230 Optical Ethernet Solution
• The Passport 8600 Ethernet Routing Switch –
delivering layer 2-7 intelligence that enables not
only the switch and routing of frames
and packets, but the manipulation of content
flows across servers. The Passport 8600 brings
leading scalability, port density and performance,
while providing the depth for new multimedia
application demands through extensive
multicasting capability and extended
prioritisation and queuing mechanisms
• The OPTera Metro 5200 – intelligent metropolitan
optical solution, enabling Enterprises to extend
the capacity and capability of their fibre assets.
The OPTera Metro uses DWDM and CWDM
technologies to increase the number of
wavelengths traversing a fibre, and through its
protocol and bit rate transparency, can support
any optical service up to 10Gbps – IP, ATM,
Ethernet, ESCON, Fibre Channel, FICON, PDH, SDH,
SONET, Digital Video etc. Wavelength efficiency is
achieved by a rich set of sub rate multiplexer
cards. The OPTera Metro 5200 allows Enterprises
to extend fibre capacity up to 240Gbps if required,
while preserving the ability to offer individual
wavelengths 50mS protection switching for high
availability applications.
Nortel Networks provides end-to-end service
connectivity through the integration of its OE and IP
Services portfolios. Applying the scenario in the
diagram below, in-building LANs are interconnected
using the Business Policy Switch 2000 (BPS 2000)
and the Passport 8600 Ethernet Routing Switch.
The BPS2000 collects the floor-by-floor Ethernet
connections and after applying QoS measures,
performs layer 2 switching of the packet to the
Passport 8600 through a gigabit uplink. The
Passport 8600 enables internal routing between
BPS2000s, further QoS and queuing mechanisms
and provides the external connection to the network
at rates up 10Gbps. Metropolitan connectivity can be
achieved through clustering of Passport 8600s over
dark fibre connections, or by interfacing localised
Ethernet deployments onto an optical backbone
with Ethernet on SDH supported by OPTera Metro
4000, or DWDM with the OPTera Metro 5000 series
of metropolitan optical transport solutions.
