NTT Picks Cisco Mulicast VPN Tech

SAN JOSE, Calif. and TOKYO -- Cisco Systems® today announced that NTT Communications Corporation (NTT Com) has decided to use Cisco® multicast virtual private network (VPN) technology in the backbone network for its "Arcstar IP-VPN" service. Multicast technology will help NTT Com offer cost-effective video services and manage access restrictions to content.

In the past, highly secure and centrally managed multicasting required a significant burden to service providers because they need to restrict access to content based on the equipment and operations adopted by the customer. By using multicast VPN service, it is possible for NTT Com to easily place access restrictions on the network, which means the company can easily customize what content is available to each end user. Furthermore, customers already using NTT Com's Arcstar IP-VPN service are able to implement multicasting without purchasing new services or equipment. For this reason, the operating burden and costs can be reduced, making it possible for business and residential customers to easily and economically implement multicasting.
