RFC 2544 tests are conducted using Port Pairs. HD-PacketExpert™supports RFC 2544 testing on 3 or 6 “Port Pairs” simultaneously i.e. RFC 2544 testing helps in testing and measuring the aforementioned test parameters. RFC 2544 Testing - Once the BERT process of the switches accomplished, next stage involves the testing of Throughput, Latency (Delay), Packet Loss (at different rates), and also ability to handle bursty traffic etc. HD-PacketExpert™ supports BERT on all 12 or 24 ports.
ETHERNET TESTING EQUIPMENT FULL
BERT testing represents a basic first level testing, making sure that the switch can handle full line rate on all the ports without dropping or corrupting even a single bit. The forwarded traffic from the switch is received by HD-PacketExpert™ and analyzed for Bit Errors, Pattern Sync etc. GL’s HD-PacketExpert™ helps Testing Multiport Switches in 3 Stages:īasic Bit Error Rate Testing (BERT) - In this, Layer2/Layer3/Layer4 frames containing BERT payload of various frame sizes are sent at full line rate to each and every port of the switch. Multiport Ethernet Switch Testing Procedures The Important test procedures are BERT, RFC 2544, Y.1564, and Multi stream UDP and TCP traffic generation and analysis.
GL's High-Density versatile test equipment referred to as HD-PacketExpert™ facilitates the testing of Multiport Ethernet Switches with ease and accuracy. To test such switches requires test equipment that is capable of generating traffic at the rate (24 Gbps or 48 Gbps) and analyze the traffic returned from the switch for errors. High density Gigabit Ethernet Network Switches can have 12 or 24 ports, each supporting full bidirectional 1Giga bits/sec traffic rate, totalling to 24 Gbps or 48 Gbps rate simultaneously on all ports. Welcome to another June, 2017 issue of GL Communications' Newsletter providing information and insights on Testing Multiport Ethernet Switches for Functionality, Throughput and related parameters using GL’s HD-PacketExpert™ a versatile Ethernet based Testing Tool.
