PCIe devices installed in host computers communicating with service nodes can provide virtualized and high availability PCIe functions to host computer workloads. The PCIe device can receive a PCIe TLP encapsulated in a PCIe DLLP via a PCIe bus. The TLP includes a TLP address value, a TLP requester identifier, and a TLP type. The PCIe device can terminate the PCIe transaction by sending a DLLP ACK message to the host computer in response to receiving the TLP. The TLP packet can be used to create a workload request capsule that includes a request type indicator, an address offset, and a workload request identifier. A workload request packet that includes the workload request capsule can be sent to a virtualized service endpoint. The service node, implementing the virtualized service endpoint, receives a workload response packet that includes the workload request identifier and a workload response payload.

Presented herein are techniques performed in a network comprising a plurality of network nodes each configured to apply one or more service functions to traffic that passes the respective network nodes in a service path. At a network node, an indication is received of a failure or degradation of one or more service functions or applications applied to traffic at the network node. Data descriptive of the failure or degradation is generated. A previous service hop network node at which a service function or application was applied to traffic in the service path is determined. The data descriptive of the failure or degradation is communicated to the previous service hop network node.

In general, techniques are described for network connectivity for non-colocated customers of a cloud exchange. A programmable network platform for the cloud exchange comprises processing circuitry configured to: configure a virtual network device in the data center to run a network service for a customer; receive, from the customer, a request for a remote port and network information for a network service provider connectivity service for the customer; assign, in response to receiving the request for the remote port, a remote port of the cloud exchange to the customer; and configure, in response to receiving the request for the remote port using the network information, the cloud exchange to connect the network service provider connectivity service to the virtual network device via the remote port of the cloud exchange.

Methods, computer program products, and systems are presented. The methods include, for instance: providing a distributed virtual gateway for Network Virtualization over Layer 3 (NVO3) network. A gateway stack having three or more nodes is implemented as a distributed virtual gateway, providing Layer 2 or Layer 3 gateway services in a fail-safe manner. Nodes of the gateway stack are configured to autonomously process and forward inbound NVO3 data packets with known destination addresses without engaging a master of the gateway stack.

An intelligent wireless broadband network and content delivery management within a network includes at least one datacenter, at least one network tower and a plurality of smart nodes may be provided. Each of the plurality of smart nodes may be deployed as a micro point of presence (micro POP) at the at least one datacenter the at least one tower and at each of a plurality of hub-homes within the network. An artificial intelligence (AI) capable compute unit may be configured to provide customization of the plurality of smart nodes based on usage pattern of the plurality of homes at a neighborhood level, and thereby facilitating a dynamic edge network distribution solution for better Internet experience to the end-users.

A novel design of a gateway that handles traffic in and out of a network by using a datapath pipeline is provided. The datapath pipeline includes multiple stages for performing various data-plane packet-processing operations at the edge of the network. The processing stages include centralized routing stages and distributed routing stages. The processing stages can include service-providing stages such as NAT and firewall. The gateway caches the result previous packet operations and reapplies the result to subsequent packets that meet certain criteria. For packets that do not have applicable or valid result from previous packet processing operations, the gateway datapath daemon executes the pipelined packet processing stages and records a set of data from each stage of the pipeline and synthesizes those data into a cache entry for subsequent packets.

Systems and methods described herein support a usage calculation process in a cloud infrastructure environment. The usage calculation process can be used to determine whether a requested transaction that targets a compartment within a tree-structure of compartments violates any compartment quota or limit within parent compartments within the tree-structure.

The present invention provides for fabricating virtual networks and allocating request-notifications therein for providing support-services securely and efficiently. In operation, a virtual network is fabricated based on network-registration requests received from plurality of computing devices. Further, a primary data structure representative of registered computing devices categorized into devices offering services and requiring services is generated based on information embedded in network-registration requests. Furthermore, a secondary data structure is generated by sub-categorising categorised computing devices based on information embedded in network-registration requests. Yet further, request-notifications for completing incoming support-requests from registered computing devices requiring services are generated. Subsequently, request-notifications are allocated based on evaluation of one or more computing devices offering services out of plurality of computing devices based on data mapping using primary data structure, secondary data structure, and predefined attributes. Finally, support-information sharing and tracking of request-notifications are enabled based on acceptance of request-notification by evaluated computing devices.

A packet processing method includes receiving, by a forwarding plane device, a first packet transmitted by a user, where an identity of the user is comprised in the first packet, and a forwarding table is comprised in the forwarding plane device, determining, by the forwarding plane device, an identity of a service according to a corresponding relationship between the identity of the user and the identity of the service as well as the identity of the user in the first packet, generating, by the forwarding plane device, a second packet by encapsulating the first packet with the identity of the service, and transmitting the second packet to a network device to enable the network device to manage the service according to the identity of the service in the second packet.
