Why is the problem being solved?

 The Routing Techniques do solve the problems in modern times. These are supposed to be the architectures of the network, which are used to rectify the problems and issues by all the time. One can utilize all of them to resolve their matters and issues in all means. We can all use these architects for our further usages as well.

Q no 2: Why is it interesting, relevant, and or important?                                                                             

 The Routing Techniques are really interesting in true means as they are used to architect commercial networks so far. They are quite relevant to the modern time's usages as Routing algorithms all tend to fall in the shortest path class. These are so important due to their shortest version of usage.

Q no 3: what approaches existed at the time that this work was done?

Answer: when this work was being done. The approaches being used were TYMNET, ARPANET, and TRANSPAC. These approaches really revolutionized the very realm of routing techniques so far.

Q no 4: Why existing approaches were not adequate? 

Before the very usage of the approaches named TYMNET, ARPANET, and TRANSPAC, the techniques being used were not adequate enough to make the operations of the network run smoothly. That is why; new techniques were used to make the whole work run smoothly in all means. These approaches have really revolutionized the realm of networking.

Q no 5: What is the proposed approach, and how does it compare to earlier approaches?

The earlier approaches or techniques were not designed for the shortest path to operate. Whereas the shortest path algorithms are the one appropriate for the centralized computation, while the others are for distributed computation actually. So, the real propose is to smooth the system altogether for the benefit of all the computer users in all means.

Q no 6: What are the main strengths and weaknesses of the paper/proposed approach?

Usage of routing procedures like TYMNET, ARPANET, and TRANSPAC is the actual strength area of the paper. Here algorithm usage also facilitates the computing system so far. Whereas the weaknesses are we all still need to achieve many more targets in the computing world so far.
