Lanza(Mayan) says, ―Traffic races over gigabit networks inside office buildings and within the Internet core, but when it travels between them it has to squeeze through a copper line-and that line is turtle-slow.
Young(Yipes) says, ―Your data leaves your office going nice and fast, hits the local phone company and turns into a snail, then takes off again when it reaches the backbone.until it hits the next phone company.

?.적합치않다.!
1)비효율적이다: Bursty data traffic을TDM방식으로서비스하는것은대역폭의낭비를가지고온다.
2)고가이다: TDM circuit을독점하며다른사용자의트래픽과통계적다중화가되지않으므로! 따라서링크대역폭당가용사용자수가적다. (T1~200만원/월, T3~5,000만원/월)
3)Ethernet 계위와SONET/SDH계위가맞지않는다: 10Mbps 전용선을원하는경우45Mbps T3 line을써야한다.

Worldwide Ethernet MAN Revenue by Region,
2001-2005
The Ethernet MAN Opportunity,
Gartner Dataquest, July 2001
Analysts at Gartner, Inc. recently projected that Ethernet MAN revenues will approach $50 billion worldwide by 2005, when more than 20 percent of mid-and large-sized businesses are likely to have Ethernet MAN or wide area network (WAN) connectivity. \"Ethernet is poised to do to metropolitan area networks (MANs) what it did to LANs in the 1990s: Ethernet-based MANs have the potential to overcome high-cost extra-office connectivity bottlenecks,\" according to the Gartner report

IEEE 802.17 RPRWG(dec. 2000), 표준화완료: 2003 Q1
Resilient Packet Ring Access Protocol for use in LAN, MAN and WAN for transfer data packets at rates scalable to many gigabits per second.
RPR MAC over Ethernet phy, SONET, WDM
Motivation
Ethernet : Restoration, No BW allocation for nodes on the Ring
SONET: Static point.to-point circuit between ring nodes ~ inefficiency, High-cost
