Embodiments are generally directed apparatuses, methods, techniques and so forth to select two or more processing units of the plurality of processing units to process a workload, and configure a circuit switch to link the two or more processing units to process the workload, the two or more processing units each linked to each other via paths of communication and the circuit switch.

An information processing apparatus includes, in an aspect, a communication port, a reading unit, a determination unit, a collecting unit, and a sending unit. When a communication cable is connected to the communication port, the reading unit reads a failure condition table and a collection item table from a storage unit provided in a communication cable. The determination unit determines whether the state of communication via the communication cable connected to the communication port satisfies the condition in the failure condition table. When the determination unit determines that the state of the communication via the communication cable connected to the communication port satisfies the condition, the collecting unit collects the information corresponding to the item in the collection item table. The sending unit sends the information collected by the collecting unit to a predetermined device.

In one embodiment, an apparatus includes a switch core that has a multi-stage switch fabric. A first set of peripheral processing devices coupled to the multi-stage switch fabric by a set of connections that have a protocol. Each peripheral processing device from the first set of peripheral processing devices is a storage node that has virtualized resources. The virtualized resources of the first set of peripheral processing devices collectively define a virtual storage resource interconnected by the switch core. A second set of peripheral processing devices coupled to the multi-stage switch fabric by a set of connections that have the protocol. Each peripheral processing device from the first set of peripheral processing devices is a compute node that has virtualized resources. The virtualized resources of the second set of peripheral processing devices collectively define a virtual compute resource interconnected by the switch core.

In one aspect, a computerized system useful for implementing a virtual private network (VPN) including an edge device that automatically establishes an Internet Protocol Security (IPsec) tunnel alongside an unsecure Multipath Protocol (MP) tunnel with a gateway device in preparation for a transmission of a secure traffic communication. The edge device has a list of local subnets. The edge device sends the list of local subnets to the gateway during an initial MP tunnel establishment handshake message exchange between the edge device and the gateway device. Each subnet includes an indication of whether the subnet is reachable over the VPN. A gateway device that automatically establishes the IPsec tunnel alongside the unsecure MP tunnel with the edge device. An enterprise datacenter server that comprises an orchestrator module that receives a toggle the VPN command and enables the VPN on the orchestrator. The orchestrator informs the edge device the list of subnets is accessible over the VPN causing the edge device to update the gateway device with a new list of subnets of the edge device that accessible over the VPN.

Some embodiments provide a method for configuring a gateway machine in a datacenter. The method receives a definition of a logical network for implementation in the datacenter. The logical network includes at least one logical switch to which logical network endpoints attach and a logical router for handling data traffic between the logical network endpoints in the datacenter and an external network. The method receives configuration data attaching a third-party service to at least one interface of the logical router via an additional logical switch designated for service attachments. The third-party service is for performing non-forwarding processing on the data traffic between the logical network endpoints and the external network. The method configures the gateway machine in the datacenter to implement the logical router and redirect at least a subset of the data traffic between the logical network endpoints and the external network to the attached third-party service.

A first ingress interface on a switch receives a first control packet for establishing a Transmission Control Protocol (TCP) session and selects a first engine running on a first line card in the switch. A second ingress interface receives a second control packet and selects the same first engine. Data associated with the TCP session received by the first or second ingress interface subsequent to establishing the TCP session is to be forwarded to the first engine. The first ingress interface receives a third control packet and sends, to the selected first engine, a notification indicating the TCP session which is to be tracked. The first or second ingress interface receives a fourth packet with a payload associated with the TCP session and forwards, to the selected first engine, a copy of the fourth packet, thereby facilitating a plurality of engine instances to support application identification.

Techniques for managing operation in cloud computing systems are disclosed herein. In one embodiment, a method can include receiving data representing a guaranteed value of a performance metric of a cloud service and an error budget and deriving a switching threshold based on a combination of the value of the performance metric and the error budget. The method also includes determining a current value of the performance metric of the cloud service and causing the cloud computing system to selectively switch between operational modes for providing the cloud service based on a comparison between the determined current value of the performance metric and the switching threshold.
