Library /sys$common/syshlp/ncphelp.hlb SET, EXECUTOR, PATH SPLIT POLICY policy  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Specifies the policy for equal cost load splitting of network traffic.
 There are two values for PATH SPLIT POLICY:

  INTERIM      Specifies that all traffic will be split over all
               equal cost paths while forcing individual network
               sessions over the same paths in order to guarantee
               that packets will be received by the destination
               node in the correct order.  The INTERIM value should
               be set if some of the nodes in the network do not
               support out-of-order packet caching.  (VMS version
               4.5 and earlier VMS releases do not support
               out-of-order caching.)

  NORMAL       Specifies that all traffic will be split equally
               over all equal cost paths to a destination node.
               All destination nodes must support out-of-order
               packet caching (supported by DECnet-VAX Version 4.6
               or higher); otherwise, network performance may suffer.
               This is the default value for PATH SPLIT POLICY.
