40 Gb/s and 100 Gb/s Testing: Overview
Internet traffic has grown exponentially as greater numbers of users employ more and more complex types of traffic. The need for bandwidth that handles applications such as IPTV, video, peer-to-peer sharing, and wireless backhaul is becoming readily apparent. Aggregating 10 Gb/s links to handle increased bandwidth not only complicates data center topologies, but is also costly and labor-intensive. It's essential that single, higher-speed links be available in the data center and throughout the Internet. The exponential increase in network traffic requires a leap from 10 Gb/s aggregations to higher-speed Ethernet connections. The next step in data center evolution is 40 Gb/s and 100 Gb/s speed network devices.
Ixia's K2 40 Gb/s and 100 Gb/s modules are the first-to-market test solution for network equipment manufacturers developing 40/100 Gb/s devices, providing full IP layer 2-7 measurement and analysis. Test requirements for 40/100 Gb/s compliant devices range from generating and analyzing the simplest layer 2 data plane traffic all the way up to sophisticated stateful network communication testing, including IPTV, VoIP, video on demand, HDTV, Internet gaming, and multimedia streaming services.
Unframed BERT is supported on 40 Gb/s, 100 Gb/s, and dual speed load modules. This allows individual PCS lane BERT test and error injection over a wide range of PRBS patterns including support for PMD's in IEEE802.3ba draft standard. A full set of BERT-related and Bit Error Ratio (BER) statistics are available.
K2 modules can generate and analyze full 40 Gb/s and 100 Gb/s layer 2-7 line rate traffic, up to 1 million flows per port. Module testing includes such metrics as:
- Real-time latency
- Inter-arrival time
- Packet loss
- Data integrity
- Sequence checking
- Packet capture
K2 modules can measure and analyze the performance of HSE standard-compliant devices at line rate, and are compatible with Ixia's chassis and broad range of 10 Mbps, 100 Mbps, 1 Gb/s, and 10 Gb/s interfaces, allowing real-world, full product testing in a single box.
