A Brief Guide to Understanding APN & Its Effect 0n Edge Computing


Application-aware networking is an intelligent network that can track and monitor software applications to improve network functioning and efficiency. Surveillance of a software provider’s usage status, along with tracking of its ram or resource needs, are examples of application-aware networking features.

What Is APN & How Does It Work?

The International Telecommunications Union has sketched out a network architecture for APN. The improved characteristics of an integrated network are meant to give in-depth functioning.

Like some other components of intelligent networking, APN depends on a system that controls network traffic across many levels or planes. Software-defined networking is the concept underpinning application-aware networking (SDN). Modern networks, according to the theory, have three separate planes:

The network plane that transports traffic data.

The management plane is where everything happens.

The plane of management

While the managing plane and controlling plane are sometimes seen as being the same, a software-defined networking design separates the two by maintaining the management plane connected to network hardware while making the control plane a software-driven layer.

Shifting the control plane from a physical network connection to a software connection allows planners to do more with software programs, such as promoting application aware networking and developing meta-level traffic management solutions.

APN And Edge Computing

Edge computing refers to deploying service facilities close to the user’s location to deliver better network and computer capabilities.

Edge computing services may be implemented not only at the edge data center but also in network equipment, allowing for the confluence of network and computing and putting forth the needs for the technological merging of diverse sectors.

While the network’s demand for various applications must be disclosed, on the other hand, the network must be aware of computing power and guide traffic along the proper way to the appropriate locations.

The present network can identify only a coarse granularity of application demands. When application demand is strong, a high network load, latency, and reliability of applications, particularly mission-critical implementations, are frequently compromised.

The goal of APN is to tackle the problem of network and application mutual recognition. APN allows the network to be mindful of the applications’ needs at a fine granularity and then direct traffic to the proper network path (if one exists) that can meet those criteria. Or create another exclusive network path that is not impacted by other application domains.

User terminals, edge gateways, and edge data centers are all part of an edge computing network. In a 5G network, the edge gateway might be the UPF. Because the edge cloud infrastructure is typically closed to the consumer, it can deliver low latency services.

The app-aware edge, app-aware process head-end, app-aware process mid-point, and app-aware process end-point are all examples of application-aware networking. The client sends the user’s request to the server, which flows through all of the APN network’s nodes.

The app-aware edge function may be installed in the edge gateway, allowing the edge gateway/app-aware edge to identify client request traffic and send it to the edge data center through the APN. In some circumstances, the edge data center’s response will not be forwarded to the original client but rather to another client via the APN.


Summing Up:

To reap the total value of edge computing, the network must be aware of the apps’ requirements to direct traffic to network channels that can meet those requirements. APN is the missing component of the jigsaw that connects applications and networks to meet the demands of edge services, allowing edge computing to realize its potential fully.
