Congestion Control Design

Congestion Control

This article describes congestion and overload control techniques used in Realtime Systems.

Congestion Control Algorithm

A typical congestion control algorithm is covered here. Concepts like congestion levels and hysteresis are introduced.

Network-wide Overload Control

Techniques adopted to avoid network-wide overload are discussed here. The focus is on reducing the network load rather than just the load on one exchange.

Congestion Control Triggers

Congestion Control and Overload Triggers and mechanism for generating them are covered in this article. 

Queueing Theory

Queueing Theory Basics

Understanding queueing theory is important for developing congestion congestion control algorithms. This article covers the basics.

M/M/1 Queueing System

Here we describe M/M/1 queueing and its applicability. Equations describing the M/M/1 queueing are also covered.

Resource Dimensioning Using Erlang-B and C

Erlang-B and Erlang-C can be used to determine the total number of resources needed in the system.
