monitoring and control capability that gives network administrators the
ability to plan future capacity requirements. To extend the WANsuite 5370’s
functionality even further, Verilink offers an element management software
system for reporting and real-time diagnostics.
The unit’s built-in ServiceAware™ technology allows network managers to
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.
Verilink’s FrameStart™ technology is standard with the WANsuite 5370 and
benefits the initial installation of frame relay circuits by eliminating the
requirement for a frame relay test set. FrameStart ensures that DDS circuit
status, signal quality, loopback code detection, access link condition, and the
various Layer 2 frame relay investigation and reporting features are available
and accurate.
Another feature of the WANsuite product line, IP Gateway enables IP
packet routing throughout a LAN/WAN network architecture using static
routing configurations or dynamic routing protocols (Routing Information
Protocol
−
RIP 1 and RIP 2
−
or Open Shortest Path First
−
OSPF).
RIP 1 and RIP 2 allow routers to exchange routing information. WANsuite
then uses this information exchange to build routing tables for IP Packet
routes. After building the routing tables, WANsuite periodically broadcasts
the contents to neighboring routers so that 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, WANsuite works with other routers in your
telecommunications fabric to dynamically change routing “on the fly” to make
use of the most efficient and cost-effective transit across your network.
Because IP Gateway enables WANsuite to route IP traffic either statically or
dynamically across your LAN/WAN architecture, your need for costly routers
is substantially reduced. WANsuite is a one-stop solution that 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.
Bridging separate LANs together is another option for the IP traffic. Using
the IEEE Standard 802.1D Transparent Bridging specification, the
