Phase V Routing
The CERN Routing transition was made in steps, in order to minimise any impact. At the end of October, the HEPnet International DECnet Circuits between CERN, Italy, UK, DESY, and PSI/CH were changed to use Phase V protocols. At the end of November, the CERN site Area (Level 2) routers were also changed to use Phase V protocols. The CERN routing transition will be completed next year when the remaining area 22 Level 1 routers will also run Phase V.
