Miercom Lab Testing Report for Microsoft Lync 2010

Microsoft® Lync™ Server 2010 delivers complete presence, instant messaging, conferencing and enterprise voice capabilities through a single, easy-to-use interface that is consistent across PC, browser, and mobile device. Administrators benefit from a single, consistent management infrastructure, new capabilities to increase availability, and interoperability with existing systems.    Visit the Microsoft Lync site for more details about the product including benefits, guides, and research data.

On January 25, 2010 Miercom released a Lab Testing Detailed Report for Microsoft Lync 2010.  One quote from the report highlights the scalability and performance of the platform:

Microsoft Lync Server 2010 was able to sustain heavy call volume without dropping any calls or reporting any errors in a 4 million call completion test. The delivery rate with sustained operation without error is the highest capacity test applied to any Unified Communications / IP PBX product we have tested to date.

I have been using Lync for a while now as my primary business phone,web conferencing and IM solution.  I have Lync installed on a laptop that travels all over the United States with me and I can always rely on having a dial tone whenever I locate an Internet connection.   I have been amazed at the audio quality of my calls even when they have been made over a 3G wifi hotspot connection.   It doesn’t matter if I am in the office,at home, in an airport or at a coffee shop….  I can receive phone calls, instant messages and participate or host online web conferences.

Below is the executive summary from the Miercom report.  Download the complete report from here.

Miercom reviewed the latest unified communications offering from Microsoft applying an in depth methodology developed over the last 7 years in studying the development of UC products. Microsoft Lync 2010 now affords Microsoft what it needs to compete and win in the battle for enterprise UC market share.

Significant developments in reliability, security, and a business enabling features make Microsoft Lync a viable option for businesses looking to revolutionize their current communications platform. Components for Microsoft Lync are far less complicated then they were for the preceding product Microsoft Office Communications Server (OCS) 2007 R2. Installation for both Server and Client are now clean and straight forward.

The evaluation of MS Lync included exercise of the client and server side feature set as well as active or delivered tests using test systems for Performance, Resiliency, and Security.

Performance – Microsoft Lync successfully passed voice and video Quality of Experience (QoE) tests under heavily loaded and degraded network conditions. Even with significant jitter and a packet loss percentage in excess of 5% the voice and video quality of the Lync client with High Definition Video was superb. High Definition Video Conferencing was conducted over T1 bandwidth with an average bandwidth of only 142 Kbps needed to maintain the connection. Peak traffic utilization did hit 1.5 Mbps at times when there was full motion in the video sessions.

Resiliency testing on Microsoft Lync Client: To verify the branch resiliency Microsoft Lync 2010 was submitted through a series of tests including failing connections between Lync Client and the Lync Server as well as a failed WAN connection. We found the Lync Client to recover quickly (within seconds) upon restoration of the network connection to the Lync 2010 Server.

We also conducted failover scenarios for simulated branch location using a Survivable Branch Appliance (SBA) from NET the SX 20000. This appliance provided basic voice services to users in the branch during a WAN outage. Microsoft Lync passed resiliency tests for local client as well as branch office deployment.

Security testing for the Microsoft Lync Server revealed a “pass” rating for security testing for Microsoft Lync 2010 (with an appropriate network firewall employed). No inherent vulnerabilities were discovered in Microsoft Lync Server 2010 outright using a battery of vulnerability and protocol analysis tests from leading test and measurement vendors Ixia, Mu Dynamics, and Touchstone.

Bottom Line Microsoft Lync 2010 is a resilient, scalable, feature rich Unified Communications System. Microsoft Lync 2010 should be in the short list of top three to consider for enterprises communications infrastructure upgrades. Quality third party peripherals from Aastra, Polycom and SNOM will help Microsoft achieve more market acceptance at the Enterprise Desktop. Third party hardware such as the survivable branch appliance UX 2000 from NET will enable branch offices the resiliency needed for enterprise communications.
