TCP Server, a feature of the WANsuite product line, provides connectivity
to multiple endpoints by associating a TCP port with each endpoint while
reducing the number of physical connections at the central site to one
10/100Base-T Ethernet port.
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 WANsuite 7205’s 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 feature of the WANsuite 7205 provides a company with a layer
of security 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
WANsuite 7205 can simplify your network architecture by allowing you to
bridge separate LANs across a WAN so they operate as a single LAN.
The WANsuite 7205 gives service providers and enterprise customers the
capability to monitor end-to-end network performance (with support for up
to 256 virtual circuits) as well as the capability to verify Service Level
Agreements (SLAs); isolate performance problems to the LAN, local loop or
frame relay network; determine appropriate bandwidth needs; and monitor
network trends to aid in future capacity planning.
