Bela Ban commented on JGRP-2098:
--------------------------------
To reduce discovery traffic, an attribute {{only_coord_replies}} (or similar) would be
added to {{Discovery}}. When set, only coordinators (not everyone) reply to a
{{GET_MBRS_REQ}} with a {{GET_MBRS_RSP}}.
In addition, logical name and UUID-address mappings are not sent back with the reply
(making it smaller). At the end of the day, the coord(s) could simply send empty
{{GET_MBR_RSP}} messages, as the sender of those replies will all be coordinators, and
their addresses ({{IpAddressUUIDs}}) can be used to send the JOIN-REQs to.
Discovery: reduce messages when IpAddressUUID is used

Key: JGRP-2098

Project: JGroups
Issue Type: Feature Request
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 4.0
Attachments: LESS_PING.java
Since IpAddressUUID already contains the physical address, we don't need to exchange
physical addresses in the discovery phase.
Investigate whether this leads to reduced messaging in discovery, ie. only the coords
might send a response. Once the new member has the view, it automatically knows the IP
addresses and ports of all members, as the addresses in the view are of type
IpAddressUUID.
Also investigate whether address:logical_name associations should be done in a separate
protocol, e.g. NAMING.
