GRNET: owned fiber in South East Europe ready for e2e lamda
services (via GEANT2) Chrysostomos Tziouvaras MSc. GRNET Broadband
Infrastructures Development Manager Internet2 Member Meeting, April
23-25, 2007 Slide 2 2 Contents Introduction (Migrating from GRNET2
to GRNET3) Owned Fiber network WAN/MAN DWDM Optical design IP
aggregation architecture Switched circuit service Major networking
projects in SE Europe SEEREN2 SEELight Slide 3 3 Migrating from
GRNET2 to GRNET3 The GRNET network at its current state (GRNET2) is
built on leased DWDM lambdas for interconnecting IP routers The
next generation GRNET network (GRNET3) will be a hybrid network
built on owned (long term IRUs) DF links Slide 4 4 GRNET3 Fiber
Network Slide 5 5 Local connectivity Enable GRNET clients access to
the WAN DF cloud through Municipal Fiber Networks (MFNs) that are
currently built in most Greek cities expected to be available city
by city in 2008 Slide 6 6 Global connectivity Planned DF access to
GEANT2 by the end of 2007 Slide 7 7 GRNET3 fibers: terms of leasing
Single-mode fiber pair 15-year IRUs Availability 99% Monitoring and
failure reporting Failure recovery 3 days for repairing terrestrial
links 20 days for repairing submarine links Maintenance: downtime
cannot exceed 6 hours/year/link SLA for the optical characteristics
of the DF links (attenuation, CD, PMD) Collocation services at
terminal and intermediate sites Slide 8 8 WAN optical design DWDM
network ready for up to 21x10G lambdas without future addition of
EDFAs/DCMs The network is ready to implement the maximum number of
lambdas by just adding transponders At day 1 a limited number of
lambdas will be deployed BER less than 10-13 Minimization of
terminal nodes so as to ensure cost effective scalability R-OADM
ready: add/drop nodes can be in service upgraded to ROADMs Adequate
margins for safe operation Slide 9 9 MAN optical design Each GRNET3
client is O-SNCP protected Slide 10 10 GRNET3 IP aggregation
architecture GRNET3 will continue to provide IP services by using
the same principles followed up to now IP routers are installed at
major Greek cities IP routers will be interconnected with 2,5G PoS
framed lambdas implemented via GRNETs DWDM equipment Clients will
be aggregated to the local GRNET3 routers by using 1GbE framed
lambdas implemented via GRNETs MAN DWDM equipment Reuse of existing
IP equipment (Cisco GSR 12416/10) This aggregation architecture is
cost effective for GRNET3 clients with capacity requirements up to
1Gbps but not optimized for clients which are expected soon to
require 10Gbps capacity Two classes of GRNET3 clients: A limited
number of clients (hereafter called Power Clients PC) whose traffic
is expected to soon overcome the 1Gbps barrier The rest clients
(hereafter called Regular Clients RC) whose traffic is expected not
to exceed the 1Gbps barrier for the next 3 years Slide 11 11 PCs
aggregation to GRNET3 This deviation to the aggregation
architecture is driven by the high cost of 10G router interfaces
Slide 12 12 RCs aggregation to GRNET3 Slide 13 13 Switched circuit
service I Guaranteed capacity (1Gbps) service among selected GRNET3
clients, e.g. Grid clusters p2p 1GbE client interfaces Implemented
via NG-SDH switches interconnected with dedicated 10G WAN lambdas
Service provisioning options: Manually through the NMS Dynamically
through the GMPLS/G.ASON control plane NG-SDH switches will be
installed to Greek cities that host at least one Grid node (Athens,
Thessaloniki, Patras, Heraklio) Slide 14 14 Switched circuit
service II Slide 15 15 Equipment implementing GRNET3 GRNET procured
equipment for: WAN optical transmission MAN optical transmission
(Athens and Thessaloniki MANs) 4 NG-SDH switches L2/3 switch for PC
aggregation For the optical/SDH part contract was awarded to
Alcatel- Lucent (products: 1626LM, 1696MS, 1678MCC) Network
deployment until Oct 2007 For the IP part contract was awarded to
Cisco (product: Catalyst 6500) GRNET2 L3 equipment to keep in
operation (Cisco GSR 12416/12410) Slide 16 16 Major networking
projects in SE Europe - SEEREN2 SEEREN2 is an FP6 EC project
coordinated by GRNET SEEREN2 aims at further ease the digital
divide that still separates most of the southeast European
countries from the rest of the continent Interconnects the NRENs of
Albania, Bosnia & Herzegovina, FYROM, Serbia, Serbia and
Montenegro with GEANT2 SEEREN2 network operations and management is
performed by regional academic teams promoting international
cooperation and forming a virtual Network Operations Center (NOC)
Slide 17 17 Major networking projects in SE Europe SEELight I
SEELight is a project funded by 80% by the Greek State and the rest
20% by the beneficiary countries (Bulgaria, FYROM, Serbia, Romania)
- aiming at: materializing the South-East European Lambda Network
Facility for the regional research, academic and education
communities to enable the provision of end-to-end network services,
to meet user demands, to serve as a testbed for development of new
networks and services and to allow the SEE research and education
community to participate in international networking activities
establishing long term sustainability of NREN networks in South
East Europe deploying a South-Eastern European Network Operation
Centre (SEENOC). The SEENOC will ensure that network services and
operation is unobtrusive, will amass the necessary level of
competence and will foster development cooperation on all levels
Slide 18 18 Major networking projects in SE Europe SEELight II Main
cost categories of the project : the long-term leasing of fiber the
maintenance of the fiber the DWDM equipment acquisition followed
by: planning/design, technical assistance and supervision during
implementation and network operation Slide 19 19 Slide 20 20
