Here is a really fascinating article and I picked up today on the implementation of Multipath TCP in the new Apple iOS 7.
What on Earth is Multipath TCP? Put simply it's the future of a smarter Internet. Yes, if you can believe it the Internet is about to get just that bit cleverer and being an old TCP/IP hack I think this is the most exciting thing in the protocols development since Path MTU discovery :-)
So what's the big news? It means that you will be able to switch a stream of data on your phone. mobile device or wearable tech' and switch the data stream seamlessly from 4G to 3G to the wireless in your office and back again without losing the connection. so, you could be talking on your phone on 3G walk in to your office and have the call switch seamlessly to the nearest wireless hub same thing for video streams, location-based services or anything else that will stream over the Internet.
While for many this may all seem rather 'low level' Multipath TCP play a large part in the future development of the Internet heralding a whole new era of 'smart' Internet and I foresee that it will have a massive impact on the structure, function & performance of the global infrastructure including in delivering seamless load balancing.
