Abstract:
Failover of network nodes is disclosed. A first node joins a multicast group (102). The joining is performed by performing one of three actions (104). First, a failover address is associated with the first node, and the first node effectively joins the group having this address as a multicast address. Second, a multicast address is associated with the first node. Third, a switch' s multicast port is mapped to a first node port. Upon failure of the first node (106), one of three actions is performed. If the joining associated the failover address, this is associated with a second node, and the second node effectively joins the group (114). If the joining associated the multicast address, the second node joins the group and this address is associated with the second node (110). If the joining mapped the switch's multicast port, this port is remapped to a second node port (112).
Abstract:
A network endpoint system and related method and computer program product for use in a network to support enhanced end-to-end QoS in the network. The network endpoint system is adapted to receive network data of varying priority on behalf of a data consumer operating at the application layer of a network protocol stack implemented by the network endpoint system. The network endpoint system includes a network interface controller adapted to receive network frames containing the network data, plural network data handling channels each having an associated priority, and priority processing logic adapted to transfer the network data from the network interface controller to the plural data handling channels on a prioritized basis according to the network data priority. Also disclosed are a network interface controller and a network node to support enhanced end-to-end QoS in a network.
Abstract:
Es werden ein transparenter, leistungssteigernder Proxy, ein Verfahren zum Betreiben eines transparenten, leistungssteigernden Proxy zwischen einer Quelleneinheit und einer Zieleinheit und ein entsprechendes Computerprogrammprodukt bereitgestellt. Das Verfahren beinhaltet das Beibehalten, ohne Umsetzung, von Paket-Kopfbereichinformationen eines Kopfbereichs für ein von der Quelleneinheit empfangenes Paket, das an die Zieleinheit weitergeleitet werden soll. Das Verfahren beinhaltet des Weiteren das Beibehalten der Verbindungssemantik des Übertragungssteuerungsprotokolls während einer Verbindungsaufbauphase des Übertragungssteuerungsprotokolls für das Paket. Das Verfahren beinhaltet während einer Datenübertragungsphase des Übertragungssteuerungsprotokolls für das Paket auch das Ausführen eines Übertragungssteuerungsprotokolls, indem ein Ausgeben als Quelleneinheit gegenüber der Zieleinheit und ein Ausgeben als Zieleinheit gegenüber der Quelleneinheit erfolgt, um das Paket mit den beibehaltenen Paket-Kopfbereichinformationen an die Zieleinheit zu übertragen.

Abstract:
The failover of nodes within networks, using a multicast address or a multicast port, is disclosed. A first node of a network joins a multicast group having a multicast address, which is assigned to the first node. Communication to the first node is achieved via communication to the multicast address, and/or through a multicast port on a switch of the network mapping to a port on the first node. When the first node fails, one of two actions occurs. First, a second node of the network may join the multicast group, such that the multicast address is assigned to the second node, and the second node handles communication to the multicast address. Second, the multicast port on the switch may be remapped to a port on the second node, so that communication to the multicast address is directed to the port on the second node.
