To assure the highest degree of LAN performance, there must be traffic management capabilities that balance bursty traffic, interactive traffic, real-time latency-sensitive traffic, and non-realtime traffic. Tellabs Optical LAN can accomplish the highest LAN performance through traffic segmentation, low latency and QoS mechanisms, while greatly improving network security compared to the legacy copper-based LAN alternative.
Segmentation
Legacy copper-based LANs that place all traffic in a single broadcast domain can easily overload the network. The better design is to segment traffic through advanced VLAN capabilities. Optical LAN allows service-level VLANs that segregate and secure data flows to Optical Network Terminal (ONT) Ethernet ports.
VLAN trunking, termination, and translation allow for rate shaping on a per-service basis. Traffic classification guarantees voice quality and, with VLAN trunking, you can support multiple services and multiple end devices per ONT Ethernet port.
Latency
Increasing bandwidth capacity does not directly equate to better network performance. There are issues to consider that are directly related to latency: jitter, packet loss, and congestion.
Reducing the number of optical-to-electrical and electrical-to-optical conversions results in better network performance and lower energy consumption. In fact, Optical LAN can eliminate all of the O-E-O conversions over an 18-mile reach.
Quality of Service
Strict QoS is delivered through Optical LAN via traffic segmentation/classification, rate limiting, policing, queue management, scheduling and shaping mechanisms.
This traffic classification is done on all ingress traffic based on traffic type defined for the VLAN during provisioning. Rate limiting and policing are defined by setting Committed Information Rate (CIR), Excess Information Rate (EIR) and Access Control List (ACL) filters. This sets the guaranteed bandwidth per user, per service or per end device, while smoothing bursty traffic and establishing ultimate rate limits.
Global Profiles Ease Management
Tellabs Optical LAN allows network managers to create global profiles related to particular services, segmentation, QoS and security that can then be aligned with specific users and IP/Ethernet end points. If a user moves to a new location, those profiles automatically follow the user. This helps speed the process of Moves, Adds and Changes within the LAN, simplifying day-to-day network management.
