The NetStack/RT Family |
|
 |
|
|
The TCP/IP protocols have
been designed to operate over nearly any underlying local or
wide area network technology. Although certain accommodations
may need to be made, IP messages can be transported over a wide
variety of physical layer and link layer technologies. However,
with the proliferation of new technologies, there are
ramifications of using the same design for every type of
application and the efficiency of the TCP/IP stack varies for
various applications. For many applications, the stack is
proving to be a bottleneck due to various design and
implementation constraints. Further, with the leaps being made
in silicon speed and flexibility of hardware design, it is
desirable to exploit the new features in embedded systems
hardware while at the same time working transparently with
networking applications written for a purely software network
stack.
The NetStack/RT family of products is architected as an embedded solution from the
ground up, and introduces new design breakthroughs to work
around latency issues plaguing many implementations, using
advanced buffer management & packet loss avoidance techniques
and exploiting the fill power of multi-threaded operation. |

NetF1 |
|
NetF1
is a high performance, feature rich and
hardware-acceleration capable embedded TCP/IP stack
implementation with an included virtual routing framework.
It includes a complete implementation of multi-instance
capable TCP, UDP, IP, IPv6, ICMP, and IGMP designed
specifically for use in low-resource embedded
environments, where unused stack components can be scaled
out or replaced with hardware equivalents. With full
support for host and IPv4 / IPv6 router mode, NetF1 offers
a superset of capabilities provided by many other
host-only or router-only stacks including unnumbered
interface support and interface identification for
send/receive. This extensive feature-set does not come at
the expense of performance either -- higher performance,
binary compatibility with existing drivers and
API-compatibility with existing socket based network
applications are just a few reasons where NetF1 outpaces
its peers. Further, it also includes the ability to
optionally create highly multi-threaded multiple isolated
and managed virtual "routers" in a single physical system
thereby lending itself to use in embedded environments
that need to separate out network backplane communication,
or in ISP equipment that needs to support multiple routing
protocols for multiple customers.

GrandPPPrix |
|
GrandPPPrix
is a robust,
standards-based embedded implementation of the
Point-to-Point Protocol (PPP), Multi-Link PPP (ML-PPP or
MP), and Multi-Class Extensions to MP (MCMP). It
includes the core components required to implement
advanced, secure PPP in an embedded device to facilitate
multi-protocol communication using single or multiple
independent point-to-point links. With built-in support
for prioritization, it also provides efficient transport
of multimedia traffic and minimizes end-to-end delays.
GrandPPPrix’s flexible compression, authentication, and
encryption over diverse physical transports are ideal
for use in constrained embedded environments.
