What are all these acronyms? I read the first paragraph but it really doesn't give much context if you're an outsider.

Here you go - it might not help much, this is a pretty specialized field of network engineering. If you were in a service provider, you were likely aware of this tech otherwise probably not at all.

From my head:

LDP = Label Distribution Protocol

RSVP = ReSource Reservation Protocol

PCE = Path Computation Element

BGP = Border Gateway Protocol

L2VPN = Layer 2 Virtual Private Network

IGP = Interior Gateway Protocol

MPLS = Multi Protocol Label Switching

TE = Traffic Engineering

FRR = Fast ReRoute

SR = Segment Routing

SP = Service Provider
