SUMMARY LSR (Label Switching Router)s in MPLS (Multiprotocol Label Switching) networks map arriving IP flows into some labels on Layer 2 switching fabric and establish LSP (Label Switching Path)s. By using LSPs, LSRs not only transmit IP datagrams fast by cut-through mechanism , but also solve traffic engineering issue to optimize the delay of some IP(More)
The layer 3 switch enables us to transmit IP datagrams fast using the cut-through technique. There are mainly two cases in establishing connections; one is the flow-driven case and the other is the topology-driven one. In this paper, we analyze the cut-through rate, the datagram waiting time and the mis-order rate as performance measure of both cases and(More)

solve traffic engineering issue to optimize the delay of some IP datagram flows. So far, we have analyzed the performance of LSR focusing only on the maximum number of LSPs which can be set on Layer 2. In this paper, we will also consider the band-width allocated to each LSP and analyze the IP datagram transmission delay and the cut-through rate of LSR. We(More)
