EXFO FTB-8510 Ethernet Test Module
Fully integrated test solution for assessing the performance of Ethernet transport networks
Assessing the Performance of Ethernet Services
EXFO’s FTB-8510 Packet Blazer™ brings performance assurance to Ethernet-based services. Its wide range of test functionalities provides all the necessary measurement tools for verifying service-level agreements (SLAs) between service providers and their customers.
The FTB-8510 module tests connectivity in its native format: 10/100/1000Base-T, 1000Base-SX, 1000Base-LX and 1000Base-ZX for LAN-to-LAN services delivered via ATM, frame relay, Next-Generation SONET/SDH, SONET/SDH hybrid multiplexers, switched Ethernet, VLANs, dark fiber, WDM, FTTx systems or other means.
Combined with its rack-mounted manufacturing/R&D-environment counterpart, the IQS-8510 Packet Blazer, the FTB-8510 simplifies and speeds up the deployment of Ethernet services.
Features:
The Internet Engineering Task Force (IETF) has put together a test methodology to address the issues of performance verification at the layer 2 and 3 level. RFC 2544, a “Benchmarking Methodology for Network Interconnect Devices,” specifies the requirements and procedures for testing throughput (performance availability), back-to-back frames (link burstability), frame loss (service integrity) and latency (transmission delay).
When these measurements are performed, they 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 an access technology.
The SLA criteria defined in RFC 2544 can be precisely measured using specialized test instruments. The performance verification is usually done when the installation is completed. The measurements are done out-of-service to make sure that all parameters are controlled.
RFC 2544 Test Suite
The FTB-8510 Packet Blazer can perform the RFC 2544 test suite for 10/100/1000Base-T and optical GigE interfaces at all frame sizes and at full line rate, in order to allow the provider to certify that the circuit is efficient and error-free at 100% utilization.
The Packet Blazer supports automated RFC 2544 testing, which helps ensure repeatable results. Automation also provides ease of use for field technicians by enabling accurate, efficient measurements and results through a clear and simple pass/fail indication. In addition, the Packet Blazer delivers reports that can be given to customers for future reference related to their specific SLAs.
Throughput
Throughput is the maximum rate at which none of the offered frames are dropped by the device under test (DUT) or network under test (NUT). For example, the throughput test can be used to measure the ratelimiting capability of a switch. The throughput is essentially equivalent to the bandwidth.
The throughput test allows vendors to report a single value, which has proven to be useful in the marketplace. Since even the loss of one frame in a data stream can cause significant delays while waiting for the higher level protocols to time out, it is useful to know the actual maximum data rate that the device can support. Measurements should be taken over an assortment of frame sizes. Separate measurements should be made for routed and bridged data in those devices that can support both. If there is a checksum in the received frame, full checksum processing should be done.
Burst (Back-to-Back)
In this test, fixed-length frames are presented at a rate such that there is the minimum legal separation for a given medium between frames over a configurable period of time, starting from an idle state. The back-to-back value is the number of frames in the longest burst that the DUT/NUT will handle without the loss of any frames.
Frame Loss
Frame loss is the percentage of frames that should have been forwarded by a network device under steady state (constant) loads that were not forwarded due to lack of resources. This measurement can be used in reporting the performance of a network device in an overloaded state. This can be a useful indication of how a device would perform under pathological network conditions such as broadcast storms.
Latency
Round-trip latency is the time it takes a bit (cut-through devices) or a frame (store and forward devices) to come back to its starting point. Variability of latency can be a problem. With technologies like voice and video over IP, a variable or long latency can cause significant degradation in quality.
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 their TCP traffic requirements will be supported across the network. The TCP Throughout feature on the Packet Blazer™ offers Ethernet service providers the capability of measuring and validating that the services offered to their customers support the TCP traffic performance they expect.
Efficient Testing Leads to Reliable Performance
BERT over Ethernet
Because the transparent transport of Ethernet services over physical media is becoming common, Ethernet is increasingly carried across a variety of layer 1 media over longer distances. This creates a growing need for the certification of Ethernet transport on a bit-per-bit basis, which can be done using bit-errorrate testing (BERT).
BERT uses a pseudo-random binary sequence (PRBS) encapsulated into an Ethernet frame, making it possible to go from a frame-based error measurement to a bit-error-rate measurement. This provides the bit-per-bit error count accuracy required for the acceptance testing of physical-medium transport systems. BERT over Ethernet should usually be used when Ethernet is carried transparently over layer 1 media, in cases such as:
Data services are making a significant shift towards supporting a variety of applications on the same network. This shift has fuelled the need for quality of service (QoS) testing to ensure the condition and reliability of services. Service providers need to assign different qualities of service to each type of service they offer. By providing the ability to configure different Ethernet and IP QoS parameters such as VLAN ID (802.1Q), VLAN priority (802.1p), VLAN stacking (802.1ad Q-in-Q), ToS and DSCP on multiple streams, the Packet Blazer allows service providers to simulate and qualify different types of applications running over their Ethernet network.
This FTB-8510 Packet Blazer frame analysis feature enables multistream traffic generation and analysis, allowing for the troubleshooting of Ethernet circuits as well as customer-traffic analysis, and error identification. Thanks to its packet jitter measurement capability (RFC 3393), the FTB-8510 lets service providers efficiently benchmark transport networks when it comes to delay-sensitive traffic such as voice and video over IP.
Flexible End-to-End Testing
With the FTB-8510 Packet Blazer, the user can perform end-to-end testing through control of the remote unit via the LAN connection under test. This unique approach gives service providers access to test results for each direction of test, which is essential to fully qualify Ethernet services. It is also possible to perform end-to-end testing by using the Smart Loopback mode where the remote unit will return traffic to the local unit by swapping packet overhead up to layer 4 of the OSI stack.
Ethernet Service Acceptance Testing
The type of testing required for Ethernet service acceptance testing depends on how the service is carried on the network. The opposite figure shows how to test switched transport or transparent physical transport using either RFC 2544 tests or BERT over Ethernet.
All of the tests that are part of the service-level agreement can be performed on either part of the network (end-to-core) or on all of it (end-to-end). For both switched transport and transparent physical transport, end-to-end testing can be performed by using two portable units and testing from one end to the other. Another way of doing this is to send a technician to one site and test, using a second test device that is mounted in the network (e.g., in a central office). This type of testing is useful when two technicians cannot be sent at the same time or when the service provider is providing access to the Internet.
