Use, configuration and points for attention of network layer protocol (taking QoS as an example) when using OPNET for network simulation
2022-07-07 05:26:00 【Fish moon and a half】
utilize opnet Network layer protocol during network simulation (QoS For example ) Use 、 Configuration and precautions
This article only focuses on Qos Design and configuration of relevant strategies , Configuration of network multicast and unicast , It has been discussed before , Please look through 《 utilize OPNET Network unicast ( One server with multiple clients ) Design of simulation 、 Configuration and precautions 》 as well as 《 utilize OPNET Conduct network multicast (ASM) Design of simulation 、 Configuration and precautions 》 Two articles .
One 、 Set an application scenario
- To configure RED Strategy .
- Configure traffic shaping , The speed limit 2Mbps.
- To configure CAR Traffic monitoring .
- Configure layer 2 PQ agreement , Three layers WFQ agreement , Traffic is differentiated based on business , namely DSCP.
Two 、 Specific configuration
- add to Qos Configurator , namely Qos Attribute Config, At this point, the topology is as follows :
2. modify FIFO Strategies for RED. open QOS Configurator properties ,FIFO Profiles->FIFO Profile->Details->RED Parameters, choice RED.
3. Modification requires configuration QOS Strategic network devices , I choose to configure it on the port of the router connecting to the server . In this case , The router port connected to the server is IF2, I will Qos Configuration of , Configure on port .IP->IP Qos Parameters->Interface Information, Make the following configuration :
3、 ... and 、 Be careful
- opnet Properties of all network protocols in , The same as the use of hardware , It is instantiation into a configurator , This configurator is equivalent to a large container , The network protocol you want to configure accordingly , You have to configure it first , Then select directly when calling .
- opnet Provides configurators for many network protocols , such as QoS Configurator for , You can choose applications flexibly .
- Again opnet Use logic of network protocol in , It is basically consistent with the logic in the actual configuration . Before configuration , The logic of the protocol to be configured should be sorted out , Find out the needs .
- Use of protocol , such as QoS agreement , It can be configured as global or interface , See personal demand configuration .
