Community Show – The Rash Came Back After 19 Hours
While Packet Pushers were covering the Barcelona HP Discover conference and we got together with some of the folks attending the event on the show floor. The result is non-coherent discussion about whatever topics each person wanted to raise and discuss.

A Single Architect for Your Network
I finally got around to reading The Mythical Man Month (MMM), a famous book on large-scale software development projects (think operating systems) written in 1975, revised in 1995, and still strikingly relevant today in the neighboring field of building and managing massive networks. While multiple points land directly on those of us working on massive […]

BGPSEC: Replays, Timers, and Performance
Let’s return to our simple four AS network to look at a number of issues with BGPSEC — the bits you won’t often hear discussed in just about any forum. Assume, for a moment, that AS65000 advertises some route, say 192.0.2.0/24, to AS65001, and not to AS65002. For whatever reason, a few days pater, the […]

Show 218 – OSPF Design Part 2
A long time ago, Packet Pushers ran an OSPF Design Part 1 show. That show went after the default design guides that network engineers have been reading for years, making the big point that you can scale a single OSPF area quite large indeed. But…that’s not the entire story about OSPF areas. Areas still have their use cases, […]

Policy-based Tunnel Selection (PBTS) on Cisco IOS-XR
Recently, I had to look after PBTS on Cisco ASR9K platform and faced some issues, here are some results about my tests. PBTS has the same goal as CBTS on Cisco IOS (Class-Based Tunnel selection) but for Cisco IOS-XR. It provides a tool to direct traffic into specific RSVP-TE tunnels (in the future Segment-Routing tunnels) […]

HTIRW: Standards Bodies
(yes, I know, it’s been a while… But it’s time to get back to this series) Up to this point in this series, we’ve been discussing the more technical aspects of how the Internet really works. Now I want to shift gears a little, and talk about some of the more political aspects — standards […]

Show 217 – IETF, YANG Proliferation and the Lack of Cooperation and Co-ordination
This week are talking about the IETF and it's inability to cope with massive change in networking around SDN and NFV. For example, there are more than 70 drafts on NETCONF models for common networking tasks that often overlap or repeat the same work. What does this means for standards development ?

BGPSEC: Protections Offered
In my last post on the subject of BGPSEC, I explained the basic operation of the modifications to BGP itself. In this post, I’ll begin looking at some of the properties — both good and bad — of these extensions to BGP. To being, we’ll look at the simple network illustrated here, and see what […]

RPKI: BGP Security Hammpered by a Legal Agreement
Resource Public Key Infrastructure (RPKI) is a relatively new standard for establishing BGP route origination. I wrote a brief introductory article here. Apologies for the self-promotion, but rather than rehash the basics here, I raise another issue that needs community attention: ARIN’s Relying Party Agreement (RPA: PDF link). Having said that, some basics are needed. […]

The Attributes of a Great Network Device API
What makes a good API? A device providing an API is only the start of the story; if its unusable, or unreliable its useless. This post is a response to one of a couple of points I made about Kirk Byers’ recent post on Arista’s API and the comments that followed. Much respect to (and admiration for) Arista […]

Guests Needed for Design + Build 2015 Podcasts
Updated 12-January-2015 to include survey form. I’m working on a series of “design and build” podcasts in 2015 for Packet Pushers. The idea is to take a network protocol, project, business challenge, reference architecture, etc. and talk through the why and how. Are you willing to be a guest to share your real-world experience? I’d […]

Show 215 – SDN Training & Certifications with Wendell Odom
Software defined networking (SDN) has arrived in the form of vendor released products. If you follow this show, you know that these products are largely incompatible. Certainly there’s no “one size fits all” when it comes to SDN technologies today. In SDN’s awkward tween years, what are network engineers trying to stay current to do? […]
