High real-time and high reliability communication networks are the foundation of smart grid communication. The communication network cannot be isolated from the related communication technologies. This study proposes a multi-protocol label switching (MPLS)-based smart grid communication scheme as a reference value for more scientific and efficient smart grid communication technology design. MPLS technology is featured by the advantages of traditional internet protocol (IP) and asynchronous transfer mode (ATM) technology as well as flexibility and high-speed switching capability, which can reduce the network cost and ensure the quality of information service for different real-time needs. An efficient multipath routing artificial spider web topology is also introduced after MPLS analysis. Finally, how the MPLS average bandwidth routing algorithm affects smart grid communication technologies is examined. The findings demonstrate that load balancing on each communication channel is achieved when MPLS technology is implemented in the network environment. With regard to jitter and delay, it performs better than the OSPF routing algorithm. After MPLS is introduced, the throughput on the wide-area monitoring server is stable as the LSP1 throughput increases from 5×107 s to 10×107 s, and the intelligent network communication is essentially unaffected. This technological advancement holds significant practical implications for enhancing the smart grid’s communication effectiveness and guaranteeing the power grid’s steady operation.
