Coolant Leak---What is this part?

[Wyoguy222]

Okay, so I smelled coolant while I was driving couple weeks ago, burnt coolant, and have now found the leak. The coolant is leaking out and dripping onto a hot part of the engine which is giving me the burnt smell. Anyway here is pics of the leak. What is this round thing on top, and what is the part that all these hoses go into? I do not know yet if I need to replace just the hose, or if the part that all the hoses go into is actually cracked.
