摘要：Mobile applications and mobile application environment of next generation networks require enhanced quality of service (QoS) to support user's service level agreement (SLA). This paper presents an adaptation technique at transport layer to minimize the impact of va rying and adverse network condition along with security and priority to satisfy the SLA. The paper extends the transport layer functionalities to manage the SLA by selecting network layer parameters and application layer parameters. The given approach provides a performance based on the analysis of mapping network layer and application layer availability and security to network concerned paramet ers like security and priority by using fuzzy rules. Network parameters scrutinize at transport layer to get the information about speed, delay, jitter and loss. Application layer provides information such as priority, security to the extended functionalities of transport layer. The objective is preserving the QoS perceived as per SLA at an acceptable level
