Posted by Padre @ 12:02am See Packet. See Packet Sit. cPacket Run!For most system administrators, network monitoring is like car insurance: we know we should have it — we know we’ll regret doing without it — we know that it can provide all sorts of interesting and useful purposes — and yet somehow the muss and fuss involved in getting it right and understanding its utility is overcome by the desire to “get in and go.” The usefulness of network monitoring tools is eclipsed only by the difficulty in getting many of those tools running, or in the learning curve to decipher the information coming off those same tools. cPacket Networks hopes to change all that with their cVu 1000 Distributed Appliance for active network traffic inspection and response. ![]() The cVu1000 on Paper
Backstory of their cVu 1000 Distributed Appliances. It was my responsibility to find those units appropriate homes where they could tap and monitor the traffic running through the more interesting parts of our network. After a quick tutorial on how the devices worked, we agreed to use the cVu 1000s to monitor four particular segments of the eNet: show floor, classrooms, registration and press. Installation was straighforward — we use Systimax QDs to connect fiber umbilicals from the core switches to the show floor racks. The cVu 1000 came populated with GigE copper modules, but since they use standard SFP ports, we were able to swap the GigE copper modules for fiber units. Placing the units inline was a simple matter of plugging the fiber that originally went from the QD to the switch into the “A” port of the cVu and running the “B” passthrough back to the switch. Installation didn’t necessitate any changes in our network topology and we immediately began seeing trafic statistics on the built-in LCD screen on the front of the unit. I like the cVu 1000s — they’re small, easy to install, feature-packed on paper, and cPacket’s engineers are hard-working, honest uberGeeks. They claim that their custom-developed ASIC allows for deep inspection of every packet at linespeed without adding latency to the network. Still, with monitoring vendors like Fluke, Network Physics, Network General, Gigamon, Groundworks, and others already on the Interop train, I didn’t know what to expect from cPackets and their little black box. Trial-by-Fire that made it easy to isolate, diagnose and correct network problems? Did cPacket Networks come up with a formula for shifting monitoring from a “what happened” to a “what’s going to happen” paradigm? After seeing the cVu 1000 go through a trial-by-fire of being in the enterprise-class network that we call the Interop eNet, my answer would have to be a loud and resounding, YES. The cVu 1000 is the first standalone, in-rack monitoring tool that I have been able to master in under 30 minutes. Their interface is extremely intuitive — reporting is divided into “live” and “historical” groups which give users immediate access to the statistics that matter, like bandwidth consumption and DNS requests/replies. Data can be represented in a variety of user-configurable graphs and charts. Users can easily switch between the various cVu 1000s installed in the network and drill-down their views from hours to seconds in order to locate spikes, drops or attacks.
These screens give a good representation of the information that the cVu 1000 makes availible in real-time. It is important to note that the interface was very responsive: Over the course of the show I never experienced a freeze, hickup or drop in my live or historical views through the cVu 1000 status screen. Show Impressions passing through the network, the bandwidth counters are surprisingly informative even with such limited real-estate. The day that the full network was up and running, the cPackets guys introduced me to the status screen and gave me a quick (10 minute) tutorial. From that point on the cVu 1000 became my first stop whenever NetServ (Network Services Help Desk) received a complaint about connectivity or speed. I was amazed at how quickly I was able to learn the interface and at how useful the cVu 1000 was in diagnosing problems — within 4 hours of collecting data we were able to isolate several ARP storms from the registration area, DA attacks over the classroom wireless, DNS problems in the Press area and bandwidth hogs on the show floor. Conclusions amazingly versatile piece of monitoring gear that is easy to install, easy to use and designed with scalability in mind. I can’t wait to use it in the eNet for Interop Las Vegas, and this time I plan to try the mirroring and filtering functions of the unit. |

Posted by Padre @ 5:58pm Layer 0 SecurityNow that the show is over and the crates have been packed, there’s time for the team to catch our collective breath. While We need PHYSICAL security. We may have some of the best security engineers in the industry, driving advanced security solutions from Juniper and During the show we had two incidents without our Network Operations Centers. In NOC 2 we had an unknown individual rummage We were relatively lucky this time: a digital camera can be replaced and the intruders didn’t compromise the network. Thankfully, we have Axis Communications as a Solutions Axis was once again in the NOC with their advanced network video products.

Posted by Padre @ 8:32pm Lone WolfAs one of the newer Team Leads and younger volunteers, I spend a lot of my time playing with the “bling-bling” technology that comes to the show. Axis Communications’ network cameras, Anthology Systems’ Yellow Machines, SlingMedia’s SlingBoxes have all taken up a large part of my Interop work docket because they are splashy, fun technologies that cross the boundaries between enterprise networking and consumer products. I like that part of my job because I get to show the world how our Interop partners are NOT just about corporate networks, data centers and lights-out-management. Even so, you can’t sit in the HotStage warehouse for as long as I have without getting at least a little interested in some of the products that don’t reguarly make the front page of “PC Magazine” or the screen of any number of tech-enthusiast programming. One of the priveledges of my job is that I get to see the technology behind the technology — The hidden switches, boxes and rackmounted units that make the “bling-bling” technologies possible. Today I want to share one of those pieces of tech with you…
At our show in New York, Coyote Point will be providing load-balanced DNS and DHCP while also acting as the front-end for many of our Axis network cameras. For the conference attendee, or to the Internet user logging into our content from outside the show, Coyote Point is the vendor that will be ensuring that their DNS queries go answered, their video and audio streams stay up, and their Interop web surfing experience stays fluid. — All without so much as a packet flutter to show that the 450si is there. One thing is for sure, I will be pushing their gear in a big way. Keep watching the blog to see a full-blown review of the Equalizer’s load balancing, acceleration and failover capabilities. |

Posted by Padre @ 9:03pm It Came From SPACE!The Interop crew is well into the limbo period between the end of HotStage and the start of the show. A few of us have worked hard over the last two weeks to tear down, pack and roll all the equipment in preparation for trucking it across the country. The warehouse floor is bare, the boxes have been stacked and we hope that we have thought of all the probable contingencies and brought the appropriate equipment to deal with them. Still… just because we’re between caffeine binges, it doesn’t mean that we don’t get to play with more interesting technologies. Try THAT with your local Starbucks WiFi connection. Xirrus was a last-minute addition to the network as our lead engineer, Glenn Evans, searched for a wireless vendor (preferably an upstart with exciting new technology) who could provide a solution that would stand the ultimate test of conference WiFi. You see… WiFi at Interop is not a challenge just because of the large number of attendees with laptops, or the insane amount of noise generated by the HUNDREDS of vendor radios turned on when the exhibits open, or even because of the inherent weaknesses of WiFi in the 2.4Ghz range. Rather, it is the PERFECT WiFi Storm of these three factors that threatens to tip over access points, blot out the usable WiFi spectrum and make wireless communication akin to lighting a candle in a hurricane. The solutions we’ve used the last three years from our vendor-sponsors Aruba and
href=”http://www.extremenetworks.com/solutions/applications/wireless.asp”>Extreme Networks WiFi storm with flying colors. However, being the geeks that we are, we didn’t want to just keep looking at the same solutions that we KNOW will work. Furthermore, we very much wanted to see if there was a technology in the wild that perhaps could provide better unreal-world performance for the show floor, classrooms and around the hall.
![]() In theory, just a few of these units should more than cover every space in the Javits. Now all we have to do is configure it, deploy it, open the hall, and watch how it fares in the perfect storm…. Surfs Up! |

Posted by Padre @ 7:39pm The Purple Roach MotelIt’s inevitable… it happens EVERY show. The moment we advertise our class A set of IP addresses to the world we are instantly hit with every sort of network garbage, virus, trojan, worm and exploit that exists in the wild. It’s like clockwork — We move to our new location, power up the gear, test our network in relative calm — then advertise the routes and watch the crap-traffic go through the roof. It’s an annoyance that threatens, at best – to consume much of our bandwidth and make externals unstable, at worst – to make our network unusable.
He’s smiling because he’s Mike Skripek, the technology evangelist for Extreme Networks’ security solutions. It’s his job (should I say pleasure?) to tout the virtues of Extreme’s Sentriant line of products and demonstrate how they can protect just about any network, from just about any threat, in just about any environment. Just yesterday Mike was kind enough to give me a demonstration of an forthcoming Extreme product that is designed to make network administration easier by demanding an admin-adjustable level of security from network clients before they are allowed onto the network. He demonstrated the close integration of Extreme’s complete line of Sentriant software and hardware….. I promised not to let out all the details of how the Sentriant’s do their magic (after all, Extreme deserves to tell it themselves) but I can tell you that these boxes were a hit in Las Vegas. Part of the fun of sitting in NOC 2 was watching Mike’s status screens as they counted up the number of hackers and malicious coders that were being snared by any number of the Sentriant’s countermeasures, honeypots and delaying tactics. In short, I know that I’m a geek because this type of technology excites me, but at least I’m a secure geek! |

Posted by Padre @ 11:50pm NAV: “Network Attached Voyeur”I can’t help myself. I know that I’m an engineer dedicated to the highest standards of professionalism and ethics — I know that I am part of a generation that needs to prove it’s trustworthiness at every step of the way — I know that I’m a man of the cloth — Yet still, I find myself irresistably pulled towards the allure of network voyeurism. It wasn’t enough that the Gigamon could tap every single packet that flowed through out fiber and copper connections. It wasn’t enough that the Fluke gear can give real-time analysis network health. It wasn’t even enough that the Consentry boxes could count, seperate and collate packets in any shape I desired — no… I needed more… I needed Axis!
Once again Axis Communications has joined Interop as a Solutions Provider. They made a splash at the Interop Las Vegas conference in May and now they’re back, providing solutions that can fill the needs of even the purist videographer and the prima donna network administrator. In addition to the 207w wireless network cameras (the smallest network cameras in the world), the 211 midrage unit, and the the 221 all-weather/all-lighting conditions box, Axis has now sent us the Axis 230 camera so that we can stream and capture the keynote addresses. Not only is the 230 an incredibly high-quality unit (glass optics, analog video output, network controlled 18x zoom, built-in and external audio inputs, IO ports, POE) but it also provides multicast support so that we can sent out our keyotes to the entire showfloor in addition to our Internet users.

Posted by Padre @ 11:52pm The BoneyardI was sitting at my desk in the warehouse, playing with the new OpenSource Trouble Resolution System (OTRS) that we’ve installed to handle our trouble tickets, when I looked around at the racks full of millions of dollars worth of gear that took hundreds of hour of engineering time to install and configure. We’ve truly put blood, sweat and tears into creating the best network that we possibly can in as the short time frame that we are allowed.
I suppose it’s all part of the job. — In fact it’s part of the allure of being part of the Interop team: that I’ll come back for the next Hot Stage and find a brand new set of gear, software and challenges that will challenge me, push me and make me ask questions of my fellow engineers. — Still, there is a little bit of wonder every time I’ve helped to clear the PEDs after a show and rip apart (gently) the copper, fiber, steel and silicon guts that make up our network. |

Posted by Padre @ 4:47pm Warehouse Madness!I spent much of the day fiddling with VideoLan so that I could transcode the MPEG-2 stream coming out of the Axis 230. With the help of Daniel Chen, an Interop Team Members who work with EMC, I was able to get the multicast stream out of the 230 and onto the network. I used the VideoLan client to receive the stream and rebroadcast it as a WMV stream which was then picked up by a Windows Media server for serving across four publishing points and the Coyote Point load balancer. Everything was moving smoothly until the transcoding process lost audio. Now I can get audio or video, but not both.
I know that this is probably an easy fix for somebody who does this on a regular, but unfortunately the warehouse is pretty empty today and I don’t have the luxury of the iLabs expertise or even Glenn Evans, “shut up and fix it” attitude. Still, it’s been fun to play. In addition to my multicast woes, Fry’s Fever has hit our warehouse crew hard. The weekend already drained most of the manpower out of our crew and when the people who showed up realized how small our group of weekend uberGeeks was going to be they set out on a trip (is pilgrimage too strong a word?) to Fry’s in Sunnyvale. They left about three hours ago… I’m not sure if I’ll ever see them again! Other than that, things continue to go smoothly at Hot Stage. The network is up and running, all peds are connected and the Extreme/Juniper team is creating all the rules needed for proper security and access. We’re at that point in Hot Stage where the engineers are starting to work on pet projects and “cool possibles” for future shows. I’ve got the Anthology Boxes once again and I’m trying to do something completely idiotic for the display. Tomorrow I want all the network cameras to be up and running so that I can get the Coyote point guys to start balancing the streams. All in all… it’s fun from here! |

Posted by Padre @ 11:59pm A Funny Thing HappenedSo a funny thing happened on my way to Interop — but to tell you that story, I first have to tell you this one… I’ve been tinkering with a little video project for the past week or so that I hope to get up and running today — I received an Axis 230 network camera from Steve Lewis over at Axis communications to use as the primary audio/video streaming device at our Keynote addresses. The unit itself is very well-equipped: aside from Axis’ typical stellar video quality, this camera also includes an 18x remotely-controlled optical zoom, external audio input, power-over-ethernet and the option for an analog video feed straight from the camera. Even if we were not to used audio piped in from the Keynote techs, I’m sure that this unit will give us great results.
The one problem with the 230 is that it is limited to 10 streams at a time. This isn’t because of any constraint imposed by the hardware, but because the stream output is in MPEG-2 format and Axis could only license 10 simultaneous streams. Since we hope to have significantly more than 10 simultaneous viewers of the broadcasts, we need a new solution. My idea is to use the multicast feature on the camera to throw out a MPEG-2 stream onto one of the Extreme switches. I’ll then use a Windows 2003 server to monitor the multicast stream and transcode the audio/video into WMV format on-the-fly. I’ll then use both that server and another box to distribute the streams through the Coyote Point load balancer. – Simple… effective… fast. — The only problem is that I have absolutely no experience with real-time transcoding. So we return to the “funny thing” on the way to Interop. As I searched around the web for clues as how best to accomplish the transcoding and restreaming, I ran into
href=”http://www.findarticles.com/p/articles/mi_qa3649/is_200109/ai_n8973063″>this Atlanta. I find it fascinating that here I am at Hot Stage, working with the most cutting-edge technology in network cameras, surrounded by some of the best and brightest engineers in the business, and I find out that Interop 2001 presented a perfect solution for an Interop 2006 problem — Now that’s just Zen Networking! |

Posted by Padre @ 10:17pm Bring It!Is it that time already? The Interop crew has officially kicked off Interop New York 2006 with the opening of the Hot Stage warehouse in Belmont, CA.
It seems like only yesterday that we were breaking down the last of the Interop show in Las Vegas and now we’re at it again, engineers and uberGeeks who get a sense of excitement and adventure out of tasks that most “normal” people would look at as work. — Then again, if we were normal people, we wouldn’t be worthy of Interop! Even before we rolled up the doors to receive the gear from our vendor supporters, several of us were hard at work ensuring that the Hot Stage will be a smooth process of installing equipment, verifying interoperability and documenting every last cable and fiber. Dennis Smith, Glenn Evans and I spent the better part of two days prepping the warehouse for its transformation while also installing the fiber and copper backbone for the network. With the ease with which we installed the Systemax fiber bundles (which we now call “green” for the lack of a better name) we were soon in the unfamiliar position of having the ENTIRE backbone installed and verified before the first piece of vendor gear made its way into the racks. |
