GPRS/EDGE configuration

By ft85 ·
Am Working in a Telecom Company ,we are ISP offering GPRS/EDGE , and soon we want to launch 3G , but now the problem is when we were on GPRS/EDGE , we had some challenges in terms of connectivity , investigations have been revealed that there is an unacceptably high packet losses between ZTE Router and our Company router, at about 50% higher resulting in a serious degraded Quality of service for GPRS . And my task is to make this problem resolved. Our current Architecture design is like this : Our GGSN is connected Via 2 firewalls/routers (which means one firewall is Provided by ZTE (the company which provided equipment for our Telecom Companies and another Provided by Our telecom Company for security Policies, my understanding is to have data throughput depends on
-data throughput of the SGSN/GGSN nodes.
-Bandwidth allocated for packet data
-Data throughput at the radio access network
-Uplink/Downlink radio network quality.

So all I need is to have the packet data core network reconfigured and optimized ahead of the 3G implementation. I will appreciate if anybody there suggests or help me how to go about this

Thanks In advance for your help .

Best regards

"investigations have been revealed that there is an unacceptably high packet losses between ZTE Router and our Company router, at about 50% "

Is the above the main issue you need to solve?

What specific devices are these two routers?

What is the interface between them? (E.G. edge, Gigabit Ethernet, etc)

What sort of total bandwidth is going over the link?

How do you know you have 50% packet loss...what testing was done?

Do you have admin access to both routers (e.g. the ability to look at interface statistics and so forth?)?

yes sir the above issue is what i want to solve


the routers

One is a CISCO 7200 Series and another one for ZTE is a JUNIPER 4350 , and behind the ZTE router there is a firewall, from the firewall then 2 switches connected to SGSN and GGSN

the Interface between them is IP

the total bandwidth is about 4Mb(2.5 Down/1.5 ups)

we tested by pinging the in between .

yes i do have access in one and am sure they also have access to theres
