Difference between UDP and TCP using dual stack socket. RRS feed

  • Question

  • Hi, guys.
    Using dual stack socket, my callout driver received the following events.

    [TCP]
    Layer ID : FWPS_LAYER_ALE_RESOURCE_ASSIGNMENT_V4  /  transportEndpointHandle : 0x108c  /  flowHandle : 0x0 
    Layer ID : FWPS_LAYER_ALE_RESOURCE_ASSIGNMENT_V6  /  transportEndpointHandle : 0x108c  /  flowHandle : 0x0 
    Layer ID : FWPS_LAYER_ALE_AUTH_RECV_ACCEPT_V4  /  transportEndpointHandle : 0x108f  /  flowHandle : 0x1146 
    Layer ID : FWPS_LAYER_ALE_FLOW_ESTABLISHED_V4  /  transportEndpointHandle : 0x108f  /  flowHandle : 0x1146 
    Layer ID : FWPS_LAYER_STREAM_V4  /  transportEndpointHandle : 0x0  /  flowHandle : 0x1146 
    Layer ID : FWPS_LAYER_STREAM_V4  /  transportEndpointHandle : 0x0  /  flowHandle : 0x1146 
    Layer ID : FWPS_LAYER_ALE_ENDPOINT_CLOSURE_V4  /  transportEndpointHandle : 0x108f  /  flowHandle : 0x1146 
    Layer ID : FWPS_LAYER_ALE_RESOURCE_RELEASE_V4  /  transportEndpointHandle : 0x108c  /  flowHandle : 0x0 
    Layer ID : FWPS_LAYER_ALE_RESOURCE_RELEASE_V6  /  transportEndpointHandle : 0x108c  /  flowHandle : 0x0 

    [UDP]
    Layer ID : FWPS_LAYER_ALE_RESOURCE_ASSIGNMENT_V4  /  transportEndpointHandle : 0x10c4  /  flowHandle : 0x0 
    Layer ID : FWPS_LAYER_ALE_RESOURCE_ASSIGNMENT_V6  /  transportEndpointHandle : 0x10c4  /  flowHandle : 0x0 
    Layer ID : FWPS_LAYER_ALE_AUTH_RECV_ACCEPT_V4  /  transportEndpointHandle : 0x10c4  /  flowHandle : 0x1191 
    Layer ID : FWPS_LAYER_ALE_FLOW_ESTABLISHED_V4  /  transportEndpointHandle : 0x10c4  /  flowHandle : 0x1191 
    Layer ID : FWPS_LAYER_DATAGRAM_DATA_V4  /  transportEndpointHandle : 0x10c4  /  flowHandle : 0x1191 
    Layer ID : FWPS_LAYER_DATAGRAM_DATA_V4  /  transportEndpointHandle : 0x10c4  /  flowHandle : 0x1191 
    Layer ID : FWPS_LAYER_ALE_ENDPOINT_CLOSURE_V6  /  transportEndpointHandle : 0x10c4  /  flowHandle : 0x0 
    Layer ID : FWPS_LAYER_ALE_RESOURCE_RELEASE_V4  /  transportEndpointHandle : 0x10c4  /  flowHandle : 0x0 
    Layer ID : FWPS_LAYER_ALE_RESOURCE_RELEASE_V6  /  transportEndpointHandle : 0x10c4  /  flowHandle : 0x0 

    Why so different?

    Thank you.
