Testing was conducted via the DevConnect Program at the Avaya Solution and Interoperability Test Lab. 1 of 29

2 1. Introduction Streamcore StreamGroomers regulate the traffic exchanged between LAN and WAN networks. Traffic is monitored and controlled according to network, application, VoIP and video rules specified by the administrator. Each appliance is seamlessly integrated inline between the LAN and the router and has an automatic bypass feature to ensure transparency in the rare event of a malfunction. Streamcore StreamGroomers are administered by a dedicated port. Several models are available to meet all networking needs either for datacentres and branch offices, depending on the data rates and traffic volumes to be processed. 2. General Test Approach and Test Results The test environment comprises of two locations: the main office or datacentre and a branch office or remote site. The equipments from Streamcore for this compliance test consist of one StreamGroomer Manager (SGM) and two StreamGroomer SG250 s (SG). The SG s lay between the LAN and WAN on each site. Each SG is configured and monitored from the SGM. The SGM is accessed through a HTTP session from any machine on the network and all real time statistics from the SG devices are observed via this one HTTP session to the SGM. Testing for the compliance of StreamGroomer involves observation of the Avaya communications over the network showing loss of quality and other related quality of service (QoS) issues as in most normal network infrastructures that have limited bandwidth. A WAN simulator was used to adjust the size of the bandwidth on the WAN in order to demonstrate such network restrictions and the effects on VoIP and video calls. This WAN simulator was supplied by Streamcore to limit the data rate for all flows at 1 Mbps, while bandwidth hungry traffic such as file transfer was exchanged over the network to compete with VoIP and video calls. The approach of testing was to demonstrate that when such restrictions on bandwidth were in place, the SG would monitor degradations through passive measurements, and improve the QoS on VoIP and more evidently video calls by activating traffic shaping/bandwidth management. The second objective was to ensure that in no way it affected the normal flow of traffic other than to prioritize certain traffic on the network and to improve RTP flow for voice and video calls. 2 of 29

3 2.1. Interoperability Compliance Testing The compliance testing consisted of the following: 1. Basic component connectivity tests to ensure all devices are visible on the network. 2. Observation of the network when the SG250 s were added only in by-pass mode. 3. Observation through monitoring on the SGM of VoIP and video calls with no traffic or bandwidth restrictions on the network. 4. Observation through monitoring on the SGM of VoIP and video calls with a bandwidth restriction of 2Mbps on the WAN and various simulated traffic scenarios on the network. 5. Using the SG to control the WAN traffic and observing the resulting VoIP and video quality improvements both visually and through monitoring on the SGM. 6. Generating reports from the SGM Test Results All tests passed successfully. Observation of the real-time data coming from the SGM corresponded to what was experienced visually as expected Support For more information on Streamcore and product support visit Streamcore Immeuble Avant-Seine 11-15, Quai de Dion Bouton Puteaux France Tél. : +33 (0) Fax : +33 (0) Support: support@streamcore.com 3 of 29

21 7. Verification Steps Verify that both video and voice calls can be made correctly and that the monitoring of the bandwidth used is in real-time. To display a change in real-time statistics the codec of a voice call on the Avaya Communication Manager was changed from G.729A to G.711A and observed the codec displayed on the SGM Verification of User Registration Log into System Manager to check and see that sets are registered correctly. In Session Manager, click on System Status and User Registrations highlighted below. 21 of 29

22 Under User Registrations a list of users that are registered to Session Manager are listed. See the example of user 3000, which is an Avaya 9620 IP Telephone user on the Remote1 site Verification of Real-Time Statistics on the StreamGroomer Manager Go to Services (top left of screen). Open the desired site (DataCenter) and click on Access link DataCenter. Click on Real-time stats and Breakdown to view on a global level what bandwidth is being used. 22 of 29

23 Clicking on the VoIP/Video G.711 along the left hand menu will show information specific to this codec. Clicking on the Troubleshooting tab and VoIP/Video Communication as show below will give a session by session view for each conversation and all network information pertaining to that call. 23 of 29

24 Check on Communication Manager to see what codec is configured. Type in display ip codecset x where x is the codec set in Section 5.1. Change the codec set to only include G.729A using the command change ip-codec-set as shown below. change ip-codec-set 1 Page 1 of 2 Codec Set: 1 IP Codec Set Audio Silence Frames Packet Codec Suppression Per Pkt Size(ms) 1: G K : G K n : G.729A n 2 20 Note the real-time statistics show the G.729A calls only and no other codec. Note the bandwidth used for a G.729A call, including the header and footer, is only 24K. Change the codec set on Communication Manager to include G.711 only and observe the realtime statistics. The total bandwidth now for two simultaneous calls is over 160K. 24 of 29

25 7.3. Monitoring Video Calls with Data Disruption With high data traffic across the network there is a large amount of latency and jitter as well as RTP packet loss for a video call on the Main Site as shown below. Checking the same video call for the remote site will show similar loss depending on which direction the network traffic is most prevalent. 25 of 29

26 Checking the same video call for the remote site will show similar loss on the video RTP flow Monitoring Video with network control activated Observe the figures for Network Loss RTP % and Discard rate % below is now 0 and the latency is reduced. This is also visually observed in the quality of the video calls made there is no missing picture or degradation after control is switched on. 26 of 29

27 7.5. Verification of the reporting For the period scheduled, the PDF report shows a global view of each rules selected with different indicators (rate, latency, loss, discard rate, jitter,etc). 27 of 29

28 8. Conclusion All tests passed with no failures. The addition of the SG s to the network did not impact on the performance of the network. Calls from Avaya Aura Communication Manager R6.0.1 and Avaya Aura Session Manager R6.1 behaved as before the addition of Streamcore StreamGroomers. Monitoring of the SG s through the SGM showed the expected statistics for the various calls that were made. When the network was restricted and QoS was affected the SG was able to improve the QoS on the network and this was shown in the statistics on the SGM as well as a visual observation of the video calls in progress. 9.
