Dax DX-2801 is an all-in-one enterprise class router that
can connect your multiple remote offices over a public network. It
supports all the latest standards and protocols in order to serve voice, dynamic
routing, security, network management, bandwidth sharing and video in order to
meet the requirements of multiple application needs.

The device is powered by a 266 MHz processor, 128 MB SDRAM
upgradeable to 256 MB, 8 MB flash memory that's upgradeable to 72 MB. The
device has four network modules, in which two are Ethernet fixed ports and one
serial (Sync/Async) ISDN BRI U Fast Ethernet module that connects to your ISDN
line. To manage and configure the device, it has one console port that can be
directly connected to a PC's RS232 port. The device can also interconnect
offices on an Ethernet-based ADSL connection. The router offers VPN
functionality that has support for Standard and extended ACLs, TACACS, RADIUS,
NAT, IP packet filtering, L2TP and GRE functionality, this gives you a secure
VPN tunnel into your organization network. It also has authorization and
accounting parameters (PAP/CHAP, TACACS, and RADIUS). For advanced security, it
supports Encryption (40-bit and 56-bit pay load) and IPSec DES/3DES/AES.
The device supports almost all routing products in the
market and also supports an array of industry standard IP-routing protocols. On
the QoS front, the router uses queue management and scheduling techniques such
as PQ, FIFO and WFQ to provide guaranteed bandwidth to your running network
services. Bandwidth optimization is another key feature of this device; it
includes DDR (dial-on-demand routing), BOD (bandwidth-on-demand ), compression
and filtering to reduce WAN bandwidth cost. To check the performance, we tested
this router between two physical networks over an IP network where both were
connected via a 100 Mbps switch. Then we ran NetIQ's Qcheck to measure its
sustained throughput data transfer, streaming rate and response time. The router
gave us a sustained throughput of 67 Mbps on transferring 1000 kBytes of payload
from one end to another. Its response time was 1ms. In the streaming test the
router gave 997.24 Kbps with 1000 Kbps streaming data payload. There was
0% data loss in the process. Going by the scores, the device did very well in
our tests.
Bottom Line: If you're looking for a feature-rich
router, this is a good choice.
