Expert Solution & Answer
Chapter 13.8, Problem 13.8.2CP
Explanation of Solution
Abstract class:
An abstract class is a class which may or may not include abstract methods and cannot be instantiated but rather can be sub classed.
Legal abstract class:
The conditions for a class to be considered as legal abstract class are mentioned below:
- If a class includes abstract methods, then the class must be declared as abstract.
- The abstract method that is declared within the abstract class must be declared without braces and followed by a semicolon.
Interface:
Interface is a reference type in Java, which contains a collection of abstract methods.
An interface needs to the follow certain conditions such as:
- One cannot instantiate an interface.
- Interfaces do not contain any constructors.
- All methods present in the interface are abstracts.
- An interface does not contain any instance field.
- An interface cannot be extended by a class.
Similarities between abstract classes and interfaces:
Some of the similarities between abstract classes and interfaces are mentioned below:
- One cannot create objects for both abstract classes and interfaces.
- All the abstract methods must be overridden by the sub class in both interfaces and interfaces.
- One can create reference variables for both abstract classes and interfaces...

Create an original network topology consisting of at least seven routers and twelve links, assigning
arbitrary positive weights to each link. Using this topology, apply Dijkstra's Link-State Algorithm
to compute the shortest paths from a source router of your choice to all other routers in the network.
Your topology must be entirely your own design and should not resemble any examples from the
textbook, lecture slides, or other students' work. Al-generated topologies are not permitted. Create
a PowerPoint presentation that follows the format and style of slides 11 to 23 from Lecture Slide
Set 06 (LS06). You should copy those slides and make any necessary changes, additions, or
deletions to reflect your own topology, shortest-path calculations, and update tables. Do not alter
the original slide style, layout, or formatting.

- 2) Assume a local area network has four host computers (h1, h2, h3 & h4) and they are connected to the internet through a NAT router (s1). The host computers use private IP address space: 192.168.2/24. Each host is trying to establish 2 TCP connections to a remote webserver through the NAT router. The IP address of the webserver is: 130.12.11.9. Now do the following: 1 a. Assign IP addresses to the interfaces of the hosts and the router. For the router, assign arbitrary addresses. List these addresses. b. Now create a NAT translation table as taught in the class for all TCP connections. Assign arbitrary port numbers as required.arrow_forward1) Consider the following network.
