for IP Packet routes. After building the routing tables, the unit periodically
broadcasts the contents to neighboring routers so your network can choose the
most efficient routes available.
OSPF uses link-state routing algorithms to calculate routes based on the
number of routers, transmission speeds, delays, and route costs. Using the
OSPF protocol, the WANsuite 6450 works with other routers in your
telecommunications fabric to dynamically change routes “on the fly” to make
use of the most efficient and cost-effective transit across your network.
Bridging separate LANs together is another option for the IP traffic. Using the
IEEE Standard 802.1D Transparent Bridging specification, the WANsuite
6450 can simplify your network architecture by allowing you to bridge
separate LANs across a WAN so they operate as a single LAN.
Because IP Gateway enables the WANsuite 6450 to route IP traffic either
statically or dynamically or to bridge IP traffic across your LAN/WAN
architecture, your need for costly routers is substantially reduced. This one-
stop solution can help you meet the requirements of your many different
applications.
DHCP uses a server-client architecture to assign IP Addresses to PCs and
workstations on the LAN. The DHCP server dynamically assigns these IP
Addresses, which can be either temporary or permanent, to each PC or
workstation (DHCP client). These IP Addresses are "housed" on the DHCP
server. The flexibility to reassign IP Addresses saves the end user money by
eliminating the need for a single IP Address for each piece of equipment on
the LAN.
NAT enables an enterprise to set up two sets of IP Addresses
−
one set for
internal network use (or LAN traffic) and one set for external use (or Internet
traffic). This can provide a layer of security for a company by eliminating
outside access to internal IP Addresses from the Internet.
The WANsuite 6450 gives service providers and enterprise customers the
capability to monitor end-to-end network performance (with support of up to
16 virtual channels); isolate performance problems to the LAN, local loop, or
ATM network; determine appropriate bandwidth needs; and monitor network
trends to aid in future capacity planning.
All of the WANsuite 6450’s installation, performance configuration, traffic
monitoring, alarm reporting, and diagnostic capabilities can be configured
through the unit’s embedded Web server interface (WANsight™) using
Microsoft
®
Internet Explorer™. The Web server interface can be accessed
locally through the Ethernet port or the Supervisory port, or remotely through
the Network port. Especially advantageous is WANsuite’s advanced
monitoring and control capability that gives network administrators the ability
to plan future capacity requirements.
The unit’s built-in Service Aware technology lets network managers maximize
available WAN bandwidth and verify SLAs. This management platform lets
the end user see network activity (performance) and problems (diagnostics) on
any permanent virtual circuit (PVC), access line, or physical circuit.
