Green Hills Software’s GateD
suite of Layer 3 routing protocols is a vendor-neutral, comprehensive control-plane
solution that provides complete source-code for Layer 3 protocols. The
scalability of the code, complete functionality, and expansive set of APIs
make the code ideal for inclusion in carrier-grade core, edge, and aggregation
devices.

For over 20 years, GateD has been the standard starting point for anyone
who needed comprehensive software solutions for advanced routing, for
everything from server redundancy to the most scalable, core IP routers.
During that time, hundreds of products have been built and deployed using
GateD, the gold standard in routing technology.
Green Hills, the leader in secure and reliable software, has taken this
proven routing offering and has combined it with the industry’s
most secure operating system—INTEGRITY—and its advanced TCP/IP
v4/v6 host/routing stack, bringing the highest levels of security and
routing together in a processor neutral, integrated and optimized software
suite.
Deploying GateD with the secure separation kernel architecture of the
INTEGRITY operating system enables the highest levels of security for
network devices. INTEGRITY was designed from the beginning with security
in mind, and supports the requirements and security policies of Multiple
Independent Levels of Security (MILS), which is the architecture for
composing secure computing systems from high-assurance components. INTEGRITY
provides protected execution of native applications, guest OS applications
and system services; guaranteed resource allocation; information flow
control between partitions, stack, router, network management and application
isolation, along with containment of errors and attacks. All are essential
components for hardening any networked device against both casual and
targeted, well funded attacks.
Available Layer 3 routing components include GateD RIP, RIPng, OSPF,
OSPFv3, IS-IS, BGP, MP-BGP, and VRRP—the
first suite of routing protocols to have broad IPv6 support. With GateD,
networking device developers can pick and choose from these individual
protocols or license a variety of packages targeted at specific applications,
all integrated, validated and tested with the INTEGRITY secure operating
system and the GHNet IPv4/v6 host/router stack. With this approach, customers
can seamlessly add or reconfigure GateD routing protocols based on changing
system requirements with the highest level of confidence in the shortest
timeframe and at the lowest cost.
The modular design of GateD allows common functionality, data structures,
and APIs to be shared across protocols. From an equipment manufacturer's
perspective, this provides two immediate advantages:
- Additions and modifications to existing APIs at points of integration
have limited effect on the stability of existing protocols. This means
that even major new features can be deployed without anxiety over changes
to long-established, de facto standard code, such as Green Hills' Fast
OSPF and BGP implementations.
- New protocols inherit a high degree of stability and robustness
for the long deployment of standard functions, such as memory allocation,
scheduling, and routing policy.
GateD Layer 3 Routing Protocol Suite includes a wide variety of basic
features on which the protocols rely and which are common across the
range of protocol packages:
- GateD Advanced Management Interface (AMI)
- OS Adaption Layer
- Sophisticated policy engine
- Memory management
- Static route support
- Timer facilities
- Cooperative multitasking
- Checksum generation andverification
- ICMP
- MIBs

Today, the Green Hills GateD carrier-class software suite has the most
complete set of routing protocols in the industry...including OSPF, BGP,
RIP, IS-IS, and Multicast. Green Hills GateD routing software serves
applications far beyond routers, including all intelligent devices that
link to the network and transfer data: LAN switches, wireless access
points, satellites, edge traffic and service aggregation boxes, core
optical switching boxes, firewall and security devices, proxies, caches,
and load balancing.
As network complexity increases, the challenge of providing optimal
routing increases exponentially—as does delivering meaningful ROI.
Customers will benefit from improved product quality and availability,
increased stability and functionality, and substantial improvements in
time-to-market, lower risk, and reduced development cost.
Green Hills seasoned networking experts at its Ann Arbor Networking
Design Center continue to expand upon a complete solution set for its
customers—from a rock-solid code set, to testing and documentation,
APIs and professional services—everything developers need when
making their "build vs. buy" decision.
With a heritage of technological innovation, the longest track record
of successful deployment, and the largest share of the network routing
industry's intellectual capital, no other company is better positioned
to be the first to deliver the next generation of secure networking solutions.GateD
is used by leaders in every major sector of the Internet, including manufacturers
of core routers, access routers, optical equipment, IP telephony equipment,
and service providers.
The Green Hills GateD software is highly portable and available for
a wide variety of platforms.

The GateD Advanced Management Interface (AMI) comes standard with a license
of GateD and consists of two distinct components:
- an API that provides direct access to all configurable options across
all portions of the code, allowing highly scalable, incremental configurations
- an Agent designed for easy integration with any messaging system
available on the control plane OS
AMI's simple, consistent API dramatically improves speed of integration
with any user interface, providing substantial savings in time to market.
When used in conjunction with the AMI Agent, the management plane can
be off-loaded to a separate processor, or even an entirely different
card, removing management overhead from the control plane and improving
efficiency. When combined with Green Hills CLI module, dozens of engineering
years can be saved.

The GateD CLI module comes standard with a GateD license and allows
network equipment manufacturers to develop and deploy new equipment
at unprecedented speeds by removing the largest obstacle to deploying
carrier-class control plane software—the development and integration
of a complete management solution.
