New Challenges to Network Management
Network management is vital to the functioning, configuration, service differentiation, and accounting of large networks
Traditional telco networks are over-managed which leads to unnecessary complexity and inefficiency
Internets tend to be under-managed
We need new solution where the management of core networks and access networks are separated
- Customer-specific service differentiation and billing are done at the access points, leading to scalability
- The core network is managed statistically, leading to great efficiency
Security of network management is key to the security of the entire network => strong security is needed for network management protocols and applications
