Abstract: A method in a network element that includes multiple interfaces for connecting to a communication network includes receiving from the communication network via an ingress interface a flow including a sequence of packets, and routing the packets to a destination of the flow via a first egress interface. A permission indication for re-routing the flow is received in the ingress interface. In response to receiving the permission indication, subsequent packets of the flow are re-routed via a second egress interface that is different from the first egress interface. Further re-routing of the flow is refrained from, until receiving another permission indication.

Abstract: A method for data transfer includes receiving in an input/output (I/O) operation a first segment of data to be written to a specified virtual address in a host memory. Upon receiving the first segment of the data, it is detected that a first page that contains the specified virtual address is swapped out of the host memory. At least one second page of the host memory is identified, to which a second segment of the data is expected to be written. Responsively to detecting that the first page is swapped out and to identifying the at least one second page, at least the first and second pages are swapped into the host memory. After swapping at least the first and second pages into the host memory, the data are written to the first and second pages.

Abstract: In a data network congestion control in a virtualized environment is enforced in packet flows to and from virtual machines in a host. A hypervisor and network interface hardware in the host are trusted components. Enforcement comprises estimating congestion states in the data network attributable to respective packet flows, recognizing a new packet that belongs to one of the data packet flows, and using one or more of the trusted components and to make a determination based on the congestion states that the new packet belongs to a congestion-producing packet flow. A congestion-control policy is applied by one or more of the trusted components to the new packet responsively to the determination.
