Network Diagram Software Logical Network

ConceptDraw Network Diagram is ideal for network engineers and network designers who need to draw Logical Network diagrams.

Cisco Network Templates

Cisco has a huge number of enterprise clients in the corporate environment. Therefore many network engineers should draw network diagrams for Cisco hardware.
ConceptDraw has Cisco network diagram templates:

Wireless Mesh Network, Network Organization Chart, Roaming Wireless Local Area Network, Cisco ISG Topology Diagram, Cisco Express Forwarding Sample that facilitates drawing at the initial stage.

However for customizing Cisco network diagrams you can use 13 Libraries like this: Cisco Basic, Cisco Buildings, Cisco IBM, Cisco LAN, Cisco WAN, Cisco Media, Cisco Optical, Cisco People, Cisco Routers, Cisco Security, Cisco Switches&Hub, Cisco Telepresences, etc.

This take great advantage to you for designing Cisco network diagram templates.
"There are two definitions for wireless LAN roaming:
Internal Roaming (1): The Mobile Station (MS) moves from one access point (AP) to another AP within a home network because the signal strength is too weak. An authentication server (RADIUS) performs the re-authentication of MS via 802.1x (e.g. with PEAP). The billing of QoS is in the home network. A Mobile Station roaming from one access point to another often interrupts the flow of data among the Mobile Station and an application connected to the network. The Mobile Station, for instance, periodically monitors the presence of alternative access points (ones that will provide a better connection). At some point, based on proprietary mechanisms, the Mobile Station decides to re-associate with an access point having a stronger wireless signal. The Mobile Station, however, may lose a connection with an access point before associating with another access point. In order to provide reliable connections with applications, the Mobile Station must generally include software that provides session persistence.
External Roaming (2): The MS (client) moves into a WLAN of another Wireless Internet Service Provider (WISP) and takes their services (Hotspot). The user can independently of his home network use another foreign network, if this is open for visitors. There must be special authentication and billing systems for mobile services in a foreign network." [Wireless LAN. Wikipedia]

"A wireless network is any type of computer network that uses wireless data connections for connecting network nodes. Wireless networking is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure. Examples of wireless networks include cell phone networks, Wi-Fi local networks and terrestrial microwave networks." [Wireless network. Wikipedia]
