SERVER VIRTUALISATION
• More choices of hypervisors
• Rich and new embedded “Networking” functions in software
• New trend with “light” containers (LXC with Dockers)
• Software abstraction layer (from server hardware)
• Divide one physical server into multiple isolated
virtual environments
• Vmware integration with ESXi (ND) & NSX overlays
• Plugins to Junos and Juniper Overlay for
Openstack/Cloudstack

Market Share Q2 2013
NETWORK VIRTUALISATION
• From hype to real deployment
• New paradigm for Cloud & NFV
• Network Virtualization creates logical, virtual networks (and
network functions) that are decoupled from the underlying
network hardware
• Overlay vs Underlay
• NSX partner
• Juniper solution for Openstack/Cloudstack with Contrail

Challenge
Downtime not acceptable during software
upgrades. Legacy/competitive solutions need the
support of adjacent devices during software
upgrade.
Solution
Topology-independent ISSU – Made possible by
QFX5100’s unique software architecture.
Benefits
No traffic loss during upgrades
No port flap during upgrades
Works in any switching architecture

Real-time Buffer Utilization
Monitoring And Reporting
High Threshold
Low Threshold
Microburst
Challenge
Traditional analytics sample at very low frequency
~1-5 seconds. It misses critical events that may
disappear within this time interval. Network is
exposed to hotspots due to events like microbursts.
Solution
Insight Technology – Samples every 8ms
Benefits
Provides real time visibility of network hotspots
(microburst levels)
Enables correlation of historical events and
creates file in multiple formats
Enables admin to circumvent hotspots and
proactive move workloads smartly
INSIGHT TECHNOLOGY
WHY MICROBURST MATTER?Switch dropping traffic without you knowing it
5 millisecond view Congestion Threshold exceeded
Finer Granularity

due to Microbursts
Congestion Threshold not exceeded1second view
5 Minute ViewLegacy Traffic View
Misses the problem
ANALYTICS SOLUTION WITH QFXInsight Technology
• Reports the microburst event when it occurs
• Queuing statistics collection:
• Queue depth in bytes (high/low threshold)
• Queue latency in nanoseconds (high/low threshold)
Buffer utilization monitoring and reporting
• End to End System Traffic Collection & Reporting
• Streaming captured data in open standards protocols
High frequency Traffic Statistics
• QFX5100, 3500 & 3600
