Abstract:
1. A method, comprising: detecting a topology change on a link in a network; determining a first zone group that includes the topology change; identifying a second zone group in the network that is permitted to access a device on said link; determining an address of an expander that has the second zone group permitted to access the device on said link, wherein determining the address comprises accessing a route table using the second zone group that is identified by a permission table, wherein the permission table identifies which zone groups are permitted to access devices on links for other zone groups, wherein said route table specifies expander addresses associated with each zone group; and generating an expander-targeted zoned broadcast command to report the topology change in the network, said expander-targeted zoned broadcast command having, as a destination address, the address of the expander determined to have the second zone group permitted to access the device on said link.
