My passion in life is learning and I'm always learning something new. My primary focus is network architecture for service provider and enterprise data centers.

Breaking down complex problems into simple building blocks and coming up with elegant, simple solutions is very rewarding and I love doing it.

Clos IP Fabric with QFX5100 Switches(Link)

Juniper Networks
April 2014

This paper describes how to build large IP fabrics using QFX5100 switches. This paper is written by network engineers for network engineers and covers why you would want to build a Clos IP fabric and how to build, configure, and verify Clos IP networks using the QFX5100 Switch. Example configurations are included, enabling you to architect and configure your Clos IP network based on the examples.

Multi-Stage Clos Architectures(Link)

February 2014

As overlay networks in the data center become more common place, everyone is trying to build the best possible underlay using CLOS fabrics. A key issue with large 5-stage CLOS fabrics are the provisioning and management. This presentation proposes a method to simply the management of a 5-stage CLOS fabric by collapsing three stages into a logical entity called a vSpine. By creating a multi-stage CLOS using a vSpine in the middle stage, it effectively reduces the operational overhead of a five-stage CLOS down to a three-stage CLOS, but with the benefit of having the scale of a five- state CLOS.

Juniper MX Series: A Comprehensive Guide to Trio Technologies on the MX(Link)

O'Reilly Media
October 2012

Discover why routers in the Juniper MX Series, with their advanced feature sets and record breaking scale, are so popular among enterprises and network service providers. This authoritative book shows you step-by-step how to implement high-density, high-speed Layer 2 and Layer 3 Ethernet services, using Router Engine DDoS Protection, Multi-chassis LAG, Inline NAT, IPFIX/J-Flow, and many other Juniper MX features.

Scaling Beyond a Single Juniper SRX in the Data Center(Link)

Juniper Networks
April 2012

When you can no longer upgrade to a higher capacity firewall, or add additional Service Processing Cards (SPC), the only other choice is to scale horizontally. Day One: Scaling Beyond a Single Juniper SRX in the Data Center elegantly addresses the problem and provides unique insight into how to provide security to outbound traffic at levels that can scale to meet the needs of even the largest networks. Follow along with this proof of concept and get the configuration for doing so at the end.

Securing the Routing Engine on the M, MX and T Series(Link)

Juniper Networks
June 2011

The routing engine on Junos routers performs many different functions, from processing routing protocol updates, to driving the command-line interface (CLI). Given that the routing engine is critical to the operation of the device and its network, you need to protect the routing engine from unwanted traffic by allowing only essential permitted traffic. Unwanted traffic can come in many different forms: malicious traffic seeking to gain unauthorized access, unintentional routing protocol updates from neighboring devices, or even legitimate traffic that exceeds a given bandwidth limit.
