Error Correction Control for Next-Generation Solid State Drives [published: July 2014]

Abstract:This white paper discusses Error Correction Codes (ECCs) for Next-Generation Solid State Drives (SSDs). It describes the need to transition from classical ECCs to new versions such as Low-Density Parity-Check (LDPC) codes. It then presents an overview of LDPC codes and shows why they are a popular choice for next-generation SSDs. The white paper concludes with some real-world examples of how LDPC codes can be used to improve the performance of next-generation SSDs.

Programmable Data Plane Extends OpenFlow to Carrier Applications [published: Apr 2014]

Abstract: Data networks continue to be challenged by the exponential increase in the number of
connected devices (the “internet of things”) and traffic volume, which is expected to grow by an
order of magnitude over the next decade. The cloud model creates uncertain and very dynamic
traffic patterns. As a result, the network management required to ensure adequate quality of
service becomes prohibitively complex and in many cases inefficient, requiring expensive
network over-provisioning.
