On Managing Virtual Private Networks
irtual Private Network (VPN) is one of the major trends in the integrated broadband communications environment. There is a myriad of definitions of a VPN used in the networking community to describe a broad set of problems and solutions. In [1], Ferguson et al. define a VPN as a communications environment in which access is controlled to permit peer connections only within a defined community o...
متن کاملCasual Virtual Private Networks
Virtual Private Networks (VPNs) provide a cost-effective way for securing communications using public and insecure networks like the Internet. The main purpose of a VPN is to securely and transparently connect two or more remote networks to form virtually a single network, using centralized security policies for better management and protection. However, in certain scenarios, users may not requ...
متن کاملMPLS Virtual Private Networks
This chapter is devoted to Virtual Private Networks (VPNs) designed with Multi Protocol Label Switching (MPLS) [14, 15, 1], one of the most elusive protocols of the network stack. Saying that MPLS is “elusive” is not overemphasizing: starting from its arduous fitting within the ISO/OSI protocol stack, continuing with its entangled relationships with several other routing and forwarding protocol...
متن کاملDynamic Virtual Private Networks
We extend traditional Virtual Private Networks (VPNs) with fault-tolerance and dynamic membership properties, deening a Dynamic Virtual Private Network (DVPN). We require no new hardware and make no special assumptions about line security. An implementation exhibits low overheard, provides guarantees of authenticity and conndentiality to any IP application running over the virtual network. Our ...
متن کاملPlace Oriented Virtual Private Networks
Today’s network infrastructures are inadequate to cover the needs of small groups or new requirements that popup daily from the ever-increasing demand for more sophisticated services. Place-Oriented VPNs are based on the agent technology and can be built on top of existing infrastructure by any user. We expect that in the future this flexible, dynamic and low cost approach that supports not onl...
