OpenDaylight – RESTCONF/YANG • OpenDaylight Controller contains Model-‐Driven
Service AbstracVon Layer (MD-‐SAL)
• MD-‐SAL autogenerates RESTCONF APIs for the objects in the models it learns about
• YANG data models can be on a device or present in a southbound plug-‐in
• New plug-‐in or device model added? Or updated? RESTCONF APIs are ready!!
• h[ps://wiki.opendaylight.org/view/OpenDaylight_Controller:MD-‐SAL:Model_Reference
• Plaborm with RESTCONF and MD-‐SAL plus YANG data models for network configuraVon, stats collecVon and service orchestraVon will be useful component of an SDN WAN OrchestraVon soluVon

PCE (Path Computation Element) – RFC4655
! Stateful PCE = Cisco inovace, rozšíření PCE architektury pro SDN
! Programovatelnost MPLS – delegace řízení LSP, stavová synchronizace
BGP-LS (Link State) – draft-ietf-idr-ls-distribution
! Redistribuce OSPF/ISIS topologie do BGP (nová AF a capability)
! SDN Controller má přesné informace o topologii; bezpečnost, škálovatelnost
RESTCONF a YANG – RFC6020, draft-bierman-netconf-restconf
! HTTP API pro komunikaci s SDN Controllerem (GET, POST,…)
! Data ve formátu XML, struktura definovaná v jazyce YANG
Na čem to běží: • Mac Air – 8GB DRAM, i5 1.3GHz 2c CPU, OS X Mavericks • IOS XR 5.1.1 (XRv v Cisco Modeling Labs) • OpenDaylight SNAPSHOT-0.1.2 SP Edition
Nejkratší cesta (SPF) mi nevyhovuje!
