Abstract

In telecommunication networks, most of the Ethernet based access products have only limited feature sets which assure a certain Quality of Service (QoS). For this reason, the access area very often is a bottleneck of the whole network. Till now it has been difficult or expensive to reduce the problem for all existing Ethernet based access products. To solve the problem, a so called Generic Rule Engine for Ethernet based Applications and Services (GREASe) can be utilized. This generic rule engine is a software (SW) module which comprises an algorithm deciding about the hardware (HW) components configuration settings. The GREASe provides all possible application bundles and service bundles including a reusable management interface, a Message Sequence Chart (MSC) catalogue, SNMP (Simple Network Management Protocol) and MIB (Management Information Base). Due to the hardware adaptation layer and the operating system (OS) adaptation layer, this software-package is HW- or OS-independent. How to utilize an embodiment of the GREASe in combination with a DSLAM (Digital Subscriber Line Access Multiplexer) is shown exemplary in Figure 1 and Figure 2. For example, a subscriber A applies for 64Kbit/s VoIP (Voice over IP, Internet Protocol), 20Mbit/s fast internet access and gaming discarding service. To meet this requirement, the rule engine can be integrated in an access product for configuration of the HW-switching components to support the required services. In the example, three applications and service bindings have to be configured - one for VoIP, one for fast internet and one for gaming. The SNMP interface receives a SNMP message from the SNMP agent and calls the Generic Rule Engine to translate these bindings into rules and to configure then the switching HW via the HW adaptation layer.

Generic Rule Engine for Ethernet based Application and Service

Idea: Dr. Walter Kopetzky, DE-Munich; Ligang Tian, CN-Beijing

In telecommunication networks, most of the Ethernet based access products have only limited feature sets which assure a certain Quality of Service (QoS). For this reason, the access area very often is a bottleneck of the whole network. Till now it has been difficult or expensive to reduce the problem for all existing Ethernet based access products.

To solve the problem, a so called Generic Rule Engine for Ethernet based Applications and Services (GREASe) can be utilized. This generic rule engine is a software (SW) module which comprises an algorithm deciding about the hardware (HW) components configuration settings. The GREASe provides all possible application bundles and service bundles including a reusable management interface, a Message Sequence Chart (MSC) catalogue, SNMP (Simple Network Management Protocol) and MIB (Management Information Base). Due to the hardware adaptation layer and the operating system (OS) adaptation layer, this software-package is HW- or OS-independent.

How to utilize an embodiment of the GREASe in combination with a DSLAM (Digital Subscriber Line Access Multiplexer) is shown exemplary in Figure 1 and Figure 2. For example, a subscriber A applies for 64Kbit/s VoIP (Voice over IP, Internet Protocol), 20Mbit/s fast internet access and gaming discarding service. To meet this requirement, the rule engine can be integrated in an access product for configuration of the HW-switching components to support the required services. In the example, three applications and service bindings have to be configured - one for VoIP, one for fast internet and one for gaming. The SNMP interface receives a SNMP message from the SNMP agent and calls the Generic Rule Engine to translate these bindings into rules and to configure then the switching HW via the HW adaptation layer.

In order to supply this feature independent of the selected service, the rule engine is a plug and play SW package. According to this software structure, the following interfaces are supported: HW adaptation layer, OS adaptation layer, SNMP interface and external database interface. This solution can be very easily integrated into different HW or SW platforms or upgraded to support certain service level agreement features.

Advantages of the described solution by a Generic Rule Engine are:

- It leads to a clear view on application bundles in combination with different levels of QoS agreements.

- The use of a Generic Rule Engine makes the payment model 'pay based on subscriber's willingness' possible.

- It helps to setup a carrier grade Ethernet.

- For running new Ethernet based access products, only a little adaptation has to be done at the

Generic Rule Engine.
