Multi-Dwelling/Tenant Units

Multi-dwelling and multi-tenant units present especially challenging requirements for access service providers including: maintenance of secure and stable communications between all subscribers, service isolation to prevent inter-service congestion, and provisioning and enforcement of service level agreements for sensitive traffic such as cellular backhaul (often found on rooftops). Additionally, it is often impractical to replace the building communication infrastructure.

Teknovus’ EPON architecture provides the foundation technology required for reliable high-performance deployment to MDU/MTU buildings:

2.5Gbps Turbo-EPON™ downstream data rate supports more than 50 to 100 HDTV streams while leaving 1Gbps for data traffic or enables high split ratios for reduced CapEx;
Field-proven hardware-based DBA guarantees SLA service contracts, maintains bandwidth-allocation fairness, and optimizes link utilization;
ARP snooping, ARP proxy, and Precise ARP support provides faster response and prevents a variety of malicious user attacks;
Multicast Group (MG) traffic management minimizes channel zap time and enhances image quality by minimizing packet loss, latency, and jitter;
Comprehensive rule-based packet classification enhances network security, SLA enforcement, and supports billing applications;
Over twenty VLAN modes allows flexible VLAN configuration, service to VLAN mapping, traffic classification into VLANs, and VLAN tag manipulation for service and management domain transition;
China Interoperability Mode support (OAM extensions, triple-churning key encryption) is fully compatible with CTC requirements for China EPON deployment;
IPv4 and IPv6 support provides compatibility with latest next-generation network deployments and service upgrades.

The drawing below illustrates how Teknovus' multiple LLIDs/ONU enable multiple services to share the ONU without affecting each other's QoS. For example, starting from the telephone on the right, its traffic is classified within the ONU and placed in a queue for LLID1. Traffic for LLID1 travels up the EPON to the OLT where it is deposited in its unique queue, where it is shaped and scheduled for transmission out the NNI (Network-Network Interface).
