Overview¶

Fast Path TCP/UDP Termination IPv4 provides IPv4 TCP/UDP termination in the fast path.

Features¶

Full support of TCP and UDP sockets in the AF_INET and the AF_INET6 communication domains
Based on the call flow of *BSD TCP/IP, but redesigning the stack to scale along with any number of cores
POSIX-compliant socket API
Fully optimized for multi-core execution environments
Highly scalable processing of parallel TCP connection establishment/shutdown operations
Support of multi listening sockets bounded to a same port to achieve highly scalable parallel accept operations of TCP connections established to a given port
Highly scalable data exchanges on huge numbers of TCP/UDP sockets established TCP connections
Zero-copy based socket APIs
Sockets are VRF based, which allows overlapping of ports and IP addresses
Event driven (callbacks) notifications from the stack to the application
Plugin support for custom TCP/UDP applications
