This read-only value reports the ABR initial cell rate (ICR) negotiated for this SVC, the rate at which the source is allowed to start transmitting before RM-cell feedback has established a sustainable rate. Because starting too high can cause immediate congestion and starting too low wastes available capacity during ramp-up, ICR is a key parameter in how quickly a new ABR connection reaches its fair share of bandwidth. An admin setting up a new ABR SVC for a bursty application might check that cktAbrICR reports a reasonable starting value like 1000 cells/sec rather than an unexpectedly low default that would throttle the connection at startup.
