With the advancement of IP broadband access technologies, carrying video streams on different broadband platforms has increasingly become a viable option for service deployment. |
| |
An Internet Protocol (IP) Broadband TV service has many advantages compared to other TV services, such as Cable TV. IP's inherent full interactivity enables a wide and unique variety of services and applications to be launched over this platform, such as interactive applications. |
| |
However, the technological requirements and considerations for IP local Channel are different to conventional TV services. The assessment of existing network elements and the choice of network architecture is a crucial part of a IPTV service deployment as a large number of video streaming devices and servers have to be deployed to support the operation of the IP Broadband TV headend. |
| |
When assessing the suitability of upgrading existing IP networks to video services, operators should check their network against the following parameters for network performance excellence: |
|
| SCALABILITY |
| SECURITY |
| MANAGEABILITY |
| QoS |
| AVAILABILITY |
|
| |
SCALABILITY:Ensuring Maximum Scalability for Future Growth The scalability of an network is an important aspect of network design in order to achieve economies of scale moving forward. |
Operators who are starting out to deploy a network service should begin by building a small system and scale it alongside the growth of the business. The components adopted in the Network service architecture should be based on a building block model where all components are able to operate within a small system as well as a large system. This applies to both centralised and distributed network components. centralised and distributed network components. |
| |
MANAGEABILITY:Maximizing Performance Management Network service components are commonly made up of equipment from different manufacturers which usually implement functionalities differently. This is why the role of systems integration is extremely important for a smooth launch and quick growth of a Broadband service. |
| |
AVAILABILITY:Fast Network and System Recovery is Essential for Quality Performance
Just like other Broadband services, high availability is key for a viable network service. In case of breakdowns, network and video service equipment must be able to recover as quickly as possible to minimise the effects on subscribers. A good redundancy scheme can help to ensure a non-interrupted failover and thus seamless service delivery. For example, if a video server breaks down during a subscriber’s Video-on-Demand (VOD) session, the redundant video server should take over the VOD session instantly, ensuring that the failover is not interrupting the subscriber’s viewing experience |
| |
Security: Protecting Your Mission-Critical Networking Services Protecting the system is just as important as protecting the network equipment and computer servers against any security attacks, whether unintentional or malicious.
A system is susceptible to common security attacks such as IP Spoofing, Denial of Service (DoS), including UDP and TCP types, false authentication, unauthorized access and packet sniffing. Operators should identify all sources of security risks and analyse hardware and software capabilities of the network system in order to tackle them. Most attacks can be prevented by the inherent security features of the network transport devices, however violations such as packet sniffing of video streams can only be defended by specialist content security, conditional access (CA) and digital rights management (DRM) systems.
