  1. ONF Configuration and Management WG Jürgen Quittek quittek@neclab.eu

  2. ONF Overview • Open Networking Foundation • Standardizing OpenFlow-based SDN • http://opennetworkingfoundation.org • Working groups • Extensibility OpenFlow: wire protocol, extensibility, features ,… (OF 1.x) • Config-mgmt Protocol & schema for configuration of a switch (OF-Config 1.x) • Testing-interop Interoperability tests, plug-fests; performance benchmarking • Hybrid OpenFlow in legacy networks; hybrid switches, hybrid networks • Architecture SDN architecture based on OpenFlow • Forwarding Abstractions Table Typing, Forwarding plane models

  3. Config & Mgmt. WG:Problem statement • Bootstrap OpenFlow network • Switch connects to controller • Controller(s) to connect to must be configured at switches • Allocate resources within switches • Ports • Queues • . . . switch switch switch switch controller controller

  4. Reference Model • Configuration Point • Source of switch configuration • OpenFlow Capable Switch • Hosts one or more logical switches • OpenFlow Controller • OpenFlow Logical Switch • instance of an OpenFlow Switch Configuration Point Configuration Point Configuration Point Configuration Point OpenFlow Controller OpenFlow Controller using IETF Netconf & XML data models OF-CONFIG OpenFlow OpenFlow OpenFlow Capable Switch resources (ports, queues) OF Logical Switch OF Logical Switch

  5. OF-CONFIG scope and releases WG established in Sep 2011 • OF-CONFIG 1.0 (Jan 2012) based on OpenFlow 1.2 • assigning controllers to logical switches • retrieving assignment of resources to logical switches • configuring some properties of ports and queues • OF-CONFIG 1.1 (Apr 2012) based on OpenFlow 1.3 • added controller certificates and resource type "table" • retrieving logical switch capabilities signaled to controller • configuring of tunnel endpoints • OF-CONFIG 1.1.1 (Aug 2012) based on OpenFlow 1.3.1 • consolidation of version 1.1, fixing small inconsistencies • OF-CONFIG 1.2 (early 2013) based on OpenFlow 1.3.1 • features still under discussion, candidates include • retrieving capable switch capabilities, configuring logical switch capab. • assigning resources to logical switches • simple topology detection • event notification

  6. Use of Netconf and Yang • Netconf was chosen as management protocol • not necessarily accepted as ideal solution • still discussing alternatives • XML schema was chosen as modeling language • Yang is also used, but XML is normative • normative XML schema generated from Yang code • So far, the focus has been on configuration • bootstrap of an OpenFlow network is the obvious first thing to do • New work items will be more on OAM • incl. event notifications

  7. Call home issue • In the OF-CONFIG spec the primary scenario is using Netconf with connections initiated by the configuration point • However, several members asked for also supporting call home sceanrios with switch initiating Netconf connections • switch configured with DHCP • receives own address and configuration point's address • no need to manually add switch to configuration point's DB • OF-CONFIG document states: use BEEP if you need switch-initiated connections • now, BEEP is getting "historic" • Options: • drop call home scenario • ask ITEF to further support call home
