Hello, in this post we are going to describe the path from switchd main() to xlate_normal_flood() in ovs-vswitchd (Open vSwitch) 2.15.90. We start with main in ovs-vswitchd.c: int main(int argc, char *argv[]) { … bridge_init(remote); free(remote); exiting = false; cleanup = false; while (!exiting) { … bridge_run();
The code in C language: ** Many thanks to my first teacher of informatics: Gazepov Georgy Affulovich! He helped me to find out the passion I have and shared with me the inspiration that leads me today. int main() { int x = 3; int y = 3; int z = 3; int i; int […]
SLAAC – a process to autoconfigure interfaces of host in IP version 6. The autoconfiguration process includes generating a link-local address, generating global addresses via stateless address autoconfiguration, and the Duplicate Address Detection procedure to verify the uniqueness of the addresses on a link. [IETF: rfc4862] Variable SLAAC – a process to autoconfigure interfaces of […]
