摘要內容：
One of the key elements in building a TDM (time division multiplexed) switch is the time-slot-interchange (TSI). Given the current optical switching and buffer technologies, TSI-based TDM architectures have many implementation drawbacks, including severe signal attenuation. Some references showed that some space-time equivalence diagrams can be converted into a delay-unit-based (TSI-free) TDM. This type of architectures is attractive for optical TDM switches. But the techniques discussed before are for rearrangeable switches. Many applications require nonblocking switches where adding a new connection (or a flow) will not cause rearrangement of existing connections. In this talk, I will present the design principle for building strictly nonblocking delay-unit-based (TSI-free) optical TDM switches.
