faudes::nDevice Class Reference

Detailed Description

An nDevice implements networked IO via a simple TCP/IP protocol.

Networking

The purpose of this implementation of networked discrete events is to provide a basis for case studies. However, simple networked events via nDevice must not be confused with ongoing research that addresses synchronisation and real time behaviour. We take a really pragmatic approach here.

Our network is identified by its network name. It consists a number of nodes, each identified by its node name. In the current implementation, each node knows about the entire network ie knows about all other nodes. Each node plays two roles:

• the server role to send event notifications, and
• the client role to receive event notifications.

In their server role, each node is configured to listen on its server port for incomming TCP connections. When a client (i.e. some other node in client role) connects to the TCP port, the server replies to a simple command set in order to allow the client to subscribe to the nodes output events. When the application executes an output event on the node, this is notified to all connected clients and the clients will interpret the event as an input reading. Vice versa, the each node itself has the role of a client and subscribes to relevant output events served by other nodes in their server role.

Protocol Details

The protocol for commands and notification is libFAUDES-token based and can be inspected eg via nc or telnet; see the shell script in the tutorial. Event notifications are sent spontaneous to all connected clients in the format <Notify> Ev </Notify>. Commands are accepted in the format <Cmd> Command </Cmd> and will be answered accordingly.

Command via TCP	Reply
<Cmd> Info </Cmd>	configuration of node as token string (<SimplenetDevice name="SimpleMachine"> ... </SimplenetDevice> )
<Cmd> Status </Cmd>	acknowledgement with status string (<Ack> Up </Ack>, <Ack> StartUp </Ack> or <Ack> ShutDown </Ack>, respectively; will not connect/reply while Down)
<Cmd> ResetRequest </Cmd>	no acknowledgement
<Subscribe> Ev_1 ... Ev_N </Subscribe>	subset of available events (e.g. <Subscribed> Ev_2 Ev_7 Ev_9 </Subscribed>)

A minimal alternative implementation for a node consists of (1) a TCP server that ignores all incomming messages and issues event notifications to any relevant events; and, (2) a TCP client that subscribes to all events and then listens to event notifications. All other commands are optional and may change in future revisions of this protocol.

Name Resolution

On the technical side, each node needs to figure the IP addresses incl TCP ports on which the other nodes provide their service. To ease configuration, this information is distributed by UDP datagrams. In order to locate the other nodes within the network, a node may broadcasts a network request datagramm. Each node that receives such a request, replies with an advert datagramm to provide its address. Thus, the simple net nodes rely on some underlying name resolution by DNS services, but node configuration itself refers to simple-net node names only. Since each node knows about the names of all participating nodes, each node will know when all connections are up.

By default, UDP broadcasts are addressed to 255.255.255.255:40000. Since routers are not meant to pass-on broadcasts, nDevice name resolution is restricted to one subnet. If the local host is connected to multiple subnets, you need to specify the relevant subset explicitly by setting the appropriate broadcast address, e.g. 192.168.2.255:40000. To restrict networks to the local machine, set the broadcast address to the loopback device 127.0.0.1:40000. To span a network accross multiple subnets, server addresses can be explicitly specified as an attribute in the node configuration; e.g. <Node> name="SimpleSupervisor" address="192.168.2.1:40000"</Node>. This is also the preferred fallback when address resolution fails for other reasons.

Broadcast via UDP	Reply
<Request> network reqnode </Request>	advertisement of networkname, nodename and ip-address:port, e.g., <Advert> SimpleLoop SimpleSupervisor 192.168.2.1:40000 </Advert>

File IO

For token IO, the nDevice reads and writes a section with label
"SimplenetDevice". There are no relevant attributes yet. Simple machine example:

<SimplenetDevice name="SimpleMachine"> 
 
<!-- Time scale in ms/ftiu -->
<TimeScale value="1000"/> 
 
<!-- IP address of this node, incl. server TCP port -->
<ServerAddress value="localhost:40000"/> 
 
<!-- Broadcaset address for node resolution (optional)
<BroadcastAddress value="255.255.255.255:40000"/> 
 
<!-- Network topology -->
<Network name="SimpleLoop"> 
<Node name="SimpleMachine"/> 
<Node name="SimpleSupervisor"/> 
</Network> 
 
<!-- Event configuration -->
<EventConfiguration> 
<Event name="alpha" iotype="input"/> 
<Event name="beta" iotype="output"/> 
<Event name="mue" iotype="output"/> 
<Event name="lambda" iotype="input"/> 
</EventConfiguration> 
 
</SimplenetDevice> 

Implementation Notes

The current status of the code is premature; network io assumes reasonably large buffers; thread/select mechanism is inefficient; exception handling wont work; etc etc
