Technique in which information from multiple channels can be allocated bandwidth on a single wire based on preassigned time slots. Bandwidth is allocated to each channel regardless of whether the station has data to transmit.
Interfaces that can recognize time slots and can forward data based on the data's time slot in a repeating cycle. This is typical of interfaces on digital cross-connects, SONET ADMs, and SONET cross-connects.
A mechanism to prevent loops in IP networks. The TTL field gets decremented every time a packet traverses a router. When TTL reaches 0, the packet can no longer be forwarded.
