A method performed by a network controller for a mobile transport network. The method includes: obtaining traffic information for a plurality of demands for connectivity from client nodes through the mobile transport network, the traffic information for each demand identifying a client node for the demand, an egress node for the demand and an amount of traffic for the demand; calculating, for each demand, one or more paths from the client node, via an ingress node, to the egress node through the mobile transport network; mapping each path for a demand to a source port in the ingress node for the demand; providing the mapping to the ingress nodes to enable routing of traffic pertaining to the demands via the paths, based on the source port; and providing the source ports to the client nodes for inclusion in traffic pertaining to the demands.

The present disclosure provides a method () in a network node advertising a Binding Segment Identifier, BSID. The method () includes: receiving () a first echo request packet containing a first target Forwarding Equivalence Class, FEC, stack including an FEC associated with the BSID; and transmitting (), in response to a Time To Live, TTL, expiration associated with the first echo request packet, a first echo reply packet to an initiating network node initiating the first echo request packet, the first echo reply packet containing an indicator indicating that the FEC is to be replaced by a set of FECs.

An approach for identifying and managing tasks in an e-mail system. An e-mail task manager, receives an e-mail and creates n-grams based on e-mail data content and metadata content. The e-mail task manager identifies the e-mail as a task e-mail based on analyzing the n-grams to detect a task and a task owner. The e-mail task manager determines task details associated with the task e-mail based on the n-grams and determines a collection of recommended actions based on the task details. The e-mail task manager stores the collection of recommended actions and associated action states in a task history store. The e-mail task manager outputs the collection of recommended actions and the action states associated with the task e-mail based on the task owner and updates the collection of recommend actions and the associated action states based on interactions by the task owner.

In accordance with an embodiment, described herein is a system and method for supporting namespaces in a multitenant application server environment. The application server environment can include a domain with a plurality of partitions. A global namespace or JNDI tree bound to domain-level resources can maintain a collection of partition root nodes, with each partition root node being the root node of a partition JNDI tree. Each node in a partition JNDI tree is made partition-aware by including properties specific to a particular partition. An initial context for a partition can be created for use in dispatching resource lookup requests to the partition, and can be reused by other applications in accessing resources in the partition.

A centrifugal compressor has a casing. In the casingis formed a back-flow channelto return fluid from a downstream position of an impeller full blade leading edgeto an upstream position of the impeller full blade leading edge. The back-flow channelincludes a suction ring grooveand a back-flow ring groove. The suction ring groove opens at the downstream position on the inner faceof the casing, and extends in the circumferential direction. The back-flow ring groove opens at the upstream position on the inner face, and extends in the circumferential direction. Distribution in the circumferential direction of the axial-direction position of the suction ring grooveor a width of the suction ring grooveis asymmetric with reference to the rotation axis.

A centrifugal compressor includes: a volute casing including a first casing and a second casing that are mutually coupled, the first casing including a volute chamber therein and the second casing including an impeller installation space therein; an impeller provided in the impeller installation space so as to be rotatable around a rotation axis; and a vaneless diffuser that has an inlet that communicates with an inside of the second casing and has an outlet that communicates with an inside of the first casing. The vaneless diffuser has a width having a non-axisymmetric distribution in the circumferential direction.
