Abstract: A device may receive, via a first message, first route information for directing network traffic for a network. The first route information may identify a media access control (MAC) route corresponding to a MAC address associated with a host device connecting to a subnet of the network. The first route information may fail to include Internet protocol (IP)/MAC binding information associated with the host device. The device may transmit a request for IP/MAC binding information associated with the host device. The device may receive a response, to the request for IP/MAC binding information, identifying the IP/MAC binding information. The device may advertise, via a second message, second route information for directing network traffic for the network based on receiving the response identifying the LP/MAC binding information. The second route information may identify the IP/MAC binding information associated with the host device.

Abstract: In some embodiments, a non-transitory processor-readable medium stores code representing instructions configured to cause a processor to receive, from an access switch, a first signal including forwarding state information associated with a first peripheral processing device from a set of peripheral processing devices. The code can further represent instructions configured to cause the processor to receive, from the first peripheral processing device, a second signal including a data packet. The code can further represent instructions configured to cause the processor to send, to a replication engine associated with the set of peripheral processing devices, a third signal such that the replication engine (1) defines a copy of the data packet, which is included within the third signal, and (2) sends, to a second peripheral processing device from the set of peripheral processing devices, a fourth signal including the copy of the data packet.

Abstract: A first device may receive information that identifies a second device. The second device may be connected to the first device or a third device. The second device may be a source of traffic to be received by the first device. The first device may determine whether the second device is local or remote to the first device based on receiving the information. The first device may store first information or second information based on determining whether the second device is local or remote. The first information may identify a route associated with the second device. The second information may identify a single route associated with multiple second devices. The first device may provide the traffic using the first information or the second information after storing the first information or the second information.

Abstract: In some embodiments, a system includes a set of network control entities associated with a distributed multi-stage switch. Each network control entity from the set of network control entities is configured to manage at least one edge device having a set of ports and coupled to the distributed multi-stage switch. Each network control entity from the set of network control entities is associated with a unique set of identifiers. A network control entity from the set of network control entities is configured to assign a unique identifier from its unique set of identifiers to a port from the set of ports of the at least one edge device in response to the network control entity receiving a login request associated with the port.

Abstract: In some embodiments, an apparatus includes a management module configured to assign a unique set of identifiers to each network control entity from a set of network control entities. As a result, a network control entity from the set of network control entities can assign an identifier from its unique set of identifiers to a port in response to that network control entity receiving a login request from the port. The set of network control entities is associated with a distributed multi-stage switch. The management module is also configured to store a zone set database associated with the distributed multi-stage switch. The management module is configured to send an instance of an active zone set stored within the zone set database to each network control entity from the set of network control entities such that each network control entity can enforce the active zone set.
