Challenges for Submarine Cable Systems toward NGN & Global Cloud Computing
In view of the global network development toward Cloud Computing, there are still a lot of challenges remaining: “Transmission Delay”, “Traffic Throughput”, “End-to-end Path Provisioning”, “Bandwidth Adjustment” and “Network Connectivity with IP Network & Service Platform”. In addition, it has become imperative to develop ways to integrate the existing networks into the packet based networks in order to realize a reduction in OpEx, and also to provide a flexible and quick way to introduce new services. Furthermore, it is also necessary to find a way to coexist with non-packet traffic, taking into consideration that all traffic will not be completely migrated to packet based traffic.

The converged packet optical transport platform based on the OTN and MPLS-TP technologies is an optimum solution for submarine cable systems to resolve the current network issues. The technologies employed in the converged packet optical transport platform are ideal not only for high capacity transmission, but also for transport of both packet and non-packet
- traffic. By incorporating the protection schemes with high fault-tolerance
and integrating SLTE functionality, the converged packet optical transport platform can configure a submarine cable system on a single platform. It enables simpler network management, and the simplified network management by a single management system further contributes to OpEx
- reduction. In addition, the traffic engineering capabilities enable flexible
control of the network resources, and value-added services such as QoS (Quality of Service) can be introduced.

LSR Integration Realize the shortest path routing without going through POP. Minimize transmission delay. Reduce bandwidth of backhaul network. Improve connectivity with MPLS network. OSS/BSS Simplify O&M and Reduce OpEx. Realize On-demand & Rapid End-to-end Path Provisioning. Realize On-demand & Rapid Bandwidth Adjustment. Enable diverse international network services. IWOC Improve TCP traffic throughput degraded due to ultra long-haul transmission. Create new bandwidth services.
Due to the nature of submarine cable systems that provide Ultra long-haul transmission, a transmission delay is a serious problem. In addition, a transmission delay causes significant degradation of traffic throughput. This issue currently becomes concerns not only for system operators, but also for end users. LSR Integration and IWOC are considered as the solutions. Utilization of OSS/BSS enables simplification of O&M as well as reduction of
- OpEx. In addition, it will realize new services such as on-demand and rapid
