Introduction to OpenDaylight and its Helium release Srini Seetharaman srini.seetharaman@gmail.com Oct 2014
Problem in Todays Ossified Network Routing, management, mobility management, access control, VPNs, Feature Feature Million of lines of source code 6000+ RFCs Barrier to entry Operating System Billions of gates Bloated Power Hungry Specialized Packet Forwarding Hardware Many complex functions baked into the infrastructure OSPF, BGP, multicast, differentiated services, Traffic Engineering, NAT, firewalls, MPLS, redundant layers, 2
Solution: Software-defined Network Unchanged mgmt API North-bound interface API IP routing service LB FW Legacy Router service service Network Operating System OpenFlow or other API Simple Packet Forwarding Hardware Simple Packet Forwarding Hardware Simple Packet Forwarding Hardware Simple Packet Forwarding Hardware This is the purist view with clear separation of data and control Simple Packet Forwarding Hardware 3
Expanded View of SDN in OpenDaylight Hybrid approaches supported Mgmt plane Orchestration FIB programmable through OpenFlow, irrespective of whether there is an onboard control plane 1. Extnl. Control plane Intl. Control plane Data plane Programmable exclusively through embedded control plane: e.g., Yang modeled NetConf, OpFlex 2. Hybrid control plane where the hardware contains a more open platform for adding logic Programming both embedded control plane and FIB: e.g., Open vSwitch 3.
SDN Killer App #1: Network Virtualization SDN-based Virtualized Network Platform Computing Infrastructure Dynamic, Programmable, Automated 5
SDN Killer App #2: Service Function Chaining Internet Internet NFV 6
Business Potential of SDN Business potential How? Reduced time to revenue Speed up of service provisioning New revenue Through new business models centered around on-demand usage Improved policy compliance Ensure that cloud workload is compliant with enterprise policies (e.g., access control) OpEx saving Automated operations and easier management of resources Reduced OpEx during upgrades Introduce new functions and service by replacing just software stack 7
OpenDaylight Consortium Heavy industry involvement and backing Focused on having an open framework for building upon SDN/NFV innovations Not limited to OpenFlow innovations, but in fact decoupled from it allowing the two to evolve independently 9
