Virtual Networks with the IPv6 Addressing in the Xen Virtualization Environment

Abstract

Abstract. There is a common agreement that virtualization allows more efficient use of the computational and communication resources. In most cases virtualization is used on the operating systems level. Occasionally virtualization is considered on the computer network level. The paper is devoted to the virtualization of the network connections at the Layer 2 and 3 within virtualizers and real devices. For this aim the Xen 4.0 virtualizer is used. VLANs and VLAN in VLAN tunnelling (802.1ad, QinQ) are considered at Layer 2. The static as well as the dynamic routing for the IPv6-in-IPv6 tunnelling are examined at Layer 3. The aim of the paper is to present the implementation of various technologies supporting the network virtualization in the real and virtual environments.

Comparison of Resource Control Systems in Multi-layer Virtual Networks

“…In order to point advantages and disadvantages of proposed solution its functionality was compared to widespread implemented mechanisms like OpenFlow and Multiprotocol Layer Switching (MPLS). In order to choose the best solution capability of MPLS, QinQ and Provider Backbone Bridging (PBB) along with suitable traffic shaping and policing techniques was analyzed, before we decided to modify the solution described in [3], [4] to meet our requirements. This solution uses VLANs and IPv6-in-IPv6 tunneling.…”
