That's 802.3ad. Quick pointer:
http://en.wikipedia.org/wiki/Link_aggregation

You can use it between switches to use multiple links. The spec does not 
specify how to load balance the packets across the links, so link 
aggregation may not be very efficient between switches from different 
vendors. YMMV.
