Enterprise and service provider customers develop, maintain and operate network infrastructure in order to support the applications required to perform their day to day tasks. These applications have certain requirements and expectations from the infrastructure, including access to public networks, and thus rely on quality of service (QoS) controls to manage network traffic. QoS controls are used...
Service overlay networks (SONs) have recently been proposed to support various value-added services including multicast, resilient routing, QoS support, and DoS resistant communication in the Internet. Access control plays an important role for various SON applications yet most SON proposals do not consider access control or assume that it is a pre-existing service. The lack of a proper access control...
For an improved QoS provisioning, operators are strongly concerned both with the availability and the reliability of their performance critical servers. Among these entities, we mention the firewalls used to filter the offered network traffic to the operator's information system as well as the end processing servers which service each incoming client request. In this work, we advocate and evaluate...
As computer networking grows more important in daily usage, its security is also paramount. Network intrusion detection system (NIDS) observes network traffic for identifying malicious packets. Core to NIDS function is packet classification component. It is in charge of scanning network packet header. An improved packet classification component bears direct result for NIDS performance. This paper...
