As at September 2015, these are the companies that manufacture and market silicon for the networking market. Sold as individual components, these silicon chips are the CPUs of networking performing the actual packet forwarding.
The rise of merchant silicon is due to adoption of the “Foundry Model” for cheap manufacture and is described on Wikipedia
Broadcom has a wide range of silicon for network switching specifically. More generally, Broadcom is a silicon chip design and sales company. Unlike Cisco, its does not make network hardware or software except as needed to support the sales of silicon chips.

Makers of switch silicon for a number of years. Focussed on the mass market for 1G & 10G Ethernet.
Cavium bought Xpliant and now a number of switches are using the Xpliant chipset.
Cisco doesn’t actually manufacture their own silicon and most chip design is outsourced to specialist companies in India. Cisco does still maintain control over a few chips in specific vertical markets like the carrier core for CRS products.
Because of it size and market dominance, the custom silicon that Cisco designs should be regarded as a unique merchant silicon maker for itself.
