Layer 3 provides switching and routing technologies, creating logical paths, known as virtual circuits, for transmitting data from node to node.
#WAVES L2 VS L3 MAC#
The MAC (Media Access Control) sub layer controls how a computer on the network gains access to the data and permission to transmit it and the LLC (Logical Link control) layer controls frame synchronization, flow control and error checking. Layer 2 is the data link where data packets are encoded and decoded into bits. This standard is a guide that allows engineers to keep communications organized. It’s a controlled hierarchy where information is passed from one layer to the next creating a blueprint for how information is passed from physical electrical impulses all the way to applications. The OSI, or Open System Interconnection, is a networking model comprised of seven ‘layers’. The reason we are having a discussion about layer 2 or layer 3, is that your choice of either layer has advantages and disadvantage in terms of scaling and costs. The ‘layers’ refer to how you configure an IT network, and the standard for network communications called the OSI model. Layer 2 and Layer 3 refer to different parts of IT network communications. Since this site gets a broad audience with a wide range of technical skill levels, let me take a moment to describe what Layer 2 and Layer 3 mean, for anyone who does not know. I will warn you up front that this article is going to be a tad technical, so bear with me.
