Nowadays, companies need (large or small) some form of internet connection, but marketing jargon confusion can completely overwhelming. In general, how the Internet works, everything is the same. The main differences Fast Ethernet, Gigabit Ethernet and Metro Ethernet, for example, consists mainly in the number of channels, each of which can carry, and the bandwidth for the transmission of the frame (data).
Digital Subscriber Line (DSL) is the universal service from an ISP, and is based on traditional phone lines for data transmission. In general, DSL is mostly limited to private use because of its minimal bandwidth. A leased line T1 line has a bandwidth of about 1.544 Mbps T1 PRI line is based on the traditional T1 infrastructure, but provides digital access to public switched telephone networks (PSTN) to provide, and a T3 line is 44.736 Mbps dedicated line. Ethernet over copper, the process can take from 50 to 100 Mbps. To download and 2 to 10 Mbps for download, enough work for the use of bandwidth in a shared office Ethernet fiber connections were most commonly used as a backbone, but also recently introduced for the end user side.
Metro Ethernet (Metro Ethernet), a broader base, provides Internet connectivity to a large number of participants. According to the different possibilities to connect to the Multiprotocol Label Switching MPLS () uses the most. Inadvertently, finally using MPLS Virtual Private LAN Service (VPLS).
All these techniques and technologies have not overnight, it took a long time to take shape, they are today. In fact, every day the number of complete solutions for Internet connectivity. There is nothing that sounds better than it should, but it also leads many individuals and businesses to confusion, because all can not be tech savvy.
This is where companies a genuine consultation and know-how, some or all of these could lead to rushed backwards instead, triggering various obstacles and barriers that need. Although some users must also make the right choice in this regard, but the effects of their decisions. No gigantic scale as in the case of medium-sized establishments or large
Given all these factors, it is inevitable that business critical accuracy. In their choice of type of Metro Ethernet services they choose to serve their communication needs Although this is another important factor that must be considered the future compatibility of Internet access to the growing needs and the structure of a business.
