9.1.2 Network Stack

The Network Stack features are as follows:

  • Integrated IPv4, IPv6 TCP/IP stack with BSD (BSD adjacent) socket APIs for simple Internet connectivity with any MCU, microprocessor, or ASIC
    Note:

    Not all APIs are 100% BSD compliant. Not all BSD APIs are supported.

  • Support of 16 simultaneous TCP, UDP, or RAW sockets
  • Support of 6 simultaneous SSL\TLS sockets
  • Built-in network protocols:
    • Static IP, LLA, DHCPv4, DHCPv6 with DAD and stateless autoconfiguration
    • ARP, ICMPv4, IGMP, ICMPv6, MLD, ND
    • DNS client for easy connection to the local network and the Internet
  • Built-in network application and utilities:
    • HTTP/HTTPS
      • Web page content stored on serial Flash
      • RESTful APIs for setting and configuring application content
      • Dynamic user callbacks
    • Service discovery: Multicast DNS service discovery lets a client advertise its service without a centralized server. After connecting to the access point, the CC3120R device provides critical information, such as device name, IP, vendor, and port number.
    • DHCP server
    • Ping
