Customer Profile
• Large Enterprises with mission-critical backbone
internetworks
• Multivendor, multiprotocol environments
Typical Applications
Multiprotocol core routing
Key Points
The BN products feature a symmetric multiprocessor
architecture that uses multiple MC68040- or
MC68060-based Fast Routing Engine (FRE)
processors, multiple dual PowerPC microprocessor-
based ATM Routing Engine (ARE) processor modules
and a 1 Gbps Parallel Packet Express (PPX) to deliver
industry-leading performance and availability.
Configured with Nortel Networks Routing Services
(BayRS) software, the BLN and BCN provide
multiprotocol routing and bridging, to maximise
connectivity and interoperability in multivendor,
multiprotocol environments. Comprehensive
hardware and software redundancy features
provide complete fault resiliency, while dynamic
reconfiguration and hot-swap features allow on-line
changes in hardware and software configurations.
