Netsocket Virtual Network
The Netsocket Virtual Network architecture is a fusion of the best principals of cloud hosting, Network Functions Virtualization (NFV) and Software-defined Networking (SDN), applied to real-world solutions at the edge. All network functions are virtualized, management and orchestration is cloud-hosted, and the networking components are layered in a three-tier SDN architecture. Netsocket delivers NVN components in all three layers of the SDN architecture spanning the application, controller, and infrastructure layers. Within these layers are virtualized system components – the vFlowController™, vFlowSwitch™, vNetCommander™, and vRemoteAgent – that provide a layered connection to the underlying network,
enabling system administrators to more easily view and manage what is going on in the network.
The Netsocket Virtual Network delivers:
A Completely Virtualized Network Implementation
NVN’s three-tier architecture spans the application, controller, and infrastructure layers. Within these layers are virtualized components – the vNetCommanderTM, the vFlowController™, and the vFlowSwitch™ – that each run in virtual machines on commodity x86 server platforms.
vNetCommander – Powerful, Unified Network Management
NVN’s orchestration and management application is the vNetCommander™. vNetCommander enables system administrators to install, configure and operate a complete Netsocket Virtual Network in a matter of minutes. Within the application layer, it provides robust, unified network management and enables centralized administration of NVN components. Its elements include a web-based GUI and template-based installation, bulk-provisioning, and software upgrade orchestration functions. Day 2 configuration operations are simplified through the use of a GUI. No knowledge of CLI is required to manage the NVN. vNetCommander provides automated modification of router, switch and tunnel attributes, including quality-of-service (QoS) queue management, traffic filtering rate limiting, and routing protocol configuration. vNetCommander’s workflow automation for installation, bulk provisioning and software upgrade orchestration represents a dramatic reduction in the time required to design, install and initially configure a highly-scalable routed network.
vFlowController – Virtualized Routing, Firewall and Tunnel Functions
Residing at the controller layer, the vFlowController application runs in a virtual machine on a commodity x86 server platform, providing control for layer 3 packet flow. The vFlowController supports IPv4 and critical routing protocols (BGP, OSPF), stateless packet filtering, and includes intrinsic virtualized routing, firewall, and encrypted, inter-site tunnel functions to support critical enterprise needs. A primary advantage of the intrinsic nature of these features is their close coupling with flow control functions. This pairing delivers performance benefits above and beyond what can be delivered through a common application-layer API, such as a traditional SDN northbound API.
vFlowSwitch – Virtualized Packet Forwarding
Within the infrastructure layer is the vFlowSwitch, a virtualized application that is responsible for layer 3 packet forwarding. The vFlowSwitch runs in a hypervisor virtual machine and is coupled to layer 2 virtual switches, a native component of the hypervisor environment. In the case of Microsoft’s HyperV, that virtual layer 2 switch is their vSwitch. One or more vFlowSwitch modules can be associated with a parent vFlowController, based on individual network requirements.
vRemote Agent – Automating Installation, Provisioning and Monitoring
The vRemoteAgent automates the local installation, initial provisioning and subsequent monitoring, fault isolation and configuration at individual sites. The vRemoteAgent also orchestrates all local software upgrades initiated by the vNetCommander application. Acting as the local agent of the cloud-based vNetCommander, the vRemoteAgent facilitates communication between the vNetCommander and the vFlowSwitch and vFlowController. It is hosted in a virtual machine of a hypervisor operating on each site’s x86 platform. By way of the vNetCommander GUI interface, the vRemoteAgent allows for the creation of a secure remote diagnostics tunnel so that MSP service desk personnel can remotely manipulate a restricted set of workflows. In addition, it is securely architected so that customers and service desk operators do not have unrestricted access to the operating system or to NVN components.
