Product Overview
The RFC-2544 with VLAN Network Device Benchmark Test Package is an essential tool enabling network testers to measure the performance of Layer 2 and Layer 3 switch-es and the networks on which they will be deployed. A component of the Spirent TestCenter, the test package provides a framework
to test modern routing features within the guidelines of well-established standards.
This product provides pre-pro-grammed tests per the IETF RFC-2544, Benchmarking Methodology for Network
Interconnect Devices, which is the standard for initial perform-ance testing of L2/L3 switches.With this test package you can quickly obtain baselines of behavior on existing network devices and reveal the effects of newer technologies as they are incrementally introduced.
The product’s capabilities extend beyond RFC-2544, sup-porting the latest technologies, all within a unique frame-work for better troubleshooting and customization of controls than found in legacy solutions.
Applications
This test package helps Spirent TestCenter customers to evaluate key performance parameters of L2/L3 switches under typical or extreme traffic load conditions for min-utes, hours, and days. It can emulate unicast traffic across a device or network under test, performing tasks such as regression testing following firmware changes and comparative analysis of switches and routers. It can perform standards-based tests with a large number of uniquely trackable traffic streams to verify scalability before a network goes live.
In preparation for using VLANs, DiffServ, jumbo frames or IPv6, the RFC-2544 with VLAN Network Device Benchmark Test Package can assess network performance impact,and it can make measurements on data plane traffic with combined control plane activity such as BGP and
Multicast. The product goes beyond the level of analysis described in RFC-2544.
Benefits
s
Ensure that test results baseline according to the RFC and see the effects of newer technologies as they are incrementally introduced
s
Run RFC-2544 tests over VLAN-based topologies
s
Test with jumbo frames to verify whether or not the bulk transfer capacity of a network is truly low-latency and wire-rate. These constraints are particularly important for cluster computing
s Evaluate the effectiveness of QoS algorithms s
Automate testing on multiple operating systems
g e t i t d o n e f a s t e r w i t h
Spirent TestCenter
s Integrated RFC test methodology
s Transmit 32,767 unique streams per port
s
Introduce VLANs, jumbo frames, QoS, and IPv6into test scenario for comparison to IPv4 test baselines
s Wizards for large and complex traffic creation s Finite control of traffic streams
s Enhanced results with complete per-stream results analysis
s
Integrated automation
2RFC-2544 with VLAN Network Device Benchmark Test Package
s Improve understanding between developer
and QA performance tester by using
standard benchmarks
s Obtain a rich set of results that provide
significant insight into performance
degradation—in real-time and after the
test has completed
s Test large switches in a small, cost-effective
footprint
s Reduce time-to-test by making tests easier
to configure, faster to run, more
interoperable, and easier to interpret
s Facilitates testing of IPv6 transition
scenarios with native IPv6 support
s Uncover potential issues with realistic
traffic configuration, integrated capture,
decode, and statistics
Key Features
s RFC testing of L2/L3 devices per RFC-2544
s Support for technologies beyond the RFC:
VLANs, DiffServ, jumbo frames and IPv6
s Key metrics beyond the RFC, such as
per-stream statistics
s A single user interface for RFC testing com-
bined with bridging and routing protocols
s Wizards provide easy test setup of IPv4 and
IPv4 traffic for complex test configurations
s Finite control of frame content via the
Spirent Packet Generator and Analyzer
s Large number of streams allows simulation
of thousands of logical network users
Test Results
The RFC-2544 with VLAN Network Device
Benchmark Test Package provides both
real-time results and final test results using
spreadsheets and graphical formats. These
results can be exported in comma separated
value (.CSV) file format or HTML for spread-
sheet or browser-based analysis and reporting.
s The test package provides enhanced
results with complete per stream results
analysis. Post-test results are provided on a
port and on an individual stream level
s Integrated real time counters help identify
gross failure conditions as they happen,
such as packets lost and misdirected, ARP
failures, and intermittent frame check
sequence errors
s Integrated capture feature allows capturing
of data as the primary test executes
s Test results reported in terms of fps, Mbps,
Kbps, bps and % of line rate for easy com-
parison to the same units used in the
transmit configuration
