In the proposed flow control method for abr service in atm networks , by introduction of delay factors , the cell transmission rate for abr traffic with different rtd are adjusted differently when the surplus bandwidth varies , and the rate variation amplitude for the short rtd traffic will be enlargeed while one for the long rtd traffic will be lessened , compared with erica 改進的erica算法加入時延因子,使在連接中具有不同時延的用戶在剩余帶寬變化時,速率的調(diào)整具有不同反應(yīng),時延大的反應(yīng)較遲鈍,時延小的反應(yīng)較敏感。改進算法使得小時延信源能更快的適應(yīng)帶寬的變化,緩解了由于大時延信源速率調(diào)整的滯后而無法及時解除擁塞的現(xiàn)象。
