Explanation of Solution

Difference between main memory and auxiliary memory:

 

Main memoryAuxiliary memory
It is directly accessible by the CPU.It is not directly accessible by CPU
It contains the data to be processed by the computer and holds the result of the calculations.Data which needs to be stored permanently is kept in the secondary memory
It is volatile in nature.Auxiliary memory is non-volatile.
It could be accessed by the data bus.It could be accessed by the input-output channels.
Data could be accessed in a faster rate.Data accessed by the secondary memory is slower.
It is made up of semiconductorsIt is made of magnetic and optical material.

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.
1) Consider the following network. Host h6 10.3.0.6 Host h5 10.3.0.5 Host h1 10.1.0.1 OpenFlow controller m 2 3 4 Host h4 10.2.0.4 Host h2 10.1.0.2 Host h3 10.2.0.3 The desired forwarding behavior for the datagrams arriving at s2 is as follows: a) any datagrams arriving on input port 1 from hosts h5 or h6 that are destined to hosts h1 or h2 should be forwarded over output port 2; b) any datagrams arriving on input port 2 from hosts h1 or h2 that are destined to hosts h5 or h6 should be forwarded over output port 1; c) any arriving datagrams on input ports 1 or 2 and destined to hosts h3 or h4 should be delivered to the host specified; d) hosts h3 and h4 should be able to send datagrams to each other. Create a flow table for s2 that implement these forwarding behaviors. Your table should have 2 columns one for match and the other for actions, as taught in the class.
