Abstract: Some implementations provide a method for managing switches in a data center that includes: (1) establishing a connection from one switch to another switch in the data center, the data center providing a plurality of virtual local area networks (VLANs), each VLAN including at least one Virtual Machine and capable of spanning across more than one of the plurality of switches; (2) provisioning device prefixes for IPv6 addresses, a given device prefix corresponding to a particular VLAN on a particular switch in the data center, the given device prefix included in a host address of a particular virtual machine, the particular virtual machine hosted on a server computer, the sever computer connected to the particular switch without additional intervening switches; (3) configuring a hardware memory to include prefix information and address information; and (4) transferring packets by using the prefix information and the address information.

Abstract: A distributed neighbor discovery module is disclosed where all neighbor discovery operations and functionalities may be distributed to a switch device processor. Each neighbor discovery process on a switch device may run as an individual neighbor discovery router node. There may be no coordination between neighbor discovery processes occurring on different switch devices. All other traffic, including both IPv6 control traffic and data traffic destined to the router may be processed by the central controller processor.
