Applications Network Performance



Applications requirements are drivers for bandwidth needs
DWDM delivers up to 100 Gbps
SONET framing delivers up to 40 Gbps
TCP/IP delivers about 15 Gbps
Site firewalls deliver about 7 Gbps to an application
But high-end applications require 40+ Gbps, e.g.:
– Terascale Supernova Initiative: Terabyte in days
– High Energy Physics: Terabyte data transfers

Therefore, consider optical networking options to:
– Bypass firewalls
– Carry non-IP frames (e.g., Fiber Channel over SONET)
