In some countries, network operators employ deep packet inspection techniques to block certain types of traffic. For example, Virtual Private Network (VPN) traffic can be analyzed and blocked to ...

This paper proposes a new SRv6 End behavior, called End.AN.NF, integrating Linux netfilter as a network function for service function chaining by Segment Routing (SR). End.AN.NF allows netfilter-based ...

In order to improve the performance of Netfilter firewall framework of Linux while packets are being matched under the stateful inspection, the thesis, which is based on the analysis of the mechanism ...
