It is disclosed a method for protecting a computer network against a failure. The method comprises: identifying a number of possible failures which might occur within the computer network, the number of possible failures comprising at least one possible failure; and, based on detected availability of resources in the computer network, determining a protection state of the computer network allowing to circumvent the possible failure and dynamically updating the determined protection state based on changes of the detected availability. The method further comprises, upon occurrence of the failure, if the occurred failure corresponds to the possible failure, bringing the computer network into an operative protection state corresponding to the determined and dynamically updated protection state.

Protection against a failure in a computer network

A system for error correction in digital transmissions using the so-called Reed Solomon coding/decoding techniques. At the reception side, the received data stream is processed using a new decoding algorithm. Also, with the described decoding algorithm, error correction is implemented using more simplified equipment than that found in other types of conventional error correction systems. The components making up the error correction system of the invention basically consist of: (1) a central timing unit, (2) a preset unit and (3) at least one Reed Solomon coding/decoding circuit operating in accordance with the proposed algorithm.

A system for structuring information outputted at a variable bit rate from a video signal encoder and for organizing the information into information units or packets. The information packets are compatible for transmission and processing by packet transmission networks such as asynchronous transfer mode (ATM), capable of sending transmission data streams at variable speed. In a preferred embodiment, the system uses an encoder that comprises video units. Each video unit contains information classified into three distinct classes. Each video unit is associated with a video packet comprising a header and a body. Each of the three distinct classes of information associated with a video unit uses a different technique for tho providing protection of that information against transmission errors and/or information packet loss.
