Case Studies
Network monitoring
The customer need:
LTE networks need a high capacity, low convergence, redundant backhaul ethernet or MPLS network.
Mobile providers need also to monitor the quality and the load of the services they offer that will alert and react quickly to any problem.
The challenge:
Failures must be noticed at service level not at link level.
Depending on the capacity of each node there are several types of equipment, with different prices, different hardware abilities and even different operating systems.
The solution:
A set of standard protocols based on IEEE 802.1ag was implemented across the entire device range, from the low-end VxWorks based devices to the high-end WindRiver Linux devices.
Where available, network processor or FPGA support was used to decrease failure reaction times and increase s...
SDN load balancer
The customer need:
In the last decade broadband Internet and FFTH have become a comodity and with it came the need for cheap, bare-metal switches that can handle lots of traffic. In this context the incoming traffic needs also to prioritize certain types of traffic by using a different gateway.
The challenge:
Being bare-metal switches there is little software running on them and any application added there must be very light in order not to take resources from more important processes.
The deployment contains lots of devices that need to be controller from a central location and also each device must be aware of the other devices it is connected to.
The solution:
OpenDaylight is a successful modular SDN controller that can be used to define flows for the different types of traffic and apply them on all devices through a custom OpenFlow module i...
