Unformatted text preview: Problem 3 Consider an eight-node (2, 2) ShuﬄeNet. Calculate the average delay for a uniform traﬃc matrix (the arrival rate for each source-destination pair is λ packets per second). Assume that the service time for a packet at a node is exponentially distributed with mean 1/ μ . Assume shortest path routing. Problem 4 Consider a ( p,k ) = (3 , 2) Shuﬄe Net. 1. Draw the interconnections between the nodes. 2. How many wavelengths are needed in this network in the dedicated wavelength operation and the shared channel operation. 3. Find the average number of hops in the dedicated wavelength operation. 4. Let’s assume that each wavelength carries a bit rate of 1 Gbps, ﬁnd the total network capacity in the dedicated wavelength operation. 1...
