What would it take to secure BGP? Let’s begin where any engineering problem should begin: what problem are we trying to solve? This series of posts walks through a wide range of technical and business problems to create a solid set of requirements against which to measure proposed solutions for securing BGP in the global Internet, and then works through several proposed solutions to see how they stack up.
Post 1: An introduction to the problem space
Post 2: What can I prove in a routing system?
Post 3: What I can prove in a routing system?
Post 4: Centralized or decentralized?
Post 5: Centralized or decentralized?
Post 6: Business issues with centralization
Post 7: Technical issues with centralization
Post 8: A full requirements list
Post 9: BGPSEC (S-BGP) compared to the requirements
Post 10: RPKI compared to the requirements
I will continue updating this post as I work through the remaining segments of this series.

The moment an IETF working group agrees on a protocol someone starts creating extensions. PCEP is no exception; in the last part of the BGP-LS and PCEP webinar Julian Lucek talked about some of them.
In this episode, Ethan Banks sat down with network architect Russ White for a live interview about the current state of the network, emerging trends such as SDN and open networking, and why we need more protocols instead of fewer.
The post Show 288: The Future Of Networking With Russ White – Recorded Live appeared first on Packet Pushers.

We collect the top expert content in the infrastructure industry and fire it along the priority queue.
Two weeks ago CloudFlare announced that it was supporting HTTP/2 Server Push for all our customers. By simply adding a Link header to an HTTP response specifying preload CloudFlare would automatically push items to web browsers that support Server Push.
To illustrate how easy this is I create a small PHP page that uses the PHP header function to insert appropriate Link headers to push images to the web browser via CloudFlare. The web page looks like this when loaded:

There are two images loaded from the same server both of which are pushed if the web browser supports Server Push. This is achieved by inserting two Link headers in the HTTP response. The response looks like:
HTTP/1.1 200 OK
Server: nginx/1.9.15
Date: Fri, 13 May 2016 10:52:13 GMT
Content-Type: text/html
Transfer-Encoding: chunked
Connection: keep-alive
Link: </images/drucken.jpg>; rel=preload; as=image
Link: </images/empire.jpg>; rel=preload; as=image
At the bottom are the two Link headers corresponding to the two images on the page with the rel=preload directive as specified in W3C preload draft.
The complete code can be found in this gist but the core of the code looks like this:
<?php
function pushImage($uri) {
header("Link: <{$uri}>; rel=preload; Continue reading
