Is there a way to let your Live stream buffer a few seconds, so if you have a network drop the stream won't lag or drop?

Is there a way to let your Live stream buffer a few seconds, so if you have a network drop the stream won't lag or drop? I'm streaming for 2-3 hours at a time, and having every now and then a network drop. I worked with my ISP to check for a solution, they sugested a buffer, due to the drops not being more than 3 seconds, is there a way to add such a buffer on OBS?
