SD-WAN (Software Defined WAN) is a private network technology based on virtualization, to speed-up deployment and upgrades, and to integrate the best of two worlds : IP-VPN and quality of service (but costly in MPLS networks) Internet with high performance and versatility , but poor reliability. SD-WAN drivers are the transfer of applications and machines into private and/or public Clouds, the need of very high data rates for non-critical applications, and time-to-market. |

The traditional solutions were put in place to allow employees to carry out their missions from their home or, more generally, without being physically present at their Workplace. They were originally designed for specific and small populations (commercial, staff on-call) and over defined periods of time (part-time, short-term crises). Faced with recent crises, these solutions have shown their limits: inability to generalize them to a much larger population in the event of lockdown, performance problems, insufficient availability, functional limitations which do not allow access to all IT resources of the company, limited interworking with customers, suppliers and partners of the company, poor ease of use for the collaborators discovering these solutions, support for the users nonexistent or badly dimensioned. Unitic supports its customers in the deployment or upgrade of teleworking and nomadism solutions, taking into account the key points:

PSTN replacement is a major project for companies in the next five years. Traditional phone networks will be progressively shut down starting from 2017 : therefore, corporations must now define their strategy to move to all-IP networks.. We can assist you to inventory and catalog your sites, existing voice and data connections, PBX and special lines (fax, safety, alarm…). We can then help you build a technical and Financial strategy to move your communications services to an all-IP solution. Such a an architecture can be more or less convergent but will definitely reduce the number of PBX, Unified Communications solutions and also the number of providers. Eventually, we help you define the transition schedule, both short term for your new locations, and medium term for a smooth transition of existing sites. This schedule also includes tender and contractual phases. |

When redesigning communication infrastructures, existing solutions cannot be completely removed, either PBXs, end-user equipments, connections to operators or services rendered to users. On this occasion, it is nevertheless desirable to streamline the solutions to contain the operating and investment costs and bring new services to users. In this context, Unitic can advise you on what role should be assigned to PBXs in your future architecture, how to interface them with your authentication and messaging solutions, how to connect then to Unified Communications platforms, whether hosted in your organization or in the cloud (Microsoft, Google, BlackBerry, Amazon) and evaluate the impact on WAN data networks in terms of speed, security and reliability. |

IP Centrex is an outsourcing solution of your legacy PBXs, usually located inside the company premises. Common telephony services are still available (directory, short numbering, 3way parties, call forwarding, voicemail…). Each branch of the company is linked to the Service Provider Intelligent Platform through a regular data link (DSL, Leased Line…). Internet access and data networking can optionally be implemented on this link Advantages for the company : low CAPEX, unique multiservice link, outsourcing of operation and maintenance. The drawbacks : TCO should be carefully calculated for medium and large sites. Some usual functionalities may not be supported : fax, tele-alarm, tricky integration with Directory Services and internal IS applications. |

Local Loop Unbundling (LLU) allows alternative Service Providers to use the copper network of the incumbent operator. This network is made of copper wires connecting companies premises to the operators’ networks. This way, the end customer does not need to have any contract with the incumbent operator : the alternative operator is the single point of contact for all telecom services. LLU covers five technical solutions, three of them usually available to end users :

An IP-VPN (Virtual Private Network) is a wide area network (WAN) dedicated to one corporation and built upon a multiservice operator’s network. The company does not actually rent physical leased lines but rather a capacity and SLAs between its various locations. Routing functionnalities are embedded in the VPN ; there is no need for the company to purchase its own routers. Such a network can have an international span across several countries or continents. Security features (authentication and cyphering) are also embedded in the VPN to prevent eavesdropping and intrusion. Protocols associated to IP such as IPSec or MPLS are traditionnaly used and may be mixed to improve geographical coverage.
IP-VPNs can be implemented over DSL or fiber-optics and have redundancy and failover features. However, they may prove substantially more costly than Internet-based connections, which are a viable alternative if throughput and reliability are not of the essence. |

VPLS (Virtual Private LAN Service) is a metropolitan level-2 interconnection data service, national or international. It streches out the company Local Area Network to remote locations and provides natively point to multipoint connectivity. It is generally implemented over an MPLS network operated by a Service Provider. |

EFM a.k.a IEEE 802.3ah, stands for Ethernet in the First Mile. It allows a service provider to offer native Ethernet connectivity, without using any encapsulation protocol such as ATM in the case of SDSL links. It provides throughputs of 20Mbit/s using 4 pairs of copper lines. Conversely to ATM, if one of the pairs is cut, the service is still provided, with lower performance however. |

5G have been set by the ITU and encompass ugely increased data volumes, overall data capacity and user density, massive Machine-type Communications for the IoT, requiring low power consumption and low data rates for very large numbers of connected devices, and ultra-reliable and Low Latency Communications to cater for safety-critical and mission critical applications 5G standardization has already started in 3GPP. The first standards will be approved in 2018. |

4G acronym encompasses a variety of norms and standards related to the 4th generation of mobile telephony. 4G relies on radio technologies such as IMT-2000 and IMT-Advanced (including LTE and LTE Advanced) and are characterized by :
