Embodiment Construction

[0018] In the following description, for purposes of explanation rather than limitation, specific details are set forth (eg, specific device and system configurations and specific methods, steps and functions) in order to provide a thorough understanding of the techniques presented herein. It will be appreciated by those skilled in the art that the technology may also be practiced in other embodiments that depart from these specific details.

[0019] Those skilled in the art will also recognize that the methods, steps, and functions described herein may be implemented using separate hardware circuits, using software functions in conjunction with a programmed microprocessor or general-purpose computer, using one or more application-specific integrated circuits (ASICs), one or more Multiple Data Signal Processors (DSPs) and / or one or more Field Programmable Gate Arrays (FPGAs). It will also be appreciated that the techniques disclosed herein can be implemented in a processor and...

Abstract

A technique for triggering an association between a Media Access Control (MAC) address and a switch port is provided. The association allows forwarding data frames including the MAC address as destination MAC address via the associated switch port. As to a method aspect of the technique, a data frame originating from a node (18) is received. The data frame includes a MAC address of the originating note (18) as source MAC address. The data frame is stored including the MAC address. The data frame is successfully sent towards a first switch port (112). In response to a failure of a first link (122) towards the first switch port (112), the stored data frame is resent towards a seconds switch port (114; 116) that is different from the first switch port (112) for triggering the association between the second switch port (114; 16) and the MAC address of the originating node (18).

Description

technical field [0001] The present disclosure generally relates to techniques for providing web services. In particular and without limitation, the present disclosure relates to devices and methods for providing network services with a specific quality of service. Background technique [0002] To achieve high availability of network services, alternate links between network components provide alternate paths. For example, providing network access to multiple hosts using a protocol at any of layers 3-7 of the OSI model is traditionally implemented using protection mechanisms at layer 2 of the Open Systems Interconnection (OSI) model, so The above protection mechanism provides an alternative link or an alternate path. This protection mechanism includes Ethernet Ring Protection (ERP), Link Aggregation (LAG), Spanning Tree Protocol (STP), Multi-Protocol Label Switching Transport Profile (MPLS-TP), etc. [0003] When a link failure is detected in the network, data traffic that...
