    摘要: Methods and apparatus for allowing a traffic level switch associated with an automatic protection switching (APS) topology to occur transparently and without reconverging routing are described. According to one aspect of the present invention, a method for providing protection switching configuration information associated with a router arrangement to includes identifying a first interface and a second interface of the router arrangement as an APS group. The method also includes providing information regarding the APS group to a process that implements a routing protocol. Providing the information regarding the group includes identifying the first interface as a primary interface and identifying the second interface as a backup interface that is arranged to protect the primary interface.

    摘要: A system and method for shattering a launch vehicle into relatively small pieces are described. The launch vehicle includes at least one solid fuel rocket motor having a propellant disposed about a combustion chamber within a rocket motor case. Each rocket motor also includes at least one motor igniter to ignite the propellant and at least one explosive charge adjacent the rocket motor case. A firing unit is capable of generating a motor ignition signal and a charge explosion signal. A first propagator carries the motor ignition signal to the motor igniter so the signal arrives after a propagation time T.sub.ignition and causes ignition of the previously unignited rocket motor. A second propagator carries the charge explosion signal to the explosive charge so the signal arrives after a propagation time T.sub.explosion and causes an explosion against the rocket motor case. The time T.sub.explosion is greater than the time T.sub.ignition by a pressurization time T.sub.pressurization that is sufficient to allow pressurization of the combustion chamber before actuation of the explosive charge. Pressurization of the combustion chamber exerts forces on the rocket motor case which act in combination with the subsequent force from the explosion to shatter both the case and the propellant much more effectively than conventional destruction systems.
