MPLS: MPLS refers to the technological operation that is more properly known as multi-protocol label switching. Essentially, MPLS is an operating scheme that is used to speed up the flow of traffic on a network by making better use of available network paths. The main thrust of the idea is to define or designate the proper path for each function so that the opportunity for bottlenecks within the network are minimized. (Source:

The Falling Costs of Wide Area Networks

Section: Research
Based on pricing data gathered from a selection of Service Providers, we survey what connectivity options are affordable for small and medium-sized businesses. In particular, we examine where wide area networks are today, in particular MPLS and its impact on Wide Area Network costs and based on historic trends, project where they are headed.   We argue that given current trends we are entering an era where sma ...   read more

Managing 21st Century Networks - A World of Convergence

Section: Research
The Internet Protocol (IP) - used for transmitting data across networks everywhere - has moved beyond its origins. Once one of many, it has become a near standard for all types of computer communication. It is used pervasively, transmitting data to and from a multitude of devices ranging from those in our pockets to spacecraft circling distant planets. Arguably IP is the most successful open standard ever, but as network communications converge under a single standard used for an increa ...   read more

Alternatives to BT leased lines

Section: Articles
A leased line is defined as a dedicated high-performance circuit leased by a common carrier between a customer and a service provider’s network. It is rented on an annual basis and usually carries voice and data or both. It can be used for internet access or for a private connection between two customer sites. Compared to other internet connectivity options such as DSL products, leased lines are relatively expensive but are supported by a ...   read more

Compare MPLS and Ethernet for Wide Area Network solutions

Section: Articles
A WAN (Wide Area Network) is a computer network that covers a broad area and its communication links can traverse across metropolitan, regional or national boundaries. Protocols such as Packet over SONET/SDH, MPLS, ATM and Frame relays are often used for the delivery of circuits that are used in WANs.   Multiprotocol Label Switching (MPLS) is a mechanism in high-performance telecommunications networks which directs and carries data from ...   read more

Considerations for Site to Site VPNs

Section: Articles
  A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or individual users with secure access to their organisation's network. The intention of the VPN is to offer the same kind of connectivity options that users receive from leased lines but at lower costs.   ...   read more

MPLS IP VPN explained

Section: Articles
MPLS is a highly scalable, protocol agnostic, data-carrying mechanism in high-performance telecommunications networks which directs and carries data from one network node to the next. It belongs to the family of packet-switched networks and here data is transferred in the form of ‘Packets’ and the data packets are assigned a label and the content of the label alone influences packet forwarding decisions and there is no need to ex ...   read more

Network Connectivity: Considerations on Moving into the Cloud

Section: Articles
Network connectivity, although not widely perceived to be a major obstacle to the adoption of Cloud services, continues to rear its head during discussions of Cloud adoption risks. These concerns are not without cause: many Cloud services are wholly dependent on stable network connectivity for functionality, availability, responsiveness and overall p ...   read more

What is the future for leased lines?

Section: Articles
A leased line is service contract between a provider and a customer, whereby the provider agrees to deliver a symmetric telecommunications line connecting two locations in exchange for a rent – hence the term ‘lease’. In the UK leased lines are sometimes referred to as 'Private Circuit' or 'Data Line'.   Leased lines are stated to be more suited for businesses that conduct business online and demand f ...   read more
