5 NZNOG 2006 – Victoria University Wellington, March 23 rd, 2006 Network test equipment – EXFO PacketBlazer 8510 – wire speed full duplex 10/100/ G – wire speed full duplex 10G LAN/WAN PHY BERT testing at Layer 1 Frame testing at Layer 2 RFC 2544 Performance test suite for network devices Throughput, back-to-back packets, frame loss and latency, jitter Detailed QoS analysis Can extend concept of device testing to (parts of) a network

6 NZNOG 2006 – Victoria University Wellington, March 23 rd, 2006 University of Auckland 10 Gigabit campus ring (1) Requirements: Resilient infrastructure to interconnect eight University of Auckland campus sites Provide multiple 1-Gigabit services at Layer 2 between campuses Solution: Dual-implementation with Summit X450 at six sites within Auckland metropolitan domain Dark fiber between the sites Supports multiple unconstraint 1-Gigabit VLAN services with QoS up to the maximum 10 Gigabit backbone capacity Resiliency via Ethernet Advanced Protection Switching (EAPS) SLA: 99.99% end-to-end throughput SLA: 500 milliseconds maximum round-trip-time SLA: 250 milliseconds maximum packet delay variation

9 NZNOG 2006 – Victoria University Wellington, March 23 rd, 2006 University of Auckland – throughput results 10 Gigabit backbone performance: full line rate for any packet sizes between 128 and 9212 bytes Any single 1-Gigabit loop VLAN: loss free at any packet size 10 loop 1-Gigabit VLAN performance (saturated core, with all services active):

10 NZNOG 2006 – Victoria University Wellington, March 23 rd, 2006 University of Auckland – delay and jitter results Fiber run length 44.7 km – microseconds (RI=1.467) OTD(min) = microseconds Switching, buffering accounts for 39.6 microseconds (15% of total) Per switch latency 3.3 microseconds, inclusive serialization RTTD(64) microseconds at 100% of 1-Gigabit load PDV(64) 1.2 microseconds  Meets SLA requirements comfortably, after adjustment for additional 10 km fiber spur

11 NZNOG 2006 – Victoria University Wellington, March 23 rd, 2006 University of Auckland – latency as a factor of packet size

12 NZNOG 2006 – Victoria University Wellington, March 23 rd, 2006 University of Auckland – EAPS protection switching Measured the impact of a ring break upon site-to-site traffic Worst case scenario – re-routing once around the entire ring Measurements conducted at single site Metric – number of packets lost Worst case timing was measured at 217 milliseconds Typical timing is around milliseconds  Exceeds SLA expectations for sub-second failover

13 NZNOG 2006 – Victoria University Wellington, March 23 rd, 2006 University of Auckland – test summary Installation meets / exceeds original design parameters Network is capable of delivering unconstraint full 1-Gigabit services across the metro domain Fiber spur by far dominates latency (85%) Switching latency is negligible, a few microseconds per packet at most Serialization delay can become the dominating factor with large packet sizes and many hops  Consider the QoS impact when designing applications for either bulk data transfer or sensitive audio/video conferencing applications
