: communicating a packet data communication between a first station and a gateway (either acting as an application level gateway or as and endpoint for an SCTP tunnel) using the first IP connection and a first IP address for the first station, the gateway relaying the packet data communication with a second station; setting up the second IP connection with a second IP address for the first station, the first IP connection being a primary connection and the second IP connection being a secondary connection between the first station and the gateway, the first and the second IP connection existing concurrently; determining that the second IP connection should be the primary connection between the first station and the gateway; and changing the second IP connection to the primary connection by informing the gateway that the second IP address is the primary address using stream control transmission protocol (SCTP) messages, wherein the packet data communication is immediately switched over to the second IP connection.
