Abstract:
Calculating routing after switching occurs from a primary main control board to a standby main control board in a Fiber Channel (FC) switch includes receiving neighbor Link State Records (LSRs) sent by the primary main control board and backing up the neighbor LSRs on the standby main control board. The standby main control board is triggered to be promoted to the primary main control board, and an adjacency relationship is established with neighbors according to the backed up neighbor LSRs. LSRs of the switch are generated based on available ports on the switch and the neighbors, and a message is sent for maintaining the adjacency relationship to the neighbors with which the adjacency relationship has been established. Routing is calculated based on the neighbor LSRs and the LSRs of the switch.
Abstract:
A control method of virtual link discovery and a system for Fibre Channel over Ethernet (FCoE) protocol allocates some Ethernet Nodes (ENodes) and FCoE Forwarders (FCFs) to different virtual networks during networking, and provides a Virtual Node (VN) port of each ENode and a Virtual Fibre Channel (VFC) port of each FCF with a Virtual Network Identification (VN ID) of a virtual network to which they belong. In this way, a VN port of an ENode may establish a virtual link with a VFC port that belongs to the same virtual network in preference, so that some ENodes are made to access FCFs that belong to the to same virtual networks as the ENodes.
Abstract:
A process for preparing polypropylene compositions having high impact strength at low temperatures is disclosed in which the reaction is catalyzed by Ziegler-Natta/metallocene hybrid catalysts by the in-situ polymerization of one or more olefins of the formula CH2═CHR, in which R is hydrogen or an alkyl, cycloalkyl or aryl group having from 1 to 10 carbon atoms, and more specifically comprises preparing an olefin polymer by Ziegler-Natta catalyst components of the titanium or vanadium/metallocene hybrid catalysts while the metallocene components are inactivated beforehand by catalyst inactivators; and polymerizing one or more olefins in the presence of the above olefin polymer, followed by a reactivation of the metallocene components.
Abstract:
The present disclosure provides a method for backing up a link state advertisement (LSA) for use in a distributed device comprising a main control board and an interface board. The main control board comprises a primary board and a standby board. The method comprises: receiving by the standby board LSA related information sent by the primary board; and generating by the standby board an LSA according to the LSA related information.
