ah OK, so in this case if a company grows big and requires more switch port due to the many VLANs in use, they use Layer -3 switch ?
</div>


<div>
so what about layer 4 switch ? do they separate the traffic between TCP and UDP ?
</div>


<div>
There's really no such thing. &nbsp;Like I said before, any switch that operates above layer 3 is a content switch.

<div>
Ah Ok, so does this means that content switch is almost the same as load balancer like Citrix NetScaler device ?

Hi All,<br />
<br />
AFAIK, switch typically operates at OSI layer 2 while router operates at layer 3, so I wonder what are the differences in between the Switch which has the layer 2-3-4-5-6-7 switching ?<br />
<br />
can someone explains to me ?<br />
<br />
Thanks.

Switch layer differences and usage ?

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Networking Hardware-Other

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
