Mobility Multihoming Duality for the Internet Protocol

In the current Internet, mobile devices with multiple connectivity are becoming increasingly common; however, the Internet protocol itself has not evolved accordingly. Instead, add-on mechanisms have emerged, but they do not integrate well. Currently, the user suffers from disruption to communication on the end-host as the physical network connectivity changes. This is because the IP address changes when the point of attachment changes, breaking the transport layer end-to-end state. Furthermore, while a device can be connected to multiple networks simultaneously, the use of IP addresses prevents end-hosts from leveraging multiple network interfaces — a feature known as host multihoming, which can potentially improve the throughput or reliability. While solutions exist separately for mobility and multihoming, it is not possible to use them as a harmonised solution for the end-host.

This work extended ILNPv6, an engineering solution of Identifier Locator Network Protocol (ILNP) implemented as a superset of IPv6 on the Linux kernel. The existing implementation was extended to harmonise mobility and multihoming. First, the mobility implementation was en- hanced to support rapid and continuous mobility; a comparative analysis against MIPv6 showed superior performance during high rate of handoffs. Second, multihoming was implemented and integrated with mobility; the evaluation with a flexible multi-connectivity scenario with load-balancing showed negligible loss and consistent throughput. Finally, the impact of the combined mobility-multihoming mechanism was evaluated with a real-time video stream application showing continuous uninterrupted real-time video playback at 2160p (4k ultra high definition). Overall, this work has demonstrated that mobility-multihoming duality is possible for end-hosts over IPv6 for existing applications without changing the network infrastructure.

Supervised by Prof. Saleem Bhatti with Dr Tristan Henderson as second Supervisor.

Thank you to the external examiner Prof. Mahesh Marina from the University of Edinburgh and Internal examiner Prof. Simon Dobson.

The viva took place on Microsoft Teams on 7/03/2022.

Congratulations David Letham!

Congratulations to David Letham who has been invited to the Gives Back Awards 2022, on behalf of University of St Andrews Charities Campaign.

David is one of the first winners of the making a difference Award. This new Award comes from students and staff who would like to nominate members of staff who have gone the extra mile within St Andrew’s community and beyond. Whether that be stepping up to help others during exceptional times, showing initiative or making a positive impact on the individuals/communities they have worked with

Enjoy the Ceremony!

 

Only One day to go until SISCO!

SISCO Conference, 5 & 6 February

Ian Gent, Chris Jefferson and Simon Dobson are all presenting at the SISCO conference this weekend. There will be social and networking events which include free food in the medicine cafeteria. We think that these will be nice opportunities for all students, speakers and staff to get to know one other.

You are all invited to these events, both on Saturday and Sunday.

You can get your free tickets to attend and further information on their Facebook page

Congratulations to our Emeritus Professor Ian Sommerville

Very many congratulations to our Emeritus Professor Ian Sommerville who has recently been awarded the 2022 Nancy Mead award for excellence in software engineering education.

https://mycseet.wordpress.com/nancy-mead-award-terms-of-reference/

The award will be presented at the (virtual) Conference for Software Engineering and Training next month.

This Award goes to individuals who have demonstrated outstanding contributions to software engineering education and training, as well as to the related area of software engineering professionalism. Contributions may include, but are not limited to: service to the community, papers, reports, books, tools, techniques and media for software engineering education, and outstanding practice of teaching that has been witnessed by the community at large. Contributions should have had an influence over an extended period of time at the international level. Contributions to software engineering itself (peer-reviewed research or practice) should be mentioned in a separate section of any nomination, but having made such contributions is not necessary in order to receive this award.

Well Done Ian!

Welcoming Prof. Giovanna Di Marzo Serugendo for our DLS on Tuesday 9 November

As part of the schools Distinguished Lecture Series we look forward to welcoming Prof. Giovanna Di Marzo Serugendo on Tuesday 9 November.

Prof. Giovanna Di Marzo Serugendo  received her Ph.D. in Software Engineering from the Swiss Federal Institute of Technology in Lausanne (EPFL) in 1999. After spending two years at CERN (the European Center for Nuclear Research) and 5 years in the UK as Lecturer, she became full professor at the University of Geneva in 2010. Since 2016, she is the Director of the Computer Science Center of the University of Geneva, Switzerland. She has been nominated in 2018 among the 100 digital shapers in Switzerland. Her research interests relate to the engineering of decentralised software with self-organising and emergent behaviour. This involves studying natural systems, designing and developing artificial collective systems, and verifying reliability and trustworthiness of those systems. Giovanna co-founded the IEEE International Conference on Self-Adaptive and Self-Organising Systems (SASO) and the ACM Transactions on Autonomous Adaptive Systems (TAAS), for which she served as EiC from 2005 to 2011.

This event will be held on Teams with further details to follow.

$2.2 million funding for former CS students

Hassan Khajeh-Hosseini, along with former CS students Ali Khajeh-Hosseini and Alistair Scott saw an untapped market to help engineers lower their cloud computing costs, creating Infracost as a result. Infracost provides developers with cloud cost estimates based on changes they make to their code infrastructure.

Hassan, the CEO, who attended The Robert Gordon University and The University of Edinburgh, and is a serial entrepreneur, with two of his companies he cofounded with his brother Ali (ShopForCloud and AbarCloud) being acquired. Ali, also attended The Robert Gordon University and The University of Edinburgh like his brother, and went on to obtain his Ph.D. from the University of St. Andrews, with his doctoral thesis focusing on cloud computing (Thesis: Supporting System Deployment Decisions in Public Clouds). His decade of expertise in the field played a critical role in the success and acquisitions of ShopForCloud and AbarCloud. Rounding out the team is Alistair, who attended the University of St. Andrews for his computer science degree. He was also a cofounder at AbarCloud and a senior software engineer at RightScale. These three together have impressive domain expertise and a successful entrepreneurial track record in cloud computing makes it likely that will make a massive impact with Infracost in the tech industry at-large.

SACHI research group in Canada for the annual CHI conference

  

This week members of the SACHI research group are in Canada for the annual CHI conference where they are presenting 8 papers and other research work.

Their research papers have been attracting media interest this week. The Times has covered their paper on Change blindness in proximity-aware mobile interfaces quoting Professor Quigley. 

         

 

App developers urged to cure phone ‘blindness’

While the verge and Engadget has covered the best paper Project Zanzibar: A Portable and Flexible Tangible Interaction Platform.

Hui-Shyong Yeo contributed to this research while he was a research intern at Microsoft Research last summer in Cambridge.

 

The research group has put together a page which describes all the efforts at CHI 2018 here

Next year CHI 2019 will be in Scotland while CHI 2020 will be in Hawaii on its way to Asia in 2021.

Members of SACHI are already involved in the planning for 2019 as associate chairs for the program and are looking forward to CHI here in Scotland next year
