Typically, the arrival of packets at a queue is periodic evenly spaced random a and b none of the above must say why to get best answer

Solution

Queuing allocates both bandwidth and buffer space
• Bandwidth: which packet to serve (transmit) next
• Buffer space: which packet to drop next (when required)
• Queuing also affects latency.

In the FIFO queuing discipline packets enter the queue at the tail and leave it from the head.

•RED is generalized by Active Queue Managment (AQM).

RED gateway has two separate algorithms.

The algorithm for computing the average queue size determines the degree of burstiness that will be allowed in the gateway queue.

The algorithm for calculating the packet-marking probability determines how frequently the gateway marks packets, given the current level of congestion.

The gateway to mark packets at fairly evenly-spaced intervals, in order to avoid biases and to avoid global synchronization, and to mark packets sufficiently frequently to control the average queue size.
