Abstract: A method and system for protecting virtual traffic travelling through a protected domain having of a bridge node connected to a selector node in working and protection paths. Upon detecting failure of the traffic channels in the working path, the detecting node transmits failure information to the selector node along the traffic channels and along an alarm channel in the working path. The selector node initiates protection switching of the traffic channels as soon as failure information is received along the alarm channel. The alarm channel has a sufficiently high priority relative to the traffic channels that protection switching is initiated before failure information is received along the traffic channels. Thus, the selector node can initiate protection switching before receiving alarm cells on traffic channels, which significantly reduces the time during which the traffic channels contain alarm cells. Advantageously, the invention helps prevent premature termination of the end-to-end traffic connection.

Abstract: A conventional apparatus for dispensing ice-cream of the type having a lever-operated vertically-disposed and downwardly-directed dispensing nozzle, is combined with one or more syrup applicators, each having lever-operated dispensing nozzles disposed below and substantially normal to the ice-cream nozzle. After or during dispensing of ice-cream into a cone, one or more selected syrups are applied to the ice-cream discharged in the cone, while the latter is rotated by hand.
