Presented is an apparatus 200, 300, 400 and methods 500 for detecting any burst error condition on a network 204. The apparatus 200, 300, 400 measures the interval 206, 306, 406 between arriving packets 304, 404 on a network 204 and stores 208 a series of interval measurements for analysis. The apparatus 200, 300, 400 also provides a comparator 212, 322, 324, 426, 428 for determining if a burst error condition 330, 332, 434, 436 occurred. The method 500 shifts the stored interval values 306, 308, 310, 312, 314, 316, 406, 408, 410, 412, 414, 416 based on the arrival 304, 404 of the next packet and its associated interval value and sums 320, 418, 420, 422 a subset of the stored interval values 306, 308, 310, 312, 406, 408, 410, 412 for comparison to a pre-configured period 328, 432 to determine if a burst error condition 332, 436 exists for too few packets. The method 500 provides the sum 318, 418, 420, 422, 424 of a separate subset of stored interval values 308, 310, 312, 314, 316, 406, 408, 410, 412, 414, 416 to another comparator 322, 426 for comparison to a pre-configured period 326, 430 to determine if a burst error condition 330, 434 exists for too many packets. |
