IP throttling
IP throttle engineering is required to control congestion in the DS30 links.
LPPs, SSLPPs, and SNSE-LISs have different throttling requirements, as
described in the following sections.
For more information on datafill for IP throttling, refer to “Chapter 3: EIU
datafill”.
IP throttling for LPP
The LPP incorporates additional throttling control for TCP/IP traffic sent over
DS30s between the MS and LPP.   Throttling protects against incorrectly
engineered LANs from overloading DS30s with errant TCP/IP traffic.
Table 8 shows the recommended traffic values for entry into table IPTHRON.
Adherence to these values ensures adequate bandwidth for the IP router
application and protect against DS30 overload. Refer to “Chapter 3: EIU
datafill” for additional information on table IPTHRON.
