[mpls-linux-general] How to separate tcp traffic from udp traffic using MPLS

[Carlos V. <car...@ya...>]

Hello,
  
  I´m studying MPLS using the project mpls-linux to mount some testbeds  networks and analyze the Traffic Engineering capabilities of MPLS. Some  papers results show that the TCP traffic is affected by UDP traffic in  the core of MPLS networks.
  
  I´m trying to separate the UDP traffic from the TCP traffic using two  differents LSP´s. I would like to know how can I do that using the  mpls(ip route/iptables with mpls patch) command. I´m know how to create  static LSP´s based on the destination IP to determine the path of  packets, but I don´t know how to determine the path based on the  protocol (tcp/udp).
  
  
  Figure of my network topology:
  
  
                             LSP1(TCP) --->
  
                        _____LSRC_____  
                        /                           \
                       /                             \
  ---LER  A---LSRB                        LSRE----LER F
                        \                             /  
                         \_____LSRD_____/      
   
  
                              LSP2(UDP) --->
  
  
  Thanks for any help.
