TCP/IP Networking

A solid implementation of the TCP/IP protocol suite is an absolute necessity for any product intended to deliver Wi-Fi or Ethernet connectivity. The inclusion of the Micrium OS network stack in Simplicity Studio puts TCP/IP at your fingertips and allows you to accelerate development of your connected products. The codebase of the Micrium stack has been shaped by years of customer feedback and checked for compliance using industry-standard tools.

Overview

Network Highlights

IPv4 and IPv6 implementations ready for deployment in a wide range of connected device

IPv6 support includes SLAAC, MLD, NDP, and ICMPv6

Proprietary and BSD socket functions with support for the most commonly used options

Highly configurable stack allowing unnecessary features to easily be removed

Built-in support for numerous application-layer protocols

Stack Compliance

Micrium uses Ixia’s IxANVL to confirm the compliance of the stack with the networking RFCs. IxANVL is popular among developers and manufacturers of networking equipment and internet devices for checking protocol compliance and interoperability.
