Selectively refreshing address registration information
First Claim
1. A method of facilitating communications within a processing environment, said method comprising:
- indicating that a virtual interface of the processing environment is to be monitored, the indicating employing a refresh primitive, the refresh primitive comprising a start subcommand to indicate monitoring is to be performed, wherein the indicating further specifies a scope for the monitoring, the scope comprising an interface scope in which inbound traffic and outbound traffic for a connection identifier of the virtual interface are monitored, or an address scope in which inbound traffic and outbound traffic for a particular address of the virtual interface are monitored;
monitoring, for a predetermined amount of time, inbound and outbound traffic on the virtual interface;
determining based on the monitoring whether for a selected component of the virtual interface an inbound frame has been received on the virtual interface but no outbound frame has been transmitted on the virtual interface to an external network device for the predefined amount of time; and
based on determining that the inbound frame has been received on the virtual interface but no outbound frame has been transmitted on the virtual interface for the predefined amount of time, forwarding a generated outbound frame to cause a refresh of address registration information for the virtual interface to ensure that the address registration information is maintained.

Abstract
Facilitating communications within a processing environment. Inbound traffic and outbound traffic on one or more virtual interfaces of the processing environment are monitored for a predefined amount of time. Based on the monitoring, a determination is made as to whether for a selected component of a virtual interface of the one or more virtual interfaces an inbound frame has been received but an outbound frame has not been transmitted for the predetermined amount of time. Based on determining that the inbound frame has been received but the outbound frame has not been transmitted, a generated outbound frame is forwarded to cause address registration information for the virtual interface to be refreshed.
