Multi-tenant network provisioning is disclosed. An example method of multi-tenant network provisioning includes setting at least one rate limiter on output ports of a node in the network on a tenant-by-tenant basis. The method also includes enforcing communication rates over shared edge links based on the rate limiter.

A configurable Clos network includes leafs and spines and a switch fabric that connects the leafs and the spines. The switch fabric couples each leaf port of each leaf to at least one spine port of each spine.

Embodiments herein relate to addition or modification to a forwarding table based on an address. A first packet having a source address and a location value may be received. The source address includes a source of the first packet and the location value indicates at least part of a route along a network to the source address. The forwarding table is not modified or no new entry is added to the forwarding table, if the forwarding table does not include the source address.

An optical interconnect (200) includes: a reflective body (230) having a first reflective surface (235) and a second reflective surface (240) opposite the first reflective surface (235); a first optical waveguide (205) that directs a first optical signal received from a first communicating device (105) to the first reflective surface (235); a second optical waveguide (210) that directs the first optical signal from the first reflective surface (235) of the reflective body (230) to a second communicating device (110); a third optical waveguide (215) that directs a second optical signal received from the second communicating device (110) to the second reflective surface (240) of the reflective body (230); and a fourth optical waveguide (220) that directs the second optical signal from the second reflective surface (240) of the reflective body (230) to the first communicating device (105).

摘要:
Remote memory can be used for a number idle pages located on a virtual machine. A number of idle pages can be sent to the remote memory according to a placement policy, where the placement policy can include a number of weighting factors. A hypervisor on a computing device can record a local size and a remote page fault frequency of the number of virtual machines. The hypervisor can scan local memory to determine the number of idle pages and a number of idle virtual machines. The number of idle pages, including a page map and a remote address destination for each idle page, can be sent to the remote memory by the hypervisor. The number of virtual machines can be analyzed to determine a per-virtual machine local memory allocation.
摘要:
A first virtual machine is implemented on one or more computing devices to generate input/output (I/O) requests to a hardware device. A second virtual machine is also implemented on the computing devices. A mechanism is to switch between a direct mode and an indirect mode without switching between a first context and a second context of the hardware device. In the direct mode, the I/O requests generated by the first virtual machine are to be sent to the hardware device without being redirected to the second virtual machine. In the indirect mode, the I/O requests generated by the first virtual machine are to be redirected to the second virtual machine for processing. The second virtual machine is to, after processing the I/O requests redirected to the second virtual machine, send the I/O requests to the hardware device.
摘要:
According to an example, a method for bandwidth guarantee and work conservation includes determining virtual machine (VM) bandwidth guarantees assigned to VMs in a network including a source VM that communicates with destination VMs. The method further includes assigning minimum bandwidth guarantees to communications between the source VM with the destination VMs by dividing a VM bandwidth guarantee assigned to the source VM between the destination VMs based on active VM-to-VM communications between the source VM and the destination VMs. The method also includes allocating, by a processor, spare bandwidth capacity in the network to a communication between the source VM and a destination VM based on the assigned minimum bandwidth guarantees.
摘要:
A networking packet is to be sent from a first virtual machine of a computing device to a second virtual machine of the computing device. A hardware network interface controller (NIC) of the computing device is to determine whether the networking packet is to be routed from the first virtual machine to the second virtual machine in accordance with a first approach or a second approach, based upon one or more considerations regarding a state of the computing device. The hardware NIC is then to control routing of the networking packet in accordance with the first approach or the second approach.
摘要:
A memory has a page to store code executable by a processor. A management component is to inject the code into a virtual machine. The management component is to indicate within a memory table for the virtual machine that the page of the memory has an injected code type.
