Definitions

  • Embodiments described herein generally relate to network monitoring and tuning and in particular, to a system and method for implementing reputation management and intent-based security mechanisms.
  • Edge computing at a general level, refers to the transition of compute and storage resources closer to endpoint devices (e.g., consumer computing devices, user equipment, etc.) in order to optimize total cost of ownership, reduce application latency, improve service capabilities, and improve compliance with security or data privacy requirements.
  • Edge computing may, in some scenarios, provide a cloud-like distributed service that offers orchestration and management for applications among many types of storage and compute resources.
  • some implementations of edge computing have been referred to as the “edge cloud” or the “fog”, as powerful computing resources previously available only in large remote data centers are moved closer to endpoints and made available for use by consumers at the “edge” of the network.
  • MEC multi-access edge computing
  • ISG industry specification group
  • Edge computing, MEC, and related technologies attempt to provide reduced latency, increased responsiveness, and more available computing power than offered in traditional cloud network services and wide area network connections.
  • the integration of mobility and dynamically launched services to some mobile use and device processing use cases has led to limitations and concerns with orchestration, functional coordination, and resource management, especially in complex mobility settings where many participants (devices, hosts, tenants, service providers, operators) are involved.
  • IoT Internet of Things
  • IoT devices are physical or virtualized objects that may communicate on a network, and may include sensors, actuators, and other input/output components, which may be used to collect data or perform actions in a real-world environment.
  • IoT devices may include low-powered endpoint devices that are embedded or attached to everyday things, such as buildings, vehicles, packages, etc., to provide an additional level of artificial sensory perception of those things.
  • IoT devices have become more popular and thus applications using these devices have proliferated.

  • FIG. 20 is a flowchart illustrating a method for reputation management and intent-based security mechanisms, according to an embodiment.
  • QoS management is mostly built around requesting the correct quantity of resources (e.g., number of virtual central processing units (vCPUs)), or hardware features to support the workloads at the cloud and edge.
  • vCPUs virtual central processing units
  • Performing orchestration this way has several issues. It creates unwanted vendor-lock in, as specific feature sets specified by one vendor may not be available by equipment provided by another vendor. Further, experience shows that incorrect information is declared in the QoS request and hence leads to sub-optimal performance Finally, these declarations have context that are not included in the QoS management scheme. For instance, the type of platform the application is running on (e.g., Xeon type core vs Atom-based core processors) may affect the provisioning decisions to satisfy a certain QoS request.
  • the type of platform the application is running on e.g., Xeon type core vs Atom-based core processors
  • a service level agreement is an agreement between a service provider and a client.
  • SLAs are contracts between third parties that outline service targets or other business objectives. SLAs may outline penalties for parties who fail to satisfy a target. For example, a partial refund of fees may be enforced when a service is unavailable for more than some threshold percentage over a 90 day period.
  • Service level objectives provide precise numerical targets for various system capabilities. Typical SLOs are oriented around service availability or uptime, service latency, service bandwidth provisioning, etc. SLOs are often expressed as percentages, such as requiring “99.9% uptime over a 30-day period,” or “Response time of less than 100 ms on at least 95% of the requests received.”
  • KPIs Key performance indicators
  • KPI metrics are quantifiable measures of performance over time for a specific objective.
  • KPI metrics are collected to measure SLO policies.
  • Example KPIs include, but are not limited to a number of service errors, downtime, cache misses, frames per second (FPS), latency, instructions per cycle (IPC), security faults, failed logins, etc.
  • KPIs may be derived values (e.g., average latency over a moving 30 second window). KPIs may also be based on comparisons (e.g., percent different from historical average).
  • Service quality objectives may be captured as statistical and deterministic specifications that form a layered, top-down structure, but not constrained to be in a tree or DAG pattern.
  • a meta-language may be used to express key performance indicators (KPIs) and how they are combined to evaluate an overall quality of service (QoS) or Service Level Objective (SLO).
  • KPIs key performance indicators
  • QoS overall quality of service
  • SLO Service Level Objective
  • Various ranges, comparisons, thresholds, constraints, or the like, on the KPIs may be expressed using a meta-language.
  • Most real-world software solutions have to satisfy many intricate demands for performance, scale, accuracy and availability, and these demands are not necessarily fixed for all time or for all situations.
  • a meta-language may be used that expresses the dynamic requirements that need to be met by schedulers of resources.
  • a meta-program written in such a meta-language may introduce variables that, for example, reflect various calibrations that are performed on the behaviors of programs, runtimes, operating systems, infrastructural services, networking gear, and so on. These variables are then woven into higher level variables and results of the meta-programs, and in turn drive corrective, reactive, alertive, and other actions from meta-programs.
  • the structuring is layered so that meta-programs are designed for abstraction and reduction of detail and for convergence to the specified objectives at higher levels.
  • An open architecture is provided so that the layering of policies, heuristics, etc., is not confined by rules of logic alone, but permits the ability to plug-in data-programmed intelligences such as neural networks, support vector machines (SVMs), decision trees, etc.
  • the overall goal is to redirect a portion of computing to such meta-programs and avoid making a strict division between the computations that are part of an application's structure and the computations that are designed to meet a service quality objective during the execution of the application.
  • the ordinary distinction between a control/administrative plane like Kubernetes and a containerized application under which it runs is blurred, and information about the intent and the performance to that intent is allowed to flow bidirectionally at different layers of depth.
  • auto-corrective and auto-indicative capabilities can be co-engineered between the flows in service-objectives and service-quality-objectives.
  • a benefit is that software begins to achieve self-adaptive or co-adaptive accommodation with the environments in which it is activated.
  • SLA Service Level Agreements
  • Statistical admission control policies that attempt to maximize Service Level Agreements (SLA) satisfaction are available and are related to jitter-sensitive network systems.
  • SLA Service Level Agreements
  • the complexity of scheduling resources continues to increase.
  • Very large data centers can provision significant amounts of capacity to perform reactive load-balancing and can defer admission denials to all but the most extreme bursts of demand, but smaller, and less elastic providers of infrastructure have to make tough calls even under statistical policies because when a cutoff is for an outlier tail latency.

  • the systems and methods described herein implement SLAs that are both nested and graduated and are thus burst-accommodative.
  • a token-bucket model with a single queue at a rate limited server a statistical projection for the newest arrival has a mean response time that is proportional to the queue length seen by the new arrival.
  • a na ⁇ ve policy would be to reject the new arrival if this projected response time violates a tail latency constraint; a slightly less na ⁇ ve policy would be to reject the new arrival probabilistically, depending on the queue length and the number of violations that have already occurred.
  • the baseline single queue, single rate server is split into a two-level policy in which the newest arrival is placed in the second queue where it is guaranteed a lower service rate but permitted a more relaxed tail latency.
  • the second queue may have a combination SLO with a P95 latency of 10 ms and a P99 latency of 20 ms. Because extreme bursts are rare, the fractional capacity devoted to the second queue need not be high, because its average queue length is small. In a data center, the movement to a second queue is effectively reassigning the marginal request (the one that is likely to violate a stringent latency bound), to a less utilized but less resourced overflow cluster with correspondingly more relaxed SLO.
  • This scheme can be generalized so that as the second queue approaches its saturation for response time, a third queue with even more liberal SLO absorbs the overflow.
  • a compound nested SLOs within an SLA can be crafted that is adaptive to bursts.
  • the provider can negotiate a similarly graduated cost model in which the savings from not having to provision a lot of peak capacity to meet an inelastic SLA are passed back to customers who accept a nested SLA.
  • the systems and methods described here introduce SLAs that are both nested and graduated. Instead of relying on classic thresholding, and instead of having hard set “single” clause rules to check, a nested sub-clause of the SLA can be evaluated in combination with other sub-clauses to evaluate the overall SLA. This allows more complex rules. Also, “parsing” of the sub-clauses allows results of each clause to create sharing of unused resources. This approach allows more flexibility in the SLA rules and better use of cluster resources. The flexibility can be introduced as an “intent” not a resource specification, which then is mapped to nested/graduated SLA rules which are then monitored and enforced.
  • the systems and methods described herein provide a new way to achieve orchestration, moving from a current model to an objective driven approach, in which the customer expresses only the intent (e.g., latency, throughput, and reliability properties) and the orchestration stack itself sets up the platform to achieve that intent.

  • Compute, memory, and storage are scarce resources, and generally decrease depending on the Edge location (e.g., fewer processing resources being available at consumer endpoint devices, than at a base station, than at a central office).
  • the closer that the Edge location is to the endpoint (e.g., user equipment (UE)) the more that space and power is often constrained.
  • Edge computing attempts to reduce the amount of resources needed for network services, through the distribution of more resources which are located closer both geographically and in network access time. In this manner, Edge computing attempts to bring the compute resources to the workload data where appropriate, or, bring the workload data to the compute resources.
  • Edge cloud architecture that covers multiple potential deployments and addresses restrictions that some network operators or service providers may have in their own infrastructures. These include, variation of configurations based on the Edge location (because edges at a base station level, for instance, may have more constrained performance and capabilities in a multi-tenant scenario); configurations based on the type of compute, memory, storage, fabric, acceleration, or like resources available to Edge locations, tiers of locations, or groups of locations; the service, security, and management and orchestration capabilities; and related objectives to achieve usability and performance of end services. These deployments may accomplish processing in network layers that may be considered as “near Edge”, “close Edge”, “local Edge”, “middle Edge”, or “far Edge” layers, depending on latency, distance, and timing characteristics.
  • Edge computing is a developing paradigm where computing is performed at or closer to the “Edge” of a network, typically through the use of a compute platform (e.g., x86 or ARM compute hardware architecture) implemented at base stations, gateways, network routers, or other devices which are much closer to endpoint devices producing and consuming the data.

  • intents objects
  • Intents are received as higher-level objectives and mapped throughout the orchestration stack to lower-level settings.
  • P50 Latency For example, consider an application requirement that there is certain percentage that something completes in a time window, referred to herein as “P50 Latency.” Other terms may also be used, which may be similar, such as “P50 Target” or “P50 Completions” to indicate that tasks, projects, requests, or the like, need to complete on time at least 50% of the time, or that there is at least a 50% probability that the task will complete on time.
  • P50 Target or P50 Completions” to indicate that tasks, projects, requests, or the like, need to complete on time at least 50% of the time, or that there is at least a 50% probability that the task will complete on time.
  • This intent is mapped to lower-level settings, such as to indicate a thread-level priority and from there to a CPU cache way/profile assignment/resource allocation.
  • the intent On the input/output (I/O) side, the intent may be mapped to network settings to ensure sufficient communication resources are available to transmit and receive the request and response.
  • control loops at various levels in the architecture.
  • the control loops may employ credit systems, utility/cost functions, planning and solvers, etc.
  • the control loops may execute at different speeds depending on how quickly the monitored system needs to adapt.
  • Such control loops are especially important and useful when considering the dynamicity of compute systems. For instance, network traffic may vary daily. If customers have to change the resource requirements themselves, then there is additional burden on them to use the service provider. Additionally, such changes may be difficult because the information needed to make such decisions may not be exposed to the customer. Instead, using the systems and methods described here, the customer need only to specify the intent and the system automatically adjusts the resources. This may lead to cost savings for both the customer and the service provider.
  • Dynamicity in the system also applies to the plans that are generated. These plans have a temporal element. For example, a plan may temporarily (e.g., on the order of minutes) target allocating an abundance of resources to a workload to catch up with an SLA under the supervision of a fast control loop and then over a longer period (e.g., monthly) look to achieve an acceptable and affordable resource allocation pattern with the supervision of a slower control loop.
  • the plan can be either automatically triggered or be partially manually triggered, for instance by first sending the plan as a recommendation to a human operator to enable human-guidance.
  • a plan's temporal aspect can also be useful from a continuous improvement point of view.
  • a plan that satisfies all SLOs in the system-of-systems might be replaced by another plan which also satisfies all SLOs but triggers a different setup, configuration, or set of policies. For instance, to prepare for maintenance, an SLO may use resource more efficiently, make room for incoming workloads/services, or the like.
  • a service provider may deploy a unit of computing (e.g., a pod) with application context meta-data so that the node can, in a fast control loop, make more appropriate application decisions and possibly choose not to deprioritize a low priority workload because of its end-to-end impacting nature.
  • a unit of computing e.g., a pod
  • a Pod In Kubernetes, a Pod is the smallest deployable unit of computing that you can create and manage A Pod is a group of one or more containers, with shared storage and network resources, and a specification for how to run the containers. A pod's contents are always colocated and co-scheduled, and run in a shared context.
  • Resources may be of different types while being in the same category: e.g. high-performance processors (e.g., Intel® Xeon CPUs) versus several reduced-computation processors (e.g., Xeon-Ds), or a single large XPU versus several smaller XPUs.
  • a resource itself may contain different types of sub-resources/components, for instance efficient and performant cores, etc.
  • the system addresses the challenge of administratively governing complex, distributed infrastructure by putting Service Level Objective oriented controls in the hands of cluster and infrastructure administrators and removing the burden of having to specify possibly erroneous low level configuration details.
  • An Admin Policy Controller and an Admin Policy Translation module may be implemented in the orchestration architecture and a workflow to administer multiple tiers of intent driven admin policies may be used in the workload deployment workflow.
  • a closed loop control of administrative policies, including how to achieve them with multiple iterations on imperative configurations, may be used. It can influence workload placement and re-placement in the face of changing policies or policy non-compliance.
  • the system may implement a new model for driving Kubernetes' life-cycle management (LCM) to reflect the needs of the application rather than the assumptions of the Kubernetes administrator.
  • the application is deployed temporarily (to support fast start) and subsequently a new instance of Kubernetes is deployed with the cluster and node level policies that better reflects the needs of the application.
