In thispaper, we perform a comparative research on various tunneling techniques including MPLS, IPSec, GRE, IP-in-IP,and L2TP. We can conclude the evolutive trend of utilizing tunneling techniques in VPN by analyzing them syntheti-cally. Especially, it will probably become a key problem that guarantees the compatibility and interoperability be-tween MPLS, IPSec and L2TP.展开更多
