SOME/IP is an automotive/embedded communication protocol which supports remote procedure calls, event notifications and the underlying serialization/wire format.

特性：

• Serialization – transforming into and from on-wire representation.
• Remote Procedure Call (RPC) and Messaging – implementing remote invocation of functions as well as other messages.
• Service Discovery (SD) – dynamically finding and functionality and configuring its access.
• Publish/Subscribe (Pub/Sub) – dynamically configuring which data is needed and shall be sent to the client.
• Segmentation of UDP messages – allowing the transport of large SOME/IP messages over UDP without the need of fragmentation.
