Mobile USB modem AT commands

These commands will help you to know about the negotiated QoS parameters i.e. the down link and up link speed. Use these commands if MDMA software doesn't work with your mobile.

1. Download  PuTTy software. Run it and select Serial, enter the COM port and press Open.

2. COM port no. may be obtained from Device Manager>Modems>Properties>Modem tab.

3. Now in the black screen that opens, just type the following AT commands and press Enter after each command.
ate --------------------------------------set echo of commands
at+cgdcont=1,”IP”,”uninor” ---------- replace uninor with your Access Point Name
at+cgact=1,1 -------------------------activate Profile saved previously, try again if CME Error: 130 occurs

at+cgpaddr=1 -------------------------check assigned ip address for profile 1, try again if Error
at+cgeqneg=1 -------------------------display negotiated QoS parameters, try again if CME Error: 130

The output format is like

+CGEQNEG:<active_cid>,<traffic_class>,<max_br_ul>,<max_br_dl>,<guar_br_ul>,<guar_br_dl>,...,

where

<traffic_class>: decimal (0-4); The type of application

0   conversational

1   streaming

2   interactive

3   background

<max_br_ul>: decimal (0-xxxx); maximum bit rate ul

<max_br_dl>: decimal (0-xxxx); maximum bit rate dl

<guar_br_ul>: decimal (0-xxxx); guaranteed bit rate ul

<guar_br_dl>: decimal (0-xxxx); guaranteed bit rate dl

Sample outputs:

+CGEQNEG: 1, 3, 209, 254, 209, 254, 2, 150, 4, 4, 2, 3, 3 --- 3G result reliance

+CGEQNEG: 1, 3, 115, 115, 255, 255, 2, 150, 4, 4, 2, 3, 3 --- 2G result reliance

+CGEQNEG: 1, 3, 88, 88, 255, 255, 2, 150, 4, 9, 1, 0, 1 --- uninor

+CGEQNEG: 1,3,256,256,0,0,0,1500,"E4","E5",2,4000,3,0,0 --- loop

Thus, in first case <max_br_ul>=209 kbps and <max_br_dl>=254 kbps and so on.

Additional commands:

at+cops? ---------------------------------view network operator info
Output format: +COPS: (<mode>,[<format>,<oper>[,<AcT>]]),…


<mode>
0.Automatic network selection (<oper> ignored)
1.Manual network selection, <oper> must be present, <AcT> is optional.
2.Deregister from network.
3.Set <format only, no registration/deregistration.
4.Manual selection with automatic fall back (enters automatic mode if manual selection fails).


<format>
0.Long alphanumeric string
1.Short alphanumeric string
2.Numeric ID


<oper>
String (based on <format>) that identifies the operator.


<AcT> Network access type
0.GSM
1.Compact GSM
2.UTRAN
3.GSM with EGPRS
4.UTRAN with HSDPA
5.UTRAN with HSUPA
6.UTRAN with HSDPA and HSUPA


Sample outputs:
at+cops?
+COPS: 0,2,405926,0 ------ 0=GSM


at+cops?
+COPS: 0,0,"Reliance",2 ---- 2=UTRAN or 3G

Optimize bandwidth during ISP speed cap at 512 kbps

Nowadays many ISPs impose speed cap of 512 kbps after FUP limit.
You need to utilize this reduced speed completely to watch streaming videos without buffering.

To utilize this reduced bandwidth fully, limit your internet speed to 560 kbps using a free software called netbalancer.
Download the free version of the software at http://seriousbit.com/netbalancer/

Now open main window and go to Edit > Settings > Limit all System Traffic and here just set the download limit to 560/570 kbps.

Now experience a better performance even at low speeds of 512 kbps.
Tested on BSNL broadband. Should work fine with any ISP.

Cheapest BSNL broadband plan in India - 2012

"BSNL combo ULD 900" is the best and cheapest broadband plan in India.

You get 8 GB download + 8 GB upload at a whooping bandwidth of 4 Mbps and after either download or upload crosses the 8 GB monthly limit, only the downloading is capped at 512 kbps while uploading is still uncapped at 800 kbps!!!


Moreover, the annual plan reduces the effective rate to 900-150=750 Rs. per month!!! Adding taxes it comes up to 840 Rs. PM.
Working/Retired  Government employees can further avail 20% discount on rental to reduce the cost to   600 Rs. per month + tax = 670 Rs. per month.

Additionally, you also get 400 units of calls free per month!!!
This means 400x3=1200 BSNL to BSNL/MTNL All-India STD/Local free minutes
OR 400 free minutes to other local/STD mobiles.


Thus, leaving about 200 Rs. as monthly call costs(without any telephone rent), 
effective cost per GB is (840-200)/8=640/8=Rs.80 PM and also you get unlimited broadband at just Rs.640 PM.
What can be more cheaper than this!!!
So you might as well consider this plan seriously if you are a heavy internet user.
Note:
On their website they say that the free usage of 8 GB comprises of both download and upload but believe me it is not true as I am using this plan for the past 8 months and I am getting free usage of max. 8+8 GB.

Note:

1. Sometimes, the hyperlinks may be dead. In that case you can search for an episode using the search box given below the episode list. Ex. "Two and a Half Men Episode 1 Pilot".

2. Use Google DNS 8.8.8.8 for accessing putlocker server as it is blocked by BSNL's DNS server.

3. Use any of the proxies from my previous post http://networkraid.blogspot.in/2012/05/bsnl-broadband-  speed-hack-may-2012.html if changing DNS server does not solve the problem.

4. Use AdBlock plugin to optimize viewing experience.

For Bollywood movies, Google video search with a duration filter of 20+ min along with keywords like dvdrip will be my best choice.
Happy TV viewing....:)

Tracing BGP AS path to your IP

We can trace an external ip address using trace route command. But that will only indicate the path taken from our PC to the other host which will ultimately affect your upload bandwidth.

To get a fair idea of our download bandwidth, the reverse path i.e. the path taken by packets to travel from the external host to our local host, must be considered. For this purpose we need a facility to perform reverse trace route.

This facility is provided by websites popularly known as network looking glass. The looking glass of an ISP  contains scripts which fire network commands from the ISP's routers. These commands may be executed by any external looking glass user.

Some useful looking glass URLs:

http://lg.level3.net
https://lg.airtel.in/              (Airtel)
http://lg.llnw.net/index.cgi
http://lg.softlayer.com/
http://lg.as6453.net/lg/      (TATA)
http://ubs.flagtel.com/lg     (Reliance)
http://www.as3257.net/lg/
http://lg.choopa.net/

BGP path trace and ip trace route are two of the popular facilities provided by a looking glass.

Explaining the BGP Path trace output from http://lg.level3.net,

We can select the router location of the specific ISP --- Seattle,WA.
Then we input our IP address with an optional prefix --- 117.207.216.204.

The output of this BGP table query tells that there are two possible paths from that router.
It further displays the sequence of ASNs(Autonomous System Numbers) which lie on the BGP AS-translation path.
Here, both the paths go via AS3561(Savvis) and then finally to the destination AS9829(BSNL).
The green lines signify the currently selected best active path selected on the basis of BGP algorithms.

IP trace route is same as the normal tracert command in Windows but it traces the reverse path.

Checking currently used AS paths from a given IP

Initially, input the given IP in the search box at http://bgp.he.net/.
You will get its corresponding announcement IP address with prefix.

Here the announcement is as 117.204.160.0/20.
As you can see, there can be more than one announcements per IP but the prefix length will be different.
Greater the prefix length, more will be the sub network selectivity.

Then go to http://bgplay.routeviews.org/ and click on "Start BGPlay" button.

Accept the java applet permissions.

Here, enter the earlier prefix found by you.
Select the from-to dates as necessary. You can get current status by entering the latest date range or you can get a more stable status by selecting a longer time span of say 3-4 months.

After executing, fast forward it till the end to get the completed picture.
A sample run is shown below,

The nodes in the graph are the ASNs.
Here we observe that maximum connections(lines) are delivered through AS6453(TATA) and AS18101(Reliance).

Checking your ISP peering status

You can check your ISP peering here http://bgp.he.net/

Then click on the ASXXXX link to get below page.

The names given in the first table are the ISP's upstream or supplier BGP peers. Here they are Savvis, TATA, etc.
Each peer is an independent network and so has a unique ASN(Autonomous System Number) assigned to it. For ex. BSNL's AS no. is 9829.

You can get any given IP's network info by entering it in the Search Box.
Alternatively, you may just enter the ASN to get the corresponding network's information.

Clicking inside the table's cell leads you to the corresponding network's info page.
