Claim:
A method, comprising: receiving first data indicative of a plurality of errors in a multicast data stream that is propagating through a network; receiving second data indicative of a plurality of links in the network; determining by a computer a path through which the multicast data stream propagates, the path comprising at least some of the links; determining by the computer, for each of the links in the path, a cumulative number of the errors in the multicast data stream that occur along the respective link over a plurality of overlapping periods of time; determining by the computer, based upon the determined cumulative number of errors in each of the links in the path, a cumulative number of the errors in the multicast data stream that occur along the path over each of the periods of time; and displaying, by a display device, a user interface that comprises: a graphical representation of the links coupled together in the path, an indication, for each of the graphically represented links, of the determined cumulative number of errors that occur along the respective link for each of the periods of time, and an indication of the determined cumulative number of errors that occur along the path for each of the periods of time.
