This paper proposes a novel adaptive algorithm based on a new soft-regulator (---) for concurrent multimedia flows at end hosts. Our algorithm has the following features: (1) does requires the support of the network layers (routers and switches); (2) is scalable as it can be installed into any intermediated nodes for the delay control; (3) uses network resource efficiently, in particular, when the bandwidth of network is very limited. Performance experimental data have shown that (---) and related algorithm are efficient and applicable as compared with network layer solutions.
