METHODS, SYSTEM AND COMPUTERIZED MEDIUM FOR A TESTING SYSTEM CONNECTION RESILIENCY

The invention relates to a system, a method and a computerized medium for testing a system connection resiliency. According to the invention, the system for testing a network device under testing (DUT) comprises : a device for testing the network equipments, which includes at least one processor; a client and a server, implemented by the device for testing the network equipments and configured to establish a connection by a transmission control protocol (TCP) between client and server and by means of a network device under testing (DUT), where client and server are implemented on one or more processors; a testing controller implemented by the device for testing the network equipments and configured to execute a test script for testing the network device under testing (DUT) by a sequenced data packet exchange by TCP connection between client and server; a resiliency system including a portion on the client part and a portion on the server part, implemented by the device for testing the network equipments, and which is configured to store for each data packet exchanged between client and server, by the TCP connection, an identifier of client sequence for the data packet and an identifier of the server sequence for the data packet and, as a response to an error detected in the TCP connection, to synchronize the client and server for previous data packet, exchanged before the error, using client sequence identifiers and server sequence identifiers and to resume the test script from a data packet following the last data packet exchanged before the error, in the sequenced data packet. Invenţia se referă la un sistem, o metodă şi un suport informatic pentru testarea rezistenţei conexiunii unui sistem. Sistemul de testare a unui dispozitiv de reţea (DUT), conform invenţiei, cuprinde: un dispozitiv de testare a echipamentelor de reţea, ce include cel puţin un procesor; un client şi un server, implementaţi de către dispozitivul de testare a echipamentelor de reţea, şi configuraţi să stabilească o conexiune printr-un protocol de control al transmisiei (TCP) între client şi server, şi prin intermediul dispozitivului de reţea (DUT), în care clientul şi serverul sunt implementaţi pe unul sau mai multe procesoare; un controler de testare implementat de către dispozitivul de testare a echipamentelor de reţea, şi configurat să execute un script de testare pentru a testa dispozitivul de reţea (DUT) printr-un schimb de secvenţe de pachete de date prin conexiunea (TCP) dintre
