Add per-edge-events feature to SSSim.

This feature make the simulator acts on per-edge basis rather than on per-node basis.
It only works with the event-driven mode.

Refactor Makefile

4123e0f7 04/05/2017 03:20 PM Luca Baldesi

add per-link events.

Add a new flag (-E) to turn on the per-link event. This implies the event-driven mode (-e).
Each peer i sends an offer to its neighbor j every offer_interval times probability of j seconds, deterministically.

fix test case missing global variable and window analysis size in non-converging mode

80f4c362 01/19/2016 10:45 AM Luca Baldesi

add delay logging functionality

f850347b 01/13/2016 11:24 AM Luca Baldesi

add windowed analysis mode
add tests for convergence analysis function

make possible to analyze chunk data on blocks, evaluating the last available.

32c9a7bc 01/12/2016 10:51 AM Luca Baldesi

add auto convergence feature

this feature allow the specification a parameter of convergence on the average receiving delay and the termination of the simulation

78d8960f 09/17/2015 03:26 PM Luca Baldesi

add network load factor option.

This feature enables to specify the maximum stress on the network during streaming.
Default is netload=1, so the sum of chunks sent in one chunk time is at maximum equal to the number of peers.

8d46f8f6 09/16/2015 04:10 PM Luca Baldesi

merge graph_matrix branch and fix conflicts.

e0ad77f8 09/16/2015 03:09 PM Luca Baldesi

Add event driven module

Enables a more fine control on the simulation

prevent trace option to log scheduling related to overlay monitoring

d6fa79fc 09/16/2015 09:36 AM Luca Baldesi

fix bug in matrix_shrink function.
bug affects the shrinking of vectors (one-dimensional matrix)

4136f032 09/15/2015 03:21 PM Luca Baldesi

add important annotation.
reminds that the buffer length defines the playout delay and hence if a chunk can be offered.

d9aa6226 09/15/2015 02:07 PM Luca Baldesi

solve bug related to peer pointers

db6a9d7d 09/15/2015 12:18 PM Luca Baldesi

It makes possible to delete one row and one column from a matrix.

add copyright banner to overlay files

91dc88f2 08/03/2015 05:40 PM luca

combine graph files, matrix eigenvectors and simulation

This commit bind together SSSim with the matrix module which can load from file ".edges".
the centrality properties of the peers can be derived from the matrix to speed up the distribution

ec88b090 08/03/2015 02:37 PM luca

add tokens check function for looking for known tokens

this can be useful when checking if a flag has been specified through command line

refactor action event initialization and standardize event priority

two default priority levels are defined: HIGH_EVENT_PRIORITY and LOW_EVENT_PRIORITY

if events have same time the new one is pushed in the last position possible (FIFO)
the priority flag can be used to override this behaviour
