    Hi Ganpat,

    From the first bullet CIR = 6000000 bps

    As the question says: "Allow for a commited burst of 1/8 of this rate an no excess burst"

    Bc (bits) = 1/8 * CIR = 6000000/8 = 750000
    Bc (bytes) = 750000/8
    Bc (bytes) = 93750

    To disable excess burst in CAR, Be must be equal to Bc, then:

    Be (bytes) = 93750


    Regards,
    Ovesnel
