High speed bulk data transfer using the SSH protocol

ABSTRACT

SSH is a highly successful multipurpose protocol used for both interactive shells and transport layer mechanisms. However, a design choice in most implementations of SSH reduces its functionality as bulk data transport tool in high performance network environments. This paper will discuss the nature of this limitation, the functional barriers it imposes, a method by which it can be remedied, and introduces a high performance implementation based on the industry standard, OpenSSH. Additionally, the authors will introduce a method by which performance on multi-core systems is improved through the use of cipher multi-threading.
