The application scope of VPN is increasing day by day as the organizations are creating private networks through public Internet using VPN tunneling instead of leased line. VPN protocols are classified into site-to-site and remote access VPN which exhibits different set of characteristics in terms of security mechanism. But there is no VPN preferences based on the organizational application requirements...
Click Fraud remains one of the most durable fraudulent schemes online. With 50 billion dollars being generated per year by Google alone, a fraudulent publisher is able to capture a significant amount of revenue with a small investment. The most well heeled click fraud attacks employ large distributed botnets, deceptive publisher pages, malware infection, and fake conversion “chaff” in an attempt to...
Telefonica International Wholesale Services, as many Internet Tier-1 Backbone operators, is dealing with traffic growth and its business sustainability. 2012 should be the year when 100GbE, coherent 100G transmission and Packet/OTN switching should become the cost effective solution.
On the analysis of QoS control mechanism of IMS architecture in 3GPP, this paper proposed a DiffServ-based QoS control mechanism of the IMS network, using MPLS bearing technologies, from the core network and the bearer network to achieve the end to end QoS control of IMS network.
It describes the implementation process of SIP voip call in the triple-play switch and discusses the transplantation and application of the osip stack in the Linux system, meanwhile, it proposes an embedded SIP switch application in the PSTN call processing and gives the realization diagram and solutions, which has some significance in SIP development.
There are numerous methods for identifying network traffic in recent research. In our experiment, flow is collected by using parallel probe and network IP packets are captured based on WinPcap's packet collecting technology. According to the characteristics of application layer protocol, a scalable identification system is proposed and network traffic can be classified as different application classes...
In this paper a prototype of an intelligent micropump is presented. The electrical parameters of the micropump are regulated by measuring the actual flow rate with an integrated thermal flow sensor. The micropump moves liquids with a regulated flow rate with a range of 100 μl/min to several ml/min. The accuracy is better than 10%. The micropump and flow sensor are controlled via integrated...
Even if communication networks have become increasingly ubiquitous in nature offering connections from anywhere, often most both wireless connections and especially the fixed connection at home reach a data center at an operator facility. Operators struggle to facilitate the Internet growth. We approach the topic from the perspective of our network operator partner and we ask how this operator can...
This paper concentrates on consumer devices and digital content consumption at home. We approach the topic from the perspective of our network operator partner and we ask how this operator can improve its content distribution from the current IPTV service. We propose a consumer device grid that is an integral part of the operator's IP network. Our proposal results in savings in the operator's data...
This paper addresses the original path, among Tier-1 wholesalers, carried out by Telecom Italia Sparkle in order to completely migrate from a traditional TDM-based platform to a fully IP infrastructure integrated both at the transport layer and the service layer. Focusing on the voice platform and the related OSS/BSS systems, the paper discusses on how (design criteria and achievements) the TIS integrated...
Driven by liberalization, competition, technological advances and evolving market demand, many telecom carriers consider implementing distributed network architecture, with a common, packet-based transport layer for voice and data. NGN holds the promise of offering a range of new data and multimedia services, giving the carrier access to new revenues. In migration scenarios different aspects are considered...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
