Ask Slashdot: VPN Setup To Improve Latency Over Multiple Connections?

agizis Re:http://speedify.com/features/ (174 comments)

This is Alex from Connectify. Sorry to hear you weren't happy. We put out a new release *yesterday*, with huge improvements on how both loss and jitter are handled. Since you have both, I think this could fix your issues. Assuming that you are who your slashdot profile says you are, I just emailed you another license. Please give us another try, we're here to support you. New software here: http://speedify.com/blog/speed... Thank you for considering Speedify.

Ask Slashdot: VPN Setup To Improve Latency Over Multiple Connections?

agizis Re:mptcp (multipath tcp) is one solution (174 comments)

A MPTCP VPN would not work in the real world. When you tunnel TCP through it, you end out having to send ACKs for the ACKs. The end result is that the effects of even a tiny bit of packet loss is a performance meltdown: http://sites.inka.de/~W1011/de... To build Speedify, we needed to implement a new multipath protocol over UDP. But that let us do clever stuff with NACKing and retransmitting lost packets before TCP ever noticed, and we were actually able to reduce the effect of loss: http://speedify.com/blog/speed...

Ask Slashdot: VPN Setup To Improve Latency Over Multiple Connections?

agizis Re:Connectify.me (174 comments)

Hey, thanks for the mention. This Alex from Connectify. We've launched a new VPN service called Speedify that combines multiple network connections. It's very smart about jitter and retransmitting lost packets. I think it's exactly what the OP is looking for: http://speedify.com/blog/speed...

Ask Slashdot: VPN Setup To Improve Latency Over Multiple Connections?

agizis Re:Does nobody understand the question? (174 comments)

Hey, sorry for the hard sell, but this is exactly what Speedify does. It's a VPN that uses multiple connections. It also detects, and retransmits lost packets long before TCP notices. Latest beta has been tested on Amtrak trains combining their Wi-Fi with Verizon 4G. Please check it out: http://speedify.com/blog/speed...

Ask Slashdot: VPN Setup To Improve Latency Over Multiple Connections?

agizis Re:What makes you think (174 comments)

The servers can't handle getting the data from different IP addresses.. That's why you need a VPN-style server in the middle to put the packets back together in a sane way. This is what we do with Speedify: http://speedify.com/blog/speed...

Ask Slashdot: VPN Setup To Improve Latency Over Multiple Connections?

agizis Re:Actually, it's easy. (174 comments)

Ha, that's exactly what I thought when I started implementing it. But it turns out it's way harder than it appears. Differences between internet connection in latency, loss,bandwidth, jitter, and buffering all conspire to make this a very difficult, multiyear project. That said, we've done it already and put servers all over the world, so you can just sign up and use it. Speedify: http://speedify.com/blog/speed...

Ask Slashdot: VPN Setup To Improve Latency Over Multiple Connections?

agizis Re:Neat idea, but not worth the effort (174 comments)

This is what we do with Speedify: it's a VPN that uses all of your Internet connections at the same time. By the time we started dealing with issues like jitter and loss the level of effort exploded into years. That said you should check it out: http://speedify.com/

You're Paying Comcast's Electric Bill

agizis Re:Your math sucks and is biased! (3 comments)

Alex here, and, while that's a good observation, it's not that simple. As I described, this was the business setup. Comcast gave me two cable modems, one for my office and one for the Xfinity hotspot. The power I measure was solely for the hardware that was required to run the Xfinity hotspot. The question is, how different is the setup of consumers? They do share one modem, but in my experience most people are supplying their own wifi router (by linksys or similar) to give themselves a wifi network, in which case the fixed overhead of Comcast's wifi router is entirely there to supply the Xfinity Wifi.

Slashdot Killed My Kickstarter Campaign

agizis Re:Dude, you got a communication problem. (163 comments)

Thanks for asking, this was part of a campaign to sign up technically sophisticated beta testers for our new VPN product. I came to slashdot because of the concentration of such networking experts. The casual, ask me anything, tone was set specifically to disarm the frequent, negative posters who frequently post without contributing to the discussion in a meaningful way. At this moment, I have now signed up 249 people for the Switchboard beta (thank you everyone, we won't let you down). Thanks for your post.

Slashdot Killed My Kickstarter Campaign

agizis Re:Trust (or a lack thereof). (163 comments)

Interesting, thank you. In general I think the trust/privacy issues are bigger here on Slashdot than they are in the rest of the Internet (I submit Facebook's success as evidence). I think the subscription part was a bigger deal to more people. That said you clearly have a valid point, and your stories about those other products are clearly nightmarish. I'm going to keep this in mind going forward. And I get that nothing I say here will make you trust me. So are there standards/trusted 3rd parties, whose seal of approval would make you believe in our security/trustworthiness?

agizis Re:Further Questions (163 comments)

Thank you for asking. Yes, so in the new form, we're pushing it largely as a personal VPN. It's very easy to setup, and automatically does the same sort of firewall traversal (STUN, TURN, different ports, etc.) that Google Talk or Skype does to get through a firewall. So you can get a VPN server setup without having to deal with port forwarding on your router, or anything like that. We are smart about our channel bonding and protocols. As long as it's possible, we'll use UDP and get much better speeds than you would get with a TCP based solution. It does have the multiple Internet connection stuff going as well. Yes, for that to improve your performance, you have to set up your server somewhere with a very fast Internet connection. There are a lot of situations where this comes up: places where DSL is still common, and where you have a very mobile workforce, a lot of times people have access to both Wi-Fi and 4G or DSL and 4G.

agizis Re:Still don't quite get it (163 comments)

Thank you, good feedback. We're going after the personal VPN first, but I think that eventually we'll be able to return to the cloud server. There certainly were a fair number of people who really wanted it.

agizis Re:Linux Release (163 comments)

Linux will be a supported platform for Switchboard. We did a much better job of building cross platform C++ with an HTML user interface from the ground up. Dispatch's a code has a lot of Windows specific stuff throughout it, the port would have be a new development effort almost from scratch. So I can't really say if Dispatch will really ever happen on other platforms (it could but... not soon, anyways).

agizis Re:Stop feeding the trolls. (163 comments)

I felt like a lot people started off negative, but when I started actually answering, everyone seemed really well behaved. I was happy, I think that maybe more people from the stories should just jump into these conversations. In the end, I didn't have any bad "troll" experiences.

Ok, what the hell. My father is Evangelos Gizis. He's an academic, who among other things has done stints as the President of Manhattan Community College, President of Hunter College, and Provost of Queens College. He still wishes I had taken school seriously and gotten a PhD.

Slashdot Killed My Kickstarter Campaign

agizis Re:2 Questions for you (163 comments)

More and more, I'm coming to think of myself as a guy who takes complex networking technology and tries to make it simple. I'm doing this because I want to give people not only faster internet access, but also free them from the companies that would control what we can do on the Internet connections that we're paying for. Well that's my big vision, mostly I answer emails, and wish I had more time to actually code.

You're Paying Comcast's Electric Bill

agizis (676060) writes "We know Comcast is rolling out a new WiFi network that they're installing in customer’s homes, but most articles glossed over the routers' power usage. So using a Kill-A-Watt power meter, I actually measured and Comcast is saving tens of millions per year on the backs of their customers.

Comcast is turning your home into a public hotspot.

agizis agizis writes  |  about 6 months ago

agizis (676060) writes "Comcast has started using customers’ routers to create public wifi hotspots. They claim the "opt-out" hotspots don't leech from your paid bandwidth. But the bandwidth comes from somewhere. So, is it extra or is it what you paid for? The answer matters, because if they’re using your bandwidth, you should opt-out, but if it's extra, then you should start using it."

Scaling a Cloud Service Without EC2

agizis agizis writes  |  about a year ago

agizis (676060) writes "Last May, we began developing a worldwide cloud service where speed and reliability is everything. Like most startups, we started on Amazon Web Services (AWS). We fell in love with the functionality of EC2, but the honeymoon was over fast: the locations and pricing were just too restrictive. It's been a sometimes painful ride, so I wanted to share the story of how we broke the golden EC2 handcuffs and built our scalable service at a fraction of the EC2 price tag."

Taking a QUIC Test Drive

agizis agizis writes  |  about a year ago

agizis (676060) writes "Google presented their new QUIC (Quick UDP Internet Connections) protocol to the IETF yesterday as a future replacement for TCP. It was discussed here when it was originally announced, but now there’s real working code. How fast is it really? We wanted to know, so we dug in and benchmarked QUIC at different bandwidths, latencies and reliability levels (test code included, of course), and ran our results by the QUIC team."

agizis (676060) writes "Alex from Connectify here. I wanted to say thanks to all of you who commented on the Slashdot story about our Kickstarter campaign It was super-educational discussing Switchboard with all of you: you wanted your own servers, and we weren’t doing enough to communicate what was so special about Switchboard. Based in a large part on your feedback, we blew up our Kickstarter campaign, and changed almost everything. Thanks, Slashdot. This isn’t reddit, but ask me anything."

2 Years Since Landing on Slashdot

agizis agizis writes  |  more than 3 years ago

agizis writes "We want to take a moment during our birthday week to thank the Slashdot community. Slashdot was instrumental in helping us bring Connectify to tens-of-thousands of early-adopters who downloaded the first Connectify Beta, way back in 2009. The day we consider our oebirthday is October 27th, 2009. On that day, Connectify went from being an app that a few of us used on business trips, to a piece of software used by thousands of people around-the-world. A short post on Slashdot was the turning-point for Connectify, and the blogs and sites that quickly picked up on our application from there helped Connectify grow by leaps-and-bounds in a matter of days.

Thank you, Slashdot."
