Transparent LAN Service Over Cable
Transparent LAN Service over Cable This document describes the Transparent LAN Service (TLS) over Cable feature, which enhances existing Wide Area Network (WAN) support to provide more flexible Managed Access for multiple Internet service provider (ISP) support over a hybrid fiber-coaxial (HFC) cable network. This feature allows service providers to create a Layer 2 tunnel by mapping an upstream service identifier (SID) to an IEEE 802.1Q Virtual Local Area Network (VLAN).

Introduction to Spanning Tree Protocol By George Thomas, Contemporary Controls Introduction powered and its memory cleared (Bridge 2 will be added later). In an industrial automation application that relies heavily Station 1 sends a message to on the health of the Ethernet network that attaches all the station 11 followed by Station 2 controllers and computers together, a concern exists about sending a message to Station 11. what would happen if the network fails? Since cable failure is These messages will traverse the the most likely mishap, cable redundancy is suggested by bridge from one LAN to the configuring the network in either a ring or by carrying parallel other. This process is called branches. If one of the segments is lost, then communication “relaying” or “forwarding.” The will continue down a parallel path or around the unbroken database in the bridge will note portion of the ring. The problem with these approaches is the source addresses of Stations that Ethernet supports neither of these topologies without 1 and 2 as arriving on Port A. This special equipment. However, this issue is addressed in an process is called “learning.” When IEEE standard numbered 802.1D that covers bridges, and in Station 11 responds to either this standard the concept of the Spanning Tree Protocol Station 1 or 2, the database will (STP) is introduced. note that Station 11 is on Port B.

IEEE Standard for Ethernet IEEE Computer Society Sponsored by the LAN/MAN Standards Committee IEEE 3 Park Avenue IEEE Std 802.3™-2012 New York, NY 10016-5997 (Revision of USA IEEE Std 802.3-2008) 28 December 2012 IEEE Std 802.3™-2012 (Revision of IEEE Std 802.3-2008) IEEE Standard for Ethernet Sponsor LAN/MAN Standards Committee of the IEEE Computer Society Approved 30 August 2012 IEEE-SA Standard Board Abstract: Ethernet local area network operation is specified for selected speeds of operation from 1 Mb/s to 100 Gb/s using a common media access control (MAC) specification and management information base (MIB). The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) allow use of selected Physical Layer devices (PHY) for operation over coaxial, twisted-pair or fiber optic cables. System considerations for multisegment shared access networks describe the use of Repeaters that are defined for operational speeds up to 1000 Mb/s. Local Area Network (LAN) operation is supported at all speeds. Other specified capabilities include various PHY types for access networks, PHYs suitable for metropolitan area network applications, and the provision of power over selected twisted-pair PHY types.

Comparison of the IEEE 802.11, 802.15.1, 802.15.4 and 802.15.6 Wireless Standards
Comparison of the IEEE 802.11, 802.15.1, 802.15.4 and 802.15.6 wireless standards Jan Magne Tjensvold∗ September 18, 2007 1 Introduction This paper contains a comparison of some of the wireless standards authored by the Institute of Electrical and Electronics Engineers (IEEE) [1]. It explain some of the differences and similarities between the IEEE 802.11, 802.15.1, 802.15.4 and 802.15.6 wireless standards with an emphasis on the physical layer. 2 Wireless standards The wireless standards that we will investigate in this paper is only a selec- tion from all the standards available. These explanations are not meant to be exhaustive. 2.1 IEEE 802.11 - WLAN/Wi-Fi Wireless LAN (WLAN, also known as Wi-Fi) is a set of low tier, terrestrial, net- work technologies for data communication. The WLAN standards operates on the 2.4 GHz and 5 GHz Industrial, Science and Medical (ISM) frequency bands. It is specified by the IEEE 802.11 standard [2] and it comes in many different variations like IEEE 802.11a/b/g/n. The application of WLAN has been most visible in the consumer market where most portable computers support at least one of the variations. 2.2 IEEE 802.15.1 - Bluetooth The IEEE 802.15.1 standard [3] is the basis for the Bluetooth wireless communi- cation technology. Bluetooth is a low tier, ad hoc, terrestrial, wireless standard for short range communication. It is designed for small and low cost devices with low power consumption. The technology operates with three different classes of devices: Class 1, class 2 and class 3 where the range is about 100 meters, 10 meters and 1 meter respectively. -
