    193193  Substitute ''$HOME/ccnx-atmos'' for your actual Atmos build directory, and $''DATAFILE'' for the appropriate filename as described above. [[BR]]
    194194  On the client host you chose, run ''./client.py'' from the data directory and select a few dates from January and February of 1902 for date ranges. Make note of what interests are received at the server, and how long the transfers take. [[BR]]
     195  '''Note:''' You probably need to change the permission of client.py and script.py on the researcher/collaborator nodes to be executable. For unknown reason, sometimes GENI nodes will not configure the ccnd routing table for you. The result is, you are not able to get data from datasources. In this case, run ''ccndstatus'' on ''router'' and any researcher or collaborator node that you are using to confirm the routing table entries are missing, then run the following on node ''router'':
     196{{{
     197ccninitkeystore
     198ccndc add ccnx:/ndn tcp datasource1
     199ccndc add ccnx:/ndn tcp datasource2
     200}}}
     201  Then add the corresponding routing table entries on the researcher/collaborator node you are using. For example, in this case, I am using researcher1, then I should run the following on researcher1:
     202{{{
     203ccninitkeystore
     204ccndc add ccnx:/ndn tcp router
     205}}}
     206  In this example, I am using date range from 1902/01/01 to 1902/01/02. The output from datasource1 is as follows:

    195541  Change the client and server programs to use this URI, restricting CCNx transfers to a granularity of one month, but preserving the ability of users to retrieve at one day granularity: ''/ndn/colostate.edu/netsec/pr_<year>/<month>''[[BR]]
    196542  '''Implementation Hints:''' It is important understand how ''script.py'' uses NetCDF commands to extract relevant dimensions in the data files. The client (''client.py'') breaks up a user’s request into a collection of URIs (one for each day) and fetches them sequentially. For each URI, script.py generates a list of timestamps (a floating point number indicating the number of days elapsed since January 1, 1901). From the NetCDF data files, script.py extracts the fields that lie within these timestamps. The server side changes are minimal. Once a month’s granularity of data is received at the client side, it should be filtered to match the specific days requested by the user. [[BR]]
    197543  Retrieve a variety of dates in the January to February 1902 date range, and note again what interests are received at the server and how long the transfers take. [[BR]]
     544  '''Code Answer: ''' Source code can be found here: [http://www.gpolab.bbn.com/experiment-support/CCNExampleExperiment/forInstructors/ SourceCodeAnswers].[[BR]]
     545  '''Change Log: '''
     546    - client.py: modify the granularity of requested data from one day to one month; fetch the data via `client`, then look into the fetched file and extract data corresponding to the requested time rage -- most of the changes happen in this file
     547    - client.c: no change
     548    - server.c: a little change: since the trunk_interest_name does not include `day` information (the client only send out `/ndn/colostate.edu/netsec/pr_1902/01` instead of `/ndn/colostate.edu/netsec/pr_1902/01/08`), I added a default starting day 01 for every request/interest, change can be found from line 231 to line 233.
     549    - script.py: fetches data for a whole month instead of one day. [[BR]]

    199    What general difference do you see in network behavior between these solutions?
     551   What general difference do you see in network behavior between these solutions? [[BR]]
     552   '''Answer: ''' Apparently at granularity of month, the amount of data transferred is larger (about 20 Mega Bytes per month), compared with granularity of day (about 660 Kilo Bytes per day). [[BR]]
     553   Moreover, at month-granularity, the size of file transferred is big so as to give TCP enough time to accelerate its throughput while at day-granularity it is not the case. [[BR]]
    200554   - '''Question 2.1 B''' [[BR]]
    201555   Which URI scheme is more efficient in time and network resources if the user only wants a few days of data? What if the user wants a full calendar month of data? [[BR]]
     556   '''Answer''': If the user only wants a few days of data, day-granularity is better: it consumes less network resources (bandwidth) and takes less time to fetch. If the user wants a full calendar month of data, it is better to use month-granularity since in this case, one request from the client side is enough, compared with around 30 (number of days in a month) consecutive requests from client side (which takes longer to query) if using day-granularity.
