Passari cellular routing and performance

As said before Passari Routers rely on many, many years of experience in cellular router connectivity. The very same frustrations our customers experience we share as well. There must be a better way. Better results must be possible. It requires hard work, dedication, brilliance and persistence. And .. the will to not being stopped by limitations.

Passari Routers are setting new standards in terms of ease of operations, functionality and performance. This in it self is already difficult enough per seperate item, we focused on all three of them together because these are related to each other.

Passari Routers offer exceptional functionalities:

  • Load Balancing
  • Seamless Load Balancing
  • Bonding
  • Diversity (Lowest Latency First)
  • Mesh @ LAN side

Load Balancing is described as ‘balancing load’ over multiple (cellular) connections. Steering services/applications over multiple WAN links make the overall connectivity more reliable and doubles, triples, quadruples etc. the WAN bandwidth. However a few realize that with Load Balancing actually the vulnerability to ‘not optimal performance’ is also doubled, tripled etc. due to broken services.

That is where Seamless Load Balancing comes in. If WAN links are broken the services passing through that WAN link are automatically transferred to still operational WAN links, in milliseconds. No services are broken, even streaming services, and all applications keep being functional.

Actually the same applies to Bonding. So why do bonding where seamless load balancing would suffice? Bonding works differently. A tunnel is created between an edge router, at the customers location, and a concentrating router somewhere in a datacenter. This tunnel utilizes all connections and all services are pushed through this tunnel. When a WAN link breaks the only effect is a decrease of overall bandwidth but services are uninterupted.

The main reason for Bonding is increasing reliability of the overall connection. Performance is a secondary priority. This was the main frustration for many bonding users because the low efficiency of bonding connection, due to too much bandwidth is required to maintain the overall tunnel, is actually costing too much. Too much loss of bandwidth equals too much loss of service performance.

But not Passari!

This is where Passari has raised the bar. Bonding efficiency over cellular connections will never be higher than 70-75%. This is due to the fact that bonding efficiency is mainly influenced by the latency variations between each individuel cellular link. These can greatly vary. Close to cell towers, good signal conditions, result in low latency cellular links. Another cellular link which at the same time is connected to a remote cell tower, due to another cellular subscription, automatically experiences a much higher latency. The different latencies between these links is killing the bonding efficiency. Bonding has to wait at the packets coming from the higher latency link before it can forward all the packets, also these from the low latency links. If the latency ratio between these links is growing higher this will result in a lower bonding efficiency overall. If this reaches towards 60-65% when having 2 or 3 cellular connections you can ask yourself what is bonding actually adding to the overall network concept. And that is what customers are doing more and more, especially where the individual bandwidths of 4G / 5G connections is increasing more and more.

Passari offers Bonding efficiency at 95-99%! We have rethinked the whole concept and flew in from a different angle. This also improved the ratio of latency variations where bonding still is an option. Where traditionally this ratio figure is at maximum about 500, otherwise the bonding efficiency would really become worth nothing, at Passari this ratio has been increased to 50.000 and still offering a very high bonding efficiency of about 95%. You just get more bang for your bucks!
