Abstract
The present invention provides a system and method for transmitting data, including transmitting a first data packet having at least one checksum value across a network, generating a second data packet substantially similar to the first data packet, the second data packet having a checksum value, modifying the checksum value of the second data packet, transmitting the second data packet with the modified checksum value across the network, and assessing a network performance metric based at least in part upon the modified checksum value.
Claims20
A method for transmitting a data packet having a checksum field across a network, comprising:
- appending a checksum value that does not correspond to the content of the data packet to the checksum field;
- and
- transmitting the data packet.
A method for assessing network performance, comprising:
- transmitting a first data packet having a first data in a checksum field across a network;
- generating a second data packet, the second data packet being substantially similar to the first data packet, the second data packet having the first data in the checksum field;
- changing the first data to a second data in the checksum field;
- transmitting the second data packet with the second data across the network;
- and
- assessing a network performance metric based at least in part upon the second data.
A system for transmitting data packets across a network, comprising:
- a sending entity encapsulating a data packet having at first checksum value in a checksum field, the sending entity modifying the first checksum value to a second checksum value and transmitting the data packet across the network.
