摘要:
The invention concerns a method of handling a signalling and management communication traffic in a network element, as well as the network element to execute this method. The signalling and management communication traffic is transmitted between network elements of a transmission system in embedded communication channels by means of a HDLC-framed point-to-point protocol. Said network element receives the signalling and management communication traffic on one or more first embedded communication channels via one or more embedded communication channel interfaces. The received signalling and management communication traffic is trans-coded by stripping a data payload (205) from frames (200) according to a HDLC-framed point-to-point protocol and inserting the stripped data payload (305) into Ethernet frames (300). The trans-coded signalling and management communication traffic is routed by means of an Ethernet-based routing unit.

Switching and routing functions may be provided in a data plane of a network switch by having all functions and algorithms needed to handle all related interface, logical and physical, under one interface manager to keep track of bindings between virtual interfaces and logical interfaces, as well as maintain the statuses of ports that belong to the virtual interface and the actual logical ports. When the actual interface goes down, the virtual interface may go down along with it. The bindings may also include definitions. AU of these bindings may be located in a single routing information base (RIB) database, eliminating the need for multiple bindings to be kept in various places. Furthermore, a hardware abstraction layer in the control plane can also then be mirrored in the data plane, eliminating the need for the customer to create a layer performing the same tasks.

Die Erfindung betrifft ein modulares industrielles Automatisierungsgerät mit einem Rückwandbus-System, mehreren an das Rückwandbus-System angeschlossenen Funktionsmodulen, die jeweils einen Kommunikationsnetzadapter, eine Protocol-Funktionseinheit zur Implementierung eines Kommunikationsprotokollstapels und ein mit dem Kommunikationsnetzadapter verknüpftes MAC-Brückenelement umfassen. Außerdem ist ein an das Rückwandbus-System angeschlossenes Router-Modul vorgesehen, das einen Kommunikationsnetzadapter, eine mit dem Kommunikationsnetzadapter verknüpfte Router-Funktionseinheit zur Implementierung eines Router-Kommunikationsprotokollstapels und für jedes Funktionsmodul jeweils ein virtueller Kommunikationsnetzadapter umfaßt. Ein solcher virtueller Kommunikationsnetzadapter verknüpft die Router-Funktionseinheit über das Rückwandbus-System mit dem MAC-Brückenelement des jeweiligen Funktionsmoduls. Nur der Kommunikationsprotokollstapel des Router-Moduls umfaßt Routing-Funktionen. Das Weiterleiten der Nachrichten erfolgt anhand der Ziel-MAC-Adresse.

The invention relates to switch based aggregation system, method and computer program product for providing Quality of Service (QoS) to a layer 2 configured network comprising a connection oriented switching means connected to a Wide Area Network (WAN). The system comprises an Adaptive Quality of Service (AQS) means connected to said switching means. The Adaptive Quality of Service (AQS) means comprises monitoring means for monitoring the total IP data throughput stream and the RTCP reports in the system, filtering means being capable of filtering the total IP data throughput stream and controlling means for controlling said filtering means depending on the monitoring of the total IP data throughput stream and adaptable filter criteria.

Methods and a system and devices for IPv6 datagram transmission in the Ethernet are provided. Wherein, when the network device transmits IPv6 datagram via Ethernet, a sender only adds IPv6 datagram and check field to form a Ethernet frame, then a receiver receiving the Ethernet frame can quickly acquire the datagram. Methods and a system and devices can simplify the packaging and improve the transmission efficiency of data pure load.
