Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0028] An access control list (ACL)-based message forwarding method is proposed in the embodiment of the present invention, which can realize the forwarding of FCoE messages by using ACL entries instead of dedicated FC forwarding entries. The method is applied to a device, which can be used for message exchange between the FC network and the Ethernet network.

[0029] In the embodiment of the present invention, a one-to-one virtual local area network identifier (VLANID) is specified for each virtualized storage area network identifier (VSANID), and the VLANID specified for the VSANID is used instead of the VSANID as the key when delivering the Fiber Channel forwarding entry Generate ACL entries.

[0030] The specific implementation is ...

Abstract

The invention discloses a message transmitting method on the basis of an access control list. The message transmitting method includes packaging FC (fiber channel) messages to be FCoE (fiber channel over Ethernet) messages when receiving the FC messages; analyzing the FCoE messages to acquire VLAN (virtual local area network) ID (identity) and D_ID; searching corresponding output port and message updating information in the ACL (access control list) according the VLAN ID and the D_ID, and updating the FCoE messages according to the searched message updating information; if the searched output port is an FC port, unpackaging the updated FCoE messages to be the FC messages, and transmitting from the searched output port; and if the searched output port is not the FC port, transmitting the updated FCoE messages from the searched output port. On the basis of the same concept, the invention further provides message transmitting equipment which can support the FC port and realize transmission of the FCoE messages.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message forwarding method and device based on an access control list. Background technique [0002] Today's data centers typically run two separate networks: an Ethernet network (LAN) for client-to-server and server-to-server communications; and a Fiber Channel storage area network (SAN) for server and storage communications . The coexistence of the two types of networks greatly increases the network complexity and various costs of the data center, and the scalability is poor. The Fiber Channel over Ethernet (FCoE) protocol can well solve the above problems. Its principle is to carry Fiber Channel protocol (FC) packets on the Ethernet, allowing the service traffic of the SAN network to be transmitted on the Ethernet. Using switches supporting FCoE to build a data center network can replace the current dual-network structure with Ethernet, thereby effectiv...
