1. Internet Traffic Management System Broadhop – case study The following case study and comments are for the QUESTnet & AARNet Workshop only, the views and opinions expressed do not necessarily represent the views and opinions of UQ.

2. In 2008 a project was started to address the issues UQ began to face as the internet use at UQ spiralled out of control for the existing systems. Overview -Replace legacy Internet management system known as Quotient written by UQ developers & deployed 2004/5. This system for its time functioned very well but as the Universities internet use and dependencies on accessing the Internet grow the system began to fail. Major system limitations, UQ had a 1Gbps Internet link but Quotient could only handly1/3 of this capacity. System had limited redundant and after system failure it could take up to 3hrs for all users to regain Internet access, system could not distinguish between the different traffic types i.e. research vs internet Facts -UQ Internet traffic was almost doubling year on year. -Over 60% of the general network use is for accessing content and services online. -There is a quickly growing move towards cloud based Internet services such as Live@Edu for student email, RightNow CRM, iTunesU, and PageUp People HR. -Wireless coverage soon to be amongst the largest in the world allowing Staff and Students to be connected at any UQ campus, many hospitals, and even the CityCats. -Faculties increasing internet content/tools into learning material, Journalism –Youtube & Facebook, Business – Linkedin. -On average over 180,000 people are using our Internet services everyday. Solution -Implementation of Broadhop which is a world leading appliance for policy enforcement and subscriber management, the new system gives UQ the ability to manage internet use at new levels. The system has the ability to handle 10Gbps of capacity and up to 1 million active subscribers, it is fully redundant with duplicate infrastructure across 2 data centres at St Lucia and if there is ever an event of system failure all users can be back online in less than 2minutes. Broadhop distinguishes the different traffic types giving staff and students access to 50% more quota free content than previously available. Overview
