In data networks, response time is the amount of time when an individual user enters a commands or press a particular key stock on their work station and when that particular command get executed. You need to minimize the response time for better network performance. You can accomplish low response time by using different mechanisms. The selected protocol (such as Frame Relay or ATM, EIGRP or OSPF) will greatly affect the data in the network transmission delay time. These include the process delay time (host receives the data packet and obtain information), queuing delay (when there is the additional information packet), the transmission delay, the transmission delay, depending on the physical media and distance). Additional delay may results damage and loss of the packet’s information which reduce the quality and you may need to re-transmit this data. For satellite network transmission delay is a major problem.
