Integrators’ Reference Manual for ViewStation EX, ViewStation FX, and VS4000

LAN/WAN Considerations

You will need to develop a network topology checklist that includes the following information:

❑List of Networks: To take advantage of least cost routing and alternate routing, you must define the topology of the Local area networks (LANs) that each gatekeeper serves, as well as the LANs that are logically connected to these but served by other gatekeepers. This allows the gatekeeper to determine how IP traffic is routed from one endpoint to the next. PathNavigator uses the network topology to determine when resources are unavailable so that an alternate (ISDN) path can be determined.

❑Subnets within each network and subnet IP address: A network address is the equivalent of a subnet. You will need to define all subnet addresses within your LAN. If this information is not available to the gatekeeper, calls may be rejected because no route can be determined.

❑WAN links: These are logical connections from one LAN to another LAN within the WAN cloud, or logical connections from one network to another network outside of the organization. The two types of WAN links are the dedicated WAN link, which is a logical connection via a dedicated link, leased line, frame relay or though an ATM network; and the WAN link to other networks through a VPN tunnel, which connects one network to another through a secure connection over the Internet.

❑Network Diagram describing how networks are connected and bandwidth capacity on each WAN link.

Each gatekeeper will need information about its neighbor gatekeepers to be able to communicate with them. Neighbor gatekeepers manage other H.323 zones within an organization and allow the network’s workload to be distributed across logical boundaries within the organization. This enables more efficient use of the network by limiting communication between zones (across WAN links). When a call originates with one gatekeeper's zone and that zone's gatekeeper is unable to resolve the dialed address, it will be forwarded to the neighbor gatekeepers for resolution. The port used for gatekeeper-to-gatekeeper communication is usually 1719.
