| Abstract: | Multi-granularity switching is one of the key technologies for next generation Optical Network- Automatic Switched Transport Network It can reduce network nodes and equipment cost. In this article, the advantages of MGS are given. Quantitative analysis is given by accounting and comparing the port count to prove that the constitution of OXC can be simplified by introducing MGS. Multi-granularity hierarchical routing, multi-granularity signaling mechanism and link manager technology are presented, and the influences of system application related to survivabil-ity and traffic engineering of ASON by introducing MGS are discussed. |
