ABSTRACT
In general terms, overhead means anything extra that shouldn’ t be. So what is overhead in networking or how it’s affecting the entire network performance? It does not seem irrelevant for us to know something that most of us deal in everyday life knowingly or unknowingly. The technology like Ethernet that we use most to transfer data over the network is the main focus on this paper to measure the overhead. We all know the bandwidth we get from ISP, that’s what we paid for, but are we fully able to use the full bandwidth? No, we can’t but why? This paper will give the general idea of some networking terms along with details about network overhead. It also will answer those questions those I initiated here by providing some analysis and experiments. This paper may help us to understand some critical factors that need to be accounted during network design period for best optimal network performances.
INTRODUCTION
Overhead is an important term in networking for the design, implementation, and performance issues. Understanding overhead properly is basic to understanding the methodology employed by various technologies to get information from one place to another and the cost involved. According to PC Magazine, overhead is the amount of processing or transmitting time used by the system software, database manager or network protocols that trans mits additional codes in order to control and manage the data transfer over the network (PC Magazine). Keep in mind, when assessing the performance of networks there is always a difference between theoretical speed ratings, and real world throughput. If we are able to design the seamless network, then the difference should be relatively small but still
