RAPIDSEA SOME/IP protocol stack
Well proven Scalable service-Oriented MiddlewarE over IP (SOME/IP) protocol for your next-gen Ethernet powered automotive ECU development
Well proven Scalable service-Oriented MiddlewarE over IP (SOME/IP) protocol for your next-gen Ethernet powered automotive ECU development
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.
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.

Embien offers peerless technical support to quickly integrate the SOME/IP stack to your application even with challenging timelines
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.
Embien's RAPIDSEA SOME/IP stack is a full-fledged implementation of the Scalable service-Oriented MiddlewarE over IP with all the major services supported such as

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.
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.
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.
Embien offers ready-to-integrate SOME/IP protocol stacks to accelerate the in-vehicle communication functionality. Embien’s SOME/IP stack is implemented on top of the on top of standard transport layer protocols. Our SOME/IP stack is ported on IMXRT developer kit.
