This Week: An Expert Packet Walkthrough on the MX Series 3D

This Week: An Expert Packet Walkthrough on the MX Series 3D provides the curious engineer with a global view of the short life (a few milliseconds) of packets inside the Juniper Networks MX Series of 3D routers. While it may be a short life inside the router, the packets are processed by an amazing ecosystem of next generation technology. Sit back and enjoy a network engineering book like no other as you travel inside the MX Series 3D.

Author Q & A

What got you started on this book?

For several years, I spent a lot of time to better understand how packets are handled by Juniper HW. I started by analyzing packet walkthrough on LMNR architectures, then IChip based chipset and finally on the awesome Trio architectures. I would like to share my amazing reverse engineering "game" with the network community.

Who is this book for?

This book is for people that want to clearly understand how a packet is managed by recent routers. The book doesn't rely on complex network topology but nevertheless it requires good Junos skills.

After reading this book, what's the take away?

After reading you should better understand how packets are managed by Juniper recent HW. You could customize and tune the configuration of the router for better security and scalability.

What are you hoping that people will learn from this book?

People will learn how CoS and Control plane protection are implemented on Juniper HW. Moreover, I give some methods or processes to better troubleshoot routers.

What do you recommend as the next item to read after this book?

Reading the O'Reilly MX book and play in the lab ☺

What's your inspiration?

My inspiration is my job day after day. I'm a NOC engineer. Every day I need to know exactly and deeply how our customer traffic is managed by our routers (not only the Juniper one).

What's your favorite bit/part in the book?

My favorite part is the how control packet are handles by Juniper HW and especially how Junos secures its resources against DDOS attacks.
