  1. The network shown in the figure below is an MPLS network with all routers configured as Label Switching Routers(LSRs). The path (LSPs) are determined using TE (Traffic Engineering). Fill in the R2 routing table (a) for paths with no tunnels and (b) for paths with tunnels T1 and T2. The address of each router is x.x.x.x where x is the router number, e.g., 1.1.1.1.

  1. Latency is a problem for interactive communication via sattelite. Calculate the orbital altitude and round-trip delay time between two stations on the ground communicating via a geostationary satellite. Assume the radius of the orbit is 42,164 kilometers and the radius of the earth is 6,378kilometers.
