INPUT – Programmability at the Network Edge for Personal Cloud Services 2

Cloud as the Center of Digital Everyday Life

Personal Cloud

Storage

StreamingCloud Application

Online Office

Motivation

Trend: more and more functionality and services are moved to the cloud

(5G, personal servers, business applications, ...)

In the past: simple storage now (full-featured) application

Applications are becoming better tailored to the user

Users want to access them 24/7 everywhere

Advantages: Usable from anywhere, nearly unlimited resources, 24/7 connectivity,

fast and preconfigured installation, energy savings, cloud storage

Examples: Office-in-the-cloud, data processing for smartphones/tablets/sensors

with limited resources, personal content streaming, tv set-top box

Drawbacks: Challenging requirements for maximum end-to-end response time


Characterization of a Personal Cloud Service

Definition

User-specific application functionalities are outsourced to the cloud

Often 1:1 mapping of a personalized cloud instance (VM) with one applications

for

– storing, processing, providing, or streaming of personal content

Replaces some functionalities of (or the entire) home device

Helper to circumvent resource bottlenecks of home network, home equipment

Special characteristics

Lightweight part of the application must remain with the user, such as input and

output, often implemented through web technology

and/or streaming

Very challenging requirements for

maximum end-to-end response time

Common features

Web-based configuration, pre-configured

Business model: users pays per cloud resource usage over time

Multi-faceted challenges to the Telco and

Cloud Service Provider

Challenge: Instantiation of service

and resource planning in the cloud

(Management and Orchestration)

Challenge: Ensuring the Quality of

Service

(Distributed Cloud or Edge Cloud?)

Challenge: Access to personalized

services

Consequences for Telco and Cloud

Assuming this principle

is daily use high

number of small,

heterogeneous services

with high demands

Limited cloud resources:

• Initial service deployment

according to available

resources and service

demands

• Service „breathing“:

resource demand of

service can change

• Overcome too ossified and

obsolete Internet

architecture

• Provide LAN connectivity

• Acceptable performance

by leveraging available

resources at the edge

• Cloud service is no

longer with the user but

on the Internet

• Respect maximum end-

to-end response time of

applications

• Caching is difficult


Programmability at the Network Edge for Personal

Cloud Services


INPUT Approach

The INPUT project will overcome current limitations in the cloud

service design due to the underlying obsolete network paradigms

and technologies, by:

using the computing and storage capabilities of network appliances to

allow users create private clouds “in the network” between user

and data center;

moving cloud services much closer to end-users and smart-

devices, thus avoiding useless network infrastructure overloading.

exploiting the energy consumed in network appliances more

efficiently than in traditional cloud computing scenarios;

Extending the programmability of network devices to make

them able to host cloud service applications, which will

cooperate with the ones in users’ terminals and datacenters to

realize the aforementioned cloud services.


Main Approach

Personal Network

Personal Cloud Services

for different functionality

Personal Networks should provide users with the perception nearly

comparable to the one at home
