The importance of avoiding burst/packet loss because of equipment failures, especially for critical-mission services, gives rise to a method known as 1+X path protection in optical networks. This method provides additional protection for premium (including emergency) services than the more common 1+1 path protection. In this paper, we consider a bufferless OBS/OPS network with two types of users: premium (that receive 1+X protection service) and regular (that do not receive such a service). We

We demonstrate numerically the accuracy of the approximation, and also the effect and implications of the proportion of the premium traffic as X increases.
