Computer Systems and Networks Group



The Computer Systems & Networks Research Group at UofT works on projects
that cover a diverse range of experimental and theoretical research,
including operating systems, network security, mobile code
architectures, high-performance computing and wireless networking.


The systems side works on a range of experimental projects on Internet
systems and services. Our interests span Web-based and peer-to-peer
systems design, network measurement and traffic analysis, fault-tolerant
Internet systems, wireless networking, and network security. Our mission
is to investigate high-impact research avenues that will shape the next
generation Internet systems and services.


The networks side engages in both theoretical and experimental research:
while we use modeling and analytical techniques to study fundamental
problems in computer networks, we also conduct experimental studies and
build real systems. Our research covers a broad range of topics

Internet Connection Alternatives for Home Networks

Most people, particularly in urban and suburban areas, enjoy several options for how to connect to the internet. The connection method you choose affects how a home network must be set up to support internet connection sharing.

Like DSL, a cable modem is a form of broadband internet connection. Cable internet uses neighborhood cable television conduits rather than telephone lines, but the same broadband routers that share DSL internet connections also work with cable.

Cable internet is perennially more popular than DSL in the United States, but in many other countries, the reverse is true.
