Causes and Correlation of Network Impairments — Learn how ARP cache timeouts and leaky VLANS (among other things) create delay, loss, jitter, and more to packets as they traverse the network.
Instance IDs in SNMP — Understanding scalar and columnar objects and the concept of multiple instances of one object.
Limitations of ICMP Echo for network measurement — ICMP Echo, more commonly known as "ping" is not a valid tool for measuring network distance or performance.
