Queueing Properties

In a queue, we can model an arrival process with a deterministic process. However, when aggregated, arrival processes are random events. So we model them with a random process. The study of random arrival processes is part of a discipline ... Read More »

Circuit Switching Concepts

Circuit switching technology appeared long before packet switching. It appeared to support Telephone calls first, then was used for computer communication. In the past, a dedicated physical circuit was formed by Switchboard Operators each time a phone A wants to ... Read More »

Switching And Forwarding

Backplane: a shared bus over which all packets pass through On a packet switch, each egress interface has a queue (the output queue) Recall from the “Principle of Packet Switching” article that: On an egress link, only one packet is ... Read More »

A Simple Deterministic Queueing Model

Queues can be studied with a simple deterministic model. A Deterministic queueing model helps to learn about the dynamics of a packet in a network. This model defines these functions: – A(t):  the cumulative number of bits (or bytes) that ... Read More »
