1. A method for testing a network, comprising:
- a source port unitgenerating a packet addressed to a destination port unit, the packet including a payload comprising a plurality of blocks, each block containing a respective content identifier and respective content data generated using the respective content identifier as a seed for a first random data generator; and
transmitting the packet via the network;
the destination port unitreceiving the packet; and
for each of the plurality of blocks independently;
extracting the respective content identifier and respective received content data from the received packet;
generating respective expected content data using the extracted respective content identifier as a seed for a second random data generator the same as the first random data generator; and
comparing the respective expected content data and the respective received content data.

Abstract
A method and an apparatus for testing a network. A source port unit may generate a packet including a payload, the payload comprising a content identifier and content data in accordance with the content identifier, and transmit the packet via the network. A destination port unit may receive the packet and extract the content identifier and received content data from the received packet. The destination port unit may obtain expected content data in accordance with the extracted content identifier and compare the expected content data and the received content data.

5. An apparatus for testing a network, comprising:
-
a source port unit configured to generate a packet addressed to a destination port unit, the packet including a payload comprising a plurality of blocks, each block containing a respective content identifier and respective content data generated using the respective content identifier as a seed for a first random data generator, and transmit the packet via the network;
whereinthe destination port unit is configured to receive the packet, and for each of the plurality of blocks independently; extract the respective content identifier and respective received content data from the received packet, generate respective expected content data using the extracted respective content identifier as a seed for a second random data generator the same as the first random data generator, and compare the respective expected content data and the respective received content data. - View Dependent Claims (6, 7, 8)
