Tasks Addressing

[Walid Aljoby]

Hi everyone,
Anybody please can help/guide about tasks addressing the in Storm? For 
example:When a tuple is received by specific worker process, it extracts the 
destination task id to determine to which destination executor thread should 
forward the tuple?So I can not realize where the worker process can find the 
task id, associated with received tuple? Is it embedded inside network packets? 
If there is any link that gives more information, please inform me.
Thank you and Regards,--WA
