1. Exercise 10 of Chapter 12 on page 505: The network shown in Figure 12.44 on page
506 is an MPLS network with all routers configured as Label-Switching Routers
(LSRs). The paths (LSPs) are determined using TE (Traffic Engineering). The
address of each router is x.x.x.x where x is the router number, for example, 220.127.116.11.
Explain your reasoning and fill in the R2 routing table:
a. for paths with no tunnels and
b. for paths with tunnels T1 and T2.
2. Exercise 6 of Chapter 13 on page 553: Cable modems on the coaxial part of the
topology of an HFC configuration shown in Figure 13.3 on page 510 are a tree
structure. Cable modems with Ethernet stations resemble an Ethernet LAN.
Contrast an HFC coaxial broadband LAN with a regular Ethernet LAN on: (a)
topology, (b) downstream protocol, and (c) upstream protocol.
(a) What MIB table would you use to measure the QoS of service flow in a fixed wireless system
between the base station and the subscriber station?
(b) Define latency and jitter for service flow in a fixed wireless system
(c) Write the specific managed objects associated with latency and jitter
