All, In your humble opinion, which transmission method is more efficient, packet or cell? Granted a cell is a fixed length packet and an IP packet is variable length....would this necessarily only relate to a specific protocol, namely, cell in ATM, and IP in Ethernet or other types of domains....feedback highly welcomed. Trying to make a decision on the transport mode for cost, delay, jitter, ROI, etcetera.
