Which among the following is a disadvantage of the signaling pipe?(a)

1.	Which among the following is a disadvantage of the signaling pipe?(a) Lack of instant signaling(b) Separate headers for non-adjacent layers(c) Unreliable delivery of information(d) Generation of interface between non-adjacent layersThe question was asked during an interview.This is a very interesting question from Next Generation Wireless Network topic in chapter Next Generation Wireless Network of Cognitive Radio
Answer» Correct OPTION is (a) Lack of instant signaling Best EXPLANATION: Interlayer signaling allows signaling information to pass from layer to layer along with packet flow. The processing PATH in the protocol stack may pass from top to bottom or from bottom to top. This is not suitable for cross-layer IMPLEMENTATION SINCE it requires instant signaling.
