Though Windows Meeting Space is typically used on a single local area network (LAN), the feature supports meeting sessions that cross subnets or even span the Internet. By allowing each host to have a unique address, IPv6 ensures that all Windows Meeting Space users can ultimately connect to each other without conflict. In the IPv4 world, the lack of available addresses has prompted the use of network address translation (NAT) devices that assign private, or hidden, addresses to each host; unfortunately, these private IPv4 addresses are not globally unique or routable, so client hosts cannot communicate with each other easily.</font></li> <li style="margin: 0.0px 0.0px 3.0px 0.0px; line-height: 15.0px"><font face="Verdana" size="3" style="font: 11.0px Verdana"><b>Improved connectivity</b>: IPv6 facilitates improved end-to-end connectivity, enabling Windows Meeting Space sessions over the Internet. Microsoft Windows provides technologies such as Teredo and 6to4 that enable end-to-end IPv6 connectivity over the existing IPv4 Internet. Teredo allows IPv6-aware hosts to tunnel traffic to each other over the IPv4 Internet; Teredo is able to operate transparently through most existing NAT devices and home gateways. Teredo connectivity is transparent to IPv6 application developers, meaning that developers are freed from the worries of manual NAT traversal. On the other hand, IPv4 developers must often build and deploy custom NAT traversal techniques within their applications. The 6to4 protocol allows an Internet-connected host or router (such as a next-generation home gateway device) with a public IPv4 address to tunnel traffic over the IPv4 Internet. Again, the presence of 6to4 connectivity is transparent to application developers.</font></li> <li style="margin: 0.0px 0.0px 3.0px 0.0px; line-height: 15.0px"><font face="Verdana" size="3" style="font: 11.0px Verdana"><b>Automatic address configuration</b>: IPv6 enables Windows Meeting Space to deliver a fast and smooth ad-hoc networking experience. For each active network interface, clients automatically generate a unique link-local IPv6 address (suitable for communicating with other hosts on the subnet) without relying on the presence of a router or DHCP server to centrally assign addresses on that network. This address allocation scheme ensures that hosts can begin to communicate without any delay upon creating an ad-hoc wireless network or upon plugging into a network hub or switch. Although IPv4 supports ad-hoc networking, automatic network setup is traditionally slow.</font></li> <li style="margin: 0.0px 0.0px 3.0px 0.0px; line-height: 15.0px"><font face="Verdana" size="3" style="font: 11.0px Verdana"><b>Native support for security (IPsec)</b>: IPv6 provides native support for IPsec, allowing Windows Meeting Space to operate efficiently over both insecure and secure IP networks. Increasing numbers of enterprises are deploying IPsec to enable Server and Domain Isolation.</font></li> <li style="margin: 0.0px 0.0px 3.0px 0.0px; line-height: 15.0px"><font face="Verdana" size="3" style="font: 11.0px Verdana"><b>Compatibility with emerging government and national standards</b>: Several government organizations, such as the United States Federal government, have mandated a transition to IPv6 for their internal systems; likewise, because of the short supply of IPv4 addresses, ISPs in various parts of the world—particularly Asia—are deploying native IPv6 support to their enterprises and consumers. By using IPv6, Windows Meeting Space can be deployed confidently with the knowledge that it will be compatible with these technology mandates.</font></li> </ul></div><div><br></div><div>Opiniones??</div><div><br></div><div>Saludos,</div><div>Nicolas.</div><div><br></div><div><br></div><div><br></div><div><br><div><div>On 15/04/2009, at 02:13 PM, Azael Fernandez Alcantara wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="margin-top: 0px;
