  8. Another disadvantage for sra algorithm is that it cannot avoid the instance that some traffic classes may be jammed abruptly, but other traffic classes have free resources. the thesis presents an algorithm, called peb _ esra ( pre - estimation and borrow based esra algorithm ), which permits borrowing resources among traffic classes. to some extent, it solves the short - term unbalance of resources allocation

    針對sra演算法無法解決可能出現的某業務類突發性擁塞，而其他業務類尚有空閑資源的情況，論文在繼承peesra演算法的基礎上，提出允許業務類之間資源借用的pebesra （ pre - estimationandborrowbasedesraalgorithm ）演算法，該演算法在一定程度上緩解了由於業務流突發性擁塞造成的資源配置短期失衡問題。
