uNET Service Assurance Remote Probe for IPTV, OTT, VoiP & Internet

The uNET is a palm size probe robot for testing and monitoring Triple-Play services (IPTV, VoIP, Internet) at the customer set top box or the last mile concentrator (ie.GPON mux). Multiple uNET probes can be used throughout the IPTV network on a temporary or permanent basis.Test results are sent to the external FTP server. All tests are performed in a cycle set up by the user.

Features Summary:• Located typically at last mile concentrator ( ie.: GPON OLT)• Acts as a robot to stress test triple play services• IGMP join/leave IPTV streams for a defined time• Measures zap time• Connect optionally as pass thru between customer STB and modem• Checks selected IPTV TR 101290 metrics• OTT streams test for presence, bit rate, download time, HTTP errors• Ping test (number of packets, delay)• HTTP performance test• FTP performance test• WWW accessibility test• DNS (dns status, query time)• DHCP test• VoIP (registration, call, multiple scenario)• Managed by web Element Management System EMS

uNET1 located at customer home and uNET2 located at the GPON OLT

Element Management System (EMS)The Net-EMS (Element Management System) is used to setup and manage a single or multiple uNET probes. The Net-EMS allows viewing and filtering of test results. Test results are stored in the database. Additionally, the Net-EMS provides interface to test events and data to be further processed by the third party management software.The uNET can be optionally used to perform passive IPTV quality monitoring.The diagram above shows the two possible applications of the uNET probe.

EMS server can be located on the customer equipment or on the optional cloud ( ie.: Amazon). EMS allows direct control and monitoring of all uNET probes located locally or globally. If customer NMS is preferred, instead of the EMS, the optional API provides indirect access to the EMS, customized scripting and messaging.

Map view locates the probe on the geospatial map with GPS coordinates. Each probe shows its pass(green), warning(yeallow) and fail(red) status

Availability diagrams show when all active probes are alarm free, when in warning or alarm state

The Alarms/errors over time from the selected probe can be displayed as a graph with each type of alarm/error shown in a different color.

Combined error graph for a specific metric ( Packet Loss in this example) for all probes over time shows multicolor bars. Each color represents different probe.

GENERALAll probes managed via EMS web based serverProbes configuration and tests scripts done in groups or individuallyGroups or individual probes can be configured and started simultaneouslyTests can be completed in the customer defined period time and repeated indefinitelyTest results are stored in the probe memory and archived on the EMS serverThe EMS server provides access to for customers external NMS via API/webservicesCustomers can define their own test scriptsAny of the 2 Ethernet interfaces can selected for management or network connectionCustomer can define fail/success thresholds of each testAvailable encrypted connection to EMSProbes can buffer test results for up to 3 hoursAccess to probes is protected with Firewall that is transparent to testsFirewall configuration is automatedSupport for VLANIP address configuration from EMS

TEST TYPESDHCP Verification - discover, offer, request, ack, releaseDNS Verification – configurable: domain list, timeout, number of trials, return of answer time,

domain address resolutionPING TestWWW Test -webpages list configuration, access, time to load, correct loadingIPTV Test - connect to a selected group of channels, IGMP zap time, stream availability,

packets stats, bitrate ( audio/video), packet errors (CRC)VoIP Test – call any number, call registration, voice test DTMF or 1khz tone
