【Abstract】 Multiprotocol label switching (MPLS) adopting integrated model, not only solved efficiently the problems existing in the current Internet, but also supported many new functions. The paper discussed the output buffered architecture’s advantages of the ATM LSR cable VC merging aimed at network scalability, proposed the traffic and queuing model of resemble buffers and output buffer in the output module based on the architecture, deduced the closed expressions of important performance parameters, and provided a feasible arithmetic for implementing the band allocation and management and performance supervision under the condition of VC merging.更多还原
