The paper proposes a methodology to provide services for accessing and sharing various media contents securely, those are distributed over consumer electronics (CEs) in the home network. To do so, we propose the DLNA Proxy System (DPS) architecture which helps to gather various media information available from the distributed AV devices in the home and to share the media contents across the public IP network via established secure channels. The proxy system is implemented on the home server which acts as media server and the hardware accelerated IP Security (IPSec) Virtual Private Network (VPN) is configured on the home gateway which establishes and maintains secure connections between the home and public networks (1). Index Terms--Home Network, DLNA, Media Sharing, Home Server, Home Gateway, IPSec VPN.

Secure sockets layer (SSL) virtual private networks (VPN) are emerging as alternatives to traditional VPNs.

Virtual private networks have been around for a long time. We didn't always call them VPNs, but companies have been sending their private data over public services like X.25, frame [...]

Network managers should have a general understanding of the functions of virtual private networks (VPNs) and their technical relationships before selecting the one that is most appropriate for their needs. At the heart of a VPN is a tunnel protocol which encapsulates user data prior to transporting them over the Internet. Point-to-Point Tunneling Protocol heads the list of tunneling protocol but alternatives consist of the IP Security, Layer 2 Tunneling Protocol and Socks. Of the four, L2TP and PPTP have the ability to manage and negotiate additional VPN functions., Before you start digging that VPN tunnel, you need to choose the right pick and shovel. Here's a protocol primer. IP-based virtual private networks (VPNs) offer a promising alternative to [...]

Virtual private networks offer some serious savings--if you know the secret. Do you always get what you pay for? Buy a Lexus, get reliability. Buy a Yugo, get a future […]

Distributed Virtual Simulation (DVS) is a military training technology which adapts Virtual Reality for networking applications. To implement it on the Internet, certain technologies for supporting real-time networking, multicast packet communications and network resource reservation are required. These pertain to networking protocols, security architecture, interface to the asynchronous link layer and network management.

Building a layer 2 VPN extranet is complicated and expensive. Although IP-based solutions promise a more cost-effective and scalable approach, service providers will have to reassure customers that QoS and […]
