Topology "Ring" or "TokenRing". How to setup?

Question

Computer networks

Good afternoon.
There are three PCs: A, B and C. Each has three network cards: one gigabit, for communicating with the "outside world", and two 10 gigabit, for exchanging data with each other. It is necessary to configure the network so that:
1. Do not use a switch;
2. So that when any of them is turned off, the "internal" network continues to work.
It seems to fit the "Ring" or "TokenRing" topology, but could not find instructions on how to set them up.

Answer 1

Apparently, the "Ring" topology is suitable

In this case, you will have to configure bridging between 10-gigabit interfaces on each machine, and somehow break the ring (RSTP, for example).

or "Token Ring",

Token ring is a separate LAN technology, with the Ethernet interfaces you have, you will not build a Token ring. In addition, I don’t remember that the Token ring performance was higher than several hundred megabits / s.
I support the proposal with IP routing between machines, in this case you will have to register two routes on each PC (direct and through another PC) to each of the remaining ones. Also, be aware that the resulting performance may vary depending on the network interfaces used and the performance of each machine.
UPD: can you clarify a couple of points? What is the planned load on 10 Gb interfaces (number of packets per second and average packet size, if possible, or just describe the traffic). Can the internal network be completely isolated from the external network, or is some kind of access needed from the outside? Do you plan to handle the situation when the PC is running, but the interface on it is inactive for some reason (cable break, etc.)? What OS is used on the PC, can it be changed to another?

Answer 2

and you won't find it.
Ethernet technology can neither ring nor tokenring ...
The ban on the use of a switch is incomprehensible.
Well, okay, let's assume that this is a purely educational task. Set up full connectivity. Those. computer A is connected by one network to computer B, the second to computer C, computers B and C are interconnected. On each computer you will have one network to communicate with the outside world. Assign a network with a /30 mask to the links.

Answer 3

With a "ring" topology, if any host falls, the entire network goes down. Plus, as far as I know, the speed with such a topology leaves much to be desired. And what makes you look in the direction of the "ring" and not the "star" in 2015? Certainly not the price of a budget hub.

Answer 4

Budget 10 gigabit hub? We can't find...
