Textbook Question
Chapter 6, Problem R1RQ
Consider the transportation analogy in Section 6.1.1. If the passenger is analagous to a datagram, what is analogous to the link layer frame?
Expert Solution & Answer
Program Plan Intro
Link Layer:
- In the OSI (Open Systems Interconnection) model, data link layer is the 2nd layer. This layer is used to transfer data between neighboring network nodes on a Wide Area Network or on the same Local Area Network.
- This layer uses error detection bits and it corrects the errors.
Explanation of Solution
Transportation analogy:
In the section 6.1.1, the travel agent plans a trip for tourists from different places.
- The travel agent decides the convenient plans for the tourists and the agent makes three reservations.
- The three reservation trips are direct between two adjacent locations and also they contain different transportation modes.
- Here, if the passengers are analogous to the datagram, then the transportation modes are analogous to the link layer frame.
Therefore, the transportation modes are analogous to link layer frame.

For simplification, only consider cutting the rope at an integer position by the meter metric. Each cut has a cost associated with it, c(m), which is the cost of cutting the rope at position m. (You can call c(m) at any time to return the cost value.) The goal is to cut the rope into k smaller pieces, minimizing the total cost of cutting. B Provide the pseudo-code of your dynamic programming algorithm f(n,k) that will return the minimum cost of cutting the rope of length n into k pieces. Briefly explain your algorithm.
