Software-Defined Networking (SDN) Definition

What is SDN?

The physical separation of the network control plane from the forwarding plane, and where a control plane controls several devices.

---

Software-Defined Networking (SDN) is an emerging architecture that is dynamic, manageable, cost-effective, and adaptable, making it ideal for the high-bandwidth, dynamic nature of today's applications. This architecture decouples the network control and forwarding functions enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services. The OpenFlow™ protocol is a foundational element for building SDN solutions. The SDN architecture is:

• Directly programmable: Network control is directly programmable because it is decoupled from forwarding functions.
• Agile: Abstracting control from forwarding lets administrators dynamically adjust network-wide traffic flow to meet changing needs.
• Centrally managed: Network intelligence is (logically) centralized in software-based SDN controllers that maintain a global view of the network, which appears to applications and policy engines as a single, logical switch.
• Programmatically configured: SDN lets network managers configure, manage, secure, and optimize network resources very quickly via dynamic, automated SDN programs, which they can write themselves because the programs do not depend on proprietary software.
• Open standards-based and vendor-neutral: When implemented through open standards, SDN simplifies network design and operation because instructions are provided by SDN controllers instead of multiple, vendor-specific devices and protocols.

Testing Synchronization in UMTS Networks

Testing Synchronization in UMTS Networks pdf

We know from experience that correct synchronization of network nodes is essential for Quality
of Service. The quality of the carrier frequency of the radio interface is critical, in order for us to
guarantee a low level of interference between adjacent cells. Furthermore, when a radio
interface is based on TDD, it is vital that all the different Nodes B are synchronized
together.Another service that will undoubtedly require high-quality synchronization is Location.

UMTS Network Design & Cost

UMTS Network Design & Cost pdf

A design exercise was carried out in order to assess the deployment cost of national UMTS networks in the 900 MHz, 1800 MHz and 2100 MHz bands. The design was carried out to provide voice & data coverage to 95% of the population and 80% of the geographic area of the Republic of Ireland. The number of base-station sites required for a 900 MHz network was found to be 533, 1013 for an 1800 MHz network and 1243 for a 2100MHz network.
Dimensioning was then carried out for an assumed subscriber profile giving a requirement for seven RNC’s to switch 4.28Gbps of traffic. The core network was then also dimensioned.
In estimating the cost of network deployment, the following network model was taken into account.

Detailed pricing was examined for turnkey rollout, the Radio Access Network (RAN), the core network, the service layer, mediation, provisioning, middleware & applications, network management and customer management.
All hardware pricing are estimates. Vendors do not publish pricing, and hardware costs are generally blended into turnkey packages including services and O&M. Vilicom has estimated pricing based on the projects on which it has worked internationally. The following costs were calculated based on recent network deployment costs for UMTS networks internationally.
