openNet Server (BS2000)

The communication manager of BS2000

Current versions: V21.0, V4.0

“Open networking” is the term used to describe the connection between BS2000 and the different data communication systems. The basic component of open networking in BS2000 is the selectable unit openNet Server (short designation: ONETSERV (BS2000)), which is in turn made up of several products, including BCAM, DCAM, etc. In the context of openNet Server (BS2000), the transport system has been systematically expanded into a communication manager.

openNet Server (BS2000) comprises the products BCAM, DCAM, CMX and SOCKETS (with their specific user program interface) and also the products IPSec and IKED to the encodet transfer of the user-data, LWRESD for the access on DNS-Server, VTSU-B for the support of logical terminals and XHCS to transformation signs between differently codes-sets. The user program interfaces enable individual data communication applications to be implemented. A standardized trace concept supports the implementation and operation of user programs.

Proof of IPv6 capability through fulfillment of the IPv6 Ready Logo program. This validates the RFC-compliant implementation of the IPv6 protocol stack and inter-operability with IPv6 stacks of other manufacturers. openNet server awarded the IPv6 Ready Logo in gold. Actually awarded for V3.6; V 4.0 is in preparation.

Implements the transport functions in the host computer within BS2000 open networking. In conjunction with High-speed Net Connect (HNC), fault-tolerant network topologies can be implemented as part of redundancy configurations.

DNS connection
The names and addresses of the partner systems connected to BS2000 can be stored in external DNS servers for easy and consistent administration. BCAM can access the DNS server, which provides the conversion of names to addresses and vice versa, using the supplied LWRESD product.

Supports the use of cryptography in layer 3 (network or switching layer) of the OSI reference model. IPSec offer the authentication of the communication partners, just as the encoding of the user-data.

The IPSec implementation in product openNet Server supports the automatic key exchange via 'Internet Key Exchange' protocol IKEv1 and IKEv2.

Makes the NEA or ISO transport service available to its user program interface using convergence protocols - via all three communication protocol stacks (NEA, ISO, TCP/IP).

Is used for logical support of terminals and terminal printers in "line/page mode". FHS may be used in addition for "format mode."

Represents the transport access system and has a user program interface (ICMX), as well as using the services of the BCAM transport system.

Makes the TCP transport service and the runtime environment available for user applications.

Offers the necessary information on all character sets for all comparison and conversion operations. The XHCS interfaces are also available to every user program.
