Overview

The Subtree Routing Algorithm reduces blocking probability in multicast services, highlighting new strategies for spectrum resource management.

Key Points

  • The Subtree Routing Algorithm significantly improves multicast service request success rates through adaptive modulation.
  • Spectrum Resource Allocation improves efficiency by utilizing idle spectrum fragments and reducing fragmentation.
  • An integer linear programming model enhances network operators' ability to manage spectrum resources effectively.
  • Simulations show a 4.61% reduction in service blocking compared to traditional multicast algorithms, demonstrating practical significance.
