Cisco Multicast VPN Technology Helps NTT Communications Deliver
Video Services
Japanese Service Provider Reduces Cost, Simplifies Management
of Network Access
SAN JOSE, Calif., TOKYO, JAPAN - March 21, 2005 - 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.

implemented easily and at lower cost:
However there is a newer technology which has developed not very late ago. It's called VPN (Virtual Private Network) it's a wonderful way to connect through VoIP, fully guarding your concerns on breach of security. VPN forms a personal gateway between two users with the help of routers and forbids any attempts of intrusion. Although placing routers is an expensive affair altogether but many broadband service providers have begun offering a separate VPN servers to their routers.

Microsoft Cisco IP multicast is a mature technology that has been included
in the Cisco IOS Software since version 10.0, making it possible to
support multicast VPN without adding any new functions to the core
routing device. Because the user network interfaces for the
technology are the standard Protocol Independent Multicast (PIM)
and Internet Group Management Protocol (IGMP), it can be housed
without changing users' multicast environment configuration and it
has the advantage of not requiring the use of tunneling, such as
generic routing encapsulation (GRE) on the users' side for the
multicast. All IP multicast technology developed with Cisco IOS
Software can be applied at the VPN connection level, and it is
possible to provide additional value, such as the multicast
security redundancy and quality of service (QoS) provided by Cisco
IOS Software.
