RTI DDS Qos profile history not working as expected
java,publish-subscribe,qos,dds
Why you see what you see: You are using Subscriber.DATAREADER_QOS_DEFAULT and Publisher.DATAREADER_QOS_DEFAULT, and the 'is_default_qos' boolean is set on the Keep_Last depth 1 profile. What it is doing under the hood: When you have is_default_qos flag set on profile "Foo", THAT is the profile that will be used, when you...
TOS to 802.11 QOS Control on iPhone
You are looking at two different values - one is the layer 1 value and the other is a layer 2 value. There is no direct correspondence between the two - some mapping needs to be provided. In your case this mapping must be performed by the Access Point (or...
DDS 9th topic causes a crash
I found on this is because of the max objects per thread by default is set to 8 by the qos. To change this setting, before your first topic is created you must do the following. DomainParticipantFactoryQos factoryQos = new DomainParticipantFactoryQos(); DomainParticipantFactory.TheParticipantFactory.get_qos(factoryQos); factoryQos.resource_limits.max_objects_per_thread = 2048; DomainParticipantFactory.TheParticipantFactory.set_qos(factoryQos); This then sets the...
DSCP Precedence
java,network-programming,ip,qos
Assuming I understood you correctly, just perform a 3 bit logical shift to the right: dscp >>> 3 Like this: for (int dscp = 0; dscp < 57; dscp++) { System.out.println("DSCP:" + dscp + " Precedence:" + (dscp >>> 3)); } Output: DSCP:0 Precedence:0 DSCP:1 Precedence:0 DSCP:2 Precedence:0 DSCP:3 Precedence:0...
I can't find DSCP field in IP header, only the deprecated TOS field
The DSCP field has taken the place of the ToS field: these are just two names for the very same field in the IP header. If the sender put a DSCP value into the field, then it's just fine to access it using the ToS field. Note however that whether...
How do I listen for network traffic on an interface/device using Java?
java,networking,network-programming,qos
What you're looking for is simply outside of the scope for a universal java application. If you're planning on keeping a specific OS in mind, such as Windows or Linux (my following examples), then there are a few things you can do. For Windows, any given application will be unable...
How to measure QoS parameters in the ns-3 simulation
simulation,voip,ns-3,qos,wimax
From my short experience, Generally you need to use the flowMonitor helper class to get the statistics. Refer below. http://www.nsnam.org/doxygen/classns3_1_1_flow_monitor_helper.html If it is just the basic statistics like bytes received, sent etc, you have already functions in the packet class that can be used to get the values. Else you...
Is it possible or even allowed to implement QoS on server and client? Live555
client,reporting,rtsp,live555,qos
For the client side, a example could be found from openRTSP test programs. openRTSP could display QOS client information : Outputting QOS statistics Use the "-Q" option to output QOS ("quality of service") statistics about the data stream (when the program exits). These statistics include the (minimum, average, maximum) bitrate,...
Windows 7: Launching an application silently with admin privileges under default user account?
This goes against the security of the OS. You are basically asking to be able to bypass a security measure enforced by the OS. If you were allowed to do this, any malicious code could do the same thing, so I don't think that you can (or should) do it.
