S17. Describe the principle behind store-and-forward. What is the optimal packet size? Flashcards
What is the princple behind store-and-forward?
The principle behind store-and-forward is that a device receives a packet in its entirety before forwarding it to the next destination.
How does store-and-forward work?
When a device receives a packet, it stores the whole packet in its memory or buffer, checks it for errors, and then forwards it to the next hop in the network.
What is the purpose of store-and-forward?
The store-and-forward process ensures that the entire packet is received correctly before it’s transmitted further, minimizing the risk of data loss or corruption.
What is one of the key advantages of store-and-forward?
One of the key advantages of store-and-forward is its ability to handle packets of varying sizes and types. Since the device stores the entire packet before forwarding it, it can accommodate packets of different lengths and formats, including variable-length packets commonly used in Ethernet networks.
What is the optimal packet size?
The optimal packet size depends on various factors, such as network topology, traffic patterns, and hardware capabilities.
When are smaller packet sizes preferrable?
In many cases, smaller packet sizes are preferred for real-time communication applications or networks with high levels of congestion. Smaller packets can reduce latency and improve overall network efficiency by allowing more packets to be transmitted in a given time frame.
When are larger packet sizes preferrable?
Larger packet sizes may be more efficient for networks with high bandwidth and low levels of congestion. Larger packets can reduce overhead and increase throughput by minimizing the number of headers and trailers required for each packet.
What factors determine optimal packet size?
The optimal packet size is a balance between factors such as latency, throughput, and network efficiency, and it may vary depending on the specific requirements and constraints of the network environment.
