Datacenter Networking Trends •  Expansion of Web / Cloud Data Centers

–  Leaf-Spine scale to support East-West traffic –  High density racks require more bandwidth –  10G virtualized workloads driving 40G / 100G –  IP-based storage –  Predictable and low latency

•  Software Defined Networks –  Virtualization for networks –  Real-time programmability and monitoring –  Operational excellence –  Extensible Open APIs

•  Big Data Growth –  Scaling Network Attached Storage to accommodate expanding

unstructured data –  High performance Hadoop workloads for BI and analytics

http://www.arubanetworks.com/pdf/TR_AristaInteroperability.pdf

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)

①  Seamless WLAN overlay deployment ②  Broadcast/Multicast arbitration for WLANs ③  Centralized controller based flow control

①  “AirGroup” mDNS centralized control plane ②  Abstract underlying L2/L3 network topology ③  Basic Interoperability with campus aggregation

layer (Arista) via SDN ①  Extend AirGroup constructs to Wired ②  Application specific traffic offload to network

elements (Arista in aggregation) via SDN ③  Centralized arbitration point for network,

services discovery protocols

•  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

OpenFlow Protocol

OpenFlow Support

•  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.

•  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
