Businesses depend upon their networks as the lifeblood of day-to-day operations. Bottlenecks malaysia history data communication mean lost time and lost time translates setup streamyx connection a loss in revenue. It is essential for companies broadband solution provider stay up to date with the best technologies that keep the network performing at an optimum level.
Information sharing has permeated society at every level, simultaneously straining the backbones on which the global network was built. Understanding the latest innovations is key for any business looking to accelerate past the competition.
The explosive growth of voice and data transmission flowing over the Internet Protocol (IP) has been largely responsible for straining back-haul network bandwidth. Some ISPs are reporting that bandwidth demand on their backbone connections is doubling approximately every 8 to 14 months in response to ever-increasing Internet traffic.
The Internet backbone must further deal with the increasingly complex makeup of the traffic itself. Multiple data protocols must be transmitted, including circuit-based communications malaysia and brunei as fax or TDM voice, IP packets or even packet-switching protocols and frame relay.
Faced with these concerns, Internet carriers traditionally were forced to lay additional fiber optic cabling to accommodate additional demand for bandwidth. However, at a minimum starting cost of $70,000 USD per mile, the associated costs are streamyx lowyat in most situations except for the highest-level backbone connections.
Need always leads to innovation. The development of DWDM (Dense Wavelength Division Multiplexing) is a key innovation that allows for more bandwidth without installing additional, cost-prohibitive cabling. The concept is easy to understand: Increase the number of wavelengths that can be transmitted on a fiber. Fiber optic cabling uses lasers for transmission through the glass medium.
Previously, these transmissions were carried out at a single frequency. By simultaneously transmitting data at different frequencies or different light colors, the signal is multiplexed. This action effectively increases fiber optic cable capacity by a factor between 16 and 32.
Since the introduction of fiber optic cabling, SONET (Synchronous Optical Network) has been the standard communication protocol in North America. SONET works by streamyx broadband combo network signals and multiplexing them into a single wavelength to be transmitted over fiber. Counting on a single light wave to carry all the data drastically limits the capacity of the protocol.
SONET transports TDM data over the optical medium. Further inefficiency is created by current TDM (Time Division Multiplexing) technology. TDM was initially developed by phone companies to maximize the amount of voice data that can be transmitted over a medium.
TDM works by increasing capacity of the backbone link by collecting bits of raw data from multiple sources and multiplexing them at the higher transmission rate. TDM reserves time slots in the process to transmit the multiple sources in round-robin order. However, the proliferation of other data formats not based on circuits such as IP and cell-based transmissions forces TDM to deal with formats for which it was not tm streamyx email For example, Ethernet transmissions over SONET result in wasted bandwidth of up to 80% in a 10 Base-T connection.
TDM was never designed to handle anything other than voice data. Where SONET relies on TDM to transmit data for which it was not designed, drastic deficiencies occur.
Here are some key benefits of DWDM technology over SONET:
?Transparency - Operating at the primary layer of network architecture with raw data bits and streams, DWDM is able to support TDM and any other data format such as Ethernet, ATM, Fibre Channel or ESCON.
?Scalability - DWDM utilizes "dark fiber" or bandwidth otherwise wasted by inefficient transmission protocols like SONET for an instant boost.
?Dynamic provisioning - Eliminating time slots for data transmission allows for connections to be provided dynamically at a menara kuala lumpur higher rate. ?Reduced need for regenerators - Transmitting multiple signals over a single fiber decreases the need for additional expensive equipment otherwise needed to re-amplify and de-multiplex signals over multiple fibers.
Four important questions readers should ask themselves:
1. Are you experiencing bottlenecks in your fiber optic network?
2. Does your network continuously transmit multiple data formats?
3. Are you looking for a simple, yet highly effective technology to gain a competitive edge?
4. What is keeping your business from transitioning to DWDM on the back-haul networks across the enterprise? DWDM technology dramatically increases transmission capacity while simplifying scalability concerns at the broadband isp providers time. The primary requirement is installing higher transmission capacity at one end of the fiber optic cabling.
DWDM drastically reduces signal congestion created by amplifiers and regenerators. High-capacity network transmissions around the business can be conducted without some of this equipment when DWDM is implemented.
DWDM is a smart strategy for a highly optimized optical network. Since the sharing of information is the lifeblood of any business, the network must have the highest level of availability, and downtime must be kept to an absolute minimum.
Backups performed in real-time and decentralized processing are essential to keeping mission-critical applications online, as are parallel processing and a comprehensive disaster bangsar kl plan. The common theme among these best practices is the requirement for a network of the highest quality, efficiency and reliability.
Dense Wavelength Division Multiplexing is a smart alternative to traditional Time Division Multiplexing. Know what your options are now and consider the benefits as you expand business operations.
