This paper introduces an implementation of the network coding-based generalized 1+N protection technique presented earlier by the author in [1] to protect against single link failures. Instead of using two protection circuits for a group of connections which are to be protected together as in [1], only one protection circuit is used, which takes the form of a tree. The protection circuit carries linear combinations of the data units originally transmitted on the working circuits, and these… CONTINUE READING
