This is what I plan:<br />
FW &lt;--&gt; distibution WAN switch&lt;--&gt; core/distro switch &lt;--&gt; internal network<br />

<br />
Is it better to get a 3750X or a 3560X is sufficient for the distribution WAN? <br />
<br />

Experts,

This is what I plan:
FW <--> distibution WAN switch<--> core/distro switch <--> internal network
                                           |                              |
                                           |--------> core2/distro switch <----> internal network

Is it better to get a 3750X or a 3560X is sufficient for the distribution WAN? 

Thanks

3560X versus 3750X

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

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.

Networking

Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).
