Multi-packet probes are forwarded from a source to a destination through different paths. The efficiencies of the different paths are then determined by comparing information collected from the probes arriving at the destination. The information can include sequence information such as a sequence number. Packet loss information, such as the ratio of lost packets to sent packets, can be determined based on the sequence information. Alternatively, a histogram of numbers of sequential packets lost can be determined. The information can also include timing information, such as a timestamp, from which relative latency based on the timing information across different paths can be determined. In addition, jitter for each path based on the timing information for that path can also be determined based on the timing information.
