2 | Carrier Grade Ethernet Workshop, keynote speech, Krakow, April 30th 2008
TIGERTowards a Packet Transport Network
SDH and its optical layer is the most widespread transport technology TDM, circuit based
Carriers extended "smoothly" their circuit networks with packet transport capabilities 802.3, ESCON, FC… interfaces for link connection SDH next gen for packet services to circuit network adaptation bridges features for any-to-any connections
Carriers have a large panel of transport solutions current solutions : IP/MPLS, bridged Ethernet new trend : provide tunneling…
…with PBB-TE, PVT, T-MPLS… Connection Oriented wave to "carry" Carrier Ethernet services Similarly to circuit (SDH) and packet (MPLS) technologies

TIGERIntroducing "Carrier Ethernet"
Terminology invented by the MEF to qualify Ethernet Services E-Line (P2P EVC between 2 UNIs)
E-LAN (MP2MP EVC between >2 UNIs)
E-tree (P2MP EVC between root and spoke UNIs)
These services can be delivered over different types of networks (a.k.a "Transport network") Native Ethernet based (802.1, 802.3) Existing Packet transport networks (IP/MPLS) Existing TDM transport networks (SDH-NG, OTN)
Misuse of language of "Carrier Ethernet" that drifted towards marketing connotations People use to also include all technologies used to support Carrier
Ethernet services
Carrier Ethernet certification program performed by Iometrix

TIGERGoals of the Workshop
Bring together Experts of the different Carrier Ethernet services and transport technologies
Ethernet-centric: SPB, GELS, PBB-TE, etc. MPLS-centric: PW/MPLS, MPLS transport
Starting from Discuss various alternatives and confront them functionally Provide performance benchmarking results obtained for
these technologies
Open the floor for Scientific & Technical debate

TIGERStructure of the Workshop
Two tracks each divided into two sessions
Track 1: functional benchmarking
Two morning sessions (MI and MII) dedicated to functional benchmarking results per technology;
Track 2: performance benchmarking
The two afternoon sessions (Scientific and Technical Results AI and AII) dedicated to the performance benchmarking results per technology
- All sessions are organized 15/20 minutes presentation followed by 15 minutes of topical discussion -
After afternoon sessions, an open Scientific and Technical Debate (1 hour) will confront the scientific & technical results obtained by the workshop participants
