Kapitel 7.2 - Stocker State of Internet

• Large cloud and content providers have built their own high capacity networks to connect strategically important locations like datacenters or interconnection points

  • Reduction of reliance on the public best-effort internet

  • Results in more fuctionality, better performance & improved customer experience and better evolvability

• The public internet lacks of such dynamism -> functional and innovational disparities rise

• Topological innovations like IXPs or CDNs and the localization of network traffic and ressources

  • Moving servers thus content closer to end-users and devices

• Large cloud and content providers have built private backbone networks to connect strategically important locations

• Next-generation mobile access technology (5G and 6G)

Desirable because of

• a better performance and reliability -> improved customer experience

• reduced latencies of signal transmission or protocoll inefficiencies

• Describes the number of networks borders (hops) a datapacket needs to traverse between two communication endpoints

• “Cut out the middlemen”, shortened delivery chain to strategically reduce or avoid coordination problems and congested interconnections

Remote peering (RP): When a network peers at an IXP without having physical presence in the IXP’s infrastructure and/or through a reseller.
