For some time I have had issues while doing captures such as finding the elusive “spare laptop” you can use, multiple trips out to the site to pick up the captures, or finding another NIC to put in there so you can connect remotely and copy the captures over the network, taking up 2 switch […]

Curt Beckmann, CTO for EMEA at Brocade, joins Packet Pushers Ethan Banks & Greg Ferro for an update of what’s been going on with the Forwarding Abstractions Working Group (FAWG) at the Open Networking Foundation (ONF). We get into a discussion of emerging Table Type Patterns within OpenFlow (OF), a way for OF switches and OF […]

So far, we’ve looked at the naming system, routing, and policy in our travel through “internet land.” Last time, we took a quick look at some of the various organizations that create the standards that make the internet work. This time I’m going to start looking in more depth at one specific standard body, or […]

I’ll admit it – I’ve drunk the “Network Engineers should learn programming” Kool-Aid. In so doing, I’m gearing up for Kirk Byers upcoming “Python for Network Engineers” course by hacking a bit of Python most every evening. Kirk has recently released a Python “wrapper” module for the popular Python SSH module “Paramiko” that simplifies connections […]

This is a continuation of the sponsored series of shows we recorded at the HP Discover Barcelona conference in December 2014. An interesting facet of HP Discover to me was meeting smart HP folks at random. Sue Darte is such a person I was lucky enough to bump into. Here’s the story. While waiting to record a […]

Here’s an update on some Packet Pushers news, and a look ahead to the content we’re planning for 2015. No scary announcements, just some thoughts to share. Circling Back Around On Show 200 I think we’ve mentioned it before, but the response we received to show 200 was very encouraging to us. That’s understated. You really blew […]

BGPSEC is a set of BGP extensions being developed by the SIDR working group of the IETF to improve the security of the Internet’s routing infrastructure. So far in this series, we’ve looked at the basic operation of BGPSEC, the protections offered, and then the first set of performance issues — how do we prevent […]

Ben Pfaff, Justin Pettit, and Ethan Jackson are core contributors to the Open vSwitch (OVS) project. What’s OVS? OVS is a virtual switch that’s growing in popularity as an open source vSwitch. The more you dig into open source networking projects, the more you see OVS showing up. One of the OVS gotchas in the past has […]

I’ve always advised my clients to carefully plan the implementation of IPv6. The protocol opens new attack vectors on which ne’er-do-wells can assault your infrastructure. There are countless examples I’ve seen such as service providers locking down access to routers using IPv4 transport but leaving IPv6 transport completely open. About a year ago, I stumbled […]

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 […]

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 […]

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, […]

HP Helion is the cloud platform HP is bringing to Enterprise for private cloud and used by HP to build their Helion public cloud. In this show, recorded at HP Discover as part of our show coverege, we talk about Virtual Cloud Network (VCN) for OpenStack that uses OpenFlow and OVSDB as a basis for implementing features in the physical network in OpenStack and Helion.

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) […]

(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 […]

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 ?
