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. There is another way.

CCNA: TCP Sequence & Port Number This article can be read as the second part of the previous article CCNA: 3-Way Handshake where we discussed what makes TCP a reliable protocol for transmitting information. Lets discuss the TCP SEQ and Port numbers in this article. Port Numbers range from 1 to 65535.

CCNA: TCP 3-Way Handshake In this article, lets take a look at TCP three-way handshake and other useful information that makes TCP a reliable communication protocol. Before TCP can send any traffic, it first contacts the other device and establish a reliable and controlled connection. Now actual data transfer happens.

To do that it builds the Ethernet Frame and puts its MAC address as the Source MAC address (SMAC) and layer 2 broadcast address (ff:ff:ff:ff:ff:ff). A switch forwards the broadcast out all the ports in same VLAN (except the port where broadcast was received). PC-2 now creates an Ethernet frame to respond to the ARP.

This table is populated automatically when a switch receives a frame on a port. As a frame is received on a port, its source MAC address is noted. The switch receives the frame from PC-1 that contains the MAC address 80::01 on port 1. Port 1 is configured as a member of VLAN-11. Then PC-1 wants to communicate with PC-2.

In networking terms, a “flow” is a unidirectional set of packets sharing common attributes such as source and destination IP, source and destination ports, IP protocol, and type of service. Ethernet interface counters: records traffic statistics on an Ethernet interface. IP/ICMP/UDP/TCP. Ethernet/802.3.

The screen masking has a control box that accepts RS232 commands via ethernet. The Global Cache IP2SL device sends commands via a serial port. I have a DB9 to RJ45 adapter attached to the IP2SL device, and ethernet running from the adapter to the control box of the screen masking.
