  • Patent number: 10846121
    Abstract: A method and system to improve datacenter security by configuring a security layer as a set of nano-services that are executed to service a single tenant of the datacenter such that the nano-service protects the single tenant from other entities in the datacenter and the nano-service being compromised does not compromise the security of other tenants of the datacenter. The method includes receiving a request to instantiate a virtual resource for a tenant, generating a nano-service to implement at least one security layer function for the virtual resource, and connecting the nano-service to the virtual resource and a virtual bridge in the datacenter to enable communication between the virtual resource (vR) and a network of the datacenter with the security layer function processing traffic between the virtual resource and the virtual bridge. The nano-service can be immutable once it begins execution. The security layer function can be an L2 or L3 function.

  • Patent number: 10419530
    Abstract: A method implemented by a computing device to optimize resource usage of service function chains (SFCs) in a network using machine learning. The method includes obtaining, from an autoscale machine learning (ML) system associated with a virtual network function (vNF), a suggested adjustment to an amount of resources provisioned for the vNF. The autoscale ML system is trained online using machine learning to predict an amount of resources to be utilized by the vNF. The autoscale ML system is configured to receive as input an amount of resources currently utilized by the vNF and an amount of resources currently available to the vNF, determine using machine learning the suggested adjustment to the amount of resources provisioned for the vNF based on the input, and output the suggested adjustment. The method further includes providing the suggested adjustment to a resource re-allocator component.

  • Patent number: 10356182
    Abstract: A method and a computing device are provided for improving datacenter operation. The datacenter operation is improved by establishing differentiated communication protocol stack support as a set of nano-services. The nano-services are executed to service connections on a per application or server basis for the datacenter to reduce overhead caused by virtual machines or containers utilizing separate communication protocol stacks. The method includes receiving a request to for a server via a known network access type, from a known application type, by a known user, or a known policy, determining whether the request can be serviced by an existing nano-service for the server, and establishing a new nano-service with a differentiated communication protocol stack instance for the server, in response to the request not being serviced by the existing nano-service.

  • Patent number: 10009261
    Abstract: Methods implemented in an electronic device are disclosed for checkpoint and rollback recovery in a SDN system. The method utilizes message identifiers to indicate an order of consistent states of forwarding tables of a plurality of network elements of the SDN system. The SDN controller of the SDN system receives a request to recover the network to a previous state, and identifies a consistent state of forwarding table for each of the plurality of network elements utilizing the message identifiers associated the consistent states, where the identified consistent states represent the previous state of the network without the identified consistent states being captured at the same time at the plurality of network elements. The SDN controller indicates the identified consistent state for each of the plurality of the network elements to a corresponding network element, where the corresponding network element makes its forwarding table consistent with the identified consistent state.
