N2 - In this paper, novel Cross-layer Dynamic Bandwidth Allocation Algorithm Based on Convex Optimization Theory(CO-CDBA) in Digital Video Broadcast-Return Channel via Satellite system is proposed. A novel utility function by taking application layer, Data Link Layer and physical layer(PHY) parameters into account is established. The Dynamic Bandwidth Allocation(DBA) problem is converted to a convex optimization problem with constraints, which can be solved by using a fast interval iterative algorithm. The allocation result, utility value, users' fairness performance and allocation procedure based on CO-CDBA are simulated. Results show that CO-CDBA can reduce computational complexity and efficiently allocate bandwidth for each user. Fairness and utility are significantly improved compared with Max-Min and water-filling model.
