User adaptation is a critical and important problem. For users' specialization, such as Handwriting, Voice,Drawing Styles, the system is hard to adapt to all users. SVM-based incremental learning can find the most basic fea-ture of different users and cast away the special user's character, so this method can adapt the different users withoutover fitting. In this paper, the repetitive learning strategy and other two incremental learning algorithms are presentedfor comparison. Based on theoretical analysis and experimental results, we draw the conclusion that SVM-based incre-mental learning can solve the user conflict problem.

Constructing Virtual Private Network (VPN) over public network infrastructure (Internet) is becoming the foundation of the next generation network service. At present, VPN mainly focuses on the security property, while it is lack of consideration of QoS. On the basis of analyzing the Differentiated Services (Diffserv) and IPsec, we put forward a QoS-based IP VPN Architecture Model which is a tri-tier model that is composed of ESN, ISN and VPN node. It combines encrypted channel mechanism of IPsec and the edge-and-core-model of Diffserv. It provides end-to-end QoS while assures security.
