IP/MPLS Network

Market Trends

• IP/MPLS networks are becoming the key initiative
  of service providers in future planning driven by
  business and consumer demand for enriched
  applications-based services
• Providers are consolidating Legacy and IP
  services on the same IP/MPLS infrastructure
• Many large enterprises and smaller organizations
  are migrating their data, voice and video
  applications to a common converged IP platform

5
Open Networking Environment

• An open networking environment supporting
  any-to-any and end-to-end service is fundamental
  to the success of mass market applications such
  as Voice over IP, Content Distribution and global
  VPN for multinational corporations
• These services must extend beyond the provider
  single network.
• Today, a single operators network can provide
  performance guarantee, but has limited geographic
  reach
• The public Internet provides Global connectivity,
  but falls short of providing a robust environment
  for global VPNs, content delivery or other
  applications with more rigorous performance
  requirements

Inter-Carrier Connection

• The answer to delivering this new type of
  networks lies in
• extending public IP/MPLS networks beyond each
  providers
• footprint through commercially-oriented
  inter-carrier interfaces

IP/MPLS Beyond Boundaries

• Consumers and Businesses will pay for enriched
  communications that overcome their frustration
  with a best-effort Internet.
• Businesses seek their productivity and cost
  benefits of a transition of a private network to
  public IP network solutions
• In order to compete effectively for the resulting
  new revenues, carriers must also overcome several
  fundamental challenges
• Focus their capital and resources on their
  existing networks
• Economically difficult to justify an extensive
  network presence
• Difficult to compete with strong branded local or
  national networks
• Off-net facilities extensions are costly and Opex
  intensive
• Telecom business models require critical mass of
  users to leverage economies of scale and growth
  profits
• Maximal market opportunity is gained by extending
  services off-net Ex PSTN, The Internet
• Interconnecting to other carriers new revenues
  are gained by transporting and terminating
  traffic
• Redefining service definitions and business
  framework beyond best-effort environment

IP/MPLS Inter-Carrier Capability

• Internet Providers currently use peering
  arrangements to connect their IP networks, but
  these connections only provide best-effort
  connectivity
• The definition for an inter-carrier IP/MPLS
  solution will include the following
• Global Standard addressing
• Common signaling protocol
• Metering for settlement
• Security Protection across the interface
• Compliance to meet domestic and international
  regulations
• Commercially driven network-to-network
  transparency

Overall Architecture
The New Public Network

• Expected performance driven by the users
  application
• Appropriate levels of security, quality and
  bandwidth will be either reserved or negotiated
  through service controls and delivery frameworks
• Predictability throughout the network
• Assured delivery relies on a highly controllable
  robust MPLS foundation that supports dynamic
  network environment for all applications
• Realistic implementation for omnipresent
  communication
• Inter-Carrier MPLS interface must be leveraged
  to expand addressable markets.

A new form of Global Networks will emerge
overtime similar to todays PSTN and Internetand
yet built to deliver a very different set of
applications

Global Crossing IP Network

• IP deployed directly on DWDM backbone for
  improved throughput and rapid scalability
• Fully redundant IP network IP hubs
• Fully-meshed global MPLS network with over 10,000
  MPLS tunnels
