Cross-layer Stack Architecture

Cross-layer Stack Architecture

◮ Layered design

◮ Self-containment + Abstraction ◮ Independent layers + Inter-layer relationships ◮ Stacked in an order

◮ Cross-layer architecture as an inter-layer relationship concept

◮ Comprehensive information through overall architecture ◮ Different directions through different modules
