WAN Traffic Manager (WTM) lets you manage replication traffic across WAN links, reducing network costs. WAN Traffic Manager is installed during the NDS® eDirectoryTM installation and consists of three elements.
WTM resides on each server in the replica ring. Before NDS sends server-to-server traffic, WTM reads a WAN traffic policy and determines whether that traffic will be sent.
These are rules that control the generation of NDS traffic. WAN traffic policies are text stored as an NDS property value on a Server object, a LAN Area object, or both.
This snap-in is the interface to WTM. It lets you create or modify policies, create LAN Area objects, and apply policies to LAN areas or servers. When WTM is installed (as part of the NDS eDirectory installation), the schema includes a LAN Area object and a WAN Traffic Manager page on the Server object.
WAN Traffic Manager (WTM.NLM on NetWare® or WTM.DLM on Windows* NT*) must reside on each server whose traffic you want to control. If a partition's replica ring includes servers on both sides of a wide area link, you should install WAN Traffic Manager on all servers in that replica ring.
IMPORTANT: WAN Traffic Manager is not supported on Linux*, Solaris*, or Tru64 UNIX platforms.
