The continued trend of globalization and technology improvement like the internet and transportation have spawned an increasing number of complex service chains that span across local, regional and national boundaries. Service level agreement (SLA) plays a crucial role in gluing service chains together. In that regard, this paper provides a complete guidance of end-to-end lifecycle management of SLA, including SLA-aware service modelling and terms optimization, contract drafting and compliance tracking. Among these, the author introduces his work in the area of enterprise SLA optimization to address existing deficiencies in this area including a roadmap for industry-strength SLA optimization capability and an initial version of SLA modeling and optimization toolset—code-named SLA-OASIS. Some out-of-box toolsets for SLA contract drafting and compliance tracking are also introduced.

The Impact

End to End Quality of Service is a way to provide data package service in a telecommunication network that based on Right Price, Right Service Level, and Right Quality. The goal of this research is to analyze the impact of End to End QoS use on 3G telecommunication network for voice service and data. This research uses an analysis method by doing the application on the lab. The result that is achieved in this research shows that End to End QoS is very influental to the Service Level Agreement to the users of the telecommunication service.Keywords: End to End Qos, SLA, Diffserv

This paper examines the availability of Internet services in Higher Learning Institutions (HLIs) for developing countries such as Ghana, with respect to the cost and usage. We looked at the source of Internet services and the bandwidth package for some Higher Learning Institutions in Accra, Ghana. One of the key objectives of this study is to design and simulates an efficient Internet bandwidth usage for Higher Learning Intuitions. We examined the cost of bandwidth package offered by the Internet service providers to these higher institutions. In looking at the cost we also included the bandwidth packages offered, the type of Internet connection and the service level agreement with the ISPs. In the study, we looked at how the Internet is distributed to these institutions and the equipment used in the distribution of the Internet services. Ipswich Whatsup Gold software was used to monitor the network infrastructure for one of the institutions in the study. We went further to monitor the bandwidth consumption for Ghana Technology University College, one of the institutions in the study, to monitor their bandwidth consumption and traffic flow in the network. In designing an efficient bandwidth management for the Higher Learning Institution, we model and configured a network in Packet tracer using a proxy cache box. This technique allows for an efficient bandwidth planning capacity to manage the bandwidth consumptions. At the end of the study, we modeled a network using cache box to restrict and minimize bandwidth usage and thus making it less expensive for the Higher Learning Institutions.

Private Network

Compliance with the Service Level Agreement (SLA) metric is a major challenge in a Multiprotocol Label Switching Virtual Private Network (MPLS VPN) because mandatory models must be maintained on both sides of the MPLS VPN in order to achieve end-to-end service levels. The end-to-end service of an MPLS VPN can be degraded owing to various issues such as distributed denial of service (DDoS), and Random Early Detection (RED) that prevents congestion and differentiates between legitimate and illegitimate user traffic. In this study, we propose a centralized solution that uses a SLA Violation Detector (SLAVD) and intrusion detection to prevent SLA violation.
