9 Questions
Which approach to implementing routing functionality has been the traditional approach adopted by routing vendors in their products?
Each router having a routing component that communicates with the routing component of other routers
What is the remote controller in the alternative approach shown in Figure 4.3 responsible for?
Computing and distributing the forwarding tables to be used by each and every router
What is software-defined networking (SDN)?
A network where the controller that computes forwarding tables and interacts with routers is implemented in software
Which of the following is a key difference between the routing functionality approach shown in Figure 4.2 and the approach shown in Figure 4.3?
Figure 4.2 has each router communicating with the routing component of other routers, while Figure 4.3 has a physically separate, remote controller computing and distributing forwarding tables.
What is the control-plane approach shown in Figure 4.3 at the heart of?
Software-defined networking (SDN).
What is a benefit of implementing a remote controller in the control-plane approach shown in Figure 4.3?
It can be implemented in a remote data center with high reliability and redundancy.
Which term is used to refer to a device that transfers a packet from input link interface to output link interface, according to values in a packet’s header fields?
Packet switch
In which section of the chapter will you find information about the internal hardware operations of a router?
Section 4.2
What is the difference between link-layer switches and routers?
Link-layer switches base their forwarding decision on values in the fields of the link-layer frame, while routers base their forwarding decision on header field values in the network-layer datagram.
