Abstract: A system, method and computer program product are provided for dynamic adaptation of a system in accordance with a contract with criteria associated therewith. During operation, an interaction between a plurality of components of a system is governed utilizing the criteria of the contract. Further, it is determined whether the interaction between the components of the system meets the criteria of the contract. Upon the criteria of the contract not being met, the interaction between the components of the system is adapted to conform to the criteria.

Abstract: A system, method and computer program product are provided for managing the use of a plurality of security service providers during network communication. A first security service provider is utilized for affording secure communication between applications using a network. During operation, the system is monitored for events relating to the secure communication between the applications. Upon the detection of an event, a second security service provider is utilized for affording secure communication between the applications using the network.

Abstract: A two way digital communication arrangement utilizes a CATV system to provide bidirectional data transport service between any two points within the CATV system. The headend receives an upstream message and selectively rebroadcasts such message on the downstream portion of the spectrum. System intelligence is thus distributed throughout the system as server and subscriber nodes can be located anywhere in the CATV network. In order to obtain access to the CATV communication resources, user equipment at each node must attach a frame verifier (FV) code to each respective message. The headend examines the FV and permits rebroadcast of messages only if the FV code indicates that the user is authorized.
