  1. ViSION Status Update Dan Savu Stefan Stancu D. Savu - CERN openlab

  2. Overview • Introduction • Update on Software Defined Networking • ViSION Software Stack • HP SDN Controller • ViSION Core Framework • Load Balancer Module • The Health Monitor Module • The Regressive Testing Application D. Savu - CERN openlab

  3. The ViSION Project • CERN openlab - HP Networking collaboration • Traffic orchestration • Software Define Networking approach • Based on OpenFlow • Started in February 2012 • 2 engineers, 3 years CERN IT/CS recognized the need to scale CERN’s perimeter firewall capacity to cope with the increase of internet traffic. D. Savu - CERN openlab

  4. SDN: Centralized controller implementation App App App Network Operating System • Open interface to hardware (e.g. OpenFlow) • Anybody can innovate Simple Packet Forwarding Hardware Simple Packet Forwarding Hardware Simple Packet Forwarding Hardware Simple Packet Forwarding Hardware Simple Packet Forwarding Hardware D. Savu - CERN openlab

  5. OpenFlow/SDN update • Still a very dynamic area • ONF is active in refining existing versions and defining new ones: • Controllers: • Open source: Beacon, Floodlight, NOX & POX, Trema, Ryu, Open Daylight, Open Contrail • Commercial: Big Network Controller (Big Switch), Programmable Flow (NEC), Contrail • Cloud orchestration integration: Neutron/Quantum • Core part of the OpenStack platform, enabling network as a Service • Modular plugin design allows interfacing to SDN controller platforms D. Savu - CERN openlab

  6. OpenFlow – new controllers • POX • Python only version of NOX (initial OpenFlow controller) • Targeted largely at research and education. Suited for rapid prototyping • Open Daylight (04/2013) • Linux Foundation project – open source • Joint industry effort. Virtually all the big players are contributing members • Juniper launches SDN controller (09/2013) • Based on Contrail Systems acquisition from 12/2012 • Open source (OpenContrail) and commercial (Contrail code + service and support) • Virtualization controller (network overlays) • HP Virtual Application Network SDN Controller • October 21st product release (codename Flare) • OpenFlow 1.3 support • High Availability • Infrastructure controller (physical OF network fabric) D. Savu - CERN openlab

  7. Overview • Introduction • Update on Software Defined Networking • ViSION Software Stack • HP SDN Controller • ViSION Core Framework • Load Balancer Module • The Health Monitor Module • The Regressive Testing Application D. Savu - CERN openlab

  8. ViSION - HP SDN Framework D. Savu - CERN openlab

  9. ViSION Openflow Fabric External Net • OpenFlow fabrics desired functionality: • (1) Classification • (2) Load Balancing • (3) Mirroring • (4) Fault tolerance • Potential limitations (early days for OF) • No mirroring support in early OF versions • Classification based on port ranges scales poorly • Uniform load distribution not straight forward • Can’t hash on high entropy bits (e.g. lower IP bits) • Adaptive load distribution is complex • Requires API for synchronizing the FW’s state • Investigating migration to OF 1.3 with HP to address some of these limitations OpenFlow Fabric Stateful Firewalls Trusted Bypass OpenFlowFabric Internal Net D. Savu - CERN openlab

  11. HP SDN Controller Overview MS-Lync Federation Hadoop Partner 3rd party Apps Customer Applications Sentinel Base OpenFlow Controller Appliance • Virtual Appliance deployed as SW on an Industry standard x86 server • OpenFlow 1.3 Controller • Built-in Network Services • Appliance Administration A Distributed Platform for High-Availability & Scalability • Controller Clustering for Load-Balancing and Fail-Over • Control State Mirroring across cluster for transparent failure recovery Extensible Platform for SDN Application Developers • Embedded Java Application Deployment • REST APIs • GUI Cloud App Connectors . . . RESTful API ... App Mgr Clustering Security Backup/Restore Alerts ... Diagnostics Topology Device Mgmt Path Calculation Provisioning Openflow 1.3 Engine Standard interfaces and control protocols HP Network Infrastructure D. Savu - CERN openlab

  12. ViSION/ Core Framework • Traffic orchestration decomposition • Physical layer • Translation layer • Logical layer • Core module • Implements the first two layers • Provides support for redundancy by using multiple links/paths • Allows the higher logical layer to focus on traffic orchestration only • Integrated with latest HPN Controller • Status: • code development to end this sprint • final package to be delivered before our visit to HPN (mid October) Physical Translation Logical D. Savu - CERN openlab

  13. Balancer Int. Network User Interface • Allocates flows to resources based on • Resource capacity • Resource availability • Resource load • Higher level of abstraction • Deals with the available resources and consumers • The core implements its decision into the physical OF fabric • Flow allocation • Static  compromise for stateful firewalls • Dynamic • High availability • Relocate flows in case a resource becomes unavailable Balancer Balancer Ext. Network Health monitor & Traffic statistics D. Savu - CERN openlab

  15. ViSION/ Health Monitor Module • Real-time resource status information • Flexible module system • Multi-module data aggregation per agent • Custom agent configuration • Current modules: • SNMP • Ping • HTTP Web Request • LinkProbe via OF packet injection • Status • finalized, ready for hp code review • summer student involvement REST API Hmon App Agents Data Collection Module(s) Active Probe(s) Resource(s) D.
