Hpe routers: revolutionizing network infrastructure

When it comes to managing and optimizing network traffic, having a reliable and efficient router is crucial. Hewlett Packard Enterprise (HPE) routers are designed to meet the demands of modern enterprises, providing advanced features and functionalities that ensure seamless connectivity and enhanced performance.

What is an Enterprise Router?

An enterprise router is a device that connects two or more packet-switched networks or subnetworks. Its primary function is to manage traffic between these networks by forwarding data packets to their intended IP addresses. Additionally, enterprise routers allow multiple devices to use the same internet connection, making it an essential component of any network infrastructure.

Why Do We Need Virtual Routers?

In today's rapidly evolving business landscape, enterprises are increasingly adopting virtual private clouds (VPCs) to reduce network costs and enable faster service rollout. As a result, the demand for virtual routers has grown significantly. Virtual routers, also known as software routers, are cloud-based routers deployed on virtual machines (VMs) to provide routing, switching, security, VPN, and other network communication services.

Virtual routers offer several advantages over traditional hardware routers:

• Cost savings: Virtual routers eliminate the need for dedicated hardware platforms, reducing hardware costs.
• Flexibility: Virtual routers decouple IP routing functions from specific hardware, allowing for flexible deployment on existing standard hardware devices.
• Cloud connectivity: Virtual routers can be deployed in the enterprise headquarters, Point of Presence (PoP), and cloud environments, extending the enterprise network to the cloud and enabling consistent security and management policies.
• Intelligent traffic steering: Virtual routers can optimize enterprises' cloud access paths and improve the user experience by providing application-based intelligent traffic steering.

How Does a Virtual Router Work?

A virtual router operates similarly to a traditional router, running routing protocol instances and having its own dedicated I/O ports, buffer, address space, routing table, and network management software. However, the architecture of virtual routers has evolved with the development of networks.

For example, the Huawei AR1000V, a virtual router deployed in Network Functions Virtualization (NFV) mode, consists of the following key components:

Physical hardware and host operating system:

A universal x86 hardware platform provides hardware resources such as the CPU, memory, NIC, and storage medium, along with basic operating system services.

Hypervisor:

The hypervisor, such as KVM, FusionSphere, or VMware, acts as the intermediate software layer between physical servers and VM instances. It manages VMs, allows multiple VM instances to share hardware resources, and isolates and protects VMs.

vSwitch/PCI-passthrough:

This component enables information exchange between VM instances and external networks, ensuring seamless connectivity.

VM instance:

The VM instance uses the Linux operating system and has independent vCPU, memory, storage, and vNIC resources. It carries Virtual Network Function (VNF) instances, providing routing, switching, security, and VPN functions.

Typical Applications of Virtual Routers

HPE routers, such as the AR1000V, offer a wide range of applications in enterprise networks:

SD-WAN Solution:

The AR1000V can function as an interworking gateway (IWG) to connect to a Point of Presence (PoP) gateway. It can also be deployed as a cloud gateway, enabling one-hop cloud access for enterprises.

Enterprise Aggregation:

The AR1000V can be deployed as a hub at the headquarters of an enterprise or used as an aggregation node of an enterprise network. It serves as the aggregation router, facilitating interconnection and interworking between the headquarters and branches. With high forwarding performance, scalability, and numerous VPN functions, the AR1000V provides secure and reliable network services while reducing network investments.

Hewlett Packard Enterprise routers are revolutionizing network infrastructure by offering advanced features, flexibility, and cost savings. Virtual routers, such as the AR1000V, are enabling enterprises to embrace cloud-based services, optimize network performance, and implement consistent security and management policies. With their robust capabilities and extensive applications, HPE routers are the ideal choice for enterprises seeking to enhance their network connectivity and drive business growth.
