Abstract

The invention provides a device for transmitting data packets on a synchronous optical network. The device comprises an IP packet generating module for generating IP packets, a point-to-point protocol (PPP) packet generating module for adding protocol domain bytes to the IP packets and performing byte escape filling and byte addition to the IP packets according to the protocol requirements to obtain PPP frame format data, an SDH generating module for adding format expense to the PPP frame format data in accordance with an SDH protocol to obtain the data packets (namely, POS data packets)on the synchronous optical network, a serial parallel converting module for converting parallel 16-bit POS data packets into a serial 1-bit datum, an optical module for transmitting the serial POS data packets. The device for transmitting data packets realizes the generation and transmission of the POS data packet through an FPGA with low cost, avoids the use of an expensive and bulk special packet transmitter and reduces cost and energy consumption.

Description

technical field [0001] The present invention relates to the communication field, in particular to a device for sending data packets (Packet over Synchronous Digital SDH, referred to as POS data packets) on an optical fiber synchronous network. Background technique [0002] In common network applications, it is often necessary to measure factors such as network transmission conditions and data packet reception conditions. In order to perform measurement, testers usually use the method of sending test packets to achieve the purpose of measurement according to the transmission status of the test packets. [0003] During the measurement process, a dedicated packet sender is usually required to send data packets for measurement. At present, many contract sending machines have been put into use. These contract sending machines can send the data packets used for measurement according to the specific requirements of the network protocol, so as to realize network measurement. [00...
