Multi-Layer MPLS Traffic Engineering
多层次MPLS流量工程

This paper introduced the disadvantages of uni-layer.After explaining the characters a nd principles of MPLS which support MPLS traffic engineering, the paper discussed the multi-layer MPLS traffic engineering and gave out examples to illustrate. Then explained the differentias between uni-layer MPLS traffic engineering and m ulti-layer MPLS traffic engineering. Finally, we proposed the domain that we can continue study to end the article.
