Reaction: Mend, don’t end, the IETF

Is it time for the IETF to give up? Over at CircleID, Martin Geddes makes a case that it is, in fact, time for the IETF to “fade out.” The case he lays out is compelling—first, the IETF is not really an engineering organization. There is a lot of running after “success modes,” but very little consideration of failure modes and how they can and should be guarded against. Second, the IETF “the IETF takes on problems for which it lacks an ontological and epistemological framework to resolve.”

In essence, in Martin’s view, the IETF is not about engineering, and hasn’t ever really been.

The first problem is, of course, that Martin is right. The second problem is, though, that while he hints at the larger problem, he incorrectly lays it at the foot of the IETF. The third problem is the solutions Martin proposes will not resolve the problem at hand.

First things first: Martin is right. The IETF is a mess, and is chasing after success, rather than attending to failure. I do not think this is largely a factor of a lack of engineering skill, however—after spending 20 years working in the IETF, there Continue reading

DNS Glitch

Had a DNS glitch mid morning ET in switching some configurations around. It should be back up and running now, and rule11.tech should be coming up as a secondary domain soon’ish.

Worth Reading: ONIE in the Data Center

ONIE stands for Open Networking Install Environment; it allows a network operating system (NOS) to be installed on any white-box switch hardware that supports this technology. Essentially it’s an extremely lightweight Linux implementation that is put on the mass-storage device in the switch during the manufacturing process, enabling automation of discovery and installation of a NOS image once installed on the customer network. ONIE supports installation from a variety of sources over a network using IPv4, IPv6 and tFTP, or even locally from a USB flash drive. Not only does this technology ease data center administration, it gives the end user a broader choice in software and hardware combinations. —Data Center Journal

Worth Reading: Intel Defends Chip Innovation

With absolute dominance in datacenter and desktop compute, considerable sway in datacenter storage, a growing presence in networking, and profit margins that are the envy of the manufacturing and tech sectors alike, it is not a surprise that companies are gunning for Intel. They all talk about how Moore’s Law is dead and how that removes a significant advantage for the world’s largest – and most profitable – chip maker. After years of this, the top brass in Intel’s Technology and Manufacturing Group as well as its former chief financial officer, who is now in charge of its manufacturing, operations, and sales, pushed back today with its first event dedicated explicitly to its chip factories and the processes they use to etch devices. —The Next Platform

Openfabric: A Short Video of the IETF Presentation

The most current version of the draft can be found here. There is one more comment from Uma that still needs to be addressed, and one more section that needs to be added. There will probably be more changes, as well, over time. These sorts of drafts do not happen through one person; a number of folks have worked on various bits of the draft, including Shawn, Nikos, Ivan, Les, Naiming, Uma, and others—the folks who have added ideas, etc., are included in the contributors section, which is always worth paying attention to!

Worth Reading: A Case to Further Registrar Self Regulation

In most industries, businesses that blatantly act against the interests of their customers to favor their own internal profit centers would either not be allowed or else subject to controls and oversight by the government. It is universally regarded as an unfair and deceptive business practice. In the domain name registrar business, however, the normal practices of legitimate business dealings and customer protection seem woefully wanting. Kelly’s Case described here illustrates the point, and it provides the opportunity for ICANN to demonstrate it can be responsive to egregious registrar behavior without government agencies or juridical bodies becoming engaged. —CircleID

Worth Reading: Security Orchestration and Incident Response

Last month at the RSA Conference, I saw a lot of companies selling security incident response automation. Their promise was to replace people with computers ­– sometimes with the addition of machine learning or other artificial intelligence techniques ­– and to respond to attacks at computer speeds. While this is a laudable goal, there’s a fundamental problem with doing this in the short term. You can only automate what you’re certain about, and there is still an enormous amount of uncertainty in cybersecurity. Automation has its place in incident response, but the focus needs to be on making the people effective, not on replacing them ­ security orchestration, not automation. —Schneier on Security

Worth Reading: Microservices to the Edge

There’s a hidden tension here. Once you put code at the edge you violate two of Lambda’s key assumptions: functions are composed using scalable backend services; low latency messaging. The edge will have a high latency path back to services in the datacenter, so how do you make a function based distributed application at the edge? Does edge computing argue for a more retro architecture with fewer messages back to a more monolithic core? —High Scalability

Worth Reading: IPAM and RIRs

In terms of the strategy surrounding IPAM, most of the thinking was focused on a ‘downward’ approach, in as much as you define a pool of IP addresses and the role of IPAM is to manage its application to devices and systems in your network: configure bindings to customer accounts, billing, assign maps between device identifier and IP, size pools to reflect DHCP requirements, and configure the CGN. —APNIC

On the ‘net: CAP and SDN

The CAP theorem essentially states that consistency, accessibility, and portioning are three sides of a tradeoff triangle. Much like quick, cheap, and quality; or state, optimization, and surface; CAP posits that you can choose “two out of three.” To illustrate, it is often helpful to consider a database in various stages of being partitioned, and consider the impact on consistency and accessibility, the other two sides of the triangle. The figure below will be used as a reference. —ECI

Worth Reading: Botnets in the Cloud

The arms race between data security professionals and cybercriminals continues at a rapid pace. More than ever, attackers exploit compute resources for malicious purposes by deploying malware, known as “bots”, in virtual machines running in the cloud. Even a conservative estimate reveals that, at least, 1 in every 10,000 machines are part of some known Botnet. —Azure Blog

Worth Reading: QoS Marking is an Application Problem

I was so delighted to hear someone finally realized how to handle QoS properly: the responsibility lies with the applications on the host; the network should just provide what it was asked to do, not try to reverse-engineer application intent based on TCP/UDP port numbers or haruspicy. —IPSpace

Distributed Denial of Service Open Threat Signaling (DOTS)

When the inevitable 2AM call happens—”our network is under attack”—what do you do? After running through the OODA loop (1, 2, 3, 4), used communities to distribute the attack as much as possible, mitigated the attack where possible, and now you realist there little you can do locally. What now? You need to wander out on the ‘net and try to figure out how to stop this thing. You could try to use flowspec, but many providers do not like to support flowspec, because it directly impacts the forwarding performance of their edge boxes. Further, flowspec, used in this situation, doesn’t really work to walk the attack back to its source; the provider’s network is still impact by the DDoS attack.

This is where DOTS comes in. There are four components of DOTS, as shown below (taken directly from the relevant draft)—

The best place to start is with the attack target—that’s you, at 6AM, after trying to chase this thing down for a few hours, panicked because the office is about to open, and your network is still down. Within your network there would also be a DOTS client; this would be a small piece of software running Continue reading

Worth Reading: A Guide to Private VPN Services

Many readers are understandably concerned about recent moves by the U.S. Congress that would roll back privacy rules barring broadband Internet service providers (ISPs) from sharing or selling customer browsing history, among other personal data. Some are concerned enough by this development that they’re looking at obfuscating all of their online browsing by paying for a subscription to a virtual private networking (VPN) service. This piece is intended to serve as a guidepost for those contemplating such a move. —Krebs on Security

Worth Reading: Is Enterprise Networking Lost in the Cloud?

In the end, only a combination of private, public and hybrid networking can deliver the levels of reliability, security, scalability and flexibility that today’s enterprises require. Traditional private WANs are simply too slow, inflexible and expensive for the multitude of cloud-based applications. Typically, the data center becomes the central gateway for security, Internet breakout and data exchange. —Data Center Journal
