Introduction to Port Extension [pdf] - Cisco →
Abstract–Data centers today are
experiencing a rapid proliferation of switches
as a direct result of the deployment of highdensity
server platforms. Given the layered
switching architecture found in today’s data
centers, many of the switches are performing
a simple aggregation function; that is, the
majority of traffic is moving between
downlinks and uplinks. However, despite this
simple...

An integrated... →
Abstract—This paper describes Open Service Framework, a framework for enabling policy based flow steering and service load balancing capabilities in Layer 2/3/4 Ethernet switches. These software enhancements enable an Ethernet switch to steer packets based on user specified rules that consist of fields from the packet header and the ingress port. Additionally, the switch can load balance...

Addressing the Scalability of Ethernet with MOOSE... →
Abstract—Ethernet does not scale well to large networks. The flat MAC address space, whilst having obvious benefits for the user and administrator, is the primary cause of this poor scalability; other recent efforts to improve upon
Ethernet’s scalability have addressed symptoms, rather
than this underlying cause. In this paper we present
MOOSE, Multi-level Origin-Organised Scalable Ethernet,...

portfolio vs go-to-market
[Context: technology services business.]
The portfolio is composed of service offerings. Who delivers the services and how is highly variable, but it only matters that they can be delivered. In general, there’s a 1-to-1 between the services in the portfolio and those sold in the marketplace. That which is marketed is a discrete element in the portfolio.
Marketing messages come and go....

[Originally posted august 2008 to my old blog. ”Very Smart People” are just folks who can get things done, cut through the morass of bureaucracy, don’t work with blinders on, etc.]
People vary.
The bigger the organization, the greater the variance. You can try to build a company of only Very Smart People. But beyond some size, there’s no way. People vary.
