Definition
vCPE refers to a network architecture model that substitutes traditional hardware-based customer premises equipment (such as switches, firewalls, and routers) with software-based alternatives. Under this paradigm, the capabilities and functionalities of CPE run on standardized hardware or in a cloud environment owned by the service provider, allowing them to control their user’s network services remotely.
How Does a vCPE Work?
VNFs form the basis of vCPEs. Most traditional network services, like malware detection, intrusion, session management, switching, and routing, are starting to be modified into VNFs (software functions). These program functions may be controlled via MSP’s network and directed into the user’s standardized x86 hardware, which hosts the vCPE. The network interface devices (NID) that act as the interface between the MSP network and customer premises are vCPE modules powered by MSP’s NFV.
Despite most VNFs still being Virtual Machine (VM) models of legacy appliances, many well-known networking companies, including Nokia, Alcatel, Huawei, and Ericsson, are creating cloud-based VNF solutions for the vCPE. If the MSP wishes, they may push the vCPE program with a microservices or container design. Moreover, traditional services such as switching and routing are often embedded in the vCPE’s software. Yet, the MSP may extend its functionality by providing modules from VNF vendors and controlling them via a VNF cloud platform.
Advantages of Using vCPE
- Savings: vCPE lowers both operational and upfront overheads by eliminating the need for physical hardware at every location.
- Flexibility and scalability: Network services may be easily modified, provisioned, or scaled up/down via software setups without making physical hardware alterations.
- Centralized management: vCPE streamlines network management, allowing remote configuration, monitoring, and troubleshooting.
- Service quality: Providers can offer a broad range of services without requiring extra hardware. They can easily activate or customize them based on the customer’s needs without requiring additional hardware.
Disadvantages of Using vCPE
- Network dependency: Outages or interference in the network infrastructure may impede the accessibility of services.
- Possible latency: Virtualizing network functions presents extra processing layers, which can introduce latency compared to dedicated hardware.
- Security threats: Centralized network systems need solid security measures such as frequent security patches, encryption, and strict access controls to mitigate vulnerabilities.
- Technical complexity: Implementing and controlling vCPE can be complex.
- Dependency on the service provider: Organizations should pick a dependable and competent service provider that must deliver the needed guarantees, services, and support.
