High Availability, Reliability, and Fast Resiliency

The LE-3300 with it’s carrier-class architecture meets the challenge of providing continuous system availability and reliability in Carrier Ethernet deployments. LE-3300 carrier-class reliability and resiliency is supported through highly available hardware architecture by leveraging the following advanced hardware design components:

  • Hot-swappable Line and Control Modules, Fan Tray, Power Supplies, and Alarm Module
  • 1:1 redundant Control Modules
  • Link Protection for 10 Gigabit & 1 Gigabit Ethernet for both equipment and facility failures
  • Redundant and load-shared AC or DC power supplies
  • Redundant fans for resilient cooling
  • Removable Compact FLASH on Control Module, for fast access to the base LE-OS kernel, LE-OS load modules, alternate LE-OS images, and system-specific configuration files

The LE-3300 provides software reliability and resiliency needed to maintain network uptime by supporting the following major features:

  • Modularized distributed LE-OS software architecture with a real time kernel
  • Industry-leading resiliency with Rapid Spanning Tree Protocol (IEEE 802.1w) offering sub-50 millisecond failover and restoration
  • Industry standard IEEE 802.3ad Link Aggregation with Link Aggregation Control Protocol (LACP)
  • End-to-End Services resiliency using CFM (802.1ag etc.)
  • Link Level Keepalives or Status exchanges
