Hello,, I have the next structure and run under mpls perfectly, prefix: 192.168.x.x host_1(LER) <----> host_2(LSR) <----> host_3(LSR) <----> host_4 (LER) on x.x= 0.1 0.2 3.2 3.3 2.3 2.4 I am testing the transfer speed with Iperf. I run server of iperf to host_4,, and in host_1 run the client, my results is the next: On MPLS: [root@uni ~]# iperf -c 192.168.2.4 -F prova.rar -f M -t 30 ------------------------------------------------------------ Client connecting to 192.168.2.4, TCP port 5001 TCP window size: 0.02 MByte (default) ------------------------------------------------------------ [ 4] local 192.168.0.1 port 32772 connected with 192.168.2.4 port 5001 [ 4] 0.0-30.0 sec 29.4 MBytes 0.98 MBytes/sec And I disable mpls, the results is: On IP: [root@uni ~]# iperf -c 192.168.2.4 -F prova.rar -f M -t 30 ------------------------------------------------------------ Client connecting to 192.168.2.4, TCP port 5001 TCP window size: 0.02 MByte (default) ------------------------------------------------------------ [ 4] local 192.168.0.1 port 32780 connected with 192.168.2.4 port 5001 [ 4] 0.0- 8.0 sec 89.1 MBytes 11.1 MBytes/sec It is normal???? I think that on mpls the packets more speed that IP, because the forwading is realise on layer 2 (OSI). What is it???? Something explanation? thank you;; |
