Rate based call gapping with priorities and fairness between traffic classes

TL;DR

This paper introduces a novel rate-based call gapping method that combines the advantages of Token Bucket and Weighted Fair Queuing to achieve maximum throughput, priority handling, and fairness across traffic classes without queues.

Contribution

It proposes a new hybrid call gapping approach that integrates Token Bucket and fair queuing, supported by a mathematical model and extensive simulations.

Findings

The new method achieves higher throughput than traditional Token Bucket.

It ensures fairness and priority handling across traffic classes.

Mathematical proofs validate the effectiveness of the proposed approach.

Abstract

This paper presents a new rate based call gapping method. The main advantage is that it provides maximal throughput, priority handling and fairness for traffic classes without queues, unlike Token Bucket which provides only the first two or Weighted Fair Queuing that uses queues. The Token Bucket is used for call gapping because it has good throughput characteristics. For this reason we present a mixture of the two methods keeping the good properties of both. A mathematical model has been developed to support our proposal. It defines the three requirements and proves theorems about if they are satisfied with the different call gapping mechanisms. Simulation, numerical results and statistical discussion are also presented to underpin the findings.
