Introduction

Executive Summary

This document provides the test results for the Interoperability Testing for Converged Backbone Transformation (CBT) Port Level Grooming performed in the Alcatel-Lucent NAR IPTC Integration Lab and completed 11/20/09. Testing was based on the Converged Backbone Transformation Port Level Grooming (1625-7750) Test Plan Version 1.1[1]. Testing was performed to verify interoperability between the 7750SR and 1625LX as related to CBT Phase 1 Architecture

[2]. Additional information is available in the other references listed.

Scope of Testing

The interoperability testing for port level grooming focused on the functionality and operations of Alcatel-Lucent products. The test cases were limited to a subset of the overall requirements and addressed basic interoperability and functionality.

The scope of testing was constrained by the following items:

1. Test case configurations included epipes only. Service implementation, e.g., VLANs, epipes, QoS, priorities, marking, etc. were not defined in the requirements.

2. Various FRR scenarios (primary/secondary, primary/standby, etc.) were tested including basic FRR/SRLG. The FRR test cases included multiple failure points.

3. 802.3ah capabilities such as loopback validated at the product level. This is not in the scope of solution level validation. The only testing performed was for remote failure indication.

4. QoS test cases were added following completion of the initial interoperability test cases. The traffic distribution was assumed to be Voice (G.711 = 222 and/or G.729a = 82) 5%, Video (1518) 50%, and Internet (Imix) 45%. The reference bandwidth was 80% of the link rate, i.e., 8 Gbps.

5. QoS mappings were based on 802.1p marking. Voice traffic had the P-bit set to 5 which mapped to forwarding class EF which mapped to queue 6. Video traffic had the P-bit set to 4 which mapped to forwarding class H2 which mapped to queue 5. Internet traffic had the P-bit set to 0 which mapped to forwarding class BE which mapped to queue 1. These values were defined for sap-ingress and sap-egress and permitted using default network queue configurations.

6. Threshold failures were validated at the product level. This is not in the scope of solution level validation. Test cases measured detection plus failover. Test case passed if the failover time was less than 60 milliseconds, i.e.; the sum of the 10 milliseconds for detection and 50 milliseconds for switchover.

7. 7750 configuration was via the CLI. 5620 SAM requirements were not tested at this time. This was however tested in other test facilities.

8. Only resilience testing was for Fast Reroute and no Optical Layer protection.


9. Link failures tested included the following scenarios: a. Disconnect TX fiber b. Disconnect RX fiber c. Disconnect TX/RX fibers d. Disable interface 1 e. Disable interface 2 Note: Specific component (i.e. MDA, IOM, OT, OM, etc.) hardware failures were not tested. This is not in the scope of solution level validation.

10. The requirements do not discuss the type of XFPs. XFP-LRs (10GBASE-LR 1310 nm) were used in the 7750s for connections to the 1625s. XFP-SR1s (10GBASE-LR 1310 nm) and XFP-IR2s (10GBASE-ER 1550 nm) were used in the 1625s. The 7750 XFP-LRs support receive wavelengths to 1550 nm and interworked with the 1625 XFP-IR2s. XFP-SRs (10GBASE-SR 850 nm) were used for some connections between 7750s. Other XFPs were not tested.

Test Environment

Test Lab Components Table 1 represents the basic equipment used to support the interoperability testing. Tests performed after October 23rd used 1625LX R9.0.1.

Table 1 CBT Port Grooming Interoperability Test Components The 7750SR-7s were equipped with Integrated Media Modules (IMMs), Input/Output Modules (IOMs) and Media Dependent Adapters (MDAs) to provide the required 10GigE interfaces. The following equipment was used:

Quantity Description 2 IMM8-10GB-XFP 3 IMM4-10GB-XFP 2 M1-10GB-XFP

Table 2 7750 10G Components Depending on the configuration required for the test cases, the modules were installed in the appropriate 7750s. For example, in Figure 3 below, SR-A and SR-B each used an IMM8, SR-C and SR-MH each used an IMM4, and SR-CO used an IMM4 and two M20-10GB MDAs.


The 1625s used Optical Translators (OTs) consisting of both 10G transponders and 40G muxponders to connect to the 7750s. These were OT (10G XFP ADD-DROP Tunable) and OT (40G XFP MUX Tunable). Configurations were modified for the test cases to maximize the interoperability between the different 7750 and 1625 components. Note: Failover tests with the OT-10G failed. Based on these results, the existing OT-10Gs (WWCL01) were replaced with the new OT-10Gs (WWCL03). The WWCL03 version can be configured for overclocking. Additional tests were performed with these modules. With this configuration the failover tests passed.

Representative Test Configurations The testing used 3 basic configurations. The 7750SR-7s are designated with the SR prefix and the 1625LX with the LX prefix in the diagrams.

The following diagrams represent the 3 base configurations which were used in testing. The last diagram shows the actual “system 6” 1625 setup being provided in the optical labs for testing. It provides a detailed view of the 1625 components represented by the generic LX-A/LX-B unit diagrams shown in the configurations and also used throughout the document.

The first configuration, show in Figure 1, was used to test 10GigE interface interoperability and basic LAG functionality.

LAG Hashing Test Area: FUNC-006

Equipment:


Objective:

To verify LAG hashing operation. Notes: − The LAG hashing algorithm needs to be investigated to determine data streams and LSP

configurations. − The hashing algorithm for MPLS switched traffic is based on the whole label stack (up to 5

labels), along with the incoming port and system IP address. The EXP/TTL information in each label is not included in the hash algorithm.

− VLL traffic transmitted from a service access point (Etherpipe SAP) uses the service ID to pick one of the LAG paths.

Configuration:

Procedure: 1. Configure 8 VLAN epipes with control word. 2. Generate streams of bi-directional data over the VLANs using the STC. 3. Verify that the data is flowing over the LAG and record the physical interfaces used and

the VLANs assigned. 4. Verify that no data is lost. 5. Disconnect one of the LAG ports.

Scope

This document details Network Integration test scenarios for inter-working between 7750SR-12 and 1678MCC equipment for CBT project (Converged Backbone Transformation).


7750-1678MCC interworking TESTS

Introduction

In the context of CBT R1.0 Network Integration intends to test interworking between 7750SR and 1678MCC at 10GbE sub-port grooming level.

Network Elements and test equipment Network Elements involved in the tests are:

- 1678MCC 4.5.1

- 7750SR R7.0r4 Basically, a ring of 1678MCC is requested for transport of the 7750SR 10GbE lines. We will include , ASON restoration and SNCP protected configurations.

Three 7750SR will be used with B&W 10GbE interfaces on transport side. The XFP type used was ALCATEL 1AB214540001 with 1310nm LC 10GBASE-LR 10GBASE-LW with a link length support of 10km for SMF.

Spirent TestCenter testing analyzer will be used for end to end traffic testing.

Network Management Network Elements will be managed through:

- 1353NM + 1354RM for 1678MCC ASON and SDH configuration.

- CLI for 7750SR

Network Integration testing restrictions We have to consider for this Network Integration test campaign:

- 5620 SAM manager testing is not in the scope

- 1340 INC manager testing is not in the scope

- Spirent Test Center will be used to check end to end traffic (GbE interfaces). It is not planned to set up video servers, internet traffic or voice traffic.

- No interworking tests at 1GbE rate are planned

This document details Network Integration test scenarios for inter-working between 7750SR-12 and 1830PSS equipment for CBT project (Converged Backbone Transformation).


7750-1830PSS interworking TESTS

Introduction

In the context of CBT R1.0 Network Integration intends to test interworking between 7750SR and 1830PSS-32 at 10GbE port grooming level.

Network Elements and test equipment Network Elements involved in the tests are:

- 1830PSS-32 R1.1

- 7750SR R7.0r4 Basically, a ring of 1830PSS is requested for transport of the 7750SR 10GbE lines. We will include unprotected configuration, O-SNCP and OCH protected configurations.

Three 7750SR will be used with B&W 10GbE interfaces on transport side. The XFP type used was ALCATEL 1AB214540001 with 1310nm LC 10GBASE-LR 10GBASE-LW with a link length support of 10km for SMF.

Spirent TestCenter testing analyzer will be used for end to end traffic testing.

Network Management Network Elements will be managed through:

- 1354PhM for 1830PSS Optical Commissioning.

- 1350OMS 9.1.1 for 1830PSS traffic management. For info, current 1350OMS 9.1.1 is a development release not yet DR4. 1350OMS 9.1.1 is the first release managing 1830PSS.

- CLI for 7750SR

Network Integration testing restrictions We have to consider for this Network Integration test campaign:

- 5620 SAM manager testing is not in the scope

- 1340 INC manager testing is not in the scope

- 1350OMS is used to manage 1830PSS but the 1350OMS testing is already part of Network Release tests.

- Spirent TestCenter will be used to check end to end traffic (GbE interfaces). It is not planned to set up video servers, internet traffic or voice traffic.

- No interworking tests at 1GbE rate are planned
