Question

Which among the following is false about the CLASS approach?

(a) Eliminates insertion of signaling information

(b) Supports only unidirectional communication

(c) Reduce overhead

(d) Eliminate interception of packet at non-destination layer

This question was addressed to me by my school principal while I was bunking the class.

This is a very interesting question from Next Generation Wireless Network topic in division Next Generation Wireless Network of Cognitive Radio

Answer 1

Correct choice is (b) Supports only unidirectional communication

For explanation I would say: CLASS eliminates interception of packet at non-destination layer, reduces processing overhead, eliminates insertion of signaling information, and supports bidirectional communication. Signaling message typically includes the Internet Control Message Protocol.
