RFC3026:ENUM与IETF/ISOC的联络

MINIPCI 接口规范,包含物理,数据,等等内容-The Mini PCI Specification defines an alternate implementation for small form factor PCI cards referred to in this specification as a Mini PCI Card. This specification uses a qualified sub-set of the same signal protocol, electrical definitions, and configuration definitions as the PCI Local Bus Specification. Where this specification does not explicitly define PCI characteristics, the PCI Local Bus Specification governs.

Transporting DNP V3.00 over Local and Wide Area Network. 1 Overview 1.1 Purpose DNP V3.00 (hereafter referred to simply as DNP) was designed for serial point-to-point communication (e.g. RS-232) with limited support for half duplex serial networks (e.g. RS-485). In order for devices to exchange DNP messages in a local (LAN) and/or wide area network (WAN), one must either augment the protocol to support a network environment or use an existing network transport mechanism. This document takes the latter approach specifically, to define how to transport DNP traffic on the internet protocol suite. -Transporting DNP V3.00 over Local and Wide Area Network. 1 Overview 1.1 Purpose DNP V3.00 (hereafter referred to simply as DNP) was designed for serial point-to-point communication (e.g. RS-232) with limited support for half duplex serial networks (e.g. RS-485).
