Nagle's algorithm
A.What is the purpose of Nagle's algorithm?
B.Do delayed acknowledgements and Nagle's algorithm interfere?
C. Are there situations where Nagle's algorithm is not desirable?
D. Can you disable Nagle's algorithm on your machine? Describe the operating system you
are using to answer this question.
Homework Answers
A.
1. The Nagle's algorithm was created by John Nagle
2. It helps in improving the efficiency of TCP/IP network by solving the congestion created by small packets on the network
3. The algorithm detects small sized packets over the network and accumulates them into large TCP packets.This method is called nagling.
4. It efficiently uses the bandwidth of the network.
5. Nagle's Algorithm was published in RFC 896 in 1984
B.
If the Client uses a technique of Delayed Acknowledgement and send s a request to Server.The Server sends a full-sized packet and a small sized packet.Then the Client can delay the acknowledgement as it has to send acknowledgement for two full-sized packet .At the server's side Nagle's algorithm doesnot allow the server to send data unless acknowledgement is received .Thus this creates a deadlock scenario.
C.The situation where Nagle's Algorithm is not desirable :
1. Nagle's Algorithm is only suitable for TCP,other protocols don't support it.
2. It is not benefited for fast transmission of data
D.
To disable,
1. type in RUN Regedit
2.open Registry settings.
3. Select from the drop down menu
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interface.
4.Select the IP Address of the label DhcpIPAddress
5.To check the IP Address use WIN KEY + X > Control Panel > Network and Internet > Network and Sharing Center > Connections > Details > IPv4 Address.
6.Right-click New > DWORD (32-bit) Value.
7.This will , create two DWORD Values; name one TcpAckFrequency and the other TCPNoDelay.
8.Finally, double-click on each one and set their parameters to 1.
This will disable the Nagle's algorithm

Please help me with this answer. Performance Comparison for Dijkstra Algorithm and Bellman-Ford Algorithm Problem Description The shortest path problem is one of most important problems in graph theory and computer science in general. Shortest path problem is one of typical optimization problems. Given a graph G = (V,E), the goal is to nd a minimum cost path from s → t, s,t ∈ V . This variant is called one-to-one shortest path problem. Other variants are one-to-all (compute shortest...
