Abstract

This paper presents personal networks, which integrate aVPN and the per-VPN execution environments of the hostsincluded in the VPN. The key point is that each executionenvironment called a portspace is bound to only one VPN,i.e., single-homed. Using this feature of portspaces, personalnetworks address several problems at multi-homedhosts that use multiple VPNs. Information flow is separatedby personal networks so that it is not mixed at multi-homedhosts. IP addressing in a personal network is independentof the other personal networks, even the base network,and therefore does not conflict with those of other networksat multi-homed hosts. In addition, personal networksprovide facilities for easy bootstrapping so that the end-userscan construct such isolated networks easily. Inheritanceof portspaces supports the creation of new portspacesbased on existing portspaces. Self-construction of personalnetworks enables end-users to construct personal networkswithout help from the base network.
