| Summary: | Based on the analysis of the network infrastructure of the NSC KIPT specialized computer complex for processing of data obtained in the CMS experiment at the Large Hadron Collider, the internal communication channels
of the complex were modernized using the link aggregation technology. The upgrade has provided a significant increase of the information transfer rate for the most loaded links. Extension of the external communication channel
bandwidth to 2 Gbps and optimization of the routing for the transferred information using the GEANT and
LHCONE network infrastructures has led to an improvement in the quality of data transfers by the PhEDEx and
XrootD services. The optimal load distribution between the separate external channels and the Internet channel
bandwidth subdivision between the PhEDEx and XrootD services have been provided. A set of services have been
configured to monitor various parameters of the network. |
