  1. GN3plusWhat the network should do for clouds? Christos Argyropoulos National Technical University of Athens (NTUA)Institute of Communications & Computer SystemsNetwork Management & Optimal Design Lab(NETMODE)(GN3plus - GRNET 3rd Party) GN3plus Symposium, October, 2013, Vienna

  2. Someone asked for.. • Dynamic provisioningNo-human interaction, fast provisioning/deployment • Elasticity • Resource upscaling/downscaling on demand • Mobility/Migration • Rearrangement of resources • Isolation • Sharing of resources in a multi-tenant environment among users (tenants) that are unaware of each other profiles(the ultimate: independence without interference)

  3. Clouds started to deliver..What about networks ? • Need for.. Enhancements.. • Intra – DC (Data Center) networking • Higher Port density • Lower latencies on switchingProgrammable Fabric/Flow forwarding • Software switching inside hypervisors • Inter – DC networking Layer 2 connectivity Multi-tenancy Resource/Service Mobility Use-cases: load-balancing, disaster recovery

  4. Intra – DCCloud Requirements Clouds generate Requests

  5. Intra – DCNetwork Design Challenges Requests raise Challenges Port density Low latency switching High availability etc.

  6. Intra – DCNetwork Design Innovation Challenges trigger Innovation

  7. Intra – DCNetwork Design Solutions SDN Innovation generates Solutions

  8. Inter – DCCloud Requirements Clouds generate Requests

  9. Inter – DC Network Design Challenges Requests raise Challenges

  10. Inter – DC Network Design Innovation Requests trigger Innovation

  11. Inter – DC Network Design Innovation OpenDaylight Open vSwitch … SDN Innovation generates Solutions
