In this paper, we introduce the first implementation of the Delay Based Routing Protocol (DBRP), a flexible distance vector routing protocol with a delay based metric, that supports authentication and encryption. Besides carrying routing information, DBRP also transports information for common services such as the IP addresses of the DNS servers. It operates over the data link layer and is centered on Type-Length-Value (TLV) tuples, which make it easy to extend to other existing or future network protocols. Our implementation is developed in C++, and offers a GUI developed in Qt for easy configuration. We validate this first implementation under several test scenarios and have obtained very encouraging results. Additionally, the exploratory study of our application that we conduce with a group of students indicates that the protocol can be easily understood and configured through the GUI.

In this paper we propose a new routing protocol called Delay Based Routing Protocol (DBRP). DBRP is a flexible distance vector routing protocol with a metric based on delay. It natively supports IPv4 and IPv6, and can also carry information for common services such as the IP addresses of the DNS servers. This last feature makes it unique, since existing routing protocols only transport routing information. DBRP also has support for authentication and encryption. It operates over the data link layer and is based on Type-Length-Value (TLV) tuples; therefore, DBRP can be easily extended to other existing or future network protocols. Additionally, by defined new TLV tuples, other common services (e.g., NTP, NIS, NIS+, SIP, log, and printer servers), as well as other hash and encryption algorithms can be simply added to our protocol.

We propose a new sequence-based algorithm to track and find solutions to the Diophantine equation $X^3+Y^3+Z^3=k$, for a fixed integer $k > 0$. &nbsp
