TERENA Compendium of National Research and Education Networks In Europe /Network3A.2 Numbers of PoPs, Managed Links andManaged Sites on the NetworkThe number of Points of Presence (PoPs) on the network and the numbers ofmanaged links and managed sites are indicators of the amount of resourcesneeded for the NREN to maintain the network. A PoP is defined as a point on theNREN backbone which can connect client networks or aggregations of clientnetworks, such as MANs or external networks. Note that this is different from, forexample, managing a router in a secondary school (something which is also doneby a number of NRENs).The number of managed links is the number of NREN-managed links that carryproduction traffic. The number of managed sites is the number of sites where theNREN manages routing or switching equipment.As can be seen from the table, NRENs vary considerably in this respect. Thus,ARNES of Slovenia manages the equipment at many secondary and primaryschools and thus has 1198 managed links. In many other countries, the links froma PoP on the backbone or from a MAN to the end user are managed by otherbodies.The information about the number of optical PoPs on the network, together withother information e.g., about dark fibre on the network, gives an indication ofthe spread of optical networking in the NREN. For ease of comparison, we haveshown the numbers of managed links and managed sites in 2007 as well. Thedarker colour indicates a significant change in those numbers.Table 3A.2.1 Numbers of PoPs and of Managed Links and Managed Sites on the NetworkCountry NREN # ofPoPs# ofOpticalPoPs# ofManagedLinks2007# ofManagedLinks2008# ofManagedSites2007# ofManagedSites2008EU/EFTA CountriesAustria ACOnet 17 8 22 24 15 15Belgium BELNET 21 21 29 63 16 21Bulgaria BREN 10 0 30 30 10 10Cyprus CYNET 3 0 15 23 3 3CzechCESNET 39 14 45 51 29 39RepublicDenmark UNI-C 7 5 0 23 20 20Estonia EENet 16 4 20 20 16 16Finland Funet 18 6 100 100 16 18France RENATER 40 50 50Germany DFN 54 54 76 96 49 54Greece GRNET S.A. 38 22 62 78 63 79Hungary NIIF/42 42 45 47 40 42HUNGARNETIceland RHnet 13 13 15 13 14 14Ireland HEAnet 8 0 90 100 10 12Italy GARR 42 8 53 52 38 42Latvia SigmaNet 1 0 79 40 1590 10Lithuania LITNET 31 6 200 200 200 200Luxembourg RESTENA 12 0 59 59 57 57MaltaUoM, IT2 0 17 1 2ServicesNetherlands SURFnet 256 256 336 336 262 256Norway UNINETT 40 4 240 240 385 385Poland PIONIER 35 71 28 31 23 25Portugal FCCN 9 5 11 11 9 932
