Label space reduction based on LSP multiplexing in MPLS Openflow hybrid network

Recent trends in MPLS networks: technologies, applications and challenges

“…Research on protection is on-going to ensure that networks can promptly react to failures. SDN is also [21] 2018 further improved the load balancing and resource utilisation of the network with SDN Huang et al [23] 2018 overcame the label space reduction problem in MPLS network Guo et al [20] 2017 improved measurement error issues when using the single traffic matrix Mazhin et al [24] 2017 improved network flexibility MPLS-TE Premkumar and Saminadan.

“…However, as the bandwidth and complexity increase, a shortage of MPLS labels will occur. Huang et al [23] claimed that label consumption is expanding rapidly, thereby leading to management complexity, increased operational and capital expenditure and table look-up latency, and reduced performance and scalability. Therefore, the author proposed a method of solving the label space reduction problem in the MPLS network using a hybrid MPLS Open-Flow network scheme via LSP multiplexing.…”
