Thanks!We received numerous product and solution awards recently. We also get a lot of recognition and media coverage. I would attribute those to the hard work, dedication and innovation of our team. The latest nominee (which is actually an award) belongs to our customers.Net Optics has been selected by the editors of Inc. magazine as one of America’s fastest-growing private companies in the publication’s 2010 hall of fame. Watch Net Optics CEO Bob Shaw on winning a spot on the 2010 Inc. 5000 Managing The Light Budget
There are different reasons for light loss that occur during transmission of light signals inside fiber or during the interconnection process of two fiber-based components:
The biggest loss often occurs due to insertion loss, which is the most important performance indicator of a fiber optic interconnection. Insertion loss is the loss of light signal during the insertion of a fiber optic connector. It is measured in decibels (dB). To maintain the minimum light budget loss, Net Optics Fiber Optics products (all different Tap and Tap modules) has different split ratio the amount of light that is re-directed from the network to the monitor ports) options. To calculate and better understand split ratio, the Net Optics Fiber Split Ratio Reference Chart is available. BTW, A good reference reading on light loss is provided by the Fiber Optic Association (see Guidelines On What Loss To Expect When Testing Fiber Optic Cables For Insertion Loss With A Meter and Source or OLTS). – Sharon Follow The Cable… If you were looking for another evidence of the dramatic shift in data center design and the migration to 10G, read the recently published “New Data Center Cabling Requirements” document that was released few days ago by Mark Fabbi(Gartner ID Number: G00205239).
This document, provides the physical cabling requirements for a growing (maybe I should write “big”) shift in network design.
In the past I spoke and wrote about the impact of 10G migration on the security pie market as it requires network and application security practitioners to look for new solutions that are capable to handle and/or secure and/or protect and/or monitor and/or inspect 10G (and beyond) traffic. The design of the physical cabling infrastructure is affected by the migration from the current dominating school of end-of-row network architecture to the future top-of-rack switching architecture. Due to the use of 10G networks and future migration to 40G/100G, new data centers will require much less copper.
Fabbi recommends enterprises using a top-of-rack architecture to use copper in the rack and OM3 or OM4 fiber to connect to the core data center network. In addition, new data centers should overprovision multimode fiber cable by a factor of 4x in anticipation of a migration to 40 Gigabit backbones. IMO, if you are involved with data center architecture and design, you should read this document.
ObservationsI’m visiting Haifa, Israel this week. A place considered by many as one of the coolest places in the Mediterranean. (“cool” as in “hot”. I wish that it was colder). This is a network and application security savvy country. Most of the customers that I am visiting are using more than a single tool to protect their applications. In some cases, there are more than two different tools to achieve higher level of security. The tool manufacturers vary, but there is one thing in common: Tools are very often (I would say more than 70% of the cases) are all installed in in-line mode, blocking policy violations. A violation can be an attack, or a diverge from the corporate governance policy that might lead to information leak and data loss. The corporations that I have visited are world leaders in their space. In other countries, there is more emphasis on business connectivity than in-line real-time, hard core blocking for security. In some cases, people refer to it as “monitoring” versus “preventing”. Net Optics Director and Director Pro are used by those customers as a tool to ensure connectivity even when the highest degree of security is required. It lets them balance between multiple tools, to make each one more effective and route different types of traffic via an in-line route while allowing other types of traffic to be routes through a monitoring only device. Yet it also provides the means to very quickly (in a matter of less than seconds) to switch policies if needed. One of the coolest use cases that customers are excited about is dynamic load balancing for inline applications using Director Pro. This unique solution allows to run multiple security device in in-line mode for blocking while avoiding asymmetric routing issues. University of Bradford Workshop: The Need to Monitor Speed
Tomorrow I’ll be presenting at a workshop hosted jointly by the University of Bradford and Net Optics partner, MarQuest Ltd., This is a one-day event that focuses on high-speed networking for security and performance. Workshops will cover such issues as minimizing analysis tool costs, performance-related security in high-speed networks, and developing an effective monitoring infrastructure. The event features Professor Demetres Kouvatsos Head of the Networks and Performance Engineering Research Group (NetPEn), Informatics Research Institute (IRI), University of Bradford. Chris Bloom, WildPackets Principal Software Engineer/ Developer Evangelist, Chris Devereux, Motorola Senior Technical Architect and myself. The topics covered will concentrate on the challenges of monitoring and analyzing data from networks which transport gigabit data streams. This will include the following areas:-
I have developed a new presentation trying to keep it “vendor free” while presenting my thoughts on developing the right infrastructure for effective monitoring. One of the thoughts that I will be presenting is related to the different tradeoff between the different functions derived by business decisions:
I’ll post the slides after tomorrow. Reminder: T1, T3A European friend is now performing is first implementation in the US and as such is starting to “discover” the differences between T1 and E1. Being such a nice person (what are friends for), here’s a short reminder: T1
T3

Thoughts The Enterprise LAN Magic Quadrant
In addition, Gartner made some interesting comments regarding the changes in the landscape as a result of economic conditions (changes in the buy patterns and habits of large organizations ) as well as the M&A activity (HP acquired 3Com and Avaya acquired all of Nortel’s enterprise networking business, including its LAN switching portfolio) or lack of (Brocade). If you are working for a large organization or plan to refresh your enterprise LAN or build a new data center, you should read this paper. New White Paper: Gaining Total Visibility for Lawful InterceptionThe term “lawful interception” (LI) describes the process by which law enforcement agencies conduct electronic surveillance of circuit and packet-mode communications as authorized by judicial or administrative order. Each country has its own criteria for defining criminal or terrorist activities; the purpose of LI is to gather evidence to detect and prevent such activities. In the United States, the Communications Assistance for Law Enforcement Act (CALEA) sets forth how service providers must support lawful interception. Abroad, the European Telecommunications Standards Institute (ETSI) drives adoption of standards for telecommunications, broadband, and related technologies in Europe and other countries.

I will let you read this document, which reflects a real phenomenon observed in the field, though in my opinion puts too much emphasis on FC consolidation. Based on a previous ESG survey (2010 IT Spending), top investments will focus on increased use of server virtualization, security, data center consolidation, upgrading networks, and protecting and managing data. One area of disagreement with this white paper content is around the focus of consolidation and where should a converged network be deployed first. The white paper suggests that initial deployments include blade centers and unified computing environments ad well as top of the rack switches (ToR) for new environments. While I agree that it makes sense (duh again…) I think that ToR deployments makes more sense to begin with. |
