IPv6 neighbor discovery By stretch | Thursday, August 28, 2008 at 5:03 a.m. UTC Neighbor Discovery Protocol (NDP) can be conceptualized as a toolbox used by IPv6 hosts to carry out various link-local operations. NDP itself does not describe a wire-le…

Router Solicitation Message Source Address An IP address assigned to the sending interface, or the unspecified address if no address is assigned to the sending interface. Destination Address Typically the all-routers multicast address. 源IPv6地址:在lwip中…

当内核无法查找到流表项的时候,则会通过upcall来调用用户态ovs-vswtichd中的flow table. 会调用ofproto-dpif-upcall.c中的udpif_upcall_handler函数. static void * udpif_upcall_handler(void *arg) {     struct handler *handler = arg;     struct udpif *udpif = handler->udpif;       while (!latc…

我们知道,Openvwitch可以创建虚拟交换机,而网络包可以通过虚拟交换机进行转发,并通过流表进行处理,具体的过程如何呢? 一.内核模块Openvswitch.ko的加载 OVS是内核态和用户态配合工作的,所以首先要加载内核态模块Openvswitch.ko. 在datapath/datapath.c中会调用module_init(dp_init);来初始化内核模块. 其中比较重要的是调用了dp_register_genl(),这个就是注册netlink函数,从而用户态进程ovs-vswitc…

In one embodiment, a source device detects a packet flow that meets criteria for multi-path forwarding, and forwards a probe packet on a primary path from the source device to a destination device, the probe packet carrying an indication to cause a p…
