Abstract: An apparatus includes a memory and a processor operatively coupled to the memory. The processor is configured to partition a set of ports of an optical multiplexer into a set of port groups including a first port group having a first set of ports and a second port group having a second set of ports mutually exclusive from the first set of ports. The processor is configured to associate the first port group with a first router and associate the second port group with a second router. When the optical multiplexer is operatively coupled to the first router and the second router, the first router is operatively coupled to the optical multiplexer via the first set of ports and not the second set of ports, and the second router is operatively coupled to the optical multiplexer via the second set of ports and not the first set of ports.

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.

Abstract: In one embodiment, an apparatus includes a switching policy module configured to define a switching policy associating a Fibre Channel port with a destination Media Access Control (MAC) address. The switching module can be configured to receive a Fibre Channel over Ethernet (FCoE) frame from a network device and send a Fibre Channel frame encapsulated in the FCoE frame to the Fibre Channel port based at least in part on the switching policy and a destination MAC address of the FCoE frame.

Abstract: In some embodiments, an apparatus includes a first network switch configured to be within a Fibre Channel over Ethernet (FCoE) network, which has a set of network switches including the first network switch. The first network switch is configured to receive, from a first network device, a login signal including a proposed logical identifier for the first network device. The first network switch is configured to send, in response to the login signal, a multicast signal including the proposed logical identifier to remaining network switches from the set of network switches. As a result, a second network switch from the set of network switches enforces a zone policy in response to receiving the multicast signal and prior to sending the proposed logical identifier to a second network device.

Abstract: In one embodiment, an apparatus can include a filter module configured to receive multiple Media Access Control (MAC) addresses associated with multiple virtual ports instantiated at a first network device. Each virtual port from the multiple virtual ports can be associated with a MAC address from the multiple MAC addresses. The filter module can be configured to define a filter to be applied to a data frame sent between the first network device and a network switch, the filter being based at least in part on a MAC address prefix included in each MAC address from the plurality of MAC addresses. The MAC address prefix can include an identifier uniquely associated with a second network device at which the filter module operates.
