Fresh Thinking on Programmable Storage

The difficult part about storage these days is far less about capability than about adapting to change. Accordingly, the concept of programmable storage is getting more traction.

With such an approach, the internal services and abstractions of the storage stack can be considered as building blocks for higher level services and while this may not be simple to implement, it can work to eliminate duplication of complex, unreliable software that is commonly used as a workaround for storage system deficiencies.

A team from the University of California Santa Cruz has developed a programmable storage platform to counter these issues called …

Worth Reading: Is cloud moving too fast for security?

That’s at least five-major cloud application and infrastructure data breach incidents for 2017, and we’re only in July. Add in the number of ransomeware and other attacks during the first half of this year and it’s clear the cloud has a real security problem. By now, most everyone recognizes the benefits of the cloud; bringing new applications and infrastructure online quickly and scaling it to meet ever changing business demands. —Doug Lane @ Cloud Security Alliance

Change in the Work Place: Attitude Can Be Everything

Change in the work place can be hard, unsettling, uncomfortable and… oh screw it… let’s just say it…. Change in the work place can just be down right scary when we are in the midst of it. 

I’m 52 so I’ve been through a lot of changes in my work environment over the years.  Since I’m a control freak it likely isn’t much of a shock that work changes like taking on a new job in a new company or new department aren’t the ones that I have the hardest time with.  I can see that this is because I feel like I’m the one who initiated the change in those situations.  I made the decision to move to that new company, job, or department.  I interviewed for it.  I felt it “called to me”.

But change in the work place is change in the work place.  Whether it is me initiating the change… or the change being “done to me”.  So why does a large re-organization in the same company feel scarier to me than me going to a new job at a new company?  They are both change.  Continue reading

IP Infusion powering the world from behind the scenes

Founded by Kunihiro Ishiguro and Yoshinari Yoshikawa the founders of GNU Zebra, came together to form IP Infusion back in 1999 as a commercial-grade, hardware-independent networking software company. If you’re not familiar with Zebra, you probably know it’s little brother Quagga which powers everything from Cumulus Linux to Vyatta and even my old digs.. Imagestream routers. Ishiguro and Yoshikawa took Zebra, and built ZebOS, which has been working behind the scenes in products we all use every day for years. IP Infusion’s ZebOS powers everything from F5 LTM’s and Citrix Netscaler’s to Plexxi, SK Telecom, and Huawei networking products.

Today IP Infusion is selling two variants of ZebOS to OEMs, OcNOS and VirNOS. OcNOS is a full featured network OS built specifically for White Box OEMs looking for switching, routing, MPLS, and SDN support. It can support a hybrid, centralized, or distributed network framework which provides a scalable, modular, and robust framework that can be deployed on merchant silicon. VirNOS is their NFV solution that can be used for distributed or cloud based vCPE, vPE, or vRouters in your data center.

Whitebox networking is a really exciting market that I have been looking into since the SDN craze started. Continue reading

JUNIPER NORTHSTAR 3.0 – SIGNAL TRAFFIC ENGINEERED MPLS LSPs BETWEEN TE DOMAINS

In this post, I’m going to explain how we can use an SDN controller to provision traffic-engineered MPLS LSPs between PE nodes situated in different traffic-engineering domains.

The SDN controller that we’re going to use is NorthStar from Juniper Networks running version 3.0. For more information regarding NorthStar check here. There is also a great Day One book available: NorthStar Controller Up and Running.

Overview

Typically, in order to provision traffic-engineered MPLS LSPs between PE nodes, it is necessary for the PEs to be situated in a common TE domain. There are some exceptions to this such as inter-domain LSP or LSP stitching. However, these options are limited and do not support end-to-end traffic-engineering as the ingress PE does not have a complete traffic-engineering view. I personally haven’t seen many deployments utilising these features.

So, what’s the use case? Many service providers and network operators are using RSVP to signal traffic-engineered LSPs in order to control how traffic flows through their environments. There are many reasons for doing this, such as steering certain types of traffic via optimal paths or achieving better utilisation of network bandwidth. With many RSVP deployments, you will see RSVP used in the core of Continue reading

What is Layer 0 in the OSI Layers ?

What is Layer 0 in the OSI layers ? Isn’t OSI (Open Systems Interconnection) seven layers?    Yes it is. In the standard, seven layers have been defined. Just let’s remember the seven layers of OSI.   Layer 7: The application layer. Layer 6: The presentation layer. Layer 5: The session layer. Layer 4: The […]

IDG Contributor Network: AMP and ThreatGrid Integration into Meraki UTMs

Lately, I have been spending a lot of time on integrating security systems together, and specifically focusing a lot of my energy on Cisco’s Advanced Threat Security product family. (Disclosure: I am employed by Cisco.)Which is what brings me to Cisco’s Advanced Malware Protection (AMP), which is a solution to enable malware detection, blocking, continuous analysis and retrospective actions and alerting.In fact, when the Talos cyber-vigilantes parachute into an environment and performs their forensics analysis and active defense against attacks—AMP is one of the primary tools that they use.To read this article in full or to leave a comment, please click here

IDG Contributor Network: How immersive technologies will reshape networks

In the late 1990s and early 2000s when it became too difficult for large companies to manage their own WAN footprints, they adopted managed multiprotocol label switching (MPLS) services. These offered a simple connection at every location and offloaded the complexities of building large-scale routed networks from enterprises to the service provider.The advent of cloud computing, however, changed the dynamics of MPLS forever. Enterprises not only needed ubiquitous site-to-site connectivity, but also required better performance from the network to support Software as a Service-based business applications hosted in third-party data centers. In addition, video was becoming a standard mode of communication for corporate meeting and training applications, boosting the need for more bandwidth across the network.To read this article in full or to leave a comment, please click here

MITRE Data Center Retrofit Is a Model of Efficiency

Networking Through the Ages

The IoT needs simulation to grow

Without simulation, complex systems would fail. Satellites would not reach an accurate orbit, semiconductor circuits would not function, and bridges would not carry the load. Businesses and governments would not invest in these projects without robust simulation software. And without a simulation proving value and functionality, IoT networks of hundreds of thousands or millions of inexpensive devices adding up to large capital investments will not be built.Researchers from the University of Bologna published an analysis of IoT simulation and a smart cities vehicular transportation system case study (pdf). They recommend a networked simulation of orchestrated simulators that model specific IoT features that fit the diversity of IoT devices and use cases.To read this article in full or to leave a comment, please click here

RFC8200: IPv6 Is an Internet Standard

You wouldn’t believe it – after almost 22 years (yeah, it’s been that long since RFC 1883 was published), IPv6 became an Internet standard (RFC8200/STD86). No wonder some people claim IETF moves at glacial speed ;)

Speaking of IPv6, IETF and glacial speeds – there’s been a hilarious thread before Prague IETF meeting heatedly arguing whether the default WLAN SSID should be IPv6-only (+NAT64). Definitely worth reading (for the entertainment value) over a beer or two.
