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.

2. Latency is a problem for interactive communication viasattelite. Calculate the orbital altitude and round-trip delaytime between two stations on the ground communicating via a geostationary satellite. Assume the radius of the orbitis 42,164 kilometers and the radius of the earth is 6,378kilometers.
3. MTOSI and OASIS are standards that enable integration of distributed applications using SOA, discuss both of these standards.
4. Broadband access technology is still an emerging field. There are four modes of access using four different technologies. Specify these modes.
5. What is JINI technology?
