Lawful Interception or LI is short is a key tool for any government to maintain public order and security.
In the past I wrote a lot about LI (even stared in a movie and mentioned by Wikileaks article) but times are chaniging so there's a need to provide an update.....
LI is obtaining communications network data pursuant to lawful authority for the purpose of analysis or evidence. I do not want to get into a discussion about the unlawful use of data obtained by LI systems or privacy related...

This is Part 2 of 2 of my recent Blog Post regarding Interop Las Vegas 2012, where Net Optics was invited to deploy our Application-Aware Network Performance Monitoring appliance, Spyke, into the Interop NOC. We found that via Spyke collecting the data and making it meaningful we were able to identify the user behavior on this unique network, and create the kind of story that helps businesses both better supervise the behavior of their employees, and apportion the correct resources into the relevant areas of network need. Read Part 1 of 7 Million Network Connections from Interop - What Network Performance Monitoring Reveals About Attendees. ...

Being given the opportunity and honor to monitor the Interop Las Vegas network last May (2012) filled this software engineer with excitement. All that data, all those graphs that were generated… oh my! In this 2-part post I'll be reviewing what the network traffic can teach us about how attendees utilized the network. We'll be at it again at this year's Interop Las Vegas 2013, at Booth #1559.
How Well Behaved Are Users of the World's Largest Temporary Network?
Net Optics was invited to deploy our highly robust Application-Aware Network Performance Monitoring appliance, Spyke, into the Interop...

Next month my team and I will be presenting at multiple events around the world. During the preparation and creation of new content I was looking for some fun facts about the Ethernet protocol which will be celebrating 40 years soon(almost as old as myself, much more popular and useful :-)
According to Wiki, Ethernet was developed at Xerox PARC between 1973 and 1974.It was inspired by ALOHAnet, which Robert Metcalfe had studied as part of his PhD dissertation. The idea was first documented in a memo that Metcalfe wrote on May 22...

Ethernet Summit - A look into the future of networking
Last week I was a speaker at the Ethernet Summit. This convention packs a lot of people who set the path for the network industry. In the same track I delivered a presentation, they were talking about 400Gb network, delivering 100Gb on twisted pairs and ways of testing these high speed network technologies. All the presentations were highly technical and gave a glimpse into the future of high-speed networking and what we can expect a few years down the road.
One thing that was apparent from walking around and listening to all these people delivering their vision of the future of technology, was that the need for a monitoring infrastructure like the...

Director and Director Pro version 7.5 is now available!
This release includes many enhancements and several fixes to issues discovered in the field.
Some of this release highlights:
- Enhanced counters and additional statistics screens: New counters for different frame sizes on Rx and Tx, collisions, CRC errors, oversize packets, etc.
- Copy_drop filter command: A new a filter option to be used with copy commands. With this option one can drop data when it meets a specified condition, even if there are filters with higher priority. (This will be a very popular feature for cyber-security implementations).
- Filter GUI enhancements creating simplified options to create User Defined filters
- ...

Since I wrote about SDN late last year and our announcement and demonstration at the RSA conference In February 2013, interest about SDN has increased. Yet, is not always clear what all the hype is about and what will inevitably be the role of networks as we know them today.
Different protocols and technical terms are being used to describe a function and a use case...

Many times I found myself trying to figure out how to convert decimal to hexadecimal values in order to decode packet captures or create User Defined Filters (UDF) for special use cases. A very simple to use UI-based tool of xStream products (Director xStream, xBalancer, iLinkAgg xStream) provides such functionality exactly.
Enjoy !

Overview
Net Optics iBypass is a bypass switch available for in-line network security appliances, such as intrusion prevention systems (IPS), Web application optimization devices, and firewalls. The Heartbeat feature allows the iBypass and the IPS to share state information, protecting against link, application, and power failures on an attached IPS device. A configurable heartbeat packet sent from the iBypass Switch to the IPS helps identify link anomalies or device failures. In the event of a device failure or a software malfunction, traffic is routed from the inline appliance through the iBypass Switch.
This note explains how the configurable Heartbeat packet feature works and how to configure it.
