AUTOSAR SOME/IP Stack

SOME/IP is a versatile and robust protocol that plays a vital role in modern automotive network architectures. It enables communication among electronic control units (ECUs) over IP on top of Ethernet network. Its service-oriented approach, combined with features like dynamic service discovery, scalability, and reliability, makes it an ideal choice for a wide range of automotive applications. As vehicles become increasingly connected and automated, SOME/IP provides flexible and efficient communication within automotive networks, ensuring the reliable exchange of services and data between various ECUs in a vehicle. Server and Client functionalities, it is an idle choice for use in both the applications.

RAPIDSEA SOME/IP stack Features

Embien offers RAPIDSEA SOME/IP protocol stack that conforms to the latest specifications of the standard. As it is built on top of a generic Internet Protocol (IP) abstraction layer, making it appropriate for use in any hardware with required networking capabilities. Offered for both Server and Client functionalities, it is an idle choice for use in both the applications.

RAPIDSEA SOME/IP protocol Stack Features

RAPIDSEA SOME/IP stack offers all the feature required for implementation such as Service Discovery, enabling services to be discovered dynamically throughout the network and Publish-Subscribe Mechanisms, allowing ECUs to subscribe to certain services and get updates or notifications when relevant data changes or on update. It also supports request-response communication patterns, allowing ECUs to send requests to other ECUs and receive responses back enabling synchronous communication between components. Our SOME/IP messages are efficiently serialized, resulting in less network traffic and faster throughput.

Specification

Specification

Our SOME/IP protocol stack is used by various clients and we have deployed them over many time. With this experience, we have created an optimal flow, where the customers can quickly incorporate and validate in their design in a matter of just half an hour. Guided by our expert team and extensive documentation, make your device speak the language of Modbus.

Features

Features

Designed and developed by architects in the automotive domain software development, our stacks are written in compliance with the standard. Optimized for both speed and size, the SOME/IP Server and Client stack has been validated both by certification software and practically in the field with hundreds of ECUs.

Licensing Model

Licensing Model

Leverage the power of low-code development without writing a single line of code to enable the Modbus functionality. With our Flint tool, developers can drag and drop the stack module, configure the registers and associated data with the convenience of the mouse. Only the data from business logic has to be updated via only 2 API's.

    RAPIDSEA SOME/IP Stack runs on top of the IP stack, which is quite common across RTOS/Baremetal and POSIX systems.

    Sure. The stack is available in source code format and can be cross compiled to platform of your choice. Then implementing the underlying IP functions, the system is SOME/IP-ready!

    Most likely, yes!We keep on updating our protocol to match the AUTOSAR specification. Except for a brief period where are working on the latest specification, our stack is latest!

    We offer it in a royalty-free model with no hidden charges whatsoever. Pay us once and you can use it for any number of products with the licensed MCU part number. If you look for alternate licenses, feel free to reach out to us.

    Embien can do the porting for you and help run the SOME/IP stack on the new target MCU.

    Yes, do not hesitate to contact us for an evaluation version of our library. While it provides all the functional features, it is a time limited version.

    Yes, we already have a Windows port that runs on top of Windows networking stack. Linux port is supported on POSIX sockets. You can easily adapt it to any hardware.

    As it is based on underlying hardware, kindly reach out to us for more information.
