LBCS™ CORBA®/lbcp™ Network Service

LBCS™ CORBA®/lbcp™ is offered as a service and is not delivered as a computer program by logix-tt. The client part of LBCS™ CORBA®/lbcp™ is implemented in LBCS™ Client Firmware.

See: lbcs2 Technical System Description

CORBA® gateway with mux/demux

LBCS™ implements a CORBA® 2.4 gateway with features, CORBA® usually does not offer. This gateway includes multiplexing/demultiplexing semantics, which can be used to easily implement user defined scalable network services in the backend by addressing mobile devices in groups and having calls of CORBA® methods on groups of devices.

lbp™ Protocol Stack offers very lean communication and scalability

Additionally to and in combination with the TCP/IP stack, LBCS™ offers the lbp™ protocol stack, which implements very lean and cheap communication in telephony networks. For example, you can have an RPC, which is transmitted via SMS, and the results are transmitted via UDP/IP/GPRS, holding one session to the device.

Hard cryptography in transport layer

lbp™ offers hard cryptography in transport layer: already in lbp™ v.1 there was Twofish in OFB mode and SHA1. In lbp™ v.2 now AES, Twofish in counter mode and RIPEMD-160 are used.

The implementation includes a validation concept for client devices, so it can be controlled, which devices can be used online (DRM).

Portability

LBCS™ Client implements a firmware concept based on different operating systems. LBCS™ Client Firmware can be implemented anywhere, where POSIX, ISO C++, NMEA and, when needed, wxEmbedded are available. A POSIX layer for Windows CE™, Windows Mobile™ and Windows XP™ Embedded is available, so also Microsoft® Windows™ matches these criteria. LBCS™ Client therefore can be implemented on i.e. eCos, Windows™ Mobile, GNU/Linux, vxWorks™ and on any other RTOS, where these interfaces are available. If there is no operating system on a hardware platform yet, eCos easily can be used to implement LBCS™ Client Firmware.

RIOT™: high scaling network processing by logix-tt

The LBCS™ server platform is constructed using logix-tt's RIOT™ framework for high scaling network processing. RIOT™ is a framework for asynchronous I/O, which dispatches I/O requests on CPU pipes, called partitions.

RIOT™ offers high scalability by excluding synchronous I/O drawbacks like locking problems and thread waiting. RIOT™ is implemented using the standards compliant POSIX.1-2001 aio API.
