 # Subject
 
+The first description of my internship project was given to me as:
+
+> The project is about benchmarking a new service we're building related to
+> exchange connectivity. It would involve writing a program to generate load on
+> the new service, preparing a test environment and analyzing the performance
+> results. Time permitting might also involve making performance improvements to
+> the services.
+
+To understand this subject, we must start with an explanation of what exchange
+connectivity means at IMC: it is the layer in IMC's architecture that ensures
+the connection between internal trading services and external exchanges' own
+infrastructure and services. It is at this layer that exchange-specific
+protocols are normalised into IMC's own protocol messages, and vice versa.
+
+Here is the list of tasks that I am expected to have accomplished during this
+internship:
+
+* become familiar with the service,
+* write a dummy load generator,
+* benchmark the system under the load,
+* analyze the measurements.
+
+This kind of project is exactly the reason that I was interested in working in
+finance and trading. It is a field that is focused on achieving the highest
+performance possible, because being faster is directly tied with making more
+trades and results in more profits.
+
+Because I expressed this personal interest for working on high performance
+systems and related subjects, I was given this internship project to work on.
