Telchemy ePM

• Improves efficiency: Router-integrated network performance management and monitoring can supplement or replace stand-alone appliances, eliminating the operational expenses needed to qualify, integrate, spare, maintain power, and cool appliances.
• Provides comprehensive IP troubleshooting: Ensures service quality for a wide range of IP services, including VoIP.
• Improves the operations environment with pre-deployment testing of application behavior, post-deployment performance measurement, MOS scores for VoIP-specific SLAs, and statistics collection for historical data analysis, and rapid problem identification and isolation with real-time reporting of test results, visualization of data, fault correlation, and analysis.
• Ensures quality: A Juniper validated and supported network application.

TePM is supported on the M120 and M320 via the Multiservice PIC (MS-PIC 400 and MS-PIC 500), and MS-DPC for the MX960, MX480, and MX240.

Specifications:

VoIP test capabilities support VoIP test call generation to other TePM agents and standard-based Session Initiation Protocol (SIP) endpoints.

• RTP stream generation according to RFC3550
• RTCP SR/RR (RFC3550) and RTCP XR VoIP (RFC3611) metrics
• 10, 20, 30 ms packet intervals (up to100 ms for some tests)
• Selectable pre-encoded payloads for G.711, G.729A codecs
• "Thin call" option with zero length payload
• Call setup using SIP signaling
• Measurement of incoming RTP stream
• Insertion of packet impairments into outgoing stream, including independent and bursty packet loss
• Generation of multiple concurrent streams
• Configurable minimum and maximum call duration and inter-call time interval
• Integrated UDP traceroute function to detect route followed by call

Network application test capabilities support generation of synthetic network application transactions.

• Dynamic Host Configuration Protocol (DHCP) availability and response time tests
• Domain Name System (DNS) availability and response time tests
• HTTP availability and response time tests
• Point of presence (POP) availability and response time tests
• Simple Mail Transfer Protocol (SMTP) availability and response time tests
• Measurements and reports on the availability and performance at each layer associated with the specific network application (i.e., IP, UDP/TCP, session, transaction)
• Identification of the layer at which performance failure occurs

Network test capabilities for testing against IP addressable devices such as a server or router.

• Ping
• Traceroute

Hop-by-hop tests, with congestion detection, duplex mismatch detection, and available bandwidth estimation results reported on a per hop basis.
