    1. Switch 7050 is expected to arrive some time around October; we have already transceivers, short cables and patch panel to connect up to 32 VTPs to it using two 10GBit links per VTP
    2. Fiber installation between hallb forward carriage and hallb counting room should be done this summer, will be enough for 24 VTPs using two 10GBit links per VTP
    3. We have only one fiber between hallb counting room and counting house second floor available right now, will order more fibers installation, may take several months
    4. There are several available fibers between counting house second floor and computer center (like 6), we can use a couple of them for our test
    5. Summary: sometime in October, we should have 48 10GBit links from 24 VTPs connected to the switch in hallb counting room, with that switch connected to computer center by 2x100GBit links
