N2N: a Layer Two Peer-To-Peer VPN
N2N: A Layer Two Peer-to-Peer VPN Luca Deri1, Richard Andrews2 ntop.org, Pisa, Italy1 Symstream Technologies, Melbourne, Australia2 {deri, andrews}@ntop.org Abstract. The Internet was originally designed as a flat data network delivering a multitude of protocols and services between equal peers. Currently, after an explosive growth fostered by enormous and heterogeneous economic interests, it has become a constrained network severely enforcing client-server communication where addressing plans, packet routing, security policies and users’ reachability are almost entirely managed and limited by access providers. From the user’s perspective, the Internet is not an open transport system, but rather a telephony-like communication medium for content consumption. This paper describes the design and implementation of a new type of peer-to- peer virtual private network that can allow users to overcome some of these limitations. N2N users can create and manage their own secure and geographically distributed overlay network without the need for central administration, typical of most virtual private network systems. Keywords: Virtual private network, peer-to-peer, network overlay. 1. Motivation and Scope of Work Irony pervades many pages of history, and computing history is no exception. Once personal computing had won the market battle against mainframe-based computing, the commercial evolution of the Internet in the nineties stepped the computing world back to a substantially rigid client-server scheme. While it is true that the today’s Internet serves as a good transport system for supplying a plethora of data interchange services, virtually all of them are delivered by a client-server model, whether they are centralised or distributed, pay-per-use or virtually free [1]. -

Paravirtualization (PV)
Full and Para Virtualization Dr. Sanjay P. Ahuja, Ph.D. Fidelity National Financial Distinguished Professor of CIS School of Computing, UNF x86 Hardware Virtualization The x86 architecture offers four levels of privilege known as Ring 0, 1, 2 and 3 to operating systems and applications to manage access to the computer hardware. While user level applications typically run in Ring 3, the operating system needs to have direct access to the memory and hardware and must execute its privileged instructions in Ring 0. x86 privilege level architecture without virtualization Technique 1: Full Virtualization using Binary Translation This approach relies on binary translation to trap (into the VMM) and to virtualize certain sensitive and non-virtualizable instructions with new sequences of instructions that have the intended effect on the virtual hardware. Meanwhile, user level code is directly executed on the processor for high performance virtualization. Binary translation approach to x86 virtualization Full Virtualization using Binary Translation This combination of binary translation and direct execution provides Full Virtualization as the guest OS is completely decoupled from the underlying hardware by the virtualization layer. The guest OS is not aware it is being virtualized and requires no modification. The hypervisor translates all operating system instructions at run-time on the fly and caches the results for future use, while user level instructions run unmodified at native speed. VMware’s virtualization products such as VMWare ESXi and Microsoft Virtual Server are examples of full virtualization. Full Virtualization using Binary Translation The performance of full virtualization may not be ideal because it involves binary translation at run-time which is time consuming and can incur a large performance overhead. -
Virtual Private Networ Ks
5 Virtual Private Networ ks 5.1 Introduction In Part 2, we discuss virtual private networks (VPNs). Chapter 4 had some examples of VPNs, but we were interested mainly in their tunneling aspects and didn’t dwell on their security and authentication features. In this chapter, we define VPN and briefly revisit the VPNs from Chapter 4. In the rest of Part 2, we study several types of VPNs, see how they are used, and take note of their strengths and weaknesses. As we shall see, these VPNs can operate at any layer in the TCP/IP stack. As usual, we will be less concerned with the administrative details of configuring the VPNs than with developing an appreciation for the protocols them- selves and the manifestation of those protocols on the wire. Before beginning our discussion of VPNs, we should agree on a definition for them. We already have an implicit definition from our study of MPLS VPNs in Chapter 4. We might say that according to that definition, a VPN is a method of using tunneling to build a private overlay network on top of a public network in such a way that the secu- rity of the private network is equivalent to that provided by leased lines. But this defi- nition suffers from a lack of precision as to the meaning of ‘‘security equivalent to that provided by leased lines’’ and is a bit too general for our purposes. Instead, let us say that a virtual private network is an overlay network built with tunnels in which the tunnel payloads are encrypted and authenticated.
