The Design And Implementation Of Configuration Packet Module In FC Switch

In the SAN network, FC switches, servers, storage equipment, the three entities is common. Which, FC switch is responsible for connecting these servers and storage devices. SAN network in the initialization state, because these entities are not assigned to the FC address, it is not smooth in communication. Here the uniform distribution of this network does not address the state known as instability. Clearly, the network stable state is the network all entities assigned to the unified address, you can communicate. Among them, the address assignment is one of the main functions of the network configuration.SAN in a stable network, access to SAN network packet network via FC SAN switch into. When the FC switch receives the packet, the packet will be forwarded to the SAN network to other switches or server. When the server receives a packet, it will resolve the request packet, and generate storage equipment operating instructions, and the instructions sent to the storage device. Storage device in receiving instruction in these operations will be the implementation of these instructions. If the data is read the instructions, storage devices will be to read the data back to the server, and out of the data through SAN switch network. If the write data command, the server storage device will write the incoming data storage device.SAN directly related to the stability of the whole network is available. Instability in the network, all of the top communications are broken. Network configuration module was responsible for network configuration of FC SAN and try to keep the network is stable. The configuration message module is mainly responsible for the network configuration process for processing packets.Packet processing is mainly straight with the outside world to communicate with the neighbor switch, and compare the information with the local. In this paper, packet processing, analysis of the FC-SW-5 protocol provides network configuration aspects, will be a corresponding demand for their organizations. In addition, the network configuration of the entire process associated with the message processing part of a detailed description and explanation. This article also analyzes the actual project need to be considered, and message processing related technologies and design concepts.Acceptance of the project, the network configuration module can be a complex network environment to complete the network configuration, also configure the message that the normal function of the module. Specific, configure packet inspection module is mainly the outcome of the code and documentation. Among them, the document is divided into requirements documents, design documents outline and detailed design documents.
