20130182706 | REQUESTING MULTICAST MEMBERSHIP INFORMATION IN A DISTRIBUTED SWITCH IN RESPONSE TO A MISS EVENT - Apparatuses and methods to request multicast membership information in a distributed switch are provided. A particular method may include requesting multicast membership information of a group identified by a multicast destination address in a distributed switch. The distributed switch may include a plurality of distributed switch elements with a plurality of switch forwarding units. The method may generate a miss event indicating that the multicast destination address is unregistered in a switch forwarding unit of a distributed switch element and there is a need for the multicast membership information. The method may also request the multicast membership information of the multicast destination address in response to the miss event. The method may further initiate a query for the multicast membership information of the multicast destination address in response to the request. | 07-18-2013 |
20130182707 | MANAGING A GLOBAL FORWARDING TABLE IN A DISTRIBUTED SWITCH - Apparatuses and methods to manage a global forwarding table in a distributed switch are provided. A particular method may include managing a global forwarding table in a distributed switch. The distributed switch may include a plurality of switch forwarding units. The method may start a timer for an entry in the global forwarding table, and the entry may include a multicast destination address and corresponding multicast membership information. The method may also, in response to expiration of the timer of the entry, check at least one hit status to determine whether at least one switch forwarding unit of the plurality of switch forwarding units has forwarded multicast data to the corresponding multicast membership information of the multicast destination address of the entry. The method may further determine whether the entry is a cast-out candidate based on the hit status. | 07-18-2013 |
20140079061 | FACILITATING INSERTION OF DEVICE MAC ADDRESSES INTO A FORWARDING DATABASE - Techniques are disclosed for hash-based routing table management in a distributed network switch having multiple switch modules. Upon determining that an attempt to insert a first routing entry into a first hash table of the routing table has failed, a second routing entry, which exists in the first hash table, is attempted to be moved to a second hash table of the routing table. If the move attempt is successful, then the first routing entry is added to the location previously occupied by the second routing entry. If the move attempt is unsuccessful, then a third routing entry, which exists in the first hash table, is attempted to be moved. | 03-20-2014 |

20140146823 | MANAGEMENT OF ROUTING TABLES SHARED BY LOGICAL SWITCH PARTITIONS IN A DISTRIBUTED NETWORK SWITCH - Techniques are provided for managing a routing table in a distributed network switch. The distributed network switch is divided into logical switch partitions, or logical networks, that may share a routing table. The shared routing table is configured with counters and thresholds to control utilization of the routing table on a per-logical network basis. When counters exceed certain threshold, the routing table is modified to reduce routing entries within the routing table or pause insertion of new routing entries. | 05-29-2014 |

20130223204 | Communication Device for a Redundantly Operable Industrial Communication Network and Method for Operating the Communication Device - A communication device for a redundantly operable industrial communication network comprises at least one first and one second transmitting and receiving unit each having an interface for a network connection of the industrial communication network. A signal processing unit is connected to the first and second transmitting and receiving units. A singly linked network node is connected to the signal processing unit via a coupling element. The signal processing unit is connected to the coupling element via a first and second interface. In this case, the first interface is provided exclusively for communicating data packets received by the first receiving unit, while the second interface is provided exclusively for communicating data packets received by the second receiving unit. | 08-29-2013 |
20130286820 | Communication Device For An Industrial Communication Network Which Can Be Operated In A Redundant Manner And Method For Operating A Communication Device - A communication device for an industrial communication network which can be operated in a redundant manner comprises a first and a second transmitting and receiving unit that transmit data packets in a bumpy or bumpless manner inside the industrial communication network and are selectively changeable over to a bumpy or bumpless transmission mode. An evaluation unit is connected to the first and/or second transmitting and receiving unit(s) and detects data packets to be transmitted in the bumpy or bumpless manner inside the industrial communication network. Redundancy handling and filter units for received redundant data packets are deactivated when a data packet to be transmitted in the bumpy manner is detected. A memory unit is assigned to the first and/or second transmitting and receiving unit(s) and buffers at least one data packet to be transmitted in the bumpy manner during a predefined period of time in the bumpy transmission mode. | 10-31-2013 |
20140086136 | Redundantly Operable Industrial Communication System and Method for Operation Thereof - A redundantly operated industrial communication system includes communication devices that are redundantly linked to an industrial communication network and includes network infrastructure devices associated with the industrial communication network, wherein message transmission occurs wirelessly at least in sections. The industrial communication network contains a plurality of buffer memory units for message elements that are received at a network node by wire and message elements that are to be sent by the network node wirelessly. When a maximum buffer size is exceeded, an oldest message element situated in a respective buffer memory unit is erased. Until the maximum buffer size is exceeded, the oldest message element is selected as the next message element to be sent wirelessly. | 03-27-2014 |
20150049639 | Communication Device and Method for Redundant Message Transmission in an Industrial Communication Network - For redundant message transmission in an industrial communication network having an arbitrarily meshed network topology, mutually independent paths are ascertained for a communication link that is redundant at least in sections between two network nodes within the industrial communication network, where the mutually independent paths comprise separate network nodes of a single communication network, and messages with duplicate identifiers are interchanged between transmission and reception units of communication devices of the industrial communication network in accordance with forwarding rules that correspond to the ascertained paths. | 02-19-2015 |
