Calculating Expected Response time on Cloud Analyst

[Yodit Gebrealif]

Dear all.
I want to calculate the expected response time of each task and then try to develop new algorithm based on the result of expected response time. the formula to calculate this expected response time is

Response Time = Fint - Arrt + Tdelay

where,

Arrt is the arrival time of user request and

Fint is the finish time of user request and

Tdalay is the transmission delay.

However, Tdelay can be calculated as

Tdelay = Tlatency + Ttransfer

Here, Tlatency is the network latency and Ttransfer is the time taken to transfer the size of data of a single request (D) from source location to destination. Tlatency is taken from the latency matrix (after applying Poisson distribution on it for distributing it)held in the Internet characteristics

.

Ttransfer = D / Bwperuser

where Bwperuser = Bwtotal / N;

Bwtotal is the total available bandwidth (held in the Internet characteristics) and N is the number of user requests currently in transmission.

Now I want you to help me that how can i get the FINISH TIME of user request and Tlatency. please if you have can you give me some block of codes? thank you in advance

Hi

is Fint have the same meaning of cloudlet finish?

if yes, CloudSim have h method that gives u the current finesh time of each cloudlet.

dear Shaden.
Thank you for your response. Yes it is cloudlet finish time. but i didn't fined any method on cloud Analyst simulator which calculate this finish time. so please help
