2. Agenda
• Enterprise Workplace and Data Center Networking Trend
• Arista Networks Introduction
• Arista Datacenter Solution
• Arista and Aruba joint SDN Solution

3. Campus Networking Trends
• Wireless will be pervasive with BYOD
• Reduction in wired ports/interfaces
• Major shifts in end point applications
• Cloud drives large file exchanges
• Peer to peer video sharing requires 4-10X increases
• VDI drives low latency, fast interaction with servers
• Authentication, mobility, resource control
•
Point to centralized models -> controllers

4. Campus Bandwidth Drivers

5. Aruba and Arista
Aruba delivers the best wireless solution
• Aruba’s leads technically with AP technologies !
• Aruba offers POE switch line for AP, and wired access!
• SDN is an extension to Aruba’s WLAN controller approach!
Arista’s SDN switches - great extension to this design
• Arista leads technically in 10/40/100 Gbps switching!
• Arista offers best power/rack footprint !
• SDN is an extension to EOS, current and future platforms

49. Growing Need for SDN Architectures
• Centralized Campus Controllers for:
• Authentication, authorization with directory services
• Controlled access to resources (Apple TV)
• IP Mobility with voice, video hand offs
• Data path switching “offload” for:
• Reducing minimizing choke points
• For best path optimization, bandwidth and redundancy
• For reducing cost of controller (X86 appliance, No Fast Path)

51. OpenFlow Support
• OpenFlow support has been added to
Arista EOS
• Arista has tested Openflow support on
the 7050 Series with multiple controller
vendors and projects- Big Switch, NEC,
Floodlight, etc.
• Arista is the most controller-friendly
switching platform – with tested support
for multiple controllers
Controller
OpenFlow
Protocol

52. DirectFlow Control
• Enables direct CLI and eAPI control
over specific flow switching
operations
• Extends the capabilities of OpenFlow
with controller-less operation and
enables per-flow pattern-matching
with full control
• Enables firewall load balancing,
special case path selection, etc.

55. EOS API – Programmatic Access to EOS
• Provides programmatic access to all system configuration
and status available in the CLI
• Requests to read & write state use the existing CLI command
• Requests are sent using JSON-RPC over HTTPS
• Response is a structured JSON object
• Differentiation over competition - open and complete client interfaces
