7TCF: The Target Communication Framework | © 2008 Wind River; made available under the EPL v1.0 | Eclipse Summit Europe | Nov 2008 Limited eco system Too many different tools agents and protocols

8TCF: The Target Communication Framework | © 2008 Wind River; made available under the EPL v1.0 | Eclipse Summit Europe | Nov 2008 Design Goals of TCF Framework provides common infrastructure  communication protocol  Agent: “Service container”  Proxying Tools can use services in uniform way Service implementers can focus on functionality

9TCF: The Target Communication Framework | © 2008 Wind River; made available under the EPL v1.0 | Eclipse Summit Europe | Nov 2008 TCF - Core Design Ideas Service knows best how to represent the system  get information from there and data-drive layers above  If not possible, put the knowledge in the lowest possible layer and data drive the layers above Use the same protocol end-to-end  allow value-adding servers to intercept select services Services as building blocks  E.g. target agent, OCD, simulator  Avoid tools specific agents Support high latency communication links

14TCF: The Target Communication Framework | © 2008 Wind River; made available under the EPL v1.0 | Eclipse Summit Europe | Nov 2008 Channels and Messages Communication between peers use channels Channels abstract/hide the transport layer  Currently TCP  Possible: RS232, JTAG, USB etc Channels transmit Messages

15TCF: The Target Communication Framework | © 2008 Wind River; made available under the EPL v1.0 | Eclipse Summit Europe | Nov 2008 TCF Communication Protocol Message  A packet of data  Transmitted over communication channel Multiple channels per peer Proxying/Tunneling  Message forwarding  “Decorator” can intercept communication  “Value-add” services (e.g. debug info)  No protocol conversion needed

16TCF: The Target Communication Framework | © 2008 Wind River; made available under the EPL v1.0 | Eclipse Summit Europe | Nov 2008 The TCF Message Types Command (send)  Request some action on remote peer Progress  Long running commands may send “progress ticks” Result (reply)  Remote peer sends one result for each command! Event  Notify a change Flow control  prevent congestion

17TCF: The Target Communication Framework | © 2008 Wind River; made available under the EPL v1.0 | Eclipse Summit Europe | Nov 2008 Command Command is a message Sent to remote peer Remote peer must send one Result for each Command!

18TCF: The Target Communication Framework | © 2008 Wind River; made available under the EPL v1.0 | Eclipse Summit Europe | Nov 2008 Result Result is a message  Data, Errors Sent as a response to a command Remote peer sends one Result per Command!

19TCF: The Target Communication Framework | © 2008 Wind River; made available under the EPL v1.0 | Eclipse Summit Europe | Nov 2008 Commands are Asynchronous Sender of a command returns immediately  Fast on high latency connections Sender receives results  asynchronously

20TCF: The Target Communication Framework | © 2008 Wind River; made available under the EPL v1.0 | Eclipse Summit Europe | Nov 2008 Event Event is a message Notification about state changes

21TCF: The Target Communication Framework | © 2008 Wind River; made available under the EPL v1.0 | Eclipse Summit Europe | Nov 2008 Message order guaranteed on channel Keep state of remote peer Without message ordering no consistent state Ordering per channel and direction Command X=1 Result X=1 Event X=2 Command X=3 Event X=4 Result X=3 Event X=5
