NKN Design and Architecture
The main design consideration for NKN was to create an infrastructure that can scale and adapt to future requirements. NKN design philosophy is to Encourage, Enable, Enrich and Empower the user community to test and implement innovative ideas without any restriction from the network technology and its administration. Based on that philosophy, as a next generation network, NKN will cater to the following requirements:
Network design -
NKN design follows all the current standards to permit seamless inter-operability amongst technologies and seamless integration amongst different original equipment manufacturers.
Security requirements -
With the growing number of incidences reported by CERT and the increasing challenges posed by innovations in convergence, keeping the network alive can be possible only with very stringent security measures designed, implemented and deployed. Any specific requirement for limiting access to services should be deliverable as part of a security policy. The Central Command Control created to react to such situations should address till-date and forecasted attacks.
Service requirements -
These requirements are essential for transparent delivery of services based on either heritage (as in telephony) or the general requirements for a particular service. These requirements might differ between service providers, and possibly even between different tiers of a similar service.
Network requirements -
These requirements are network-specific and can be tied to specific services, specific delivery mechanism (client could be variety of devices like PC/ PDA/ any other device) and access mechanisms like (intranet / Internet). The design will cater to the overall performance goal of the NKN infrastructure. Operational requirements - The NKN is designed to cater to the requirements of tracking, troubleshooting, health monitoring, and proactive performance monitoring. With the converged network it becomes more important to proactively monitor the network for impending issues.
