ONRC Update - Open Networking Research Center
ONRC Update ONRC Spring Day May 12, 2015 Open Networking Research Center (ONRC) Berkeley Stanford Open Network Lab Scott Shenker Nick McKeown Sylvia Ratnasamy Guru Parulkar Sachin Katti Phil Levis Exec Director: Guru Parulkar VP Eng: Bill Snow Chief Architect: Larry Peterson PhD/Postdocs Research 25 Engineers/Tech Leads (includes PlanetLab team) Open Source Platforms ONRC MeeAngs • Fall: host a joint meeAng of UC Berkeley, Stanford, and ON.Lab – Expect a joint meeAng in September/October 2015 • Spring: provide more flexibility – Allow each organizaAon to organize its own meeAng with sponsors – ONRC Stanford and ON.Lab decided to do it together Stanford: Major Themes • Programmable Networks • SDN for Dense WiFi • Personal WiFi Networks • SDN for Cellular Wireless Networks Programmable Networks • SDN clarified the roles of the control plane and the forwarding plane. • To really program the network we must oXen dictate what happens in the forwarding plane. • We are very interested in: – How to program all forwarding planes (hardware and soXware) – What new things we can do. • We would like to help build a community for those interested 1 - Created P4 language - Building community (h^p://p4.org) P4 code 2 - Compiler techniques Compiler 3 - New primiAves - New possibiliAes AcAon acro Fixed AMcAon Compiler Target 4 Match Table ACL Table AcAon acro Fixed AMcAon IPv6 TTable Match able AcAon acro Fixed AMcAon IPv4 TTable Match able Fixed AM cAon AcAon acro L2 Table Match Table Parser Programmable Networks Queues 6 SoXRAN ¡ How do we bring SDN & NFV to the radio access networks at the mobile edge? ¡ The RAN is unique ¡ Most expensive part of the network ¡ Requires Aght coordinated control to improve wireless capacity ¡ Historically, has been very hard to add new services ¡ SoXRAN: Pladorm to enable RAN network services to be specified as modular data & control planes and flexibly realized on commodity HW spanning the central office and cell sites ¡ Low latency (< 1ms) scalable control planes for radio control ¡ Programmable L1-‐L7 packet pipelines for LTE/5G that are automaAcally split across the CO & cell sites to accommodate service provider transport constraints SoXRAN Architecture SoXRAN: AbstracAons & System Abstrac(ons: Flowgraphs for data plane packet processing pipelines, and control graphs for controller applicaAons So.RAN OS: Pladorm to execute any combinaAon of flow and control graphs expressed in high level programs on COTS distributed hardware while meeAng latency & throughput requirements ON.Lab: Open Source Pladorms and Infrastructure Open Source ONOS Ecosystem ON.LAB SERVICE PROVIDER PARTNERS China Unicom to join soon!
