MPLAB Harmony v1.11 2 TCP/IP Stack Libraries Help TCP/IP Stack Library Overview Network Metrics TCP/IP Stack Library Overview This section provides an overview of the TCP/IP Stack libraries that are available in MPLAB Harmony. Introduction This topic provides an overview of the TCP/IP Stack in MPLAB Harmony. Description The MPLAB Harmony TCP/IP Stack provides a foundation for embedded network applications by handling most of the interaction required between the physical network port and your application. It includes modules for several commonly used application layers, including HTTP for serving web pages, SMTP for sending e-mails, SNMP for providing status and control, Telnet, TFTP, Serial-to-Ethernet, and much more. In addition, the stack includes light-weight and high-performance implementations of the TCP and UDP transport layers, as well as other supporting modules such as IP, ICMP, DHCP, ARP, and DNS. Network Metrics This topic provides TCP/IP network metrics information for PIC32MX and PIC32MZ devices. Description Network Metrics for the PIC32MX Test Setup: • PIC32 MZ Embedded Connectivity Starter Kit • PIC32 MX Ethernet Starter Kit II • Starter Kit I/O Expansion Board • Fast 100 Mbps Ethernet PICtail Plus • Windows 7 PC • TX buffer: 7350 bytes • RX buffer: 4400 bytes Iperf Bandwidth Measurements All bandwidth numbers are in kilobits per second.
