Federated Systems & Network Protocols Are Unfixable
Federation means that nothing can change in networking. Right ?

H3C/Tsinghua Completes
A new IT behemoth has bellied its way up onto the beach. IDC has issued a press release: One year after the announcement of the subsidiary of Tsinghua Holdings, Unisplendour Corporation Limited’s plans to acquire 51% share of H3C Technologies and Hewlett Packard Enterprise’s China-based server, storage and technology services business, the company finally completed […]

Open Source in The Enterprise Panel
Open Source TL:DR – I hosted a keynote panel during Interop Las Vegas 2016 on the topic of Open Source in the Enterprise. Here are the panel notes I prepared. Network Computing wrote up the article here: Open Source: The Enterprise Impact | Network Computing. Premise: In 2016, we are talking about new problems with Open Source […]

Gartner Being Wrong on OpenStack
This week saw established analyst firm scrambling to recover after realising that OpenStack is a huge, unstoppable thing. Sean Kerner writes that 451 Research released some data : 451 Group now reports 2015 OpenStack ecosystem revenue at $1.2 billion and forecasts it will grow to $3.37 billion by 2018. From 2014 to 2018, 451 Group has […]

Blessay: IPv6 was Designed For Different Er
IPv6 is badly designed. Constant updates make us uncertain. Lack of features make us unwilling.

Analytics of Everything
The ashes of network monitoring products from the last 30 years is a Sauron-sized mountain of tears on which we must build the a new generation of tools. Analytics, machine learning, big data and user interfaces are the new hope. Network as a Service A key feature in “as a Service” products is transparency & […]

Blessay: Your Future WAN is a 5G Network
But I've been reading whitepapers about the possible future of 5G networking and its becoming clear to me that the larger part of any private WAN (if you have one at all) is going to be wireless in the next ten years.

There is NO IPv6 Standard
Geoff Huston highlights that the IETF has never completed their standard process. One hundred and forty-six of these RFCs are Informational, four of these are Historic, 23 are Experimental, five are Best Current Practice and the remaining 193 are Standards Track documents. Of these 193 documents, 24 are already obsoleted, 164 are Proposed Standards, just five […]

SDN is NOT an Innovation, its Iteration
The big Red Herring in networking over the past ten years is most things labeled “innovative” when the word that should be used is “iterative.”

Response: Stack Overflow: The Hardware
StackOverflow doesn’t run on the public cloud, its runs on dedicated hardware beacuse performance matters. Baremetal is fast. because their human infrastructure knows what they are doing the installation uses physical routers and firewalls. 2 Ethernet switches – Nexus 5596UP ( I don’t count Nexus 2000 as they are not switches, they are hubs running 802.1BR) I’ve […]

Response:What should IETF “standard track” actually mean?
Russ White blogs on “What should IETF “standard track” actually mean?”. I’m critical of two things: lack of focus on Enterprise networking that standards being produced have little relevance to real world uses. The second is likely to be people problem because organisations inherently build up resistance to new ideas and become self-referential. The first […]

Enterprise Sticking With Private Cloud
This slide was posted on Twitter this morning rom Sam Charrington: This matches with what I hear and see in the market. Most enterprises will build private clouds They have so much data in their existing DCs that migrating is impossible/impractical That OpenStack (not VMware SDDC) is the preferred platform Some key market points that I […]

Network Monitoring, Moral Hazards and Crumple Zones
Software Defined Networking & self-driving cars are closely related because they are automated systems. When automated systems go wrong who takes responsibility ?

IETF and an “Acid” Testing Suite
Since I roundly dumped all over the IETF I’ve been thinking how the IETF could improve. My current best idea is “testing”.

Research:The Evolution of Layered Protocol Stacks Leads to an Hourglass-Shaped Architecture
One reason why IPv6 has slow adoption is that the seven layer model has created a “waist” where change is possible in some layers but impossible in others. As the diagram below suggests, change in applications and protocols (Layer 5/6/7) is possible while Layer 1/2 has slower change but it does happen. The one thing that […]

Repsonse: Design in Tech Report 2016
I have been talking about the value of well designed interfaces in network monitoring tools for a few years because the current generation is badly designed. I'm wasting a lot of time getting through the pain barrier before the software becomes useful.
