Network Measures

Performance can improved only if we know how to gauge it. There are many things to consider that might affect a transmission. Here we will uncover some of the key factors.

Definitions

Defining some basic terminologies.

Bit and Byte

Bit is lowest denominator which is either 0 or 1 denoting on and off. Byte formed by 8 bits.

Bandwidth

It is the number of bits that can be transmitted over a network in a certain period of time. Example units is Mbps, Gbps, Kbps, etc.

Throughput

It is the measurement of the actual bits transmitted over the network in a certain period of time. Example units is Mbps, Gbps, Kbps, etc.

Propagation

It is the time taken by light to travel from source to destination. Example unit is ms.

Transmit

It is the time required to transmit a number of bits over a network. Example unit is ms.

Latency

It is the time required by a message to reach destination form source. Example unit is ms.

Round-Trip Time

It is the total time taken to transmit a request from source to destination and back to the source with a response. Example unit is ms.

Transfer Time

It is the sum of RTT and Transmit. Example unit is ms.
