The Ethereum Wire protocol defines the communication between the nodes running Ethereum. Further reader reading can be done on the Wiki.

Reading Messages

// returns a error message with the details.
msg, err := ethwire.ReadMessage(conn)
if err != nil {
  // Handle error
}

Writing Messages

// Constructs a message which can be interpreted by the eth network.
// Write the inventory to network
err := ethwire.WriteMessage(conn, &Msg{
  Type: ethwire.MsgInvTy,
  Data : []interface{}{...},
})
