- Raw socket support
- Nonblocking versions of all functions
- Versatile MSS and window options
- Connections limited only by memory availability
- Optional optimized assembly language checksum routines
- "Predictive" header processing for speed
- Nagle algorithm (slow start)
- VJ smoothed round-trip timing
- Delayed ACKs
- BSD style "keepalive" option
- Complete debugging and optimization module
InterNiche Technologies and Altera collaborated to provide a version of InterNiche’s NicheStack IPv4 network stack optimized for the Nios II architecture. The stack has a small footprint, is portable, and delivers high performance without compromising compliance to RFC standards. NicheStack supports a wide variety of physical interfaces, and can be configured as a standard client machine, an Internet protocol router, or a multi-homed server. The suite also contains a comprehensive device networking package, FTP, Telnet, IGMPv1, and DNS and DHCP client components.
In addition to the network stack provided by Altera, optional protocol modules are available to provide advanced networking features to the NicheStack. These modules are sold separately by InterNiche:
- SNMP protocols
- Web server
- Protocol options: PPP, PPPoE, routing, and security protocols
- TCP/IPv6
- TCP/IP dual IPv4/v6
- NAT, RIP, and DNS and DHCP servers
