Abstract

Innovation in the network is notoriously difficult due to theneed to support legacy applications. We argue that this difficultystems from the API used to access the network. Theubiquitous Sockets API lets applications choose from a numberof communication mechanisms, but binds them tightlyto their chosen mechanism (e.g. specifying a destination usingIPv4). Applications must therefore be modified in orderto benefit from new network technologies. To addressthis problem, we propose a new communication API calledNetAPI that lets applications specify their communicationintents without binding to particular network mechanisms,enabling evolution below the API. We have built a NetAPIprototype for the iPhone, and use it to show that we can adddisconnection tolerance, content shaping and power savingpolicies under NetAPI without application modifications.
