The Internet in its current form crucially relies on various communication protocols, which are distributed procedures and algorithms governing how different computers in the Internet can reach each other and exchange messages and data reliably. Two core classes of protocols are routing protocols, which help to find paths between arbitrary computers, and transport protocols, which achieve reliable data transfer over an inherently unreliable network. In this course we develop an advanced understanding of the operation, performance and scalability of selected protocols in these two classes (for example the OSPF routing protocol, and the TCP and other transport protocols). Students will implement and simulate selected aspects of such protocols and evaluate their performance.
The Internet became a very important part of our daily lives. It is constantly evolving to accommodate new online services or to support existing services with better quality. At the core of the Internet are so-called routers and switches, their main function being to identify efficient routes for data packets and to actually forward packets in large volumes along these routes. In this course we will study Internet routing and Internet routers / switches in some detail, including the recent developments around “Software-Defined Networking” (SDN). Besides looking at technological and protocol aspects, we will also study IP traffic engineering, where techniques from mathematical optimization / mathematical programming are used to allow network operators to optimize network traffic flow to meet customer and provider objectives.
1. Critique the Internet routing architecture and the OSPF routing protocol including how both have been influenced by scalability considerations [WA1, WA10]2. Implement and test relevant parts of a given specification of a routing protocol [WA1, WA2, WA3, WA5, WA9, WA10]3. Analyse and configure OSPF routinga for a given network topology [WA1, WA5, WA10]4. Apply the fundamentals of linear optimization and of a solution algorithm for linear optimization problems [WA1, WA10]5. Formulate and numerically solve network traffic engineering problems as optimization problems and present the results [WA1, WA2, WA3, WA5, WA10]

For precise assessment due dates, please refer to the AKO | Learn page.
Students will be provided with two booklets for the main part of the course.
The Computer Science department's grading policy states that in order to pass a course you must meet two requirements:1. You must achieve an average grade of at least 50% over all assessment items.2. You must achieve an average mark of at least 45% on invigilated assessment items.If you satisfy both these criteria, your grade will be determined by the following University-wide scale for converting marks to grades: an average mark of 50% is sufficient for a C- grade, an average mark of 55% earns a C grade, 60% earns a C+ grade and so forth. However if you do not satisfy both the passing criteria you will be given either a D or E grade depending on marks. Marks are sometimes scaled to achieve consistency between courses from year to year.Students may apply for special consideration if their performance in an assessment is affected by extenuating circumstances beyond their control.Applications for special consideration should be submitted via the Special Considerations website within five days of the assessment.Where an extension may be granted for an assessment, this will be decided by direct application to the Department and an application to the Examinations Office may not be required. Special consideration is not available for items worth less than 10% of the course.Students prevented by extenuating circumstances from completing the course after the final date for withdrawing, may apply for special consideration for late discontinuation of the course. Applications must be submitted to the Examinations Office within five days of the end of the main examination period for the semester.
