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.
