Abstract
Subnet directed broadcasts for initial program load of network stations are not gated by clients on a slower subnet and changes in the source IP address to accommodate multiple IOPs and load balancing are permitted. A subnet broadcast server transfers a datagram including the load program together with a subnet broadcast identifier and source port identifier to client network stations on a subnet basis. Routers at subnets not matching the subnet broadcast identifier unicast the datagram to a next gateway; and routers at broadcast identifier matching subnets data link layer broadcast unicasted datagrams from intervening subnets to all neighbors on the matching subnet while disregarding forwarding this data link layer broadcast to any adjoining subnets.
