Multi-Platform RPC Communication
Multi-Platform RPC communication allows an agent on one platform to make RPC call on an agent in another platform without having to setup connection to the remote platform directly. The connection will be internally managed by the VOLTTRON platform router module. Please refer here Multi-Platform Communication Setup) for more details regarding setting up of Multi-Platform connections.
Calling External Platform RPC Method
If an agent in one platform wants to use an exported RPC method of an agent in another platform, it has to provide the platform name of the remote platform when using RPC subsystem call/notify method.
Here is an example:
self.vip.rpc.call(peer, 'say_hello', 'Bob', external_platform='platform2').get() self.vip.rpc.notify(peer, 'ready', external_platform='platform2')
Here, ‘platform2’ is the platform name of the remote platform.
