Description
Technical Field
The invention relates to a network communication technology, in particular to a method for self-sending a packet by equipment based on an optical transport network.
Background
An optical Transport network (otn) (optical Transport network) is based on wavelength division technology, and combines and strengthens some advantages of SDH, and is a Transport network technology in an optical layer organization network. The OTN can realize the transmission, multiplexing, routing selection and monitoring of service signals in an optical domain, and ensure the performance requirement and survivability of the OTN. The OTN may support various upper layer services or protocols, such as SONET/SDH, ATM, Ethernet, IP, PDH, fibre channel, GFP, MPLS, OTN virtual concatenation, ODU multiplexing, etc. Therefore, the OTN rate has a plurality of rates such as 1G, 2.5G, 10G, 40G, 100G and the like.
The device-to-device autonomous packet function used herein is the RFC2544 protocol. The RFC2544 protocol is an international standard proposed by the RFC organization for evaluating network-connected devices (firewalls, IDS, Switch, etc.). The test under the RFC2544 standard mainly comprises the following steps: throughput, delay, packet loss, back-to-back. The method is characterized in that no external test equipment is needed during testing, and the generation and the check of the test frame are finished through own hardware and software.
In the networking of the OTN, it is generally required to know whether the service configured on the device is normal or not and the service rate by sending a stream through a tester. However, the cost of the tester is relatively high, and in some places with a crude test environment or environments without the tester, it is impracticable to know whether the OTN service is normal or not and how large the service rate is.

step three, the control plane sets the content of RFC2544, including the sent message, the sending time, the rate size and the byte size;
