The core software technology of the ZX7100 goes far beyond simple
Ethernet switch management. As a full-featured embedded Linux
distribution, OpenArchitect supports user applications running in
the industry-standard Linux environment. From the point of view of
the technician, an OpenArchitect switch appears as a stand-alone
Linux system with all the familiar tools and utilities. Users that
know how to configure Linux networking systems can become
proficient with an OpenArchitect switch within minutes.
While the OpenArchitect philosophy is
to enable the use of open-source software as much as possible,
the key to this technology is the proprietary core virtualization
structure developed exclusively by ZNYX Networks. More than 7
years of continuous development and deployment have made
OpenArchitect 3 the most robust and full-featured embedded
Ethernet control software.
PowerPC Embedded System
The ZX7000's embedded processor is the Freescale
MPC8270VR, which combines a high degree of density with low power
consumption and significant processing capability.

Linux Routing Platform
A significant advantage of
OpenArchitect is its ability to use any routing protocol stack
that runs in the Linux environment. The standard release of
OpenArchitect includes the gated daemon, which drives OSPF, RIP,
EGP and BGP. Other protocol stacks, open-source or proprietary,
may be easily re-compiled with no source code changes to run on
OpenArchitect. Other embedded switch architecture solutions
require customization of routing code to a proprietary API. Only
OpenArchitect uses Linux open APIs, enabling true transparency and
flexibility for network architecture integration.
Layer 2 - 7 Packet Classification
One of the ways in which the ZX7100
with OpenArchitect expands the envelope is its ability to do
line-rate packet classification from layer 2 through layer 7. This
feature can often eliminate the need for an expensive external
security device by providing IP filtering capability, or it can
manage traffic by assigning specific packets to different VLANs,
Classes of Service, or separated for special processing. As with
other features of OpenArchitect, the interface to program the
packet classification uses familiar Linux commands.
The advanced OpenArchitect 3 packet
classification feature may be used to implement load balancing,
where packets are distributed among ATCA blades based on their
content. This feature enables true scalability for ATCA
applications, and can be adapted according to any user-set policy.
The switch silicon handles the distribution of packets at full
line rate, giving the ZX7100 a significant advantage over
processor-based load-balancing schemes.
To support larger applications, the
ZX7100 includes a CompactFlash socket that can support a FlashROM
device or a micro disk drive, in addition to the embedded
processor's Flash ROM. This feature can be used to manage software
upgrades, or provide bulk storage for system logs and other
purposes. For security, the CompactFlash cannot be removed without
removing the ZX7100 from the ATCA chassis.
The front panel of the ZX7100 includes
a USB socket that enables inexpensive, industry-standard
expandability. Any Linux compatible peripheral device may be used
for a variety of application enhancements, such as one-step
upgrades and inline diagnostics.
Rear Transition Module
For applications that use rear-panel
I/O, the ZX7100 may be used with an RTM. Up to six in-band
Ethernet channels are provided, as well as two out-of-band RS-232
ports and two out-of-band 10/100 Ethernet ports.
The ATCA Zone-3 connector of the
ZX7100 provides full connectivity for the ATCA backplane clock,
which permits the implementation of a chassis backplane clock
feature. A custom RTM may host a hardware-based clock generator to
meet any ATCA-compatible specification that requires telco-grade
OpenArchitect® HA Suite
OpenArchitect HA Suite features
transparent port-to-port, VLAN-to-VLAN and switch-to-switch rapid
failover. With the OpenArchitect High Availability (HA) software
suite, the chassis can respond and automatically correct any
single point of failure.
