The integration of CWDM and DWDM SFPs eliminates the need for a transponder on the network, and offers better fiber optimization along

physical services separation with dedicated Gigabit rate for premium optical services with the same concept of legacy“leased-line”services.

VPN Services & Protection

Compliant to MEF Ethernet Virtual Circuit (EVC), the OS900 can offer three types of VPNs:

1.

Layer 1 Optical VPN – a cross-connect mode with transparent mode (no MAC learning)

2.

Layer 2 VPN – VLAN-based tunneling Q-in-Q stacking, swapping or mapping services

3.

Layer 2.5 VPN – a label-based MPLS VC for direct connection into MPLS domains or H-VPLS MTU-s

All the aboveVPN services can be fully protected using port redundancy,dual-homing,and/or ring topology with a recovery time of less than 50 ms.

In addition to L2 VPN, the OS900 can offer integrated IP router services to save the costs of an external router and provides a single demarcation

platform for managed L2 VPN and IP services.

Traffic Management

The OS900 enables a value-added network infrastructure, with end-to-end per flow QoS.

It supports full CoS and QoS (MEF 14 model) including flows classification, rate limiting, shaping, WFQ scheduling, and strict priority for lower

delay/jitter and guaranteed throughput in real-time applications. In addition, it enables dynamic/adaptive buffer pools to prevent bursty traffic

starvation and ensure queuing resources effectiveness.

For network convergence applications that have a clear boundary between customer’s and carrier’s networks, CoS layers (802.1p, IP ToS & MPLS

EXP bits) can be mapped/marked to preserve priorities or map them into predefined protection profiles set by the carrier.

Hierarchical QoS – CoS-Aware rate limit

Defining premium SLAs is a key fundamental for service differentiation.

The OS900 enables traffic management based on innovative CoS-aware rate limit to dynamically reuse bandwidth profiles. Dynamic QoS is an

important feature that allows for sharing defined rate limited flows with aggregate profile applied to a user network interface or an Ethernet

Virtual Circuit. In the new service offering, the consolidated real-time, high-priority and best effort data require different rates and marked class

of service. Dynamic QoS helps to share/borrow the bandwidth that was allocated for real-time or high priority applications at a time when these

services are not active. Such an offering contributes to a more efficient way of provisioning bandwidth at the access/demarcation of the network

without complex configuration sets at the aggregation layer.

Denial of Service (DoS) protection

The OS900 incorporates multilayer DoS protection at the hardware architecture on the CPU control plane and data-switching plane. The

multilayer control protects the service and the device functionality from hostile traffic without degradation of service performance or affecting

of the forwarding database or CPU availability. Multiple traffic types can be policed or discarded starting from frame level such as broadcast,

multicast up to IP/TCP/UDP layers.

Management

The OS900 Series control plane incorporates a list of highly manageable feature that offers ensured interaction with carrier’s OSS and NMS

platforms, based on industry standard Southbound out-of-band or in-band interfaces. In addition, it can be managed via MRV’s MegaVision-Pro

NMS to have complete GUI and Northbound gateway (XML, TL1 & SNMP) of an entire map of clustered devices for configuration, performance

analysis, and inventory control.

For the service providers, the OAM that is provided by a demarcation device determines to a significant extent the metrics that can be used to

establish the SLA with a business subscriber. The OS900 incorporates enhanced standards compliant MEF OAM and gives the service provider

the ability to monitor the network and provision services, and promptly determine the location of faults remotely from the network operation

center.

Ethernet OAM with IEEE802.1ag & ITU-T Y.1731

The connectivity of Ethernet bridge devices across Metro Ethernet or

other transport networks creates dedicated or virtual Ethernet circuits. An

end-to-end service architecture requires administrative domain hierarchy

with corresponding OAM enabled titles. The OS900 Series incorporate

connectivity,discovery and fault management along performance statistics

of delay, jitter and frame loss for demarcation and intermediate points of

service.

Ethernet loopbacks

The OS900 Series offers remote loopback functionality on a physical

interface or a specific VLAN that traverses UNI or NNI interfaces. The

loopback function allows for the troubleshooting of the service,

remotely, from NOC, or any other manageable location without

needing to actually visit the customer premises. Loopback functionality

performed in hardware level for performance monitoring and SLA

verification in wire-speed.

Copper TDR

The OS900 incorporates copper TDR that can identify problems with

CAT5 copper cables on a customer’s site such as opens, shorts and

wrong impedance.

Optical Performance Level Monitoring (Digital Diagnostics)

The OS900 Series supports the SFP Digital Diagnostics standard (as per SFF-8472). A powerful OPM tool, it provides access to a number of real-time SFP

operating parameters such as optical TX/RX power,voltage and temperature,as well as component information such as vendor code,serial number and

wavelength.The information provided by Digital Diagnostics, together with alarm and warning thresholds, enables a network administrator to identify

potential problems in optical transmission and take preemptive action before any service outage actually occurs.

Per-service performance monitoring

The OS900 offers real-time and historical reporting on various service performance metrics, including port/VPN-EVC utilization, transmission

errors, and QoS threshold exceptions.
