World Wide Packets 

LightningEdge® Operating System (LE-OS)  

Advanced Quality of Service

World Wide Packets is a leader in the implementation of true Carrier Class QoS in a cost effective and scalable Ethernet access environment. LE-OS supports a flexible QoS implementation that permits a wide range of traffic types and rates to be delivered over a single access infrastructure without interference or degradation.

LE-OS implements Carrier Class QoS that tracks creation, implementation, enforcement, and monitoring of all QoS parameters. Tracking is based on:

  • Flexible QoS implementation, based on service mapping and service level definition (including Committed Information Rate, Excess Information Rate, and Priority)
  • Sophisticated congestion handling based on CIR, EIR, and Burst Priority settings
  • Automated service provisioning resulting in more comprehensive deployment of QoS while significantly lowering the cost of implementing QoS

Figure 1. Multiple Services with LE-OS Hard (Explicit) QoS

The LE-OS QoS implementation enables network operators to simultaneously deliver any service or combination of services, such as voice, multicast video, Internet access, and Transparent LAN, to any mix of business or residential customers. These capabilities enable greater revenue generation by more efficiently utilizing available network resources while at the same time improving customer relations with enforceable and reliable Service Level Agreements (SLAs).

LE-OS Quality of Service Features

Guaranteed bandwidth for SLAs based on Carrier Class programmable and hard QoS can be provisioned explicitly and independently as well as consisting of any combination of minimum guaranteed bandwidth, burstable bandwidth, and jitter and delay tolerance.

  • DiffServ classification and remarking with Dual-rate, 3 color, “leaky bucket”
  • Classification based on L1/L2/L4
  • Protects both Unicast & Multicast Traffic
  • Enables Protection of management traffic and high-revenue traffic
  • Flexible service mapping:
