Crossing the IPv6 Chasm: The Teleglobe Case Study

Teleglobe as global Internet Service Provider
Teleglobe is a Canadian based global international carrier and operates a worldwide voice and data network. It has capacity in about 100 international cables and recently acquired Princeton, NJ-based ITXC, the world's major VoIP wholesale carrier.
Teleglobe operates a global IP network under one Autonomous System (AS6453), and has more than 40 major international POP locations in North America, Europe, Asia/Pacific and the Middle East. Backbone interconnectivity is based on multiple OC-48s and OC-192s. It is a Tier 1 network peering with all other Tier 1 carriers at over 70 public peering points. Teleglobe operates as a wholesaler and provides Internet access to carriers and ISPs in 93 countries, ranging from Algeria to Zimbabwe. Teleglobe operates a Cisco-powered network and ...

IPv6 Secure Proxy Appliance, Enforcing Information Security

Address expansion is probably the most well known feature of IPv6. The problem of IPv4 address space shortage, however, is more critical to the private sectors, and is less applicable to the networks under the control of the US government agencies and the various sectors within the US armed forces. The statement that IPv6 brings more security related values to network infrastructures and communications also needs closer examination. For example, the end-to-end secure communication model is a reality in IPv4 when globally unique address assignments are possible. Many of the security problems that plague IPv4 operations remain in the IPv6 realm. On the other hand, many of the new features in IPv6 introduce additional threats and require much more thoroughful analysis and demand more sophisticated solutions. Clearly, those other features of IPv6 such as the improved Quality of Service as discussed by Dr. Lawrence Roberts, IPv6 Mobility, reduction in the complexity of network management and the routing infrastructures, are just some examples of benefits from IPv6, which are important to the Department of Homeland Security (DHS), and to DoD in aiding its construction of the Global Information Grid (GIG). Mobility and secure communication over various types of wireless infrastructures are critical to ...

IPv6 and Location Based Gaming

Location Based Gaming (LBG) is a specialized form of videogaming that takes advantage of the fact that the network knows where each user is. This allows the game landscape to incorporate real world elements of the location that the players are located in. In a city, for instance, an LBG can interleave the player's ordinary experience of the city with the extraordinary experience of the game. Location based gaming is very new - so new that no major companies have established dominance in this market yet - but is the most dynamic segment of the mobile games market, which in turn is the fastest growing segment of the huge videogame market.
The fidelity and richness of content of such games is at present relatively low. Most present LBGs such as BotFighters in Sweden are played with cellphones - the players know where they are within a few hundred feet ...


"The Spirent tools greatly enhanced our testing capabilities and enabled my test team to test performance, conformance and mobility." - Major Roswell V. Dixon, Joint Interoperability Testing Command (JITC) tactical data systems/IPv6 test director.
Spirent helps test deployment of next-generation Internet network
Today's Internet has run on Internet Protocol version 4 (IPv4) for over 20 years. Because its planners never expected its popularity, today there's a growing shortage of IP network addresses-a problem that is only intensifying with the proliferation of Internet-enabled devices. Fortunately, the next-generation Internet protocol, IPv6, not only solves this problem but also improves network routing and configuration processes. Designed by the Internet Engineering Task Force (IETF), IPv6 is expected to gradually replace IPv4.

OSPF and IPv6 White Paper

OSPF has been adapted to support IPv6 in RFC 2740 (OSPFv3). All fundamental mechanisms of OSPF remain unchanged, such as flooding, areas, DR election, SPF route calculation, etc. However, some changes are needed to accommodate IPv6:
All addressing semantics were removed from OSPF packet and LSA headers.
New LSAs have been created to carry new IPv6 addresses and prefixes.
OSPFv3 now runs on a per-link basis, instead of on a per-IP-subnet basis.
The flooding scope for LSAs has been generalized.
Authentication has been removed from the OSPF protocol itself, which relies instead on IPv6's Authentication Header and Encapsulating Security Payload
