LightningEdge® Operating System (LE-OS)  

Reliability, High Availability, and Resiliency

LE-OS delivers Carrier Class reliability and availability that both metro and enterprise operators expect and demand for today’s business-critical network services. LE-OS resiliency and reliability are based on three major features:

  • Modularized software architecture with a real-time kernel
  • Industry-leading resiliency with Rapid Spanning Tree Protocol (IEEE 802.1w) that can be configured to support sub-50 millisecond failover time*
  • Industry-standard IEEE 802.3ad Link Aggregation

*RSTP performance will vary by size and configuration of the network. Sub-50 millisecond failover time based on a real-world test configuration with a 7-node ring and 8,000 MAC addresses. For more information on this test, see World Wide Packets White Paper entitled “Network Resiliency”.

LE-OS is architected with a real-time kernel that delivers reliability and high availability by protecting against complete operating system failures.

LE-OS also delivers industry leading resiliency with an advanced optimization of the Rapid Spanning Tree Protocol (IEEE 802.1w). LE-OS can be configured to deliver less than 50 Millisecond failover times to support time-sensitive applications such as video and voice. The rapid failover capability of LE-OS enables deployment time-sensitive applications with the same service level guarantees as SONET/SDH optical rings while at the same time being fully compatible with IEEE Spanning Tree and Rapid Tree Spanning Tree Protocols.

LE-OS also support IEEE 802.3ad Link Aggregation. 802.3ad supports bundling of several physical ports together to form one logical port. LE-OS Link Aggregation is a standard implementation of 802.3ad and delivers both interoperability and resiliency of the connection even if connectivity with one physical port is interrupted. LE-OS Link Aggregation support includes the Protection Link Aggregation feature that delivers a “hot standby” failover mechanism which provides a near wire-speed protection mechanism for the protected link aggregation group. When the failed like is restored, reversion to the initial configuration is programmable. LE-OS also supports ingress policing across a link aggregation enabling more efficient utilization and sharing of bandwidth among ports.
