Optimizing transaction traffic on a System on a Chip (SoC) by using procedures such as expanding transactions and consolidating responses at nodes of an interconnect fabric for broadcasts, multi-casts, any-casts, source based routing type transactions, intra-streaming two or more transactions over a stream defined by a paired virtual channel-transaction class, trunking physical resources sharing common logical identifier, and using hashing to select among multiple physical resources sharing a common logical identifier.
