C.5.1 Functional Components

End To End Communication

Description The End To End Communication FC takes care of the whole
End To End Communication abstraction, meaning that it takes
care of reliable transfer, transport and, translation
functionalities, proxies/gateways support and of tuning
configuration parameters when the communication crosses
different networking environments. The FC relates to a (IoT)
Service and to the Network Communication FC.

Transmit
Message

The function allows transmitting a message from

Network Communication FC to End To End

Communication FC and from (IoT) Service to End To

End Communication FC. This function is executed

by the End To End Communication FC and can be

called by a (IoT) Service or by the Network

Communication FC. The arguments for the

message can be set in this function or through the

Configure Message Arguments function described

below.

C.5.3

Configure
Message
Arguments

This function configures the message arguments for

the Transmit Message Function. Examples of

arguments include: reliability, integrity, encryption,

access control and multiplexing. This function is

executed by the End To End Communication FC and

can be called by an IoT Service or by the Network

Communication FC.

C.5.3

Cache and
Proxy

The Cache and Proxy function allows buffering

messages in the End To End Communication FC.

It‘s an internal function with no exposed interface
