The ever-increasing demand for the Data-Center and network virtualization has its ramifications on the Data Center interconnect (check out Cloud Cover). It has gained the attention of the service provider’s network architecture making them think in the direction of load-sharing and distributed workloads. It has also become a way to connect various Data Centers in the cloud using SDN to allocate resources as per the requirement, automatically.

There was a time when Data Center interconnect (DCI) used to be simple. But due to the many technological advances and the availability of various options, there is a lot of confusion in the market. First, let’s take a look at the Data Center interconnect market:

Intra-Connections-The intra Data Center interconnect refers to all the connections within the Data Center. They can be within one building, or between Data-Center buildings within the campus. The connections may be at a distance of meters to few kilometers.

Inter-Connections-These refer to the connections that are between the 10km-80km range. Undoubtedly, the connections may be far apart, but inter-Data Center connectivity market is focused within this range.

There are Data Centers situated to serve the entire continent and there are others focused in a specific metro area.

Case-Study (Online Retailer)

You are a global retailer, and you might have several thousand transactions running in a second. When the Data Center is far away, the data is more secure from the various natural disasters. But, then there is a challenge that comes with greater distance. The transactions that are in-flight may get lost due to latency.

So for online transactions, there is a local Data Center (primary Data-Center), and the other is a secondary Data Center that’s almost 80Km away. The benefits, in this case, are dual. First, your transactions will not be affected by the distance and the data is secure. Second, none of the transactions are lost due to latency. So in the worst case, only a small number of transactions might get affected or lost.

The traffic may be within Data-Centers, or between two Data-Centers for the load-balancing. Now the two important traffic categorization:

1. East-West Traffic: The traffic between Data-Centers is referred as East-West.
2. North-South: The traffic to the user is referred to North-South.

Which DCI Challenges Have To Be Overcome?

There are many challenges that have to be overcome. Let’s take a look at some of them.

Distance: The DCI applications vary greatly in size and scope in response to the Data Centers that may be dispersed across the globe or metro area or around a country. So it becomes critical to carry most of the bits farthest, but when the distance increases the latency increases as well. While choosing shortest route may minimize latency, bad equipment may also lead to latency.

Connection Capacity: The Data Centers store and deliver applications. The data sets that are coming in a Data-Center or leaving it may be very large. The range may vary from few hundred Gigabits to Terabits. To handle such large data, the equipment should offer reliable and high-capacity connections. It’ll make sure that they may quickly scale to address the spikes in traffic.

Data Security: Data Centers store a large amount of critical information. It demands that the Data Center connections are reliable, safe, and encrypted to avoid costly breaches and also data losses. While the security of stored data is crucial, what’s more, crucial is the security of in-flight data.

Automated Operations: As we know, manual operations may be labor-intensive, complicated, slow and may be error-prone as well. So it is very much imperative that complexity and lower speed of connection that arises out of manual operations may be minimized by moving towards automation. It shouldn’t take much time to establish a connection between Data-Centers and shouldn’t require on-going manual operations.

Rising Costs: When a large stream of data enters and leaves the Data-Center, it should be carried out in the most cost-efficient manner. If the Data Centers remain viable, the costs shouldn’t rise in the same way as the bandwidth. To take care of these issues, the solutions in high-speed networking should offer a solution that connects Data Centers at the lowest cost per bit.

The internet can be accessed in many ways, as evidence in the form of the evolution of the internet connections over the last few years. Today, the broadband is usually considered as the most popular medium for accessing the internet, especially in homes. However, when it comes to larger establishments and commercial spaces such as hospitals, corporate offices, and colleges, internet leased lines are preferred. Why is that, exactly?

Defining internet leased lines and broadband connections

An internet leased line is a premium, dedicated internet connection between the local exchange and one’s premises. Usually delivered over fibre, an internet leased line, which is also otherwise called as a private line, data circuit, a dedicated line or an ethernet leased line, provides symmetrical, uncontended, and identical internet upload and download speeds. An internet leased line has a fixed bandwidth and isn’t dependent in contention with other users.

Broadband, on the other hand, is a non-dedicated connection between the local exchange and one’s premises. Not only does it have a variable bandwidth, but it also provides asymmetric speeds which are slower for uploads and faster for downloads as well as is subject to contention with other users.

Difference between internet leased lines and broadband

• Connection: Internet leased lines and broadband connect to the business premises in different ways. While they both are transferred via cables, the difference lies in how. An individual gets their internet from the local cabinet/box on the street/apartment building where one lives. That box contains a copper-wire or fibre connection to one’s premises and delivers the internet. Thus, the exchange is via a series of cables in both cases. However, in broadband connections, cables are split between all other local premises, while leased lines are dedicated circuits coming only to your premises – that means no sharing in leased lines
• Consistent speeds and contention: Since various premises share the same cable split ‘n’ number of ways in broadband, the speed is also affected. So, even if one gets a 76Mbps connection, the speed varies according to how many other people are using the broadband at the same time. Realistically, at peak time, one might be getting a much slower speed if everyone is using unlimited downloads. However, with an internet leased line, there is no slower speed because there is no contention with others. Even if you have only a 10Mbps connection, you’re getting the 10Mbps in its entirety.
• Reliability and SLAs: When it comes to issues such as the internet being down, for how long can you work without it? This is where Service Level Agreements come in. Some broadband providers don’t even provide SLAs, but do mention about the internet being fixed as quickly as they can in their service terms. However, one might have to wait for a few days. With internet leased lines, users can expect strong, to-the-point SLAs with better reliability. In fact, leased line issues might even get fixed within a matter of a few hours, while of course, keeping the issue in mind.
• Bandwidth choices: When it comes to internet leased lines, users can take their pick from a wide range of bandwidth choices, right from 64 Kbps and 128 Kbps to 2 Mbps, 80 Mbps, and even as high as 155Mbps. The choices are much more restricted and lesser when it comes to broadband.

So, while broadband might be cheaper than an internet leased line, but it certainly isn’t a match for the latter when it comes to the above-mentioned aspects. When one is considering a new internet solution, the best thing would be to analyse what you exactly need and compare the options for both broadband and internet leased lines before zeroing in on one.

There are numerous internet leased line providers in India and Sify is proud to be one of the oldest & widest network coverage providers.

A lot is being written these days about the increasingly important role of communication and collaboration services in running a business smoothly. As the world becomes more connected and doing business across vast geographies becomes the norm – the expectation of the employees, clients and end customers also rise – employees and clients demand to be connected 24×7 from anywhere in the world and customers expect near instantaneous resolution of their problems.

In this scenario, most organizations need to revaluate their collaboration systems. Several ICT players have harnessed technology to provide solutions that allow real time collaboration across devices – making it easier for people to work together without wasting time and money in traveling across distances.

Many of you might wonder what services are available under the umbrella of collaboration services and this is just what we will address below.

Components of Collaboration solutions

A comprehensive end-to-end Collaboration solution has three main components –

Audio Visual Collaboration Solutions

A few years ago, AV collaboration meant basic video conferencing solutions from fixed meeting or boardrooms, but service providers are now leveraging latest digital technologies such as cloud computing to offer exceptional communication and collaboration services to users, where they are – either within office or outside.

This includes a Wide Range of Services and Solutions with Capex and Pay-as-You-go models–

1. Basic Video conferencing
2. Mobility solutions to connect people on the go
3. High end bridging solutions
4. Large display solutions for niche applications such as NOCs and digital signage.
5. AV integration solutions for creating immersive communication environments for large areas such as board rooms, VC rooms, auditoriums etc.

Collaboration services also offer additional functionalities and benefits – recording and streaming facilities, integration with business applications, flexible and user-friendly interface etc. And businesses have added flexibility in terms of using these services either as an on-premise, hosted or hybrid model.

Hosted Contact center solutions

The second element of collaboration services is tailored to the needs of businesses – small, medium or large – whose business models revolve around customer interactions which necessitates the need to run customer care centers.

Customer experience during their interactions with provider organizations are key business drivers and hence critical to businesses. To enable enhanced customer experience, Contact center solutions have evolved over years with the help of state-of-the-art technology. These technologies are normally Capex intensive. However, today businesses can opt for Contact center-as-a-service model which has no upfront CAPEX costs and is completely flexible and scalable. This as-a-service model allows businesses to outsource all the technological aspects of contact centers and concentrate on their core business operations.

VoIP security and TDM to IP conversion with SBCs

VoIP services have taken on a mission critical role in many organizations, hence it is imperative to protect and isolate the VoIP infrastructure from external threats and allow seamless communication between multiple voice devices.

VoIP security forms an important component of Collaboration services. With SBCs (Session Border controllers) organizations can centrally manage VoIP policies and bandwidth for VoIP devices and applications and protect the network from cyber-attacks.

One of the hallmarks of a successful enterprise is how well its employees work together as a team. Teamwork and Collaboration is essential for running a successful organization, more so in today’s global workplace. Professional collaboration solutions based on the latest technology delivers on several fronts – cost, productivity and flexibility – and for many organizations is one of the smartest business moves for staying competitive in the current global marketplace.

The world over, communication – reliable and secure – is taking on a more critical role in the functioning of organizations and businesses. The more geographically spread your organization is, the more important it becomes to keep communication networks up and running.

Voice Over Internet Protocol (VoIP) has gained tremendous traction over the last decade and has become a popular choice for organizations looking for cost-effective and reliable communication networks to manage their growing business – VoIP services market is predicted to expand 10 % every year until 2021 and touch $140 billion.

What is VoIP (Voice over Internet Protocol)?

VoIP services use Internet connections to make phone calls. The analog voice signal is turned into data packets and transmitted over the Internet, enterprise local networks or Wide area networks. Apart from voice data, VoIP also transmits multimedia content over IP networks.

How does VoIP work?

VoIP has become an increasingly popular choice for business communications and provides a stable alternative for traditional telephone networks known as Public Switched Telephone Networks(PSTN).

VoIP provides a reliable and secure communication channel with highly cost-effective models. To understand how VoIP can achieve this, one needs to look at the technology behind the services.

VoIP uses a codec to encapsulate audio into data packets and transmits them across an IP network and decapsulates them back into audio at the other end of the connection. VoIP uses standard codecs by the International Telecommunication Union, such as G.711 for transmitting uncompressed packets, or G.729 for compressed packets. This compression is typically used to decrease bandwidth requirements.

After it is encapsulated onto IP, voice data is transmitted via the real-time transport protocol or through its encrypted variant, secure real-time transport protocol. The most common communication protocol is Session Initiation Protocol (SIP) and is used for signaling that is necessary to create, maintain and end calls.

In an enterprise setup, VoIP emulates the traditional telephone networks with dedicated instruments – endpoints include applications running on mobile devices or dedicated desktop VoIP phones. VoIP is also available as a computer to computer service wherein you don’t need any extra hardware – calls can be made directly from the computer with just a microphone or a soundcard – the most popular example of this is Skype!

In many organizations, there may be an existing PBX system and VoIP system can use a SIP codec to connect with the PBX and allow it to manage user phone numbers; gateways to connect networks and provide failover in the event of a network outage.

VoIP networks have several other components such as session border controllers to provide security, call-policy management and inter-operator network connections. VoIP also has a host of additional functionalities which help users and management to operate smoothly – these are location-tracking databases for call routing and management platforms to collect call-performance statistics for voice-quality management.

Conclusion

A peek into the VoIP technology lays bare the reason for its popularity, especially among businesses – while cost savings may be one of the main reasons for migrating to VoIP (on an average, businesses can save between 50 – 75 % after switching to VoIP), businesses have consistently seen enormous jumps in productivity thanks to additional functionalities such as unified communication and telecommuting. In the current market scenario, where customers expect quick responses and a seamless customer experience is key to business success, VoIP has quickly become the only communication choice for most organizations.

During the early days of the VoIP (Voice over IP) technology, it was surrounded by skepticism over its long-term viability and its suitability across industries. However, the past decade has seen VoIP being firmly recognized and implemented across businesses of every size and industries of every nature.

VoIP in its current evolved form offers many such features that help provide increased functionality, cost-effectiveness, and improved efficiency. Beyond the basic options such as voicemail, call waiting and call forwarding, there are many strategic features that empower businesses.

Security

Security for its communications is fundamental for all businesses. VoIP offers that by adding a layer of security for all voice communications and encryption for media and other data. Most Voice over IP providers use Multiprotocol Label Switching (MPLS) at both ends, ensuring greater security for the users.

Mobility

VoIP solutions enable remote operation, giving the employees and managers, spread across vast geographies, access to constant and reliable communication, even when they are away from their offices. It reduces the requirement to travel, allows them to telecommute and increases team productivity. It also presents a wide reach across borders for the businesses at a nominal cost.

Scalability

As against a traditional alternative, where scaling up translated into expensive hardware and access to basic features entailed a minimum set-up size, VoIP uses the limited resources of money, space and manpower more efficiently. There is a reduced requirement for infrastructure freeing up physical space. There is a built-in flexibility of ‘pay per use’ that allows a business to scale up or down without the prohibitive expense of redundant infrastructure/ related software or the associated time to implement and operate the revised solutions.

Unified Communications

Unified communications (UC) fuses and brings together all corporate communication channels such as voice, chat, video, mobile and email as a part of a single integrated suite. UC, when linked with the right business processes, can dramatically amplify productivity. This is especially significant in industries with a sizeable and continuous customer interface as it provides customers with greater flexibility while communicating with the company.  UC makes it possible for businesses to maintain a single easy-to-manage network instead of wrestling with different infrastructures for voice, data, and video.

Analytics

VoIP provides the businesses with an option for analysis of their interactions with their employees and the customers. The nature of the industry that these businesses operate in, determines the level of analytics that they need. However, the information is made available for all interactions with the VoIP solution. The analysis could be used to benchmark call efficiency KPIs, reduce turnaround time for troubleshooting, track call quality, agent or team specific metrics or even for compliance purposes. VoIP systems offer call recording and built-in reporting tools to support a business’ unique objectives.

These features and functionality offered by a VoIP (Voice over IP) solution can positively impact team productivity, customer relations, and core business operations. VoIP solutions can achieve this by enabling employees to work efficiently while juggling multiple devices, working from remote locations or constantly traveling for work.

Additionally, the constantly evolving nature of technology ensures that innovative new features are incorporated in the VoIP solution on a regular basis. As VoIP solutions ably support the new environment and scale quickly as the business grows or shrinks, it would have a significant influence on businesses over the next couple of decades.
