Computer Networks - Internet Architecture & Application Layer Please answer the question Someone suggested to use a local file called hosts.txt on each machine instead of DNS. Discuss the advantages (at least 2) and disadvantages (at least 2) of such suggestion. What is ‘saw-tooth’ behavior in TCP, and what is causing it?
The industry currently favors connection-based protocols, so please provide a succinct explanation of the advantages and disadvantages of connectionless protocols.
2. Subnetting a subnet or using variable-length subnet mask (VLSM) was designed to maximize addressing efficiency. You are required to subnet, based on the number of hosts, including router interface and WAN interface and WAN connections for the following scenario: •Toronto: 60 host addresses •Montreal: 28 host addresses •Ottawa: 12 host addresses •Vancouver: 12 host addresses •WAN1: 2 host addresses •WAN2: 2 host addresses •WAN3: 2 host addresses Using the given address block of 192.168.15.0/24, you can design an address scheme for the network to meet its requirements and save potential addresses. The data for Toronto is given to help you to fill the remaining all other columns. Name Toronto Montreal Ottawa Vancouver WAN1 WAN2 WAN3 Required no of addresses 60 28 12 12 ~~ 2 2 2 Subnet Address 192.168.15.0 Address Range .1 - .62 Broadcast Address .63 Network/ Prefix 192.168.15.0 /26 19
Comparing the features of connectionless protocols with those of connection-based protocols would be a fascinating exercise.
What are the advantages and disadvantages of connectionless protocols in comparison to connection-based protocols?
One helpful exercise is to weigh the merits of connection-based versus connectionless protocols against one another.
Please describe the pros and cons of connectionless protocols as a potential alternative to connection-based protocols.
4. The original HTTP protocol used TCP/IP as the underlying protocol. For each page, graphic, or applet, a separate TCP connection was constructed, used, and terminated. This caused several problems: one referred to as the elephant and mice problem and two aspects of connection overhead. Describe both problems. Why were separate connections used? Would UDP rather than TCP be a good alternative? What solution would you propose to these problems to improve HTTP performance?
The benefits and drawbacks of connectionless protocols must be weighed against those of connection-based protocols.
It is wise to weigh the advantages and disadvantages of connectionless protocols in relation to connection-based protocols, and the other way around.
TCP sockets handle data sent as a byte stream, but UDP sockets are aware of message boundaries.What are the advantages and disadvantages of a byte-oriented API versus an AP that recognises and preserves application-defined message boundaries?
Think about the advantages and disadvantages of connectionless protocols in comparison to those of connection-based protocols.
