Programming a routers traffic

Posted on 2005-04-12
Last Modified: 2010-04-26

We have a Baystack Advanced Remote Node Router (model: CV1001004) that utilizes a 64kb line to link traffic with another branch of our company in another province (state); basically a WAN.

We run the HEAT application ( a program that allows us to log calls and send out technicians to job sites ) at our branch whereby packets of data are sent over the WAN via the router to our HEAT program. Jobs are logged at our main branch and then sent down to us, we respond to the jobs and can allocate the required technicians and equipment accordingly.

Our user of the HEAT program is constantly experiencing ODBC errors in the program which have been narrowed down to being caused by other traffic present on the line (our Main Branch runs queries, store procedures and reports off our database throughout the day). Installing a bigger line, upping it to 128kb, has been said will solve this problem and the ODBC errors will cease but this is a costly solution and I would like to know if there is a way we can program this specific router and give HEAT traffic priority on the line which will hopefully in turn stop ODBC errors occurring on the HEAT program.

Thanks in advance

    Well the only drawback abt routers is that they handle a minimum of 64 Kbps traffic so u cannot break down the traffic further. At least not if u talk in terms of just the router. The router cannot enable TOS or QoS as u intend to at least not the model u have IMO. However what you can do is to have a software solution in place where u can have a bandwidth limiting software running on a server which can leave a dedicated amnt of bandwidth to the HEAT application server. However this will also work if the HEAT application is running only on one computer and not multiple systems. Also what abt the Internet connection on the other end?

    They also need to have enuf bandwidth to acknowledge and send back data to u. This wont work if either of the 2 sides is having a traffic jam.

    Any other software solution which involves TOS like the one u require will be more expensive than upgrading to a 128 KBPS line.

    OMG, someone is still running ARN's!?!?  To my knowledge, those are End of Life and End of Support from Nortel.  I would urge you to stronly consider using this issue to upgrade to some Cisco routers which are much more supportable, configurable, friendly, etc. etc.

    Although I'm not sure exactly how to do it, I'm pretty sure it is possibe to rate limit traffic based on type.  So, you could choke your other traffic down, thereby allowing your HEAT traffic to proceed unimpeeded.

    Another solution is to look at a MUCH faster Internet connection - via DSL or Cable - and use VPN.  Over time, this would probably save you money vs. a leased line scenario.

    Hi pseudocyber

    So your suggestiong would be to not upgrade the line initially , but rather invest in first upgrading the router to one that is more managable and programmable. Do you have a few examples of these types of routers available.

    Even Nortel has dumped the line of Baystack routers and doesn't even make routers ... they recommend Juniper which is fine if you have the money.  

    You could save some and get yourself a basic Cisco.
