Method for optimized processing of connections conducted outside a switching center
View Patent ↗The method enables optimization of the processing of connections conducted outside a switching center in peripheral devices of a switching system, which provide no HW-orientated tasks on their peripheral devices assigned in switching terms. The operating system of the peripheral device and the security engineering running thereon permit quasi-parallel processing of a multiplicity of virtual peripheral devices. It is thereby possible to address every virtual peripheral device with a dedicated logic address via the message interface of the physically assigned peripheral device.
1. A method of optimized processing of connections conducted outside a switching center in peripheral devices of a switching system, which provide no hardware oriented tasks on the peripheral devices assigned in switching terms, which comprises permitting with an operating system of the peripheral device and security engineering running thereon quasi-parallel processing of a multiplicity of virtual peripheral devices, and addressing virtual peripheral devices with a dedicated logic address via a message interface of the physically assigned peripheral device.
2. The method according to claim 1 , which comprises distributing messages within the peripheral device with a central operating system section on the basis of a destination address, co-supplied via the message distribution system, of a virtual peripheral device.
3. The method according to claim 1 , which comprises distributing messages to virtual peripheral devices via flexibly loaded routing tables of the message distribution system.
4. The method according to claim 1 , which comprises administering a number of the virtual peripheral devices per peripheral device in dependence on performance, message interface, amount of memory, and application.
5. The method according to claim 1 , which comprises supporting a loading of software into a virtual peripheral device via a same physical message channel of the assigned peripheral device.
6. The method according to claim 1 , which comprises, in a case of permanent total failure of a peripheral device, updating the routing tables of the message distribution system, and then loading a reserved peripheral device with a program and data of the failed virtual peripheral devices and taking the reserved peripheral device into operation automatically without reacting on the further devices of the switching system.
7. The method according to claim 1 , which comprises rescuing stable connections for duplicate-design peripheral devices or 1:1 redundant unduplicated peripheral devices, simultaneously updating the switching data memories and states of the virtual peripheral devices of the redundant unit per logic updating channel or updating channel physically present in the peripheral device.
