A Variable Forwarding Equivalence Class for MPLS Networks
Laiquan Han, Jinkuan Wang, Cuirong Wang, Ling Cai · 2009
With the rapid increasing of the same destination address traffic, traditional forwarding equivalence class (FEC) can not process these traffic efficiently. After elaborating the drawbacks of single FEC, we propose a variable FEC (VFEC) algorithm and evaluate the algorithm using ns2 simulation. VFEC obtains alternative paths and forwards these traffic to multiple available paths. From the thorough analysis of throughput and delay, VFEC obtains a better performance than OSPF, MPLS and MPLS-TE (traffic engineering).
