Which cryptographic algorithm is this?

I am investigating a custom network protocol which i believe has som sort of data encryption.

The following happens when a client connects to a server:

Client --- [128 bit  random  key] --> Server
Client <-- [128 bit  random  key] --- Server
Client --- [128 bit (random) key] --> Server
Client <-- [128 bit (random) key] --- Server

Data sent and received is encrypted from now on.

I would like to know what kind of cryptographic implementation i am dealing with.

There is not enough information in your post to answer this question. All you know is that there is some kind of exchange of information taking place in blocks of 128bits.

People here will inevitably post a series of algorithms that this is not (for instance, it's not SSL or a normal DH exchange), but without the contents of the bytes, it's not possible to say for sure what algorithm this is.
