GÉANT Lambda Service Description
GÉANT Lambda
Overview
The GÉANT Lambda service provides dedicated, transparent 10Gbps, or 100Gbps
wavelengths between any two GÉANT PoPs on the dark fibre cloud (40Gbps circuits may be
available on application). The service is of benefit to those users having extreme networking
demands, for example large-scale research projects that need to transfer huge amounts of
data between sites via a dedicated (guaranteed capacity), highly resilient and secure
connection.
GÉANT Lambda services can be provided protected or unprotected. Protected Lambdas are
available on request, and will be granted based on the availability of protected bandwidth.
GÉANT Lambda services can be connected to non-GÉANT organisations, including
transatlantic destinations. Requests for those connections can only be fulfilled if GÉANT
infrastructure exists to deliver the circuit to the proposed interconnection point. Circuits may
be established to non-GÉANT destinations upon request and pending approval by the
GÉANT Executive Board.
Robust: Same award-winning levels of support and resilience offered by the GÉANT
network.
High capacity: Up to 100Gbps services available.
Reliable: Resilience options offering up to 99.999% availability.
Flexible: End-to-end dedicated connections allow greater protocol flexibility.
Guaranteed capacity: Guarantees PoP-to-PoP bandwidth, capacity delivered over
10Gbps, 40Gbps or 100Gbps interfaces.

Technical Description of the Service
Infrastructure
The GÉANT Lambda service is delivered on the Infinera Intelligent Transport Network,
featuring a DTN-X packet optical transport networking platform. The DTN-X platform
provides transmission capacity using a 500Gbps super-channel based on FlexCoherent
Photonic Integrated Circuits (PICs), built-in OTN (ITU G.709) which can be switched with
granularity 1Gb/s, non-blocking OTN cross connect. This means that the 500Gbps line
system is pre-provisioned to be ‘always on’ and available on demand to any client interfaces.
Service Options
The following options are available for the GÉANT Lambda service: Unprotected Lambda, ,
SNCP Protection and Fully Protected (or “1+1”)

Unprotected Lambda: Provides no optical or route protection. The unprotected
lambda services provide no optical protection of the signal. If a card/optics failure or
a fibre cut should occur along the optical signal paths, the circuit cannot reroute.

SNCP Protection: SNCP protection offers the added security of a second route
without the complexity of a second circuit. This protection mode is implemented
using the SNCP protection offered by the DTN-X. With this option enabled, GÉANT
Lambda is able to reroute under 50ms in case a single circuit failure occurs. Protected
lambdas can be provided with auto-recovery, meaning the service is automatically
switched back to the original circuit when restored, or with manual switching back to
the original circuit by DANTE at an agreed time.

Full Fibre and Optic Protection (1+1 protection): The ‘fully protected’ option offers
a complete backup path, including the client interfaces. This option offers two GÉANT
Lambdas routed over different paths, leaving it up to the user to select which one to
use. In full protection mode, path selection is left to the end user if two circuits are
delivered. This offers complete control to the users.
GMPLS Restoration
If there is spare capacity on an alternative path across the backbone network, then if the
primary path is interrupted the Intelligent Transport Network will attempt to re-route the
lambda. This re-routing will take up to one minute to complete. As it depends on spare,
unmanaged capacity, GMPLs Restoration is available only on a best efforts basis. As such the
Service Level Targets are the same as for the Unprotected Lambdas.
GÉANT Lambda Service Description
Demarcation Point
The management demarcation point between DANTE and the NREN is a port on the rack
Optical Distribution Frame (ODF), as described in the figure below.
Figure 1: Illustration of the management demarcation point
The exact port will be specified at the time of the connection. The responsibility of the
GÉANT Operations ends at the declared demarcation point, patching beyond that point is
the responsibility of NREN requesting the service.
Lambdas to Destinations Outside of Europe
Direct Lambda connection from a GÉANT location (see Annex) to non-GÉANT organisations
or destinations is possible. Any bespoke requirements will be evaluated by the GÉANT
technical teams on a case-by-case basis to offer the best available solution.
The Service Level Agreement (SLA) outlined in this document is valid only between GÉANT
PoPs, any bespoke solution will have a specific SLA based on the offered solution.
Please contact GÉANT Partner Relations for further information on available destinations:
partner-relations@geant.net.
GÉANT Lambda Service Description
Service-Level Target
Availability Target
The unavailable time of GÉANT Lambda Service is calculated between any two GÉANT PoPs.
The targets are calculated annually for complete loss of traffic on the GÉANT infrastructure
(fibre cut), excluded planned maintenance.
For an unprotected lambda, the availability target is 99.5% up to 1000km and then reduced
by 0.5% for every 1000km.
