Net processors take fresh twists at N+I Product News 5/12/2000 Post a comment The legacy of the first wave of network processors began to unfold at the Networld+Interop show this week, as chip suppliers made their play to collapse more networking functions into silicon. Potentially, more and more of the jobs of a traditional switch, down to the esoteric processing functions handled by software, could become the domain of merchant silicon and might eventually become commodities.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
