bursts of 2,812,500 bytes"

HI EXPERT's!

I Have Read the following on some linke provided by E.Amit in some Post:

In this example, a customer is connected to an Internet service provider (ISP) by a T3 link. The ISP wants to rate limit transmissions from the customer to 15 Mbps of the 45 Mbps. In addition, the customer is allowed to send bursts of 2,812,500 bytes. All packets exceeding this limit are dropped. The following commands are configured on the High-Speed Serial Interface (HSSI) of the ISP connected to the customer:

interface Hssi0/0/0

description 45Mbps to R1

rate-limit input 15000000 2812500 2812500 conform-action transmit exceed-action drop

ip address 200.200.14.250 255.255.255.252

rate-limit output 15000000 2812500 2812500 conform-action transmit exceed-action dr

What does it mean"the customer is allowed to send bursts of 2,812,500 bytes"

That is "rate-limit input average_rate_in_bits normal_burst_in_bytes maximum_burst_in_bytes conform-action transmit exceed-action drop"

Its using Committed Access Rate http://www.cisco.com/en/US/products/sw/iosswrel/ps1820/products_feature_guide09186a00800f4890.html

"rate-limit input 15000000 2812500 2812500 conform-action transmit exceed-action drop". Means the ISP is limiting the customer transmission to 15Mbps in addition the customer is allowed to transmit burst of 2812500 bytes.

"allowed to transmit burst of 2812500 bytes". Means the maximum amount of token the bucket can hold at anytime.
