The network map server also distributes the parameters file that define values for various settings that all nodes need
to agree on to remain in sync.
.. note:: In Corda 3 no implementation of the HTTP network map server is provided. This is because the details of how
a compatibility zone manages its membership (the databases, ticketing workflows, HSM hardware etc) is expected to vary
between operators, so we provide a simple REST based protocol for uploading/downloading NodeInfos and managing
network parameters. A future version of Corda may provide a simple "stub" implementation for running test zones.
In Corda 3 the right way to run a test network is through distribution of the relevant files via your own mechanisms.
We provide a tool to automate the bulk of this task (see below).

Additional endpoints from R3
~~~~~~~~~~~~
Network maps hosted by R3 or other parties using R3's commercial network management tools typically provide some
additional endpoints for users. These additional endpoints can be found `here <https://docs.cenm.r3.com/network-map-overview.html>`_.
HTTP is used for the network map service instead of Corda's own AMQP based peer to peer messaging protocol to
enable the server to be placed behind caching content delivery networks like Cloudflare, Akamai, Amazon Cloudfront and so on.

these parameters. There are many reasons that can lead to this decision: adding a notary, setting new fields that were added to enable
smooth network interoperability, or a change of the existing compatibility constants is required, for example.
.. note:: A future release may support the notion of phased roll-out of network parameter changes.
Updating of the parameters by the zone operator is done in two phases:
1. Advertise the proposed network parameter update to the entire network.
2. Switching the network onto the new parameters - also known as a `flag day`.
