 In addition to this core functionality FairMQ provides a framework for creating "devices" - actors which
 are communicating through message passing. FairMQ does not only allow the user to use different transport but also to mix them; i.e: A Device can communicate using different transport on different channels at the same time. Device execution is modelled as a simple state machine that

 Multiple Transports example

+This example demonstrates use of multiple transports (zeromq/shmem) within the same topology and/or device. It is a simple topology consisting of two samplers and a sink. The devices are connected via 3 channels:
 
 ![Multiple Transports example](../../docs/images/example_multiple_transports.png?raw=true "Multiple Transports example")
 
 Each device has main transport that it uses. By default it is ZeroMQ, and can be overriden via the `--transport` cmd option. The device will initialize additional transports if any of the channels have them configured (e.g. as an option to `--channel-config`).
 
-In this example sampler1 and sink are started with `--transport shmem`, making shared memory their main transport, sampler2 with `--transport nanomsg`. Additionally, the ack channel is configured to use zeromq as its transport.
+In this example sampler1 and sink are started with `--transport shmem`, making shared memory their main transport, sampler2 with `--transport zeromq`. Additionally, the ack channel is configured to use zeromq as its transport.
 
 The main two things that a transport does is transfer of data and allocation of memory for the messages. By default, new messages are created via the main device transport. If a message has been created with one transport and is to be transferred with another, it has to be copied into a new message of the target transport. This happens automatically behind the scenes. To avoid this copy the device can create messages via `NewMessageFor(const string& channelName, int subChannelIndex, ...)` method, that creates the messages via the transport of the given channel (check sampler1 and sink for an example) or as the channel directly to create a message.

 With FairMQ several generic devices are provided:
 
-- **FairMQBenchmarkSampler**: generates random data of configurable size and at configurable rate and sends it out on an output channel.
-- **FairMQSink**: receives messages on the input channel and simply discards them.
-- **FairMQMerger**: receives data from multiple input channels and forwards it to a single output channel.
-- **FairMQSplitter**: receives messages on a single input channels and round-robins them among multiple output channels (which can have different socket types).
-- **FairMQMultiplier**: receives data from a single input channel and multiplies (copies) it to two or more output channels.
-- **FairMQProxy**: connects input channel to output channel, where both can have different socket types and multiple peers.
