packet compression to speed up link

Mon Aug 19, 2013 1:03 pm

Hi, I've been thinking is there a method to speed up your link using routerboards,

heavy packet compressing or heavy something

limitations... a leased line and a fixed budget
goal: something 10 times faster

Inspiration link:
Increasing wireless network speed by 1000%, by replacing packets with algebra

Just imaging if mikrotik can pull something like this off..

it wont be ten times faster but you can look at '/ip packing'

hmm I've been looking at that feature now for a long time, but not sure if it will work inside a sstp VPN tunnel with EoIP on both ends, to pipe thru a 10meg internet connection using a 1meg VPN link, and hopefully get more then 1meg bandwidth by using IP packing or am I completely mad?

You won't come anywhere near a 10x compression ratio. I reckon you'd rather see really some low 1.x factor in real world scenarios. Also keep in mind that a VPN's encryption adds a bit of overhead.

What your article points out is a way of getting rid of packet loss in wireless networks / speeding up retransmission and thereby getting closer to the maximum packet rate possible. It also points out at the beginning, that packet loss usually is not a big issue in wired network connections. Also it is stated, that "On a loss-free network, coded TCP won’t do a thing; this innovation isn’t suddenly going to boost the throughput of 802.11n networks from 300Mbps to 3,000Mbps.".
It is just a marginal amount of packet transfers that can be sped up 10 times by this technology, it's not the whole connection speed that's boosted. On a 100 mbps connection, you'd still get a maximum of 100 million bits per second in each direction.

If there was an easy way to compress traffic by ten times we'd all be doing it for years already. But how would you compress for example a packet, containing a part of a jpg or mp3 (not that you'd know about the content, anyway) by 10 times!?
If you knew, I bet you could make a fortune ;-)

Depending on the scenario you'd be better off with some proxy server, output compression on web servers, etc.
