Data processing method, device and system

Abstract

The invention provides a data processing method, device and system. As fiber channel identification of fiber channel nodes and medium access control addresses in the Ethernet are configured by address distributing equipment located in the Ethernet according to an IP broadcast protocol, when the first fiber channel code in the Ethernet requires communication interaction with the target node, a broadcast message comprising source fiber channel identification of the first fiber channel node and target fiber channel identification of the target node is sent, and when the first fiber channel code receives a response message comprising the first medium access control address, corresponding to the target fiber channel identification of the target node and being returned back by the second fiber channel node in the Ethernet, information to be transmitted is directly sent to the target node according to the first medium access control address. Accordingly, when the fiber channel nodes in the Ethernet conduct communication interaction, data forwarding is conducted not through an FCF, processing sources are saved, and data transmission efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a data processing method, device, and system. Background technique [0002] The Fiber Channel over Ethernet (FCoE) technical standard can map Fiber Channel to Ethernet, so that Fiber Channel requests and data from server-storage devices can be transmitted through Ethernet connections. [0003] Since FCoE is a two-layer encapsulation protocol, it essentially uses the Ethernet physical transmission protocol to transmit optical fiber network data. Therefore, in the prior art, all newly configured Fiber Channel nodes in the Ethernet are provided by a Fiber Channel proxy device (Fibre Channel) Channel Forwarder (FCF) allocates Fiber Channel identifiers and media access control addresses according to the Fiber Channel over Ethernet Initialization Protocol (FCoE Initialization Protocol, FIP), figure 1 For the structural diagram of the existing data...

[0003] Since FCoE is a two-layer encapsulation protocol, it essentially uses the Ethernet physical transmission protocol to transmit optical fiber network data. Therefore, in the prior art, all newly configured Fiber Channel nodes in the Ethernet are provided by a Fiber Channel proxy device (Fibre Channel) Channel Forwarder (FCF) allocates Fiber Channel identifiers and media access control addresses according to the Fiber Channel over Ethernet Initialization Protocol (FCoE Initialization Protocol, FIP), figure 1 For the structural diagram of the existing data processing system, see figure 1 It can be seen that if the target node to be accessed by the newly configured Fiber Channel first node in the Ethernet is still located in the Fiber Channel second node in the Ethernet, it is also necessary to first access the FCF to obtain the media access control address of the target node before communicating with the target node. Nodes communicate and interact. Therefore, when a large amount of access data increases, it is easy to cause excessive FCF pressure, processing bottlenecks, and reducing data transmission efficiency.
