Physical Layer
The OSI, or Open System Interconnection, model defines a networking framework for implementing protocols in seven layers. Control is passed from one layer to the next, starting at the application layer in one station, proceeding to the bottom layer, over the channel to the next station and back up the hierarchy.
Layer 1 of the OSI model is the Physical Layer.
The Controller Area Network (CAN) protocol defines the data link layer and part of the physical layer in the OSI model, which consists of seven layers. The International Standards Organization (ISO) defined a standard, which incorporates the CAN specifications as well as a part of physical layer: the physical signaling, which comprises bit encoding and decoding (Non-Return-to-Zero, NRZ) as well as bit timing and synchronization.

If Wi-Fi is ever going to challenge Ethernet, it will need to improve its performance, both in terms of speed and range. The good news is that the IEEE's member vendors are working on ways to do this, developing 802.11n, a fourth Physical layer for Wi-Fi aimed at increasing its maximum real TCP/IP throughput to 100Mbits/sec or more. The bad news is that products based on 802.11n are still about three years away. Draft proposals are due to be published this month, with the serious horse-trading beginning in September.

Vitesse HOVCATe Mappers Provide Industry's Most Comprehensive Set of Features for Architects of Metro Ethernet Equipment
Vitesse Semiconductor Corporation (NASDAQ:VTSS) continues to drive innovation in the Metro Ethernet equipment market with its most recent additions to its VersaCAT(TM) Ethernet-over-SONET product family, HOVCAT48e and HOVCAT192e. The HOVCATe(TM) (High Order Virtual Concatenation) devices map traffic at OC-48/2.5 Gbps and OC-192/10 Gbps and provide the most comprehensive set of features on the market today. These devices enable carriers to utilize existing SONET/SDH networks to efficiently and cost-effectively transport data services with new or existing platforms. The mappers support GFP, LCAS, and Virtual Concatenation for use in Multi-Service-Provisioning Platforms (MSPPs), SONET/SDH Add/Drop multiplexers, and Resilient Packet Ring (RPR) applications.

Re: SONET Is Dead
From Reader Comments
I agree, long gone are the days that when a 20Km piece of dark fiber is purchased everyone bricks themselves. We no longer need to purchase expensive SDH/SONET tin to spit a packet further than across the corridor.
Despite this, and speaking as a 'nethead' I can't help but cough when everyone starts shouting for the death of all things telco. It's just not going to happen any time soon.
IP kit is edging it's way in from the outside inwards, I agree! But an absolute death of SONET? Grow up.
Seasons change my friends, and as they do new technologies shall emerge and mature. However, not only are 90% of ethernet based l2 mpls vpns carried using IPoverSDH, I am not seeing options on GBICs suitable for transcontinental interlinks.
Telco equipment has had eons to mature, and provides SLA's that IP equipment isn't even close to meeting.
I agree, Ethernet is kicking butt, and shall not reach it's zenith for quite some time. I disagree that SONET is dead.
I agree with this commenter. I think SONET will be around for many years to come.

The day-long session, moderated by Heavy Reading analyst Simon Stanley, focused on the semiconductors, optical modules, and network processors being targeted at 10-Gbit/s Ethernet.

OSI History
The OSI (open Systems interconnection) model was developed by the International Standards Organization (ISO) in 1984 in an attempt to provide some standard to the way networking should work. It is a theoretical layered model in which the notion of networking is divided into several layers, each of which define specific functions and features. However it must be noted that this model only represents a general guideline for developing usable network interfaces and protocols. Sometimes it may become very difficult to distinguish between each layer as some systems do not rigorously adhere to the model. Despite all this, however the OSI model has earned the honour of being "the model" upon which all good network protocols are based.

The history of the development of the OSI model is, for some reason, a little-known story.

This group was chartered, within Honeywell, with advanced product planning and with the design and development of prototype systems.

Lambda Optical uses microelectrical mechanical systems (MEMS) to build all-optical switches for metro and regional networks. It also sells a reconfigurable optical add/drop multiplexer (ROADM) and a remote-access device.
I like to study about telecommunications equipment. It either works or it doesn't. Unless it works sometimes and other times it doesn't. Or maybe it works good in the lab but not in the field. Some things only look good on paper.
Founded in 2003 from the intellectual property of folded start-up Firstwave Secure Intelligent Optical Networks, Lambda Optical announced a $14-million series-B funding round in April, bringing the company’s total funding to $24 million.
