  • 1. Cloud Networking: Network aspects of the cloud Thomas Edwall, SAIL Project Manager Ericsson AB FIA, session 2.3: Aalborg, Denmark, May 11th, 2012Fifth Future Internet Cluster12-05-16 1 SCALABLE & ADAPTIVE INTERNET SOLUTIONS SAIL Public
  • 2. Towards a Carrier Cloud Flexible networking & distributed virtual infrastructure Legacy appsApplication evolution in cloud (IaaS) Legacy apps on Drivers: IaaS including networking dedicated servers DC based clouds in one package, Tailored multisite connectivity Drivers: Server consolidation economies of scale, pay-per- use / scale-with-demand Apache SCALABLE & ADAPTIVE INTERNET SOLUTIONS Mid ’90’s Mid ‘00’s Public SAIL Mid ’10’s
  • 3. Current cloud context Compute• Main focus is about Connectivity Storage computing and storage resources in a ”one-to-one” fashion Enterprise Wide Area Network Public• Connectivity between (Private Cloud DC) Cloud DC those components always forgotten Unpredictable Security issues response times with business critical data SCALABLE & ADAPTIVE INTERNET SOLUTIONS SAIL Public
  • 4. Add the network aspect to the equation!• Satisfying application requirements for latency and bandwidth is key.• Network constraints need to be by added into the Approach #1: Distribute cloud resources in the network cloud optimisation equation 6 SCALABLE & ADAPTIVE INTERNET SOLUTIONS SAIL Public
  • 5. Boundaries between domains Intra-domain interface Inter-domain interface SCALABLE & ADAPTIVE INTERNET SOLUTIONS SAIL Public
  • 6. Taking interoperability into account Adding network aspects Approach #2: Assess which network domain or Data Center • Assure interoperability, both to put your cloud resources in. intra- and inter-domain Intra-domainInteroperability will be needed in bothcases. There will always be boundaries Inter-domain 6 and domains… 6 SCALABLE & ADAPTIVE INTERNET SOLUTIONS 6 SAIL Public
  • 7. Interoperability between clouds requirecontrol of:• How to request resources • How to realise/implement the requested connectivity Distributed Infrastructure Services Link negotiation, protocol Infrastructure: VMs, Storage & agreement and setup Virtual Network SCALABLE & ADAPTIVE INTERNET SOLUTIONS SAIL Public
  • 8. OCNI and DCP• OCNI: • DCP: – SAIL proposed extension to – SAIL proposed protocol for the OCCI interface/API from negotiating connectivity OGF parameters on domain – Extends the API to not only boundaries manage ‘compute’ and – Typically such parameters are ‘storage’, but also dependent on domain specific ‘networking’, in a cloud technologies and environment. management policies not – Service control model for disclosed by the domain. presenting high level resource Hence cannot normally be set requirements and delegate by the requester. them across infrastructure (IaaS) services.

  • 10. Final words• SAIL is about networking• SAIL also caters for interoperability aspects of the services and APIs developed• SAIL will be demonstrating Cloud Networking at FuNeMS in Berlin in July! SCALABLE & ADAPTIVE INTERNET SOLUTIONS SAIL Public
