Help needed to work around a TCP NAT port binding timeout issue on the WAN network that our system uses. This is somewhat of a special case because the WAN is through satcoms. Specifically, clients on the GGSN tun0 connection may keep TCP sessions open but silent for >5 minutes, and the satcoms closes unused TCP ports after silence for 5 minutes. All we need is the GGSN to periodically generate a few additional TCP ACK messages for ports that have been silent for 2 minutes. We don't want to use the similar Linux global settings for tcp_keepalive_time because that impacts other TCP sockets. I have a lab system available with source code on a public IP address you can access. I expect this will take about 10-15 lines of code and around 2-3 hours. More precise det...

I am looking for a knowledgeable and experienced developer to create a Diameter Java Module for me. This module must cover handle the main messages on Gy interface which is the logical interface between the gateway GPRS support node/traffic plane function (GGSN/TPF) and the online charging system/credit control function (OCS/CCF). The Gy interface, used for online charging control, adopts the Diameter protocol The developer must use Restcomm (aka mobicents and telestax) products: - Diameter Stack and Services (jdiameter); As job output result we do need following: - Installation logs/screenshots (we want to replicate installation in-house); - start/stop/restart instructions for the software - Description where to configure them (start configuration CLI, edit config files, contr...

...volume and radio signalling (two KPIs chosen because they give info about the message signalling load through the network depending on the IP used) using a testbed network. To measure and analyse these two KPIs, two computers that support both protocols with the necessary tools for analysis will be used. The first system having the wire shark application installed and connected directly between the GGSN and the internet to measure the IP data generated by the website or app. And the second system contains a wireless technology under the network vendor being used, and is directly connected to the RNC in the UTMS to measure all messages traveling across the radio part. The configuration used during the experiment corresponds to the UMTS network and the output towards internet is...
