Troubleshooting Frame Relay networks isn't any harder than troubleshooting any other type of network as long as you know what to look for, which is what I'm going to cover now.
Virtual Private Networks - 0 views

I'd be pretty willing to bet you've heard the term VPN more than once before. Maybe you even know what one is, but just in case, a virtual private network (VPN) allows the creation of private networks across the Internet, enabling privacy and tunneling of non-TCP/IP protocols.

SSIDs, WEP, and MAC Address Authentication - 0 views

SSID is a common network name for the devices in a WLAN system that create the wireless LAN. An SSID prevents access by any client device that doesn't have the SSID. The thing is, by default, an access point broadcasts its SSID in its beacon many times a second. And even if SSID broadcasting is turned off, a bad guy can discover the SSID by monitoring the network and just waiting for a client response to the access point.

Simply put, IPSec is an industry-wide standard suite of protocols and algorithms that allows for secure data transmission over an IP-based network that functions at the layer 3 network layer of the OSI model.
Configuring Quality of Service (QoS) across Our VPN Tunnel - 0 views
-
QoS is actually more secure, cost effective, even faster in today's networking environment! This is why I'm going to show you how to configure QoS on our VPN serial link-a great place to configure QoS in a production network, by the way.
MESH and LWAPP - 0 views
-
As more vendors migrate to a mesh hierarchical design, and as larger networks are built using lightweight access points, we really need a standardized protocol that governs how lightweight access points communicate with WLAN systems. This is exactly the role filled by one of the Internet Engineering Task Force's (IETF's) latest draft specification, Lightweight Access Point Protocol (LWAPP).
Open Access - 0 views
-
All Wi-Fi Certified wireless LAN products are shipped in "open-access" mode, with their security features turned off. While open access or no security may be appropriate and acceptable for public hot spots such as coffee shops, college campuses, and maybe airports, it's definitely not an option for an enterprise organization, and likely not even adequate for your private home network.

Introduction to Wireless Technology - 0 views

Wireless LANs (WLANs) use radio frequencies (RFs) that are radiated into the air from an antenna that creates radio waves. These waves can be absorbed, refracted,or reflected by walls, water, and metal surfaces, resulting in low signal strength.
