2 Alcatel-Lucent TPSDA Performance Verification Testing - Executive Summary _____ Isocore Internetworking Lab 3 EXECUTIVE Summary This Summary Report presents the results of a comprehensive triple play service delivery architecture (TPSDA) validation and performance verification conducted independently by Isocore . The test series focused on an extensive evaluation of Alcatel-Lucent s feature set related to large-scale residential triple play deployments with enhanced subscriber management while supporting a very high number of mixed enterprise virtual private network (VPN) services over a single Internet Protocol, MultiProtocol Label Switching (IP/MPLS) network. Testing was conducted with the Alcatel-Lucent 7750 Service Router (SR) and the 7450 Ethernet Service Switch (ESS). Both products performed exceptionally well under extreme scaling conditions imposed by the test series.

3 Alcatel-Lucent demonstrated a flexible end-to-end solution for a variety of deployment methods necessary in increasing Quality of Experience of any subscriber in a large scale triple play environment. KEY FINDINGS The Alcatel-Lucent TPSDA, 7750 SR and 7450 ESS platforms and related triple play feature set exceeded the triple play requirements set forth by Isocore for this test series. The key findings of the evaluation include: The base network scaled to 120,000 active subscriber hosts and more than 43,000 enterprise class Layer 2 and Layer 3 VPN services. The enhanced subscriber management (ESM) feature set performed the process of subscriber identification and instantiation of policies and resources across all test scenarios. Traffic forwarding to all residential and enterprise services were not impacted beyond the microsecond level when control processor modules (CPMs) were failed over.

4 The security feature set demonstrated the network was secure and no intrusion attempts were successful. The QoS feature set of Alcatel-Lucent 7750 SR and 7450 ESS platforms is able to maintain subscriber Service Level Agreements (SLA) under severe congestion and separate subscribers at the forwarding plane level. The systems were stable under considerable stress through numerous iteration and test cycles. Based on this comprehensive evaluation it is clear to Isocore that Alcatel-Lucent offers a complete end-to-end triple play solution. The 7750 SR and 7450 ESS that form the core of the solution support a scalable mix of residential triple play and enterprise services. The consistency of results produced through multiple iterations of testing assures the non-stop delivery of all services. The end result of testing validated that what was presented in the lab is deployable.

5 Alcatel-Lucent TPSDA Performance Verification Testing - Executive Summary _____ Isocore Internetworking Lab 4 1 TEST OVERVIEW AND FOCUS As part of its advanced triple play and IPTV certification tests Isocore evaluated Alcatel-Lucent s triple play service delivery solution for its ability to meet the strict requirements of a scaled residential triple play deployment. Isocore s evaluation focused on Alcatel-Lucent s TPSDA and the ability of the 7450 ESS and 7750 SR to support scaled residential services. Although residential triple play services were the primary focus, a highly-scaled deployment of Layer 2 and Layer 3 VPN services was added to the topology to demonstrate that the network and platforms are capable of carrying both residential triple play services and enterprise class VPN services simultaneously. The base network included 120,000 active subscriber hosts and more than 43,000 enterprise class Layer 2 and Layer 3 VPN services.

6 Table 1 provides a Summary of the significant scale achieved during the event. Under these highly-scaled conditions, Isocore performed a thorough analysis of all aspects of residential triple play service delivery. This included an in-depth evaluation of Alcatel-Lucent s subscriber management, hierarchical quality of service (H-QoS), security, subscriber host authentication, high-availability, resiliency feature, and operations administration and maintenance (OAM), as well as a thorough analysis of a flexible architecture.

7 Minimal traffic loss to residential subscribers for duration of s s with high-availability Traffic prioritization of VoIP, VoD and broadcast TV (BTV) service. No traffic loss for VoIP, VOD, and BTV traffic under heavy congestion No packet loss during long duration traffic forwarding tests (10-12 hrs run) This test was the first of its kind in the industry to focus on validating the ability to deliver a highly-scaled mix of residential triple play services and enterprise VPN services. The challenge of a test like this is the multi-faceted and complex nature of the effort. The execution included careful design and preparation and hundreds of hours of actual testing. The level of stress imposed on the network, architecture, and systems under test was significant. Alcatel-Lucent TPSDA Performance Verification Testing - Executive Summary _____ Isocore Internetworking Lab 5 The end result validated that what was presented in the lab is truly deployable.

8 Numerous iteration and test cycles were performed and the systems were extremely stable under considerable stress. The related triple play ESM feature set is comprehensive, assuring that residential triple play service deployments are highly manageable. The systems and architecture can support stringent SLAs per subscriber and provide the security required for residential services. The high-availability and related resiliency feature set assured the reliability of the residential and VPN services. In short, the Alcatel-Lucent TPSDA, 7750 SR and 7450 ESS platforms and related triple play feature set exceeded the triple play requirements set forth by Isocore for this test series. TEST METHODOLOGY AND SYSTEM TEST SETUP Figure 1 provides an overview of the test network setup. The setup used two, fully loaded 7450 ESS-7s as broadband service aggregators (BSAs).

9 Each of the 7450 ESS-7s was equipped with nine 10-port Gigabit Ethernet media dependent adapters (MDAs) and one 2-port 10 Gigabit Ethernet MDA. BSAs aggregated traffic from directly connected DSLAMs using a VPLS-based TPSDA. Two 7750 SR-12s were setup as broadband service routers (BSRs) to aggregate the BSAs and support direct connections from DSLAMs when an aggregation network is not required. For this event the BSR used a routed TPSDA model for DSLAM aggregation. The BSRs were equipped with a variety of 10/100/1000 Gigabit and 10 Gigabit Ethernet MDAs. A 7750 SR-7 was used as a gateway for content delivery. The Agilent N2X Multiservice Test Solution was used as the source for high-speed Internet (HSI), BTV multicast content, vdeo on demand (VOD), voice over IP (VoIP), and signaling all active subscriber dynamic host configuration protocol (DHCP) sessions through the DHCP server.

10 All 7450 ESS and 7750 SRs were running SR_OS version The Agilent N2x also emulated all hosts on the network.
