Networking and Communication

Communications Software

Green Hills Software provides a complete and scalable suite of integrated networking products to support a broad range of network connected devices - from devices requiring basic IPv4 connectivity to those that demand the most comprehensive and robust network security and advanced routing functionality. These products were developed from the ground up to address the requirements of embedded systems spanning a range of markets, including Wireless, Automotive, Consumer, Military, Aerospace, Networking and Telecommunications. The scalable feature set and footprint can be configured to support devices from low power handsets to enterprise class routers.

The Green Hills suite of networking products is seamlessly integrated with the µ-velOSity microkernel, INTEGRITY real-time operating system, INTEGRITY-178B and MULTI development environment, providing a total solution for all your networking needs.

INTEGRITY® Networking Solutions
Green Hills Networking Solutions include industry standard inter-operable Internet protocols, routing, device management and security components. They combine the latest advances in network technology with the secure, INTEGRITY Real-Time Operating System (RTOS) family of products.

Ultimate Network Availability
For the ultimate in service availability, uptime and security, INTEGRITY offers unparalleled flexibility for protocol stack architectures requiring reliability.

  • In mission critical applications, protocol stacks and device drivers can be isolated in their own secure address spaces. This provides extra protection from network errors, alarm storms, or malicious attacks by isolating and containing areas of the system experiencing problems and allowing for fast recovering.
  • The network stack or any other application can be stopped and reloaded while the rest of the system continues to run.
  • In complex multiprocessor or blade systems, duplicate TCP/IP stacks can be configured to provide absolute isolation between an intra-system network and the Internet.
  • Redundant TCP/IP stacks can be configured for immediate traffic failover.
  • Centralized error handling, system health monitors, and INTEGRITY’s direct message passing architecture provide key building blocks for creating highly available systems.

INTEGRITY real-time operating system

Guaranteed CPU and Memory Availability

In host systems, situations of abnormal traffic like Denial of Service (DoS) attacks can severely tax buffer memory and performance, deplete resources, and ultimately crash the system. INTEGRITY has been designed with secure address spaces and resource guarantees that can be used to block this type of unintentional or malicious activity.

The GHNet TCP/IP stack, or any INTEGRITY network component, may be assigned a fixed budget of memory and CPU time resources that are guaranteed under any circumstances.

This provides guarantees that the overall system’s memory and CPU resources will not be exhausted processing network traffic in a denial of service attack, alarm storm, or other abnormal network condition.

Real-Time Performance
The GHNet TCP/IP stack has been designed specifically for high performance and real-time response. Its zero-copy interface allows the highest possible bandwidth for performance critical applications. In an embedded application, processing network traffic might not be the most critical event. The INTEGRITY TCP/IP stack never masks or blocks interrupts, even while manipulating critical data structures, ensuring minimum interrupt latency and deterministic system performance, allowing network processing to be suspended at any time to allow higher priority tasks to execute.

Security
INTEGRITY offers a secure operating system environment enhanced with a range of network security components - implementations of IETF IPv4 and IPv6 security protocols such as SSL, SSH, IPSec, IKE and RADIUS. All these offer security services such as encryption, authentication, integrity checking and replay protection. The requirements of the OEM product determine the level of security implemented.
