Bonding has been the holy grail of Load Balancer. This term was used in the older days when a MUX (multiplexer) is used to bond multiple lines together from a single network provider.
However, it’s technically impossible in the multi-WAN, multi-provider setups. Recently, some readers emailed me about a device from Mushroom Networks which claims to be doing "real bonding". See attached advert from Google Adwords. I was so excited to find out. So I give them a call, and guess what. It's a hoax.
On closer look, the so-called real bonding technology is limited to HTTP request only. So I ask them if they can do bonding on FTP or SMTP or IMAP or just any other traffic... "NOPE". Hey! This is definitely not what bonding really is, it's just a router with a Download Manager Built-in! (DownThemAll is one which we covered earlier)
This HTTP active intercept at the router level could cause compatibility problems too. For one, what if a user runs HTTP on a port other than port 80, no "bonding".... What if an application (such as uTorrent) runs non HTTP traffic over port 80? What if a server restricts single connection to a protected/DRM content... God knows.
Be a smart customer and ask intelligent questions next time when someone claims real bonding again. At lease our informed readers, like yourself, should ask "Can it bond any Internet traffic? Or just some or one Internet protocol? Is there any chance of causing compatibility problem?"
DON'T BE FOOLED BY "REAL BONDING!"
