Service Provider requirements for DevOps

• increased network stability• optimize for larger transmission delays

• scalability to millions+ sessions with less hardware• adapt to diversity of resource programmability

• extend existing procedures to new resource and service classes

• common APIs for workflow orchestration and automation

The UNIFY SP-DevOps Toolkit

• Is• Inspiration for the telecom DevOps community for new features• A collection of research results released under individual licenses• Provided as-is, with no guarantees• Supported by the respective authors best efforts

• Is not• Production-ready• Optimized for all potential use cases

DoubleDecker: a message bus for all

• Scalable communication services for monitoring functions and/or VNFs

• IP (unicast, multicast) and IPC transport• Pub-sub and direct communication pattern

• Extends ZeroMQ with• Client and broker hierarchy with heartbeat• Simple routing mechanism• Isolation mechanism for multi-tenancy with

built-in encryption key management• https://github.com/acreo/doubledecker

VES

EPOXIDE: debug with Emacs

• Troubleshooting framework integrating other tools in TroubleShooting Graphs (TSG)

• Based on EMACS• Nodes and links of TSG are shown in

buffers• semantic navigation• navigation in a visualized TSG

• Event driven framework• API for third-party tool developers• http://github.com/nemethf/epoxide

Pinpoint Doctor

RateMon: instant congestion prediction

• Scalable congestion detector based on reading switch port utilization counters

• Uses first and second statistical moments for link utilization

• transmits only the estimate to the controller, instead of high-speed data flow

• 1-minute prediction with message rate 3000x lower than raw SNMP counters

• https://github.com/nigsics/ramon.git

Software Fastpath Service Quality MetricsPrediction

VeriGraph: fast pre-deployment verification

• Check properties of deployment models (currently, using UNIFY VNFFG format)

• Topological reachability• Isolation• Node traversal

• Based on the Z3 SMT solver, a formal methods satisfiability tool
