The ISODE software (pronounced eye-soo-dee-eee), more formally the ''ISO Development Environment'', was an implementation of the OSI upper layer protocols, from transport layer to application layer, which was used in the Internet research community to experiment with implementation and deployment of OSI during the late 1980s and early 1990s. The ISODE software was initially a public domain / open source implementation, led by Marshall Rose. Following version 6.0, Marshall handed the lead over to Colin Robbins and Julian Onions, who coordinated the 7.0 and 8.0 releases. Version 8.0 was the final public domain release, made on June 19, 1992. The Open Source version is still available, even if only for historic interest. The software was ported to a wide set of Unix and Linux variants.〔(【引用サイトリンク】url=http://ftp.sunet.se/pub/network/isode/isode-ports.txt )〕 == ISODE Stack == The ISODE stack was an implementation of layers 3 to 6 of the OSI model. While the ISODE implementation could be configured to use one of several X.25 (CONS) or connectionless lower layer protocols, many ISODE deployments were based on RFC1006,〔(【引用サイトリンク】url=http://tools.ietf.org/html/rfc1006 )〕 the implementation of OSI transport protocol TP0 as a layer atop TCP, in order to use IP-based networks which were becoming increasingly common. The stack also implemented an ASN.1 compiler. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ISO Development Environment」の詳細全文を読む スポンサード リンク
