In the title of a paper I'm writing, I want to talk about "replication" of servers, but I'm not sure if the object of replication should be written in singular or plural form.
Should I write
Performance evaluation of video servers replication in networks
Performance evaluation of video server replication in networks
My supervisor says it should be the former because several servers are being replicated. But somehow that feels grammatically incorrect to me.
Is there a general rule to support the choice for a singular or plural noun here? Does it depend on how many servers are being replicated (one or several)?
