|Data type||Range||Default value|
|REG_DWORD||0x1 - 0xFFFFFFFE packet headers||0x32 (50)|
Determines how many IP packet headers TCP allocates to the router packet queue when the system starts.
When all of the IP packet headers allocated at startup are in use, the router begins to discard packets at random from the queue. The value of this entry is used only when routing is enabled and headers are allocated.
The value of this entry should be at least as large as the value of the ForwardBufferMemory entry divided by the maximum IP data size of the networks connected to the router. However, it should be no larger than the value of ForwardBufferMemory divided by 256, because at least 256 bytes of forward buffer memory are used for each packet. The optimal number of forward packets for a given ForwardBufferMemory size depends on the type of traffic carried on the network and is somewhere between these two values.
Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
