| () |
| Abstract: |
| This paper introduces the design of a PoS data switch chip in the MSTP on SDH to supply the flexible data services in the transport and access equipment. The structure of the chip is based on a shared-memory switch structure, and an advanced pipeline technology is used to improve the switch capacity of the chip. This chip provides QoS guarantee and implements multicast capacity, and it can be used in the SDH transport and access equipment. It provides a simple and high-level efficient solution for the transportation of data services on SDH. |
