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

CloudFaire

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. It's a major extension to the TCP protocol, and historically most of the TCP changes failed to gain traction.

CCNA: TCP/IP Stack

The Network DNA

CCNA: TCP/IP Stack TCP/IP Stack is the most widely used protocol stack. TCP/IP stack is a conceptual model consisting of network communication protocols. It specifies how data should be packetized, addressed, transmitted, and routed across the network. TCP/IP networks use TCP or UDP protocol at this layer.

IoT has an identity problem. Here’s how to solve it

CATO Networks

Figure 1: Different network protocols for OS identification based on the OSI model Starting from the bottom of the stack, at the data link layer, exists the medium access control (MAC) protocol. Over this protocol, a unique physical identifier, called the MAC address, is allocated to the network interface card (NIC) of each network device.

NetFlow vs. sFlow

Kentik

It is used to record statistical, infrastructure, routing, and other metadata about traffic traversing an sFlow-enabled network device. sFlow can also export metrics derived from time-based sampling of network interfaces or other system statistics. Ethernet interface counters: records traffic statistics on an Ethernet interface.
