Ehernet traffic

Generating Ethernet traffic based on traffic profile

Stochastic Modeling

  • Distribution-based traffic
    Demonstrates the use of the Traffic block to generate transactions based on multiple districtions
  • Ethernet Traffic
    Generating Ethernet traffic based on traffic profile
  • Image Traffic
    Generate images in the form of a Matrix for processing
  • SysML
    Mapping SysML to a performance analysis model for Model-based System Simulation
  • Queue
    Use of the Queue block to model the buffer management, ingress/egress queues, FIFO and SRAM in FPGAs
  • Server
    Use of the Server block to model time-consumption by system resources. Resources can include hardware, RTOS, middleware, networks and interrupts
  • SystemResource
    Mapping an MPEG use case to SystemResources for performance and power analysis
  • Quantity-Shared
    Modeling consumption of quantity which can be memory addresses, semaphore pool and slots avaialable in a parking garage
  • Channel
    Use of the Channel block to model communication, wireless and interface channels
  • Using Spreadsheet

This is a Ethernet Traffic Generator block. This block can be used to generate traffic for network model including AVB, Ethernet and AFDX. This block requires an associated Traffic Table block and can generate multiple concurrent traffic streams for a fixed time duration. Each row (traffic stream) can be associated with a different Node. On the output port, a OUT block can be added with the Task_Source as the Destination field. Each Node can have a IN block with Task_Source name. The key fields utilized are the Task_Size, Task_Source, Task_Destination, Task_Hop, Task_Trace, Start_Time, Stop_Time, Mbps, Task_Rate, Identifier, Network_Message, Network_Message_Type, Protocol and Type.
