IP Telephony provides a way for an enterprise to extend consistent communication services to all employees, whether they are in main campus locations, at branch offices, or working remotely, also with a mobile phone. IP Telephony transmits voice communications over a network using open standard-based Internet protocols. This is both the strength and weakness of IP Telephony as the involved basic transport protocols (RTP, UDP, and IP) are not able to natively guarantee the required application quality of service (QoS). From the point of view of an IP Telephony Service Provider this definitely means possible waste of clients and money. Specifically the problem is at two different levels: i) in some countries, wherelong distance and particularly international call tariffs are high, perhaps due to a lack of competition or due to cross subsidies to other services, the major opportunity for IP Telephony Service Providers is for price arbitrage. This means working on diffusion of an acceptable service, although not at high quality levels; ii) in other countries, where different IP Telephony Service Providers already exist, the problem is competition for offering the best possible quality. The main idea behind this chapter is to analyze specifically the state of the art playout control strategies with the following aims: i) propose the reader the technical state of the art playout control management and planning strategies (overview of basic KPIs for IP Telephony); ii) compare the strategies IP Telephony Service Provider can choose with the aim of saving money and offering a better quality of service; iii) introduce also the state of the art quality index for IP Telephony, that is a set of algorithms for taking into account as many factors as possible to evaluate the service quality; iv) provide the reader with examples on some economic scenarios of IP Telephony.

Draw on the trust relationship of human society, domain model and domain trust are introduced to build domain-based level trust manage model (DLTMM). In various domains, according to physical services characteristics of their own, entities abstract representative attribution. According to their preferences the service requester preferences comprehensive evaluate the service attributions, and to determines whether transaction; After trading, the service requester will calculate the difference degree of quality of service according to the actual quality of service and the claimed quality of service, and then judge the trust degree of service provider. The simulation results show that the model can more accurate assessment of the trust entity, to some extent effective against malicious attacks, which proves the validity and accuracy of the model.

Java Code

Web services are programs which perform some elementary business process of an application and are distributed over the Internet. These services are described, discovered and executed using standard languages WSDL, SOAP and UDDI. Proliferation of web services has resulted in intense competition between providers, which provide the same service. To survive in such a competitive environment, they need to advertise the quality of their service. Web service description language does not provide support to describe quality attributes. Recently, DAmbrogio proposed QOS model of web services based on a meta model of WSDL. In this paper, we present a platform to advertise QOS as declared by the service provider. This tool generates a WSDL file from Java code along with its quality of service attributes. It accepts Java code and a file containing quality attributes. These attributes include reliability, availability, and operation demand and operation latency. These attributes are included in WSDL file as a content of description element.

Abstract— Bandwidth is a carrying capacity of data carriers on a network connection, using units of time in speed. The cost of bandwidth procurement is very expensive and if it is not set up with management and hardware support, good software or brainware will cause huge losses. Therefore, a quality service standard must be created in an Internet Service provider known as Quality of Service (QoS). On a Cisco Router there are several methods of Quality of Service configured in such a way that the bandwidth of an ISP can be restricted and well managed. Traffic Policing and Traffic Shaping are two methods of Quality of Service that are widely used and each has advantages and disadvantages in terms of technical and non technical. In this research will answer the use of the best Quality of Service method on Cisco ISP Router by using descriptive analysis through Quality of Service data analysis parameters. Index Terms— Bandwidth, Quality of Service

Cloud computing is the most utilized and evolving technology in the past few years and has taken computing to a whole new level such that even common man is receiving the benefits. The end user in cloud computing always prefers a cloud service provider which is efficient, reliable and best quality of service at the lowest possible price. A cloud based gaming system relieves the player from the burden of possessing high end processing and graphic units. The storage of games hosted in clouds using the latest technologies in cloud has been discussed in detail. The Quality of service of games hosted in cloud is the main focus of this chapter and we have proposed a mathematical model for the same. The various factors in dealing with the quality of service on cloud based games have been analyzed in detail. The quality of experience of cloud based games and its relation with quality of service has been derived. This chapter focuses on the various storage techniques, quality of experience factors and correlates the same with QoS in cloud based games.

AbstractIn principle, all data on the Internet have so far been transmitted on the basis of best-effort, i.e. equally and without change, regardless of content, service, application, origin or destination. Quality of Service (QoS) has not been excluded, but has instead generally been limited to the access network of the Internet Service Provider (access-ISP) (IPTV, VoIP etc.). Now, the ISPs plan to offer such a QoS on the Internet as well by means of various prioritised transport groups. These QoS transport groups are not supposed to displace, but rather to complement the best effort area (QoS and best effort). Hereby the ISP first expect to participate more in the added value of the Internet. Secondly, the problems caused by the bottleneck for timecritical services and other forms of QoS (IPTV, VoIP, gaming etc.) are to be eliminated. Thirdly, various transport groups and various groups of products (IPTV, VOD, interactive services such as gaming etc.) characterised by specific technical features of performance and features of quality are to be composed and marketed by the ISP to the content provider, to the service provider and to the consumer. In order to guarantee such QoS on the Internet, the ISP have to agree on cross-network technical standards for QoS.Both the European Commission and the German legislator, being competent for transposing the EU directives on telecommunications into national law, take a careful approach to the issue of network neutrality. For the case that ISP limit the access or the use of services the directives provide for transparency rules aimed at guaranteeing the comsumer’s freedom of choice. Beyond that, minimum requirements for the quality of service can be set in order to prevent impairment of services and hindrance or slowdown of data traffic in the nets. Hereby consumers are protected comprehensively. As it stands more regulation is not necessary. The risk of discrimination coming from vertical integration can be addressed by means of sector-specific regulatory law (cf. § 42 German Telecommunications Act - TKG) and by means of general competition law (cf. §§ 19, 20 Act Against Restraints of Competition - GWB, Article 102 Treaty on the Functioning of the European Union - AEUV). The composition of the various QoS transport groups and marketing to the content provider, to the service provider and to the consumer do not as such give rise to a need for regulation. In fact, the formation of (cross-network) QoS transport groups constitutes a pre-condition for consumers booking such QoS on the Internet. However, all content providers and service providers seeking access to QoS transport groups must have such access according to non-discriminatory terms. Such non-discriminatory access can be adequately guaranteed by sector-specific regulatory law and general competition law. At present, subject to the condition of there being a robust and dynamically developing best effort area in addition to QoS transport groups, more regulation is not necessary. However, it cannot be predicted whether the different QoS transport groups will emerge or not. Regulation „at random“ is as pointless as „symbolic regulation“.

Loyal Customers

Having more solely loyal customers (those who only use one supplier) is an aspiration for most service providers. Yet, it is unclear whether, or in what way, solely loyal customers differ from customers whose loyalty is divided between more than one service provider. One loyalty indicator is a consumer's evaluation of the quality of service they receive. Using seven sets of cross-sectional data, this research reveals that solely loyal customers give, on average, approximately 10% more positive service quality evaluations than customers of the same provider who also use other providers. The implication of this finding for market researchers and practitioners is that service quality scores could be moderated by the distribution of solely loyal and multiple-provider users in a given sample. Therefore, every service quality survey should measure how many providers a customer uses and control for the proportion of solely loyal customers when tracking change using cross-sectional samples.
