MontaVista Linux Carrier Grade Edition
|
| MontaVista Linux Carrier Grade - High Availability, Field Serviceability and Real-Time Performance |
 |
MontaVista Linux Carrier Grade Edition 5.0 is a commercial-grade Linux development platform for developers working with RAS (reliability, availability, and serviceability) managed hardware (HPI, IPMI) or custom hardware, who require long-term support and high availability.
Carrier Grade Edition 5.0 provides the time-to-market benefits normally only found in proprietary development platforms with the customizability and control of an open source Linux environment.
|
 The heart of MontaVista Linux Carrier Grade Edition 5.0 is an embedded Linux operating system designed for telecom and network equipment, including ATCA- and MicroTCA-based platforms, such as SGSNs, GGSNs, and softswitches. Because Carrier Grade Edition 5.0 supports Linux standards, designers can add functionality by including off-the-shelf Linux utilities without worrying about function loss due to incompatibility.
MontaVista Linux Carrier Grade Edition 5.0 includes features only available from MontaVista, including new field-serviceability features that give field engineers the ability to fix and upgrade live systems while they are running with little or zero downtime. Unlike non-commercialized open source code, MontaVista Linux CGE is a field-proven production-quality operating system, has been integrated, tested, and debugged by MontaVista's testing facilities, and is supported by MontaVista's experienced support organization.
New Carrier Grade Edition 5.0 also includes a development environment that enables engineers to more quickly design new equipment and applications. MontaVista Linux CGE provides reliability, scalability, and real-time performance proven in the field by major voice and data carriers. |
| A Complete Development Platform |
| |
Run-Time Application Patcher |
Available only from MontaVista, the Run-Time Application
Patcher gives field engineers the ability to apply a binary patch to a
live system while it runs, without incurring any downtime. Engineers can
update software, fix bugs, and add new features to a live system without
stopping it or rebooting. |
|
| |
| |
Flight Recorder |
When a system fails today, field engineers must wait until
the next failure to investigate the first one. Engineers have no way of
gathering enough data about what happened before and during a crash to
conduct an effective post-crash diagnosis and take corrective action. CGE
5.0 includes new Flight Recorder, which acts like an airplane black box to
track and log system history. It keeps a scheduler history, which provides
more information than a crash dump snapshot, and is user-extensible for
customized tracking. |
|
| |
| |
Field-Safe Application Debugger |
When issues arise in a live carrier grade system, bringing
the system offline for debugging is not acceptable. MontaVista Field-Safe
Application Debugger debugs a live system without halting execution or
affecting services. A field engineer logs into a live system, uses the
debugger to set tracepoints, and logs out. The debugger collects execution
information and stores it for later retrieval. The debugger's small memory
footprint and limited CPU usage have minimal impact on the live system,
providing debugging without obstruction, and enabling critical processes
to remain online and running to provide the high availability that
carriers require. This capability, available only from MontaVista, has
been enhanced and is easier to use. |
|
| |
| |
Live application core dump |
When field engineers need to perform a core dump to help
them debug problems on a running application, MontaVista's live
application core dump dramatically reduces the downtime required to make a
core dump. With only a short (generally tens to hundreds of milliseconds)
stop of the application, this new feature takes a snapshot of the running
application. The application can continue running while engineers debug
the snapshot to fix the application. MontaVista is the first to offer this
capability. |
|
| |
| |
Transparent Inter-Process Communication
(TIPC) |
Designed for clustered computer environments, the TIPC
cluster communications protocol allows designers to create applications
that can communicate quickly and reliably with other applications
regardless of their location within a cluster. Using TIPC, a process can
send messages to a service without having to know the location of the
service; so the service location can move. TIPC also provides a basic
membership handling to know which nodes are and are not available in the
cluster. |
|
| |
| |
Integrated real-time response |
Carrier Grade Edition 5.0 is 100% native Linux with
real-time performance features, including MontaVista enhancements plus
integrated high resolution nanosecond timers (hrtimers) Additional
real-time features include fast mutexes, threaded soft and hard IRQ
handlers, and application-level priority inheritance and queuing,
providing preemption response latency as low as 50 microseconds. Benchmark
tests have proven that MontaVista's integrations of real-time features
deliver much lower latency levels than non-MontaVista
implementations. |
|
| |
| |
Microstate accounting |
For the first time in a commercial Linux product, engineers
can accurately measure process and thread utilization on a CPU. CGE 5.0
performs high-resolution process accounting, so applications can be
monitored to anticipate and prevent CPU overload situations. This enables
engineers to design automated load balancing and graceful protocol
degradation using reliable and accurate CPU load numbers. Engineers can
accurately monitor and precisely predict CPU loads, increasing the
accuracy of worst-case planning, preventing downtime, and reducing the
purchase of backup equipment for traffic surges. Older systems report CPU
and thread activities based on statistical sampling estimates, which can
be very inaccurate, instead of the actual measurement now enabled by
microstate accounting. Microstate accounting in CGE 5.0 will improve the
scalability, reliability, and cost of carrier networks. |
|
| |
| |
Integrated development environment |
Carrier Grade Edition 5.0 includes new runtime components
that integrate with MontaVista DevRocket, an Eclipse-based IDE with
development tools that enhance productivity for both kernel-level and
application-level engineers. Integrated memory leak detection, performance
profiling, memory usage analysis, and system tracing combine to accelerate
system development and maintenance, and increase system
availability. |
|
| |
| |
Multicore and SMP support |
Carrier Grade Edition 5.0 supports both single-core and
multicore processors, and supports equipment built with multiple
processing chips as well as synchronous and asynchronous multiprocessing
on integrated chips. |
|
| |
| |
Carrier standards compliance |
MontaVista Linux CGE 5.0 is compliant with Carrier Grade
Linux Specification 4.0 from the Linux Foundation as well as LSB 3.0
compliant. CGE 5.0 is also compliant with the SCOPE Alliance Linux
Profile, and runs on hardware designed to support the PICMG Advanced
Telecommunications Computing Architecture (ATCA) and MicroTCA
specifications. CGE 5.0 supports Intel's Extensible Firmware Initiative
(EFI). |
|
| |
| |
MontaVista's carrier grade partners |
Oracle, MySQL, Enea, VirtualLogix, and more than 70
additional MontaVista partners provide middleware, applications, and tools
ready to use in carrier grade network equipment with MontaVista Linux
Carrier Grade Edition. |
