Low TCO and high-speed network infrastructure with virtual technology
Hideo Masuda, Kazuyoshi Murata, Yu Shibuya · 2009
In our university, we have updated our network infrastructure from ATM (Asynchronous Transfer Mode) network system to 10-Giga Ethernet system in March, 2009. The new system has 2 major features. One is ring topology with 10GBASE-X Ethernet. This feature enables lower initial cost than star topology because an ordinary star topology requires very expensive core switch system which can contain many 10GBASE-X GBICs (this device is also very expensive). The second is Virtual Chassis technology of Juniper Networks. This feature allows up to 10 switches to be interconnected and managed as a single, logical device. Thus it enables lower management cost than a system with many individual switches. In this paper, we show merits and demerits of our system against ordinary star topology.
