HPREEARB

This operand specifies that the progressive-mode adaptive-rate-based (ARB) flow control algorithm is preferred for the High-Performance Routing (HPR) pipes that traverse the Enterprise Extender (EE) connections that are associated with the connection network that is defined by this group. Progressive mode is used only when the HPR pipe is a single-hop pipe (which includes a single physical hop across a 2-hop EE virtual routing node [VRN]) and the RTP partner supports progressive mode.

For dial-in EE connections that have their associated PUs dynamically created, define this parameter on the model major node (DYNTYPE=EE) PU definition statement. For predefined EE connections, define this parameter on the GROUP or PU definition that is in the switched major node.

Result: If a predefined EE connection is established between two EE endpoints before the VRN connection is established (using the same VIPA addresses), the VRN connection uses the established predefined EE connection. In this case, to control the HPREEARB value associated with the EE VRN, you must specify the HPREEARB operand on the EE PU definition statement (for example, on the switched PU definition).
