<p>Methods and apparatus are disclosed for communicating between a first node and a second node across a data network. According to one aspect, the method comprises, at the second node: communicating with the first node via a primary communication flow, data in the primary communication flow being capable of interpretation according to a first communication protocol; receiving data from the first node via a secondary communication flow; identifying in dependence on the secondary communication flow a protocol change indication, the protocol change indication indicating to the second node that data units being sent via the primary communication flow are capable of interpretation according to a second communication protocol different from the first communication protocol; and communicating with the first node via the primary communication flow using the second communication protocol.</p> |
