Signal Router

ECU communication

u The Signal Router finds a path through the network for each required information exchange.

u The Signal Router creates:

u Signals and PDUs with their Transmissions.

u An initial Communication structure (Coupling Elements with Coupling Ports and VLAN Memberships), if it does not exist.

u Socket Addresses, Application Endpoints, Network Endpoints, Consumed and Provided Service Instances.

u An initial Switch Configuration, if it does not exist (it respects existing Switch Configurations).

22

Socket Connections

ECU communication

u The Server socket refers to a [socket connection bundle] which contains many [socket connections] to client sockets.

u Each socket connection then contains the included PDU Transmissions.

u A table action propagates the IDs from the service definition down to PDU transmissions.

u The second editor displays the content of a bundle (for multicast events).

23

Data Serialization

ECU communication

u Data serialization tracks the signals caused by the service interface.

u The transformer holds information on byte order or constraints.

24

End to End Protection and Transformation

Support for SOME/IP, E2E and generic transformer

Socket based communication in IP networks

u Communication end-point instance is called “network socket”

u Datagram socket (UDP)> Connectionless (datagram)

u Stream Socket (TCP)> Connection oriented (session)

> Connection setup, connection teardown

u Addressing over 4-tuple

{Source IP Address: Source Port, Destination IP Address: Destination Port}

u Addresses may be fixed or change dynamically during runtime

u Depending on socket type, transmitted information and also connections can be changed dynamically during runtime

u On this level no semantical or syntactical information about the payload is assumed

u An Ethernet socket is defined by the following aspects

u IP Address

u Transport Protocol

u Port (Port Number is an attribute of the TP)

u Sockets provide the Application Endpoint

u Sockets can be unicast or multicast, depending on their TP (and IP)

Signal Router on Ethernet

u The Signal Router finds a path through the network for each required information exchange.

u It synthesizes communication artefacts.

u It can be started from…

u the context menu of Software Compositions or ports.

u from the Service Provider Roles in both Editors of the Service Deployment Category (uses latest settings; run from context menu to adjust settings).
