Cache-Aware Compositional Analysis Of Real-Time Multicore Virtualization Platforms, Meng Xu, Linh T.X. Phan, Oleg Sokolsky, Sisu Xi, Chenyang Lu, Christopher Gill, Insup Lee

Departmental Papers (CIS)

Multicore processors are becoming ubiquitous, and it is becoming increasingly common to run multiple real-time systems on a shared multicore platform. While this trend helps to reduce cost and to increase performance, it also makes it more challenging to achieve timing guarantees and functional isolation. One approach to achieving functional isolation is to use virtualization. However, virtualization also introduces many challenges to the multicore timing analysis; for instance, the overhead due to cache misses becomes harder to predict, since it depends not only on the direct interference between tasks but also on the indirect interference between virtual processors and the ...


Migrating The Internet To Ipv6: An Exploration Of The When And Why, Mehdi Nikkhah, Roch Guerin Feb 2015

Migrating The Internet To Ipv6: An Exploration Of The When And Why, Mehdi Nikkhah, Roch Guerin

Departmental Papers (ESE)

The paper documents and to some extent elucidates the progress of IPv6 across major Internet stakeholders since its introduction in the mid 90’s. IPv6 offered an early solution to a well-understood and well-documented problem IPv4 was expected to encounter. In spite of early standardization and awareness of the issue, the Internet’s march to IPv6 has been anything but smooth, even if recent data point to an improvement. The paper documents this progression for several key Internet stakeholders using available measurement data, and identifies changes in the IPv6 ecosystem that may be in part responsible for how it has ...
