Multi-Path TCP: revolutionizing connectivity, one path at a time

CloudFaire

As a result, Internet devices usually use a single path and let the routers handle the path selection. Enter Multi-Path TCP (MPTCP), which exploits the presence of multiple interfaces on a device, such as a mobile phone that has both Wi-Fi and cellular antennas, to achieve multi-path connectivity. There is another way.

Latency is not a new problem in networking. Not as difficult as time travel, but it’s difficult enough so that for 30+ years IT professionals have tried to skirt the issue by adding more bandwidth between locations or by rolling out faster routers and switches. Fast forward to today, most networks enjoy five nines (99.999%) of uptime.

A TCP/IP reset (RST) flag is sent when my router loses SIM connection and then recovers [closed]

Network Engineering

I have a router that uses a SIM card for connectivity, and I create a socket connection. After the connection is disrupted, when I attempt to send a packet from the server using the previously established socket, the router responds with a RST (reset) packet. I have checked the firewall of the router but it seems to be deactivated.

CCNA: IP Routing

The Network DNA

CCNA: IP Routing (Communication between two different networks) In this article, we are going to talk about IP routing which is a process of communication between two different networks. Here well see how a layer 3 switch or a router transmit packets between different networks using the layer 3 destination address.
