What are the traffic compression mechanisms?

Question

Mikrotik

First of all, solutions from tsiska or mikrotik are of interest. I explain the situation. The main gateway has a 100 megabit channel to the Internet. And one of the offices has only a 10 megabit channel to the gateway. How can you compress traffic with regular means? I'll be grateful for the tips.

Answer 1

No, just like that, the operation of compressors requires large computing resources, for routers this is an unacceptable luxury, they try to use a minimum of software and a maximum of hardware logic. Of course, you can use traffic prioritization (QoS), but it will also be useless in your case, just expand the channel.

Answer 2

The main gateway has a 100 megabit channel to the Internet. And one of the offices has only a 10 megabit channel to the gateway.

Please specify what exactly is the problem. What is 10 Mbit/s of bandwidth used for? What are they missing?

How can you compress traffic with regular means?

It is not yet clear how exactly traffic compression will help you. The easiest, most supported, predictable way to increase the performance of Internet access from your specified office is to increase the bandwidth to the gateway.
Other options are also possible. If the web functionality of the Internet is mainly used, you can set up a caching proxy server in the problematic office and, in the case of using cisco equipment, enable it using wccp. Here is an example.
Another option is to use the "Internet accelerator" ( WAN acceleration). In the case of cisco, the WAAS family. Has implementation of traffic compression, data deduplication and TCP performance optimization. I had no experience in the industrial operation of this product, but I can assume that for the competent implementation of such a solution, you need to understand exactly how applications work on your network, know the nuances of implementing the TCP stack on servers / workstations and be prepared for hard-to-explain bugs. And all this for the sake of an unguaranteed performance improvement in your case.
Finally, there used to be hardware traffic compression modules for 2600, 7200, but, if I'm not mistaken, they have reached the End-of-life status.
In short, it is not entirely clear how (how much) traffic compression will help you. I am not aware of the presence of a built-in (which does not require an additional license, an additional module) similar functionality in cisco equipment. I have outlined the options for you.
UPD : Found such a supposedly free solution. I think it's worth paying attention to it. Although, I repeat, WAN optimization is not a trivial matter.

Answer 3

There was an article about this on Habré:
habrahabr.ru/company/croc/blog/214693
And so, if there is no way to expand the channel, then maybe buy a second one, perhaps from another provider?
