최근의 Metro optical networking분야의 동향과 기술을 정리한 자료입니다. 내용은 3 part로 나누어져 있으며 Metro가 각광 받는 이유를 기술적인 측면, 시장 조사기관의 메트로에 대한 Market estimation, 인수합병 동향, VC의 투자 동향들을 살려보고, Metro의 병목을 해소하기 위해 제시되고 있는 기술들에 대해 살펴봅니다. 이 기술들은 크게 LAN에서 사용되던 Ethernet에 새로운 기능을 추가하여 Metro로 나가자는 Metro Optical Ethernet, WAN에서 적용되던 DWDM을 Metro 환경에 맞게 채널수를 줄이고 다양한 인터페이스를 갖도록 변경한 Metro DWDM, 그리고 기존의 Metro 망에 구축되어 있는 SONET의 기능을 Data traffic을 효율적으로 수용할 수 있도록 개량한 Next-Generation SONET으로 나눌 수 있습니다. 이에 관해 알아보고 세번째 Part에서는 Metro Optical Ethernet에 관해 자세히 살펴보겠습니다. 10/25/2001: Presentation for Dreamline 10/31/2001: Presentation for Seminar on Optical network for Metropolitan Area 11/05/2001: Presentation for SoftBank

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.

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

RPR (Resilient Packet Ring)

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

싸다!

Ethernet Switch 가격

.전세계LAN port의94%가Ethernet

.대량생산으로인한부품, 칩가격의하락

.ATM switch, SONET 장비, POS i/f에비해장비가격이1/8정도저렴


Metro Optical Ethernet Network 구축비용

.비싼ATM과SONET장비가필요없다.

.Ethernet Switch들을Dark Fiber로연결


Overlay 구조를피함으로써운영비용의절감
