In this series we introduce an option to transport messages via replication ("replicast") across a selected number of unicast links, instead of relying on the underlying media. This option is used when true broadcast/multicast is not supported by the media, or when the number of true destinations is much smaller than the cluster size. Jon Maloy (4): tipc: add function for checking broadcast support in bearer tipc: add functionality to lookup multicast destination nodes tipc: introduce replicast as transport option for multicast tipc: make replicast a user selectable option include/uapi/linux/tipc.h | 6 +- net/tipc/bcast.c | 200 +++++++++++++++++++++++++++++++++++++++------- net/tipc/bcast.h | 33 +++++++- net/tipc/bearer.c | 15 +++- net/tipc/bearer.h | 8 +- net/tipc/link.c | 12 ++- net/tipc/msg.c | 17 ++++ net/tipc/msg.h | 9 +-- net/tipc/name_table.c | 38 +++++++-- net/tipc/name_table.h | 9 +++ net/tipc/node.c | 27 ++++--- net/tipc/node.h | 4 +- net/tipc/socket.c | 61 ++++++++++---- net/tipc/udp_media.c | 8 +- 14 files changed, 374 insertions(+), 73 deletions(-) -- 2.7.4
