I want to just dump all the packets between two satelite links without checking for ack back and forth which creates latency and long ping times. For that I want both the peers between satelite links to take care of that and be able to deal with routing the traffic flow out again. I am not sure what solution would be appropriate for that problem and I am very open for suggestions. What I want is a solution which does not requires 3.rd party software/hardware (I am aware of the existing ones). I want it to be able to run on FreeBSD. > > > At 11:45 AM 6/15/2005 +0200, Marcin Jessa wrote: > | Hi guys. > | > | I am looking for solution I could implement on a link with a huge latency when > ping replies can go up to a few hundred miliseconds, e.g sateliete links. > | What I was thinking about is some kind of virtual interface which could > translate tcp to udp in one of the pears of the link and push the data it > received from a 'normal' interface through the virtual interface without > bothering about ack-timing. > | The receiving end would have a similar interface which would translate the udp > data stream to tcp and then route it out to the internet. > | (normal network)tcp<-->virtual udp interface<-------->virtual udp > interface<-->tcp(normal network) > | > | Is there something avaliable on FreeBSD that can be used for that purpose? > | Maybe someone is working on such a thing in CURRENT ? > | Any thoughts about that?
