- 18. 18 What Neutron may lack in certain large cloud environments • “Core” and “Service” plugins provide many networking funcNons, but may lack advanced features such as: • Service Chaining (L2-Transparent, L3, Hybrid) • PNF + VNF Service Chaining • Dynamic rouNng (BGP/MPLS) • Distributed Source Network Address TranslaNon (SNAT) • Real-Nme and historical analyNcs • Scalability • Performance • High Availability • Cannot manage physical network devices (bare metal)
- 20. 20 Augmenting Neutron with Juniper Contrail
- 21. 21 How Contrail Networking Augments Neutron • Built for scaling in large production environments • Able to handle large number virtual networks • Superior transactional scale • Improved server performance over OVS • Can handle large number of transaction requests • Designed to perform at scale • Supports ISSU for easier management • Supports inter-version compatibility • Multi-tenant VN micro- segmentation • Service chaining • Advanced analytics • Underlay visibility • LBaaS and other services • Easy to troubleshoot SCALE PERFORMANCE HA RESILIENCE NETWORK FEATURES Contrail Networking is industry leading in all 4 areas

- 25. 25 Tier 1 Telco Case Study - vCPE through a NaaS model • Telco wanted to become a sohware/cloud company by launching a network-as-a- service (NaaS) offering for mulNnaNonal customers in many countries • In the past, a new service like an enterprise firewall, would typically take 2-3 months and cost a lot money • With NaaS, Telco ships their customer an x86 server, which the customer simply plugs in for Internet access, and is configured to be self-installed, within minutes. • Includes firewall, web content protecNon, URL filtering, and malware defense. Time-to-market is greatly reduced, and service automaNon and virtualizaNon have driven down operaNonal costs.
- 26. 26 Tier 1 Telco Case Study - vCPE through a NaaS model Business Challenge NaaS Solu3on : SDN/NFV based vCPE service 1. Reduce time to add new services using appliance based services on top of traditional MPLS based architecture 2. Enterprise customers require greater agility, speed, and simplicity 1. Replace appliance based services with virtualized services § Fast deployment 2. Customer self-care portal to control network policies (QoS, routing, security) § Fast provisioning [no ticket to support team need for config changes] § Rapid delivery - automation of the internal processes 3. New innovative network products § Enabling customized service chaining to allow processing of traffic network infrastructure

- 29. 29 Challenges and Lessons Learned • Open source drives innovation and freedom of choice • Standard Neutron with OVS may not good enough for some networks – Contrail augments OpenStack networking very nicely – Rich networking features L3VPN and SFC versus OVS • Project planning and good communication are critical – have a well defined process and understand who is doing SI – Make OSP and SDN decision together – Select SDN and OSP solutions that are certified • Sales and deployment cycle is long and complex – Cross train and cross test, especially when new to OpenStack
