Recommended Networking Resources for September 2019 Second Week

There are so many good resources for Network Engineers out there. I started to share the ones I liked last week.

Click here to see September 2019, First Week Networking Recommended Resources.

As you know, I will share 5 resource every week. There are so many in my list already, I can’t wait for the next week to share next recommended 5 resources!

Let’s start.

  1. This post is explaining the basics of Active-Active Datacenter concept.

2. BGP Information Security is very important to secure Global Internet. Origin Validation can be done in two ways, IRR and RPKI, Networks can have both at the same time. Below post explains RPKI (Resource Public Key Infrastructure) in very good detail.

3.  BIER (Bit Indexed Explicit Replication) is very cool new tool for scalable IP and MPLS Multicast Design. When I explain it in few words, I say, Segment Routing removes the requirement of LDP and RSVP for Transport LSP in MPLS, BIER does the same thing for Multicast Traffic. You don’t need PIM, mLDP etc.

Below Packet Pusher podcast is all about BIER and couple other cool Datacenter specific Routing protocols (RFC 7938 type of Datacenter routing protocol) RIFT and BGP+SFC.

4. Is IPv6 faster than IPv4? Let’s try to understand what are the considerations IPv4 or IPv6 can be faster. Below APNIC post have some good statistics as well.

Why is IPv6 faster?

5.  We have Flat Internet concept. Many large ASes exchange traffic in either Private or Public Peering with each other directly. Those networks are directly connected and their traffic is just one hop away. This effectively reduces average AS-Path length to 4 in Global Internet Routing Table (Commonly known as DFZ- Default Free Zone).

Below research paper is explaining with a great analysis about Flat Internet paradigm and how networks are just one hop away mostly in today Internet.
