Problems solved by technology

However, the cost of the tester is relatively high. In some places where the test environment is simple or there is no tester, it is impossible to know whether the OTN service is normal and the service rate is high.

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] A function based on the device spontaneously sending packets under the optical transport network, including the following steps:

[0019] 1. Network construction, equipment access to OTN network as required;

[0020] 2. Set up OTN services on the control plane;

[0021] OTN equipment interface adaptation supports STM-16 / 64 / 256 SDH services, OTU1 / 2 / 3 OTU services, GE / 10GE Ethernet services, 1G / 2G / 4G / 8G / 10G FC and other customer service access, And STM-1 / 4, FE and other low-speed customer service access, the customer side service generates ODUk (k=0, 1, 2, 2e, 3, 4) channel signals after mapping and multiplexing.

[0022] 3. Set the content of RFC2544 on the control plane, including the sent message, sending time, rate size, byte size, etc.;

[0023] The sent message refers to the data packet transmitted on the physical port, the sending time, namely duration, ...

Abstract

The invention discloses an equipment packet self-sending method based on an optical transport network. The method comprises the following steps: networking construction: equipment is accessed to an OTN network according to requirements; the control plane is provided with an OTN service; the control surface is provided with the content of RFC2544; the forwarding plane is responsible for forwardingthe content of the message, so that the message constructed by the RFC2544 is transmitted in the OTN network; RFC2544 is enabled in the configured OTN service, simulating tester flow sending, and a corresponding data packet is forwarded according to the configuration issued by the control plane; and whether the OTN service is normal or not is known by checking the result of the RFC2544, and the rate of the service is known through the maximum throughput. According to the invention, whether the OTN service is normal or not can be known in a simple and crude test environment or an environment without a tester, the configured OTN rate is known, and the method is quick, accurate, economical and convenient.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method for spontaneously sending packets based on equipment under an optical transport network. Background technique [0002] Optical Transport Network (OTN) is abbreviated as OTN (Optical Transport Network), which is based on wavelength division technology, integrates and strengthens some advantages of SDH, and organizes the network at the optical layer. OTN can realize the transmission, multiplexing, routing selection and monitoring of service signals in the optical domain, and guarantee its performance requirements and survivability. OTN can support a variety of upper-layer services or protocols, such as SONET / SDH, ATM, Ethernet, IP, PDH, FibreChannel, GFP, MPLS, OTN virtual concatenation, ODU multiplexing, etc. Therefore, OTN rates include 1G, 2.5G, 10G, 40G, 100G and other rates. [0003] The self-sending packet function used in this article is the RFC2544 protocol. T...
