This document specifies a set of TCP extensions to improve performance over paths with a large bandwidth * delay product and to provide reliable operation over very high-speed paths. It defines the TCP Window Scale (WS) option and the TCP Timestamps (TS)

This memo discusses methods for efficiently computing the Internet checksum that is used by the standard Internet protocols IP, UDP, and TCP.An efficient checksum implementation is critical to good performance. As advances in implementation techniques streamline the rest of the protocol processing, the checksum computation becomes one of the limiting factors on TCP performance, for example. It is usually approapriate to carefully hand-craft the checksum routine, exploiting every machine-dependent trick possible; a fraction of a microsecond per TCP data byte can add up to significant CPU time savings overall.

This article explores Marx’s contention that the achievement of full personhood and, not just consequently, but simultaneously, of genuine intersubjectivity depends upon the attainment of recognition for one’s place in the social division of labour, recognition which is systematically denied to some individuals and groups of individuals through the capitalist organization of production and exchange. This reading is then employed in a critique of Axel Honneth’s theory of recognition which, it is argued, cannot account for the systematic obstacles faced by some struggles for recognition.
