NGN features a complex converged network based on multiple IP technology vendors, multiple technologies, and different architectures. Softswitch plays an extremely important role in controlling such a heterogeneous network. Control is implemented through protocols. The main Protocols involved in implementing Softswitch include H.323, H.248/MEGACO, SIP, SIGTRAN, and BICC. Check five major protocols H.323 Protocol H.323 is a set of standards that provi

Analysis of key technical issues of IMS-based network convergence Font Size:SmallMediumLarge|PrintRelease: Author: webmaster Source:Network reposted: 78 timesThe emergence of Softswitch technology has led to the adoption of Softswitch technology for the integration of core control layers. However, due to the large differences in fixed and mobile Softswitch functions and protocols, Softswitch has become the focus of control layer integration. The possibility is reduced. With the emergence of

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

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

Reprint Please note: @ small Wuyi: http://www.cnblogs/xiaowuyi Using the sniff command for simple sniffing can capture some simple packages. When no interface is specified, each interface is sniffed. When an interface is specified, only this interface is used. For example; >>> sniff(filter=,count=) Result: For example, the sniffing of the ppp0 Port: >>> sniff(iface=,prn=lambda x:x.summary()) View Baidu and the result is as follows: IP/UDP 27.214.219.76: 53144> 122.225.83.67: http/RawIP/UDP/DN

ArticleDirectory Fork Module No. 1 dual-host The No. 1 dual-host service refers to the caller who calls a called phone number. Two or more calls bound to the called phone call at the same time. 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
