Product Overview

The Cisco®2020欧洲杯体育官方网址 Application Virtual Switch (AVS) is a purpose-built virtual network edge switch for Cisco Application Centric Infrastructure (ACI). Cisco AVS brings the Cisco ACI policy model to virtual infrastructure, thus providing policy consistency across physical and virtual workloads. Cisco AVS also lets you extend these polices to the existing infrastructure, providing outstanding investment protection.

Cisco ACI is an innovative architecture that radically simplifies, optimizes, and accelerates the entire application deployment lifecycle. Cisco ACI uses a holistic systems-based approach, with tight integration between physical and virtual elements, an open ecosystem model, and innovation-spanning application-specific integrated circuits (ASICs), hardware, and software. This unique approach uses a common policy-based operating model across a network that supports Cisco ACI along with security elements (and computing and storage in the future), overcoming IT silos and drastically reducing costs and complexity.

The main benefits of Cisco ACI include:

   2020欧洲杯体育官方网址Simplified automation with an application-based policy model

   2020欧洲杯体育官方网址Common platform for managing physical, virtual, and cloud-based environments

   Centralized visibility with real-time application health monitoring

   2020欧洲杯体育官方网址Micro Segmentation and Distributed Firewall capabilities to secure east west traffic

   2020欧洲杯体育官方网址Operation simplicity, with common policy, management, and operation models across application, network, and security resources (and computing and storage resources in the future)

   2020欧洲杯体育官方网址Open software flexibility for development and operations (DevOps) teams and ecosystem partner integration

   2020欧洲杯体育官方网址Scalable performance and secure multitenancy

The Cisco ACI consists of (Figure 1):

   Physical and virtual leaf switches

Cisco Application Virtual Switch

Cisco AVS is a purpose-built virtual switch for Cisco ACI that’s part of the virtual network edge switch offering of the Cisco ACI leaf portfolio. Cisco AVS is a distributed virtual switch that resides in the hypervisor layer of a virtualized host, providing switching and policy enforcement capabilities in the future. Cisco AVS provides consistent virtual networking across multiple hypervisors (in the future) to simplify network operations and provide consistency with the physical infrastructure (Figure 2). Here are some of the advantages of Cisco AVS:

   Cisco AVS is robustly integrated into the Cisco ACI architecture and supports application network profile (ANP) enforcement at the virtual host layer consistent with the physical Cisco Nexus® 9000 Series Switches.

   2020欧洲杯体育官方网址Cisco AVS is managed centrally along with rest of the Cisco ACI fabric components through Cisco APIC and provides advanced telemetry features to allow end-to-end visibility and troubleshooting capabilities across both virtual and physical devices.

   2020欧洲杯体育官方网址Cisco AVS enables optimal traffic steering between virtual and physical layers of the fabric to enhance performance and resource utilization. For example, if the web and application tiers are located on the same host, Cisco AVS can route traffic or apply security policies between these endpoint groups within the hypervisor itself (in the future). However, if the database is a bare-metal workload that is attached to the physical Cisco Nexus 9000 Series Switch, the application policy is consistently applied at the physical Cisco Nexus 9000 Series top-of-rack (ToR) switches instead.

Cisco AVS is compatible with any upstream physical access layer switch that complies with the Ethernet standard, including Cisco Nexus Family switches. Cisco AVS is compatible with any server hardware listed in the VMware Hardware Compatibility List (HCL). Cisco AVS is a distributed virtual switch solution that is fully integrated into the VMware virtual infrastructure, including VMware vCenter for the virtualization administrator. This solution allows the network administrator to configure virtual switches and port groups to establish a consistent data center network policy.

Figure 3 shows a topology that includes Cisco AVS with Cisco APIC and VMware vCenter with the Cisco Virtual Switch Update Manager (VSUM).
