Latency in optical fiber is largely a function of the speed of light. This would equate to a latency of 3.33 μs for every kilometer of path length. The index of refraction of most fiber optic cables is about 1.5, meaning that light travels about 1.5 times as fast in a vacuum as it does in the cable. This works out to about 5.0 μs of latency ...
All these models had one thing in common: they all predicted very short average path length. [1] The average path length depends on the system size but does not change drastically with it. Small world network theory predicts that the average path length changes proportionally to log n, where n is the number of nodes in the network.
A telecom satellite in geosynchronous orbit imposes a path length of at least 71000 km between transmitter and receiver. [2] which means a minimum delay between message request and message receipt, or latency of 473 ms. This delay can be very noticeable and affects satellite phone service regardless of available throughput capacity.
If the sent data packet as well as the response packet have the same length, the roundtrip time can be expressed as: Roundtrip time = 2 × Packet delivery time + processing delay. In case of only one physical link, the above expression corresponds to: Link roundtrip time = 2 × packet transmission time + 2 × propagation delay + processing delay
It specifies the latency for a bit of data to travel across the network from one communication endpoint to another. [1] [2]: 5 It is typically measured in multiples or fractions of a second. Delay may differ slightly, depending on the location of the specific pair of communicating endpoints.
RTT is a measure of the amount of time taken for an entire message to be sent to a destination and for a reply to be sent back to the sender. The time to send the message to the destination in its entirety is known as the network latency, and thus RTT is twice the latency in the network plus a processing delay at the destination. The other ...
Transmission delay is a function of the packet's length and has nothing to do with the distance between the two nodes. This delay is proportional to the packet's length in bits. It is given by the following formula: = / seconds. where: is the transmission delay in seconds;
The transaction contains 32 write transfers. The initial latency for the write transfer is 8ns and burst sequential latency is 0.5ns. Calculate the total latency for single mode (no-burst mode), 4-beat burst mode, 8-beat burst mode and 16-beat burst mode. Calculate the throughput factor increase for each burst mode. Sol:-
