In a ring topology, each end host has a transceiver that breaks the circuit of the ring. Unlike a bus topology where each end host passively listens to the bus, each end host actively participates in the ring regardless of a frame’s destination. If an end host receives a frame with header addressed to itself, the end host will copy the frame from the ring; otherwise, the end host will forward the frame towards the next end host on the ring. In a ring topology, frames typically flow in a single predetermined direction.

Suppose s = 1:

For example, s = 1, t = 1:

Suppose s = 2:

For example, s = 2, t = 21:

As indicated by the examples, the interarrival times depend on s. Thus, the source is not memoryless.

Suppose s and t are >= 0:

For example, s = 1, t = 1:

For example, s = 2, t = 21:

As indicated by the examples, the interarrival times do not depend on s. Thus, the source is memoryless.
