Brocade Communications Systems | Date: 2017-01-11

Techniques for performing intelligent load balancer selection in a multi-load balancer environment are provided. In one embodiment, a computer system can generate a user interface for deploying a virtual IP address (VIP) on a load balancer in a network environment, where the network environment includes a plurality of load balancers, and where the user interface presents a plurality of criteria for selecting one of the plurality of load balancers. The computer system can further receive, from a user, a selection of one or more of the plurality of criteria, and can collect, from each load balancer in the plurality of load balancers, statistics that are relevant to the one or more criteria. The computer system can then select a load balancer from among the plurality of load balancers based on the one or more criteria and the collected statistics.

One embodiment of the present invention provides a switch in a network of interconnected switches. The switch includes a storage device, a hardware management apparatus, and a layer-2 management apparatus. The storage device stores a forwarding table, which includes an entry comprising a MAC address and an egress port for the MAC address. The hardware management apparatus determines whether a destination MAC address of a frame is present in a hardware table in memory of the switch. The layer-2 management apparatus, in response to a determination that the destination MAC address is not present in the hardware table, looks up a first entry comprising the destination MAC address in the forwarding table, and creates a second entry comprising the destination MAC address in the hardware table based on the first entry.

A Layer 2 network switch is partitionable into a plurality of switch fabrics. The single-chassis switch is partitionable into a plurality of logical switches, each associated with one of the virtual fabrics. The logical switches behave as complete and self-contained switches. A logical switch fabric can span multiple single-chassis switch chassis. Logical switches are connected by inter-switch links that can be either dedicated single-chassis links or logical links. An extended inter-switch link can be used to transport traffic for one or more logical inter-switch links. Physical ports of the chassis are assigned to logical switches and are managed by the logical switch. Legacy switches that are not partitionable into logical switches can serve as transit switches between two logical switches.

One embodiment of the present invention provides a switch. The switch comprises one or more ports and a link management module. The link management module operates a first aggregate link group as an active aggregate link group of a protected virtual link aggregation. This protected virtual link aggregation operates as a single logical channel. An aggregate link group comprises a plurality of logically aggregated links. The first aggregate link group, which represents the logical channel, comprises at least a first port of the one or more ports of the switch. The link management module also operates a second aggregate link group of the protected virtual link aggregation as a standby for the first aggregate link group. The second aggregate link group comprises at least a second port of the one or more ports of the switch. Forwarding is enabled via the first port and disabled via the second port.

One embodiment of the present invention provides a switch which comprises one or more ports adapted to receive packets. The switch is a member of a network of interconnected switches, and also comprises a path monitoring apparatus adapted to: in response to a control packet associated with a session within a predetermined time interval, set a receive indicator for the switch to an active state; and in response to absence of the control packet associated with the session within the predetermined time interval, set the receive indicator for the switch to an inactive state. The path monitoring apparatus is also adapted to set a path state associated with the session based on the receive indicators for the switch and other member switches. The switch also comprises a broadcast apparatus adapted to broadcast at least the receive indicator for the switch to the other member switches.

A switch that facilitates remote port mirroring is described. The switch can include an encapsulation mechanism and a forwarding mechanism. The encapsulation mechanism can be configured to encapsulate a copy of a first packet in a second packet, thereby preserving header information (e.g., a VLAN identifier and/or a TRILL header) of the first packet. The forwarding mechanism can be configured to forward the first packet using header information of the first packet, and forward the second packet using header information of the second packet. The second packet can be received at a destination switch which extracts the first packet from the second packet, and sends the first packet on a port which is coupled to a network analyzer.

Systems for performing inline wire speed data deduplication are described herein. Some embodiments include a device for inline data deduplication that includes one or more input ports for receiving an input data stream containing duplicates, one or more output ports for providing a data deduplicated output data stream, and an inline data deduplication engine coupled to said one or more input ports and said one or more output ports to process input data containing duplicates into output data which is data deduplicated, said inline data deduplication engine having an inline data deduplication bandwidth of at least 4 Gigabytes per second.

One embodiment of the present invention provides a switch. The switch includes a gateway subgroup module, a tunnel management module, and a packet processor. The gateway subgroup module operates the switch in conjunction with a remote switch to form a gateway subgroup. The switch and the remote switch actively operate as tunnel gateways. The tunnel management module maintains a data structure indicating whether a tunnel source subnet is associated with the gateway subgroup. The packet processor decapsulates a tunnel-encapsulated packet in response to a tunnel source subnet of the tunnel-encapsulated packet being associated with the gateway subgroup.

The FC port state machine enhanced by determining if various lanes are configured to be operated in 128 Gbps mode by operating as parallel lanes as indicated by using a reserved bit in a link training field. If so and if all of the ports are 32 Gbps ports and pass training, then four lanes can be combined to form a 128 Gbps link. If the ports are configured for 128 Gbps only operation and at least one lane does not negotiate to 32 Gbps or fails training, the link is not activated and none of the lanes are activated. If the ports are configured to do either 128 Gbps or independent operation and at least one lane cannot operate at 128 Gbps, then the lanes operate independently at the negotiated and trained speed. If the lanes are configured for only independent operation the transceiver develops independent links as negotiated.

The PCS and FEC layers are combined into a single layer and the number of lanes is set at four lanes. The combination allows removal of many modules as compared to a serial arrangement of a PCS layer and an FEC layer. The reduction in the number of lanes, as compared to 100 Gbps Ethernet, provides a further simplification or cost reduction by further reducing the needed gates of an ASIC to perform the functions. Changing the lanes in the FEC layer necessitates changing the alignment marker structure. In the preferred embodiment a lane zero marker is used as the first alignment marker in each lane to allow rapid sync. A second alignment marker indicating the particular lane follows the first alignment marker.
