'The Best Protocol Evar!!11!'
BIC-TCP: The next big thing since 2003
by Karl Bode 05:31PM Thursday Apr 15 2004
BIC-TCP (binary increase congestion transmission control protocol), a protocol designed by researchers at North Carolina State University, seems to get media attention roughly once a month whether or not the project advances. This week it's Newsfactor that takes a peek at the next generation protocol, perpetuating some incorrect assumptions. BIC-TCP "makes today's high-speed digital subscriber line (DSL) connections seem lethargic," the researchers claim.

Studies found BIC-TCP topped the charts repeatedly in terms of stability, scalability and fairness when compared to other protocols, seemingly making it the perfect eventual replacement for TCP/IP. We kept wondering why each article kept comparing the speed of a protocol to a hardware transmission medium; this latest report again stating BIC-TCP offered speeds "6,000 times that of DSL;" even the article's headline claims the protocol could "Leave DSL in the dust."

The researcher has since clarified his comments, saying his original quote was twisted by the press release staff and has been bouncing around the news wires confusing journalists and readers ever since. He says his quote was that the protocol "can run in 10Gbps networks and use its full capacity." Media outlets also continue insisting it's a "new" protocol, despite the fact the project has been under development for years.

This pdf outlines the tests done at SLAC (Stanford Linear Accelerator Center) last year comparing BIC-TCP to other next generation protocols (also see the website).

I am all for this! And is this over existing landlines and cable? or over fiber?

Re: Where do I sign up?

its a protocol not a medium. that is the whole deal.. its marketing fluff from people who you wouldn't expect it from.

Re: Where do I sign up?

so i could use a 56k dialup modem with this "protocol" and get better than FTTH speeds?

i doubt it.

No. You could use this protocol on a 56k modem and get 56k speeds.

If it wasn't for the FCC cutting that 56K to 53K...

from what I got out of it, it would replace tcp/ip all together, ie. the syn ack mechanics.... sounds like it would be more practical for back-end providers.. They are trumping this up but I must ask where is IPv6 at?

It's not a new compression format or anything like that; it's a TCP that's able to handle such high speed transmission - standard TCPIP isn't really made for communication at that level. You still need the infrastructure capable of handling that bandwidth.

i thought UDP addressed a lot of these issues already, no?

Re: Where do I sign up?

UDP is a broadcast protocol. It doesn't care if the other end got all the packets or not, it just throws them at you. TCP needs to know that the other end has received all the packets it's sent before it'll send more.

No, UDP is for cases where you don't care whether your data gets there or not.

(Not actually true, but a close enough characterization for this topic).

ok, so how does this new protocol work? how is it soooo much better than current tcpip?

who cares?

lines are in bps/kbps/mbis

not tcp/s

so they made a protocol that can sucessfully flood a 10gb connection... awesome!

i dont care!

my dsl is still 1500kbps... no matter what protocol it will continue to be 1500kbps

Re: who cares?

Yes, but with this protocol when you access a site to download a file it'll actually download faster than 150-200kb/s. And your speed test will not be 1200-1300kb/s.

Re: who cares?

i doubt it... at best if it has less overhead i may see what? 50kbps more? i get like 1420kbps down in tests, and my line is provisioned @ 1470kbps...

No, it would help you in that it would eliminate some of the overhead and let you get closer to what your ISP tells you your paying for;)

Care to explain what 'overhead' it 'eliminates' ?

Re: Internet?

My ISP (roadrunner) gives me 3077kbps max download speed which takes care of the overhead so I actually see a true 3mbps download rate. I get what's advertised. On dialup, this would only increase speeds by maybe 1-2kbps. I guess every bit counts, but the time needed to change over the whole internet to this new protocol is definitely not worth the tiny increase people would see.

Nice but unrefined

the PDF file had some pretty interesting things to say but in the end what we're probably looking for is a protocol that can adjust to the circumstances dynamically, if that is at all possible. all the ones listed have their strengths and weaknesses but why settle for a compromise if we can implement all of them in one dynamically-changing protocol

Re: Old news!!!

It's NOT old news. It's the correction of old news. These outlets keep repeating these quotes that makes no sense....This NewsFactor story is the fifty-seventh time I've seen someone compare a protocol to hardware without anyone saying anything....Read the title of the Newsfactor story.

And Rhee's clarification in his FAQ is new:

Re: Old news!!!

Either they are trying to reach out to nontechnical people who do not know what a protocol is, or they're just plain dumb themselves... most people don't even know what an IP address is.

@dsl.chcgil.ameritech

I'd like to

I'd like to use this on my home network but I'd doubt it would do a thing (perhaps for my wireless connection eh) anyway to all those who are saying that it will give YOU a bots of around 70kbps, just think about the fact that YOU aren't the only one on that network and certainly not on the interent. I'm not attacking anyone I'm just saying that YOU are only ONE of THOUSANDS and reducing overhead and greasing the lines, so to speak, to each of these thousands is a good thing!

With all that being said I haven't read this stuff and I don't know if they are on to something but I do know it about dang time.

Look outside the box!!

Yeah, it may not help the actual connection between you and the internet, but if it reduces overhead by so much, then it will OVERALL improve the internet as a whole. That means that the connection between you in Florida and that server you are downloading from in Washington state will be much better. It will mean that more information can flow over the same pipeline. And it will help open the door for more bandwidth to the home. It isn't all about your extra few Kbps. Personally less overhead for me could equal out to my VOIP bandwidth down.

Re: Look outside the box!!

IMHO - this isn't going to be for the home user. TCP/IP is good right now for the home user. They don't see that much drop off with the overhead. This new protocol is for where the rubber meets the road - at the backbones.

This would mean faster data transfer between the OC connections and could use their true data bandwidth. This also means that they could use smaller machines and get the same data transfer rate.

Look at it this way. Right now we need to put hundreds of corvettes to push data. But if we use this new protocol - all we would need is hundreds of Honda's - that would run at the same speed.

At least that's how I understand it

Anyone who understands how TCP/IP, or other protocol suites work, should easily understand how less overhead can increase transfer speeds. But, for those who don't understand, I'll try to simplify it as much as I can.

Let's say two people, user A and user B, have 2MBps DSL lines. Here is an example of how user B can download a 100MB file faster than user A, even though both users have 2MBps lines.

1. User A downloads the 100MB file using a network protocol that has 50% overhead. This means that while user A's line has a throughput of 2MBps, user A is only downloading the file at 1Mbps. The other 1Mbps of bandwidth is wasted on protocol overhead. At 1MBps, user A downloads the 100MB file in 100 seconds.

2. User B downloads the 100MB file using a network protocol that has 25% overhead. This means that user B is downloading the file at 1.5MBps. 0.5MBps of bandwidth is wasted on protocol overhead. At 1.5MBps, user B downloads the 100MB file in 66.7 seconds.

If you were able to understand my example above, you can see how decreasing network overhead can speed up data transfers without increasing the bandwidth.

Note: B4 anyone flames me, remember, this is a very simplified explanation. I know the network protocols don't account for 100% of overhead, and yes, I purposely stated line speeds in MBps, not Mbps, for the sake of simplifying the math. I know 2MBps would actually be a 16Mbps line.(Not possible with current DSL technology)

Re: Look outside the box!!

Shame... After that last post with the note at the bottom, I noticed that I used Mbps twice in the first example. Forgive me.
