"You can then use traditional encryption to your satellite provider (or take Ethernet handoff at the satellite earth station with co-located equipment, if appropriate)." True...except for most audit/regulatory purposes, having the traffic unencrypted in any part of the chain is unacceptable. "Just obtain a bigger space segment. It's literally scalable to at least ~35 megabit with ease by buying the appropriate sized pipe." True, but you have to make sure you have the right modem. The majority of modems in VSAT stacks can go up to ~10mbps. You usually have to shell out quite a bit more money to get a modem capable of handling larger bandwidths. "Otherwise, if this is not adequate you can use any traditional acceleration solution at the end sites, just check with the vendor for how optimized they are for your latency scenario." Exactly. Figuring out *what* specifically you want to accelerate is vital. Virtually any accelerator on the market can handle FTP, HTTP and other simple protocols. It takes a lot of know-how to properly accelerate some of the more complex ones. On Mon, Apr 30, 2012 at 7:58 PM, PC <paul4004@gmail.com> wrote:
Most satellite modems offer built in TCP acceleration options heavily optimized for VSAT use and an encryption option (proprietary to their hardware only) which is probably your best bet.

For various reasons, you're best not bonding. Just obtain a bigger space segment. It's literally scalable to at least ~35 megabit with ease by buying the appropriate sized pipe. Otherwise if you must bond I suggest you consider traditional ip routing mechanisms to do so on a per-flow basis.

Dear,
Could anybody recommend any hardware that can build a VPN that works well over satellite connections? (TCP enhancements)
I want to setup a L3 VPN between 2 satellite connections
Even additionally if that hardware would also support WAN bonding even better because I also have a scenario to connect 2 times 2 satellites to have more capacity for my L3 VPN
Regards,
Rens
