Comparing DSL, Leased Line, and Ethernet Circuits
When choosing a dedicated Internet access solution, companies are fortunate to have a wide range of options. Of course, each potential service presents its own specific technical challenges, key features and costs. As in many other areas of the information technology sector, traditional high-priced dedicated Internet access services have recently been severely challenged by low-cost, alternative technology innovation challenges in the UK market
Business Connectivity For many years Is a dedicated leasing line. A leased line (also known as E1, E3, Frame Relay, or OC line) is a permanent connection established between two different geographic points, such as two offices in the same company, or banks and remote financial institutions. The connection is not shared with any other users on the carrier & apos; s network, and thus it ensures stable bandwidth and excellent data security. This is an "always on" recommendation, one of the most reliable ways for businesses to transfer data or access the Internet. Leased lines can be configured to handle a wide variety of transmission speeds, typically providing superior support and service level agreements (SLAs) from providers. Leased lines can also be part of a WAN access solution that allows a local area network (LAN) to connect to other LANs and the Internet.
Unfortunately, the costs associated with leased lines are some of the most expensive in the industry. Installation time, installation costs, and maintenance and access charges imposed on line users can be daunting for many small businesses. The distance between the service, the provider, and the sites to be linked together also plays an important role in increasing the price of the leased line.
Digital subscriber lines (also known as DSL, ADSL, SDSL and ADSL Max) have been widely used and have long been avoided by companies seeking fast and reliable Internet access and data transmission. Originally targeted at consumer technology, DSL is based on switched data connection technology, which shares its bandwidth with other customers accessing the provider's network. Bind ADSL, however, works with multiple DSL lines in order to address many of the traffic congestion issues that are typically associated with this type of connection. Securing ADSL now provides the robust SLA required by the business, as well as excellent transmission speed. Installation is also faster and more flexible than leased lines. In addition, the cost is significantly reduced compared to standard leased lines. The recent infrastructure upgrades due to local loop unbinding (LLU) and the emergence of next-generation ADSL services, such as Annex M DSL, mean that bound DSLs will continue to improve in terms of bandwidth and availability.
Ethernet circuits are another cheaper option for those looking for high-bandwidth enterprise connectivity solutions. These virtual private networks (VPNs) are built from point-to-point Ethernet links at the city, regional, or national scale. The main advantage of VPNs is that they enable the company to provide the same level of broadband connectivity to many of the necessary offices and teleworkers and provide access to geographically specific resources from anywhere within the network, including Internet access. The bandwidth of this type of connection can be expanded to a very high level, and emulates the LAN in terms of functionality. A single connection point design also reduces connection and installation costs.
