An almost inexhaustible supply of bandwidth
The DWDM systems currently deployed in X-WiN offer the possibility to establish a great number of simultaneous connections (wavelengths) between the core-network sites. Thus, DFN-Verein is able to exploit an almost inexhaustible supply of bandwidth. These connections make up the optical platform of X-WiN, that is used for the interconnection of routers to an IP platform as well as for the establishment of Virtual Private Networks, called layer-2-VPNs. The layer-2-VPNs are built for closed user groups, particularly users with exceedingly high demands for bandwidth.
Each connection on the optical platform can be configured with a stand-by connection on a redundant route. This technique is called automatic protection switching and aims to meet highest demands with respect to availability.
The optical platform is connected to the GÈANT network and also to the national research and education networks of several neighbouring countries. This approach ensures the seamless integration of the users of X-WiN with the special networks of the international scientific communities like high-energy physics or resource providers like high- performance computing centers.
DFN-Verein continuously extends the optical platform according to its users' demands.
