Smart
Processing is 3Com’s commitment to
providing the lowest total cost of network
ownership by offering robust yet simple
LAN-to-WAN solutions.
Smart
Processing
transforms today’s complex WAN access
into secure, scalable integrated IP-based
solutions that deliver:
n
Security
— Seamless access to public
or private networks while preserving
network integrity.
n
Control
— Powerful Web-based applica-
tions for simplified network management.
n
Scalability
— Simple remote office
connectivity with predictable network
performance and future growth capabilities.
n
Availability
— Embedded reliability
to meet the service requirements of
every business.
3Com’s powerful NETBuilder products let you implement any combination
of LAN and WAN connections to meet your needs (see diagram below).
IBM SNA Connections
To accommodate legacy SNA
traffic, NETBuilder II software
uses DLSw Version 2 (RFC
2166) to encapsulate SNA
traffic and transport over IP
networks. Direct attachment of
PU T2 (SDLC) controllers is sup-
ported as well as many other
legacy devices and protocols.
NETBuilder II DPE EZBuilt Systems
The DPE EZBuilt System includes
the NETBuilder II chassis, DPE
module, and a 20 MB Flash card
pre-loaded with the Extended WAN
software package.
Extending Network Reach with 3Com’s
Boundary Routing System Architecture
3Com’s Boundary Routing
®
system architecture lets you
add remote sites to your network without adding com-
plexity or administrative costs.
The system works in small to midsize remote
offices having one LAN segment and one active WAN con-
nection to a main site. Boundary Routing architecture
delivers complete routing functionality to each remote
location, easily and affordably. Installing a router at the
remote site becomes a plug-and-play operation. Software
updates and configuration changes are handled transpar-
ently over the WAN by a NETBuilder II
®
router or any
other central-site capable NETBuilder
®
routing platform
at the main site. Centrally located administrators manage
the routing complexity for many remote sites.
Included in the Boundary Routing solution are the
SNA boundary routers. These routers provide the same
functionality as the other boundary routers, but have
been optimized for SNA traffic. The routing architecture
automatically prioritizes SNA traffic over other protocol
traffic providing predictable SNA performance.
With its cost-saving and time-reducing benefits,
Boundary Routing architecture is the ideal choice for
leveraging administrative expertise in growing
organizations.
Data Compression
3Com’s history-based or per-
packet link compression reduces
the size of both headers and
data in packets sent over serial
lines, letting the lines carry two
to four times as much traffic at
no additional charge. With the
DPE, the second processor is
dedicated to data compression
leaving the main processor to do
packet processing.
NETBuilder II WAN Extender for ISDN
or Channelized T1/E1
The T1 version supports 23 channels on each of
two interfaces and the E1 version supports 31
channels per interface to support the ISDN
Primary Rate Interface (PRI), Switched 56 (not on
E1), or channelized connections.
