Multi-Stage Application Layer Test Packet Generator For Testing Communication Networks

摘要

Systems and methods are disclosed for generating application layer test packets for testing packet communication networks. The disclosed embodiments utilize multi-stage application layer test packet generator to generate high volumes of network layer test packets in an efficient and cost effective manner. A first co-processor generates tokenized test packets that include non-application layer content and include token values representing desired application layer content. A second co-processor analyzes the token values and replaces the token values with stateful application layer content associated with the token values. Once devices-under-test (DUTs) have received and processed the application layer test packets, the DUTs generate return packets that include stateful application layer content. These return packets are then received and processed by the multi-stage application layer test packet generator.

主权项

1. A method for generating test packets including stateful application layer content, comprising:
generating a tokenized test packet using a first co-processor, the tokenized test packet comprising non-application layer content and a token value representing stateful application layer content; forwarding the tokenized test packet to a second co-processor; receiving the tokenized test packet at the second co-processor; forming an application layer test packet using the second co-processor to replace the token value within the tokenized test packet with stateful application layer content associated with the token value; repeating the generating and forwarding steps at the first co-processor to generate a plurality of tokenized test packets; and repeating the receiving and forming step at the second co-processor to form a plurality of application layer text packets.
