In this Tech Field Day presentation recorded on February 15, 2013, Sean Rhea delves into the backend architecture of Meraki’s cloud-based Dashboard. Rhea, who joined Meraki in 2007 and became the head of the backend scalability performance team in 2010, explains the tools and systems that enable Meraki to rapidly develop and deploy new features. The presentation focuses on the cloud architecture, which partitions customers into shards, each managed by a 1U server with redundancy across different data centers and providers. This setup ensures high availability and reliability, even in the event of a data center failure. The master shard acts as a demultiplexer, directing users to the appropriate shard for their data, while the system handles massive multi-tenancy with thousands of Meraki devices checking in every 45 seconds.

Rhea introduces the M-Tunnel system, which facilitates communication with Meraki devices even behind NATs, ensuring efficient data collection and configuration management. The M-Tunnel system is a resilient overlay network that reroutes traffic among shards if direct communication fails. This system, combined with the high-frequency data collection, presents significant challenges in terms of network communication and data storage. To address these, Meraki developed POTR, a high-performance system for gathering statistics. POTR uses an event-driven RPC engine with non-blocking I/O and Google protocol buffers, significantly reducing network and CPU overhead. This system allows Meraki to collect data every 45 seconds, providing high-resolution insights into network performance and issues.

The presentation also covers Little Table, a custom database designed to handle the vast amounts of data collected by Meraki devices. Little Table uses ordered trees and fixed-size buffers to efficiently store and retrieve data, minimizing disk seeks and maximizing throughput. This system allows Meraki to store detailed statistics for extended periods, enabling deep analytics and feature development. By maintaining high-resolution data, Meraki can offer detailed insights and historical analysis, which is crucial for both troubleshooting and developing new features. The presentation concludes with a discussion on the importance of data security and compliance, particularly for customers in regions with stringent data protection regulations, such as the EU.

Cisco Update on the Meraki Acquisition with Sanjit Biswas

Personnel: Sanjit Biswas

Meraki Co-Founder and CEO, Sanjit Biswas, updates the Wireless Field Day 4 delegates on Cisco’s recent acquisition of his company. Sanjit discusses Cisco’s plans for the Meraki product line as well as the future of the cloud-managed platform at Meraki and within Cisco and rumors of a tie-in with Cisco’s divestment of Linksys. Meraki has a new building in San Francisco and is building new products. Delegates ask about cultural change within Meraki, the value of Meraki’s “make a wish” user interface for direct feedback, the future of Meraki’s product line, and international plans.

Personnel: Keith Parsons

How does a Wi-Fi engineer do his job? In this roundtable discussion, the Wireless Field Day 4 delegates discuss their favorite tools.

Casual tools: NetStumbler, MetaGeek inSSIDer

Predictive Survey tools: Ekahau Site Survey, AirMagnet Survey, Motorola LANPlanner, Cisco WCS

Discovery tools: AirMagnet Survey, WildPackets OmniPeek, AirMagnet WiFi Analyzer, MetaGeek inSSIDer, Fluke AirCheck

The Survey Process and Post-Install Validation surveys (AP on a Stick): Ekahau Site Survey, AirMagnet Survey, TamoSoft TamoGraph Site Survey

Tip: Install AirMagney Survey on a dedicated machine (or in a virtual machine), run it on an SSD, and make sure there is lots of RAM

Packet Analysis and Troubleshooting: Wireshark, MetaGeek AirPcap for data capture

Costing tools: OmniPeek, AirMagnet WiFi Analyzer

AirPcap Tip: The internal NIC on a Mac sometimes outperforms the AirPcap device
