The Switchcraft Family |
|
 |
|
|
| Switchcraft is a robust,
lean, high performance layer 2 services implementation for
embedded OSes such as Linux, VxWorks® and VxWorks AE. Its core engine is responsible
for establishing fast path switching between various network
interfaces in the system, and is designed to take advantage of
hardware acceleration provided by a custom ASIC, network
processor or FPGA based systems. It is implemented as a
component plug-in for Linux and VxWorks and requires no changes
to the kernel or network device drivers. The suite comprises of
a set of highly configurable, small-footprint components,
including link aggregation, load-balancing, fail-over (LACP/
802.3ad), port-security (802.1X) and various flavors of STP
(Spanning Tree Protocol). Components that implement other IEEE
802.n standards including VLAN tagging, GVRP and IGMP snooping
are currently under development. Please contact us for advance
information regarding these products. |

Merlink -
LACP and Link Aggregation |
|
Merlink, a member of the Switchcraft family of layer 2
protocol products, is a high performance implementation of
managed link aggregation for embedded switching
implementations in networking and industrial equipment. It
enables multiple links to be aggregated together to form a
link aggregation group that a MAC client can treat as a
single higher-speed link ("fat pipe") with built-in fault
tolerance. Merlink also enables aggregates to use custom
distribution functions for load balancing and other
application-specific features, including designating
certain ports as fail-over ports. For automated management
of aggregated links in highly interoperable manner,
Merlink includes support for the IEEE 802.3ad Link
Aggregation Control Protocol (LACP) and the Marker
protocol.

X-Calibur -
802.1X |
|
X-Calibur
is an embedded and highly interoperable
implementation of the IEEE 802.1X protocol which provides
secure and flexible authentication in wired and wireless
switches. It adds access authentication services to a
supplicant or an authenticator in any scenario where one
can abstract out the notion of a “network access port”,
such as authenticated Ethernet networks and wireless (WLAN)
networks. It includes both an authenticator and
supplication Port Access Entity (PAE) and is validated for
standalone use and for use with Wired Equivalence Privacy
(WEP) and Wireless Protected Access (WPA) mechanisms in
WiFi® networks. X-Calibur's small footprint and extensive
support for various authentication mechanisms are ideally
suited for use in enterprise and infrastructure oriented
wired and wireless switches, gateways and access points.

Spantasmic -
Spanning Trees |
|
Spantasmic
is a flexible embedded implementation of the
Layer 2 spanning tree protocol (STP) and enhancements for
rapid recovery of connectivity (RSTP – IEEE 802.1W) and
VLAN-sensitivity (MST – IEEE 802.1S). It enables interoperable network redundancy on networking and
industrial equipment such as bridges and switches, or in
embedded switching frameworks within specialized embedded
applications. It also includes a bridging framework with
built-in forwarding and an address resolution logic-based
filtering database which can optionally stand-in for a
switch fabric chipset implementing similar functionality.
Seamless integration with native OS driver models
and standard MIB capabilities for any SNMP agent make
Spantasmic an excellent fit for managed embedded
environments.
