The ChoiCe for inTegraTed MulTiserviCe TransporT TesTing With the advent of packet-aware SONET/SDH and OTN add-drop multiplexers—including multiservice transport platforms (MSTPs) and new reconfigurable add-drop multiplexers (ROADMs)—system verification test (SVT) and R&D teams must perform not only traditional SONET/SDH and OTN tests, but also packet-based services verification such as Ethernet, 10 Gigabit Ethernet and Fibre Channel running over the same network elements. This has resulted in a growing demand for multitechnology test solutions that support the stringent testing and troubleshooting...

Optical Transport Network (OTN) Testing OTN as per ITU-T G.709 has recently introduced two new concepts: ODU0 and ODUflex. ODU0 is a new virtual container of 1.25 Gbit/s bandwidth specifically defined for efficiently mapping Gigabit Ethernet services over OTN. As for ODUflex, it is the most efficient sub-wavelength bandwidth management capability for transport line rates of 10 Gbit/s, 40 Gbit/s and upcoming 100 Gbit/s. ODUflex allows providers to interconnect routers in ways that enable efficient bandwidth growth in steps of 1.25 Gbit/s, eliminating the need to allocate a full fixed-rate ODU...

SmartMode: Real-Time Signal Structure Discovery and Monitoring EXFO's IQS-81 20NGE/8130NGE Power Blazer modules support a unique feature called SmartMode. This provides users with full visibility of all high- order (STS/AU) and low-order (VT/TU) mixed mappings within the incoming SONET/SDH test signal. SmartMode automatically discovers the signal structure of the OC-n/STM-n line including mixed mappings and virtual concatenation (VCAT) members. In addition to this in-depth multichannel visibility, SmartMode performs real- time monitoring of all discovered high-order paths and user-selected low-...

ETHERSAM: THE NEW STANDARD IN ETHERNET TESTING Service Configuration Test The service configuration test consists of sequentially testing each service to validate that the service is properly provisioned and that all specific KPIs or SLA parameters are met. A ramp test and a burst test are performed to verify the committed information rate (CIR), excess information rate (EIR), committed burst size (CBS) and excess burst size (EBS). Ramp Test All SLA parameters measured at each step [throughput, frame delay, frame loss, frame-delay variation. OOS. pass/fail result) Burst Test burst sequence (throughput...

rfC 2544 TesTing In cases where the Ethernet service is delivered via switched transport, the RFC 2544 measurements provide a baseline for service providers to define SLAs with their customers. They enable service providers to validate the quality of service (QoS) delivered and can provide them with a tool to create value-added services that can be measured and demonstrated to customers. For example, these tests provide performance statistics and commissioning verification for virtual LANs (VLANs), virtual private networks (VPNs) and transparent LAN services (TLS), all of which use Ethernet as...

TCp ThroughpuT The Internet protocol (IP) and transmission control protocol (TCP) together form the essence of TCP/IP networking. While IP deals with the delivery of packets, TCP provides the integrity and assurance that the data packets transmitted by one host are reliably received at the destination. Applications such as hypertext transfer protocol (HTTP), e-mail or file transfer protocol (FTP) depend on TCP as their delivery assurance mechanism within networks. Customers deploying such applications expect not only physical and link level SLAs from their service providers, but assurance that...

Login Testing Most new-generation transport devices (xWDM or SONET/SDH MUX) supporting Fibre Channel are no longer fully transparent; they also have increased built-in intelligence, acting more as Fibre-Channel switches. With switch fabric login ability, the IQS-8120NGE/8130NGE modules support connections to a remote location through a fabric or semi-transparent networks. The login process not only permits the unit to connect through a fabric, but it also exchanges some of the basic port characteristics (such as buffer-to-buffer credit and class of service) in order to efficiently transport the...
