Ethernet is the dominating enterprise data networking protocol in the LAN environment and it is ubiquitous for IT managers and LAN users. However, cooperate communication requirement has changed over the years. Enterprises used to manage their own local secured LAN without much connectivity requirement beyond their local corporate campuses. Today, inter-working with branch offices, outside customers, access to the internet and storage networking for disaster recovery has become more common. Traditionally, this is achieved using narrowband and yet expensive private line services at T1, T3, or via FR/ATM fractional T1, T1, n xT1, T3 data services.
