  1. In this section, we propose a distinction between different types of traffic by source or destination. Please take a look at the figure below, which attempts to illustrate the distinctions in terminology. Traffic figure

    T1 - all traffic from customer sites
    T2 - all traffic to customer sites

    T3 - all traffic to external networks
    T4 - all traffic to the NREN backbone

    External traffic = all traffic to and from GÉANT, the Commercial Internet, Internet exchanges, etc. (made up of T3 and T4 above)

  2. Flow Total IP traffic during 2008 Volume of IPv6 traffic if known during 2008 Percentage of total IP traffic to/from commercial internet Percentage of your commercial internet traffic that is exchanged freely through peering agreements
    T1 3025.0      
    T2 2943.0      
    T3 2618.0   89.0 10.0
    T4 2536.0   85.0 7.0
  3. Flow Total IP traffic during January 2009 Volume of IPv6 traffic if known during January 2009 Percentage of total IP traffic to/from commercial internet Percentage of your commercial internet traffic that is exchanged freely through peering agreements
    T1 358.0      
    T2 265.0      
    T3 300.0   94.0 8.0
    T4 207.0   87.0 7.0
  4.   Campus LAN Access Network NREN backbone Metro/Regional Networks External Links
    % of institutions experiencing no or very little congestion happy 80.0 100.0 95.0 100.0 100.0
    % of institutions experiencing some or moderate congestion plain 20.0 0.0 5.0 0.0 0.0
    % of institutions experiencing serious congestion angry 0.0 0.0 0.0 0.0 0.0

  12. Traffic Type   Do you measure the level of utilization, if so, how?
    IP Traffic ( )Yes (x)No We do not use IPoDWDM
    SDH ( )Yes (x)No We do not use SDH
    VLAN (x)Yes ( )No Yes using Cricket
    Ethernet (x)Yes ( )No Yes using Cricket
    Others (known) ( )Yes ( )No  
    Unknown ( )Yes ( )No  
  13. C2. T4 - the following note goes along with the 7% entry -

    These values changed significantly in the following month, when peering with Google began. The February 2009 figures respectively 19% and 10%.

    C3. The total of each column does add up to 100% but for some reason it is not coming out as that.

    C.11 - This question is a little too vague. HEAnet has a DWDM optical network that transports 10GE encapsulated in OTN frames. We also have CWDM which uses GE framing directly on the fiber.
