The technical intervention on the ReCaS-Bari data center border router, scheduled for September 12,  2017, carried out in collaboration with the GARR, the research network provider, was completed successfully.
During the intervention  the Border Gateway Protocol (BGP), a modern routing protocol that connects multiple routers belonging to several autonomous systems, was enabled.
By adopting BGP, ReCaS-Bari can implement dynamic routing autonomously, without relying entirely on the GARR,  choosing the routing on the base of the "use case": it will be possible to separate data transfers that relate to CERN experiments by other types of transfers, with a net gain in flexibility and elasticity of the system.
At the same time, the speed of the connection to the GARR network was doubled, with data now traveling at 20 Gbit / s.
The intervention was completely transparent to users, who did not notice any effect on their resources.
It is however recommended to monitor your data transfers in the coming days and report any suspicion of malfunctioning.
The band's doubling during the last September 12  intervention, represents the first step towards a 100 Gbit / s ReCaS-Bari connection bandwidth.
