Asad Naveed, General Manager Systems Engineering, PTCL, Pakistan is worried about bandwidth. In this Q&A we ask him his views about managing data and where he thinks the greatest efficiencies in the network are to be found. To hear from more from him be sure to attend the ‘Network Efficiency and Speed’ track, part of the Network Intelligence stream, on Day Three of the Broadband World Forum taking place on the 21st – 23rd October 2014 at the RAI Exhibition and Convention Centre, Amsterdam.
What do you believe will be the most critical technologies for managing data over the next three years?
Software Defined Networking (SDN), Network Functions Virtualization (NFV), cloud computing and Carrier Ethernet are some of the contenders, but it is hard to say which one will leap forward. However, being an enabler of all of these, Carrier Ethernet will definitely have an edge over others.
In terms of data throughput where do you believe the biggest efficiency savings in the network are to be found?
Firstly I would say incache servers. They can not only reduce international bandwidth, but the customer experience can also be improved due to reduced latency. Cache servers should be placed close to the customers and they should be intelligent enough to sniff high bandwidth applications, which are frequently fetched by the users. Secondly, through peer-to-peer. P2P users may be throttled as per their packages/tariffs, so that they do not abuse bandwidth that may be used by more legitimate users. Thirdly, via backups. When users start backing up huge files, it may put a lot of pressure on the bandwidth. By using efficient compression algorithms and smart back up, this enables backing up of only the new/modified items, so network load can be reduced manifold, bringing a lot of efficiency savings in the network.
Is traffic management causing any kind of friction from your customers?
In certain cases, where customers are used to accessing unlimited bandwidth—they feel constrained when their bandwidth is checked.
How well do you believe networks will cope with the demand for data over the next three years?
As bandwidth demand increases exponentially continual upgrading will be required. Backbone capacity will need to be strengthened and access capacity will have to be increased to match the rising speeds.
What is the most critical thing you are expecting from attending the Broadband World Forum?
Broadband world forum is a global platform and one of the key aspects of this forum will be the sharing of best practice. The forum will also provide a platform to showcase the achievements of PTCL, which is the largest ICT services provider in Pakistan. Additionally, analyzing the gap between vendors and operators shall be a useful experience.
