2 FlexE Test Application FlexE is an Implementation Agreement defined by the Optical Internetworking Forum (OIF) to address the need for more flexible and scalable bandwidth serving high speed Ethernet rates. FlexE evolved out of specialized solutions like Link Aggregation (LAG) and Multi-Link Gearbox (MLG). It provides functionality for Channelization, Bonding and Subrating applications to connect one or more Ethernet s using standard Ethernet PMDs between routers. Routers can be connected directly or through transport gear as illustrated in the three examples in Figure 1. Transport Network 3 Client 100G 200G Router 3 x 100GBASE-R PHY Low skew FlexE Terminated 300G FlexE clients carried over transport network Channelization 1 Bonding 50G 50G 200G 2 Sub-Rate FlexE Aware 25G 125G Router 10 out of 2 x 20 as unavailable slots 2 x 100G FlexE Section Management Channel Sub-rate 150G High skew All PHYs of FlexE group over same fiber route 25G 125G Discard unavailable slots FlexE Unaware 25G 150G Router 2 x 100G FlexE Calendar with 5 unused slots 2x100G High skew All PHYs of FlexE group over same fiber route 25G 150G Figure 1. Examples for FlexE use cases include Bonding, Channelization and Sub-Rating with Transport Network Equipment in FlexE Terminate, FlexE Aware and FlexE Unaware operation modes. 2 FlexE Software Option for ONT QFLEX and 400G Module

3 In essence, FlexE dissociates the Ethernet on the client side from the actual physical interface as illustrated in Figure 2 The following llustration shows clients can be mapped across multiple PHYs through the 20 slots in subcalendar per PHY.

Enhanced Ethernet Layer model with FlexE is an important building block for SDN networks as it allows network managers to adjust the network configuration by adding or removing clients from the service for typical use cases as shown in table 3. Segment Use Case Benefit Operators Flexible Ethernet Services Enables SDN with lower cost per bit and new attractive Services Data Center Interconnect (DCI) Carrier Ethernet Router to high-speed optical Transport networks Full rate utlization of existing transport network Intra-Data Center Using large pipes Cost efficiency.

4 IC vendors, network equipment manufactures and network operators need a test environment to validate and verify FlexE protocol mechanisms that span across multiple clients and PHYs. Table 4 summarizes key ONT FlexE test functions. FlexE Test Case Calendar Client Setup RX PHY and Calendar Map FlexE Alarms & Errors FlexE Overhead Manipulation FlexE Management Channel Port Skew 64B/66B Reconciliation What Needs to be tested? Setup of multiple clients with different client sizes to support applications for bonding, channelization and sub-rating. PHY Map for entire FlexE Overhead Multi-frame and Sub-calendar map per time slot and associated client number VIAVI ONT test set provides unique Alarm & Error tests that help analyze FlexE Overhead logic and interoperability between network elements User manipulation of any bit in the FlexE Overhead and Overhead Multi-frame to provoke unusual configuration, device and network conditions User defined bit loading in the Section-to-Section and Shim-to-Shim Management Channels Skew between PHYs because too-high PHY skew might cause payload not to be reconstructable 64B/66B Block analysis per FlexE client. Including Local and Remote Fault / IP FlexE client rate, utilization, QoS, errors Table 4. ONT FlexE key test functions 4 FlexE Software Option for ONT QFLEX and 400G Module

5 Alarms & Errors The ONT FlexE test application introduces specific FlexE alarms and errors as listed in table 5. Local Fault (LF) as defined in the OIF FlexE implementation agreement is presented on the ONT 64B/66B layer together with Remote Fault. Test Metric Type Use Case LOGA (Loss of Group Alignment) Alarm Indication that payload cannot be reconstructed Group Numbers Inconsistent Alarm Accepted FlexE group numbers are not identical across the group. PHY Numbers Inconsistent Alarm Accepted PHY numbers do not match the accepted PHY map on one or more PHYs PHY Maps Inconsistent Alarm Accepted PHY maps are not identical across the group. Calendar in Use Inconsistent Alarm Accepted Calendar in use does not match across the group. LOF (Loss of FlexE Overhead Frame) Alarm Lock to FlexE Overhead frame LOMF (Loss of FlexE Overhead Multi-frame) Alarm Lock to FlexE Overhead Multi-frame RPF (Remote PHY Fault) Alarm Inform far-end shim of locally detected failure of the PHY GNM (Group Number Mismatch) Configuration Alarm Accepted group number does not match the RX configured value. PNM (PHY Number Mismatch) Configuration Alarm Accepted PHY number does not match the RX configured value PMAPM (PHY Map Mismatch) Configuration Alarm Accepted PHY map does not match the enabled PHYs. CM (Calendar Mismatch) Configuration Alarm TX/RX calendars in use don t match CCM (Calendar Configuration Mismatch) Configuration Alarm Accepted calendar of the Accepted calendar in use is different from the configured RX calendar of the RX calendar in use. OH Block #1 Error Error Overhead anchor block error CRC-16 Error Error CRC-16 to protect FlexE overhead. Only PHYs from overhead frames with good CRC are accepted. C-Bit Error Error 3 C-Bit in majority vote define the Calendar in Use. Table 5. ONT FlexE key test functions 5 FlexE Software Option for ONT QFLEX and 400G Module
