This tutorial provides an overview of ADSL technology and focuses on the physical layer as defined in ANSI T1.413-1998. From the introduction: "The demand for high-speed data networks in the "last mile" has driven the need for robust, interoperable, and easy to use multi-vendor Digital Subscriber Line (DSL) access solutions. DSL collectively refers to a group of technologies that utilize the unused bandwidth in the existing copper access network to deliver high-speed data services from the distribution center, or central office, to the end user. DSL technology is attractive because it requires little to no upgrading of the existing copper infrastructure that connects nearly all populated locations in the world. In addition, DSL is inherently secure due to its point-to-point nature."

An overview of ADSL systems that includes network architecture, protocol architecture, typical ADSL implementations, RFC1483 bridging, PPP over ATM over ADSL, and PPP over Ethernet over ADSL.

This presentation provides an overview the ITU-T G.994.1 (G.hs) Handshaking Procedures for Digital Subscriber Line Transceivers standard.

The Extended Sockets API (ES-API) is a specification published by the Open Group that defines extensions to the traditional socket API in order to provide asynchronous I/O and also memory registration for Remote Direct Memory Access (RDMA). These two major new features enable programmers to take advantage of today's multi-core processors and RDMA network hardware, such as InfiniBand, iWARP and RoCE interfaces, in a convenient yet efficient manner.
