Here are some of the conditions for handling ARP packets: Criteria for discarding packets: 1, arp_process only processing request, reply ARP packet, discard other types of packets A for packets of type request, the discarded destination address is either multicast or loopback ARP data. For data packets that need to be processed, they can be divided into several areas: 1. Processing of reply packets for

Osip2 is an open-source sip protocol stack, which is not frequently written in C language in open source code. It has the characteristics of being short and concise, focusing on the underlying parsing of sip makes it more efficient. EXosip is an extended protocol set of Osip2. It partially encapsulates the Osip2 protocol stack, making it easier to use. I. Introduction Osip2 is an open-source

Either of them can answer the call first. After the first call, the other calls will stop ringing. Most of the functions implemented by traditional switches are implemented on the intelligent network platform (in), which can be easily implemented on the softswitch platform such as Yat
