Chapter Questions
Read about Ethernet switches and find the size of TCAM used.
If your site employs MPLS, make a list of the classification rules that are used and state the purpose of each.
If a Layer 2 switch has $P$ ports that connect to computers, what is the maximum number of MAC destination addresses the switch needs to place in its classifier? Be careful because the answer is not obvious.
Write classification rules that send all VoIP traffic down MPLS path 1, web traffic down MPLS path 2, ssh traffic down MPLS path 3, and all other traffic down MPLS path 4.
A manager wants to send all multicast traffic down MPLS path 17 and all other traffic down MPLS path 18. What is the simplest set of classification rules that can be used?
Does your answer to the previous question change if a site uses both IPv4 and IPv6?
The text asserts that classification is needed to process packets that arrive at $10 \mathrm{Gbps}$ because an Ethernet frame only takes 1.2 microseconds to arrive. How many bits are in the payload of such a frame?
In the previous problem, how many instructions can a high-speed processor execute in 1.2 microseconds?
On most networks, the smallest packets contain a TCP ACK traveling in an IPv4 datagram. How long does it take for such a frame to arrive?
