We consider the problem of transport state handoff in mobile networks. The problem is motivated by the observation that an efficient way to implement transport connections, where one end is mobile, is to split these connections in two at a node close to the mobile. In such an environment we need to ensure that transport state can be handed off to a new intermediate node if the mobile roams to a location far away from the location where the connection(s) were opened. Our handoff protocols are efficient and we show that they work correctly despite any sequence of moves made by the mobile.
