The NorNet Core site at the Simula Research Laboratory has now been equipped with a fourth ISP connection. This new connection to PowerTech provides DSL connectivity, with IPv6 in addition to IPv4. In total, the Simula site is now reachable via 4 different IPv4 networks (UNINETT, Kvantel, Telenor, PowerTech) and 3 different IPv6 networks (UNINETT, Kvantel, PowerTech). This site upgrade particularly further improves the possibilities for advanced research experiments on Multi-Path TCP (MPTCP) and the Stream Control Transmission Protocol (SCTP).
