Rough Guide to IETF 100: Internet Infrastructure Resilience

As we approach IETF 100 in Singapore next week, this post in the Rough Guide to IETF 100 has much progress to report in the world of Internet Infrastructure Resilience. After several years of hard work, the last major deliverable of the Secure Inter-Domain Routing (SIDR) WG is done – RFC 8205, the BGPSec Protocol Specification, was published in September 2017 as standard. BGPsec is an extension to the Border Gateway Protocol (BGP) that provides security for the path of autonomous systems (ASes) through which a BGP update message propagates.

There are seven RFCs in the suite of BGPsec specifications:

  • RFC 8205 (was draft-ietf-sidr-bgpsec-protocol) – BGPsec Protocol Specification
  • RFC 8206 (was draft-ietf-sidr-as-migration) – BGPsec Considerations for Autonomous System (AS) Migration
  • RFC 8207 (was draft-ietf-sidr-bgpsec-ops) – BGPsec Operational Considerations
  • RFC 8208 (was draft-ietf-sidr-bgpsec-algs) – BGPsec Algorithms, Key Formats, and Signature Formats
  • RFC 8209 (was draft-ietf-sidr-bgpsec-pki-profiles) – A Profile for BGPsec Router Certificates, Certificate Revocation Lists, and Certification Requests
  • RFC 8210 (was draft-ietf-sidr-rpki-rtr-rfc6810-bis) – The Resource Public Key Infrastructure (RPKI) to Router Protocol, Version 1
  • RFC 8211 (was draft-ietf-sidr-adverse-actions) – Adverse Actions by a Certification Authority (CA) or Repository Manager in the Resource Public Key Infrastructure (RPKI)

Lunduke’s Theory of Computer Mockery — no technology is sacred

“Any sufficiently popular, or important, computer technology will be mercilessly mocked 20 years later.” I call that Lunduke’s Theory of Computer Mockery. (Yes, I named it after myself. Because… why not?)The more important the technology, the more ruthlessly and brutally it will be mocked. It helps if the technology was, itself, a bit flawed when new. But even when a piece of tech is well received initially, 20 years later it will be fully brutalized. Let’s take a look at some examples: Windows 95  Would you use Windows 95 in 2017? Of course not. Would you make fun of it without regard for its feelings? Of course you would. To read this article in full or to leave a comment, please click here

Fujitsu, NetApp partner for hyperconverged systems

Smaller players in the IT hardware space can often be overlooked because dominant players cast such a long shadow. So as someone who roots for the underdog, I do enjoy shining a little light on an overlooked bit of news.Fujitsu is not the first name in data center hardware here in the U.S. Its primary place of business is its native Japan. For example, it built the RIKEN supercomputer, one of the 10 fastest in the world. But it has some good hardware offerings, such as its Primergy and Primequest server line. Well, now the company has partnered with NetApp to offer them converged and hyperconverged systems.Also on Network World: Hyperconvergence: What’s all the hype about? Converged and hyperconverged infrastructure (CI/HCI) is a fancy way of saying tightly integrated systems that combine compute, networking and storage into pre-tested and pre-configured stacks for a single turnkey solution rather than buying and assembling one.To read this article in full or to leave a comment, please click here

A glance back at the looking glass: Will IP really take over the world?

In 2003, the world of network engineering was far different than it is today. For instance, EIGRP was still being implemented on the basis of its ability to support multi-protocol routing. SONET, and other optical technologies, were just starting to come into their own, and all optical switching was just beginning to be considered for large scale deployment. What Hartley says of history holds true when looking back at what seems to be a former age: “The past is a foreign country; they do things differently there.”

In the midst of this change, the Association for Computing Machinery (the ACM) published a paper entitled “Will IP really take over the world (of communications)?” This paper, written during the ongoing discussion within the engineering community over whether packet switching or circuit switching is the “better” technology, provides a lot of insight into the thinking of the time. Specifically, as the author say, the belief that IP is better:

…is based on our collective belief that packet switching is inherently superior to circuit switching because of the efficiencies of statistical multiplexing, and the ability of IP to route around failures. It is widely assumed that IP is simpler than circuit Continue reading

Can Wave 2 handle the wireless tsunami heading toward us?

There seems to be a shift in our industry from wireless N to AC, as we have seen large leaps forward in bandwidth and client saturation handling. With more wireless options going in the workplace, widespread connectivity continues to rise and wireless requirements are becoming greater and greater.Now, with Wave 2 becoming more common, is AC really able to handle the tsunami-like wave of wireless internet requests to meet this growing demand?Also on Network World: REVIEW: Early Wave 2 Wi-Fi access points show promise There's only one way to find out. We need to step out of the comfort zone provided by past wireless technologies and expand the idea of what wireless is capable of providing to meet these demands.To read this article in full or to leave a comment, please click here

Worth Reading: Should we trust geolocation?

Geolocation databases are often used by both researchers and network operators to learn the real-world location of a given IP address. But how reliable are these in terms of coverage and accuracy at both country- or city-level resolutions? Evaluation studies of previous geolocation databases are dominated by the results over end-host addresses. As a result, the users are left unsure about the reliability of geolocation databases over infrastructure IP addresses such as those of router interfaces. –Manaf Gharaibeh @ APNIC
