Problems solved by technology

However, for most applications, the method described in this document cannot be used because it is not based on grid computing itself
On the other hand, because its implementation uses grid middleware, the overhead is very high, so it can only be used for large file transfers, not suitable for medium-sized file transfers

Embodiment Construction

[0021] In this embodiment, a shell program is used to realize the connection management module and the address mapping module, and glue the signaling module and the traditional file transfer module together, and realize the inter-module communication through the system call of the operating system. Loosely coupled integration. Specifically include:

[0022] 1) The user starts the shell program and provides the address of the file server to it;

[0023] 2) The shell program translates the local IP address and the server IP address into corresponding TNAs, corresponding to the source TNA and the destination TNA respectively;

[0024] 3) The shell program starts the signaling module through a system call, and provides source and destination TNA for it;

[0025] 4) The signaling module starts the optical path establishment process;

[0026] 5) If the optical path is established successfully, start the traditional file transfer client through the system call; if the optical path...

Abstract

This invention relates to a method for file tramsmission customer end based on dynamic optical paths of communication technology including: a user starts up a file transmission customer end to provide file service address to it, an address mapping module finishes the mapping of the IP address and TNA, a connection management module sets up lists for the required optical path, a notifying signaling module starts up the process of setting up the optical path and starts up a timer for the optical path, the signaling module sends out a request for setting up the optical path and receives the response, a file transmission module is completely the same with the traditional transmission customer, the signaling module dismantles the optical path after the file is transmitted.

Description

technical field [0001] The invention relates to a file transmission method in the technical field of communication, in particular to a method for a file transmission client based on a dynamic optical path. Background technique [0002] The development of optical network technology has greatly improved the bandwidth of network links. More and more applications with high bandwidth requirements are tending to use optical networks as their transmission networks. On the other hand, the introduction of the control plane into the optical network makes it evolve from a traditional network that can only provide static services to an automatic switching optical network with dynamic provision capabilities. The client equipment of the optical network can dynamically request the connection service of the optical network through a certain control interface. A connection in an optical network, also called an optical path, is an end-to-end link connecting two client-side interfaces of the...
