Packet watermarks were introduced to address these issues in the early 2000s; but, Cisco and Juniper generally promoted the notion of "free" bandwidth and bandwidth allocation schemes limited to coarse estimates (MPLS, etc.). Packet watermarks also enable differential QoS at far higher efficiency in computational overhead and better management of "flow". The other push comes from search and poor notions of where the network (*your* network / infrastructure) starts. Innovation suffers when legacy models are not subject to "restart"!

The problem with the current network address approach is that it takes each packet at face value (This one says it came from google.com? Good enough for me!). The idea of integrating authentication is a real step forward, whether it is done in a content-centric approach or an overlay onto the current structure. This seems to be a clean-sheet-of-paper approach, which has technical advantages and huge logistical challenges. Step one: throw away all of your infrastructure. Step two: doesn't matter until you get people to do step one. Larry M.

One challenge of content-centric networks is that low quality information may be more difficult to avoid. The current network address based approach helps to identify trusted sources and avoid spam.

Content-centric networks should be a natural for any company to use for all their product design activities. The PARC announcement also strongly suggests the re-discovery of the use of hashed binary trees, which are the strongest data structures (read also of course files, networks, clouds, etc.), capable of organizing and providing immense amounts information, especially for hierarchical product and library design information. I believe you will find that NSA is also using this basic data and network paradigm for their huge huge collections of information. My own background here is that this is the approach we took at Honeywell Large Information Systems EDA hierarchical design data using what Honeywell called indexed-sequential files. We implemented a EDA database we called MUSER which was actively used by Honeywell / Bull from 1969 through 1997, and was only shut down due to the french Bull folks having to use some many off the shelf design tools. --Steve Grout

LATEST ARCHIVED BROADCAST
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.
