Problems solved by technology

In this way, all the traffic is sent to the standard mode FC switch, and then forwarded by the standard mode FC switch, resulting in a large amount of traffic concentrated on the standard mode FC switch, causing network congestion and reducing the system performance of the network.

Embodiment 1

[0034] The embodiment of the present invention provides a traffic exchange method, which is used on the side of the FC switch in NPV mode, such as figure 1 As shown, the method includes the following steps:

[0035] 101. The FC switch in the NPV mode receives the node identification information of the newly registered node and the matching node sent by the FC switch in the standard mode.

[0036] The FC SAN is mainly composed of nodes with HBA cards, that is, hosts or storage devices, and FC Fabric, which includes several standard-mode FC switches and NPV-mode FC switches. When there is a new node to access the FC SAN network, the NPV mode FC switch that is connected through the optical fiber will send a registration request to the standard mode FC switch in the FC Fabric; the standard mode FC switch and the NPV mode FC The switch also has an optical fiber directional connection at the corresponding port, and the standard mode FC switch is the standard mode FC switch to which...

Embodiment 2

[0051] The embodiment of the present invention provides a flow switching method, which is an extension of the first embodiment above. Such as image 3 Said, said method comprises the following steps:

[0052] 301. The standard mode FC switch receives and stores Zone information; the Zone information includes node identification information of all nodes in the same Zone.

[0053] In the FC SAN network, the administrator will pre-define the nodes with traffic exchange requirements as a zone, and all nodes in the zone can perform traffic exchange, and then the administrator will send the newly defined zone as zone information synchronously For all standard mode FC switches in the FC SAN network. The Zone information includes node identification information of all nodes in the same Zone, which means that nodes represented by all node identification information in the Zone information can exchange traffic with each other. The node identification information is commonly used as a...

Abstract

The embodiment of the present invention provides a traffic conversion method, device and system, which relate to the field of communication, and can reduce the forwarding traffic of an FC switch in a standard mode and improve system performance. The NPV mode FC switch receives the node identification information of the new registration node and the matching node sent by the standard mode FC switch, and generates a local forwarding table according to the node identification information, so that the NPV mode FC switch is between the new registration node and the matching node When performing traffic exchange, the exchanged traffic is directly forwarded according to the local forwarding table. The embodiment of the present invention is applied to traffic forwarding in FC SAN.

Description

technical field [0001] The present invention relates to the communication field, in particular to a traffic exchange method, device and system. Background technique [0002] Fiber Channel (Fibre Channel, referred to as: FC) Storage Area Network (Storage Area Network, referred to as: SAN) is mainly composed of nodes with Host Bus Adapter (Host Bus Adapter, referred to as: HBA) card that is the host or storage and Fiber Channel network (FC Fabric ), the FC Fabric includes several standard-mode FC switches, and each standard-mode FC switch has a domain ID (domain ID). After the node is successfully registered on the FC Fabric, the FC Fabric will assign a node port ID (Node Port ID, N_Pord ID for short) to the node. The N_Port ID consists of 24 bits, of which only the upper 8 bits are The domain ID of the standard FC switch is used to distinguish the standard mode FC switch to which the node belongs. Therefore, the number of standard mode FC switches in an FC SAN network should...
