Abstract
The development of Internet as well as overall communication technologies has created a very competitive communication market. In fact, there is no doubt that in the near future, every company and perhaps every person in the world will have an physical or wireless Internet access via an ISP (Internet Service Provider). Thus, the Internet became a very complex global network which represents an opportunity to provide worldwide value-added services requiring a certain level of quality of service (QoS) such as QoS-VPN (Virtual Private Network), VoD (Video On Demand). telelearning, e-Cornmerce, etc. Thus, we propose in this work to extend this approach in order to integrate new mechanisms that will allow customers to request end-to-end services. This assurance covers the QoS as well as associated parameters such as cost. The proposed solution introduces interoperability mechanisms between ISP policy based management systems and uses mobile agents to facilitate the negotiation between domains. The agent negotiation process is constrained by a set of predefined policies in order to limit the boundaries of the SLA parameters such as the cost. QoS, etc.
Highlights
The Internet became at the center of all communications between end users, customers and companies
It is recognized that end-users do not have the same expectation from the network, Some are only interested by low level quality of service (QoS) applications such as emails and are not willing to pay a lot while others, request high-level QoS for business applications, VoD, etc and are ready to pay a higher price
When the service requested by a customer span a number of ISPs' domain. a negotiation process has be launched be tween ISPs in order to set up the customer service from end to end For instance, if the customer requests a service span ning several domains, the initiating ISP hJS to search for the various routes to the destination customer access point
Summary
The Internet became at the center of all communications between end users, customers and companies. Mauro Fonseca and Nazim Agoulmine End to end IP QoS assurance using policy based multi-agents SLA management systems of the provided service and need to collaborate with peer ISPs to define the special treatment to apply to services that span their respective domain. Nowadays, this process is realized using fax and telephone and necessitates a long delay-time to allow the administrators to verify the agreed terms and to set up the network elements' configuration.
