This Corda network offering builds a pre-configured network of Corda nodes as Ubuntu virtual machines (VM). The network comprises of a Network Map Service node, a Notary node and up to nine Corda nodes using a version of Corda of your choosing. The following guide will also show you how to load a simple Yo! CorDapp which demonstrates the basic principles of Corda. When you are ready to go further with developing on Corda and start making contributions to the project head over to the `Corda.net <https://www.corda.net/>`_.

PersistentNetworkMapService and NetworkMapService

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

PersistentNetworkMapService
|

~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The ``NetworkMapService`` is a node internal component responsible for
|
||||
managing and communicating the directory of authenticated registered
|
||||
nodes and advertised services in the Corda network. Only a single node
|
||||
in the network (in future this will be a clustered service) should host
|
||||
the NetworkMapService implementation. All other Corda nodes initiate
|
||||
their remote connection to the ``NetworkMapService`` early in the
|
||||
start-up sequence and wait to synchronise their local
|
||||
``NetworkMapCache`` before activating any flows. For the
|
||||
``PersistentNetworkMapService`` registered ``NodeInfo`` data is
|
||||
persisted and will include nodes that are not currently active. The
|
||||
networking layer will persist any messages directed at such inactive
|
||||
The ``PersistentNetworkMapService`` keeps track of ``NodeInfo`` and
|
||||
persists it to the database. It and will include nodes that are not currently active.
|
||||
The networking layer will persist any messages directed at such inactive
|
||||
nodes with the expectation that they will be delivered eventually, or
|
||||
else that the source flow will be terminated by admin intervention.
|
||||
An ``InMemoryNetworkMapService`` is also available for unit tests
|
||||
without a database.
|
||||
|
||||
The ``NetworkMapService`` should not be used by any flows, or
|
||||
contracts. Instead they should access the NetworkMapCache service to
|
||||
access this data.
