Ethernet IQ2 PIC RTT Delay Buffer Values
The following table shows the round-trip time (RTT) delay buffer values for IQ2 PICs, which are nonstandard and vary by PIC type and direction. The values are rounded up slightly to account for oversubscription.
Table 1: RTT Delay Buffers for IQ2 PICs
IQ2 PIC Type | Ingress Buffer (ms) | Egress Buffer (ms) |
|---|---|---|
4–port Gigabit Ethernet (Type 1) | 200 | 300 |
8–port Gigabit Ethernet (Type 2) | 175 | 200 |
8–port Gigabit Ethernet (Type 3) | 35 | 225 |
1–port 10–Gigabit Ethernet (Type 3) | 25 | 190 |
