Ethernet

Ethernet: Ethernet is a family of computer networking technologies for local area networks (LANs) commercially introduced in 1980. Standardized in IEEE 802.3, Ethernet has largely replaced competing wired LAN technologies. Systems communicating over Ethernet divide a stream of data into individual packets called frames. Each frame contains source and destination addresses and error-checking data so that damaged data can be detected and re-transmitted. (Source: Wikipedia)

Compare DSL, Leased Line and Ethernet – Internet Access Buyers Guide


Section: Research
This buyer's guide is for those that need help with deciding on the right business connectivity solution.    Choosing which type of dedicated internet access service is the best fit for your organisation depends upon your budget, your organisation’s connectivity and bandwidth needs, the type of network applications which are most typically used and the future plans of your organisation.    Traditional ...   read more

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

Don't forget the network


Section: Research
The overall IT networking requirements of a given organisation are not provided as a single utility. Instead they comprise a constantly evolving patchwork of technology and services, some maintained in-house and some provided by third parties, the availability and performance of which are often taken for granted until something goes wrong. Over time this ‘network’ has become embedded in nearly every business process; when the network fails the processes fail too. To prevent this ...   read more

The commercial implications of PCI


Section: Articles
Ultimately there is no escape from PCI. Whether you are a sophisticated multinational retailer or a small business that accepts card payments – online or offline, it is widely expected that much more rigorous enforcement will be commonplace from 2012.   Technologies and strategies for dealing with PCI are still catching up, although technolog ...   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

How Ethernet First Mile can reduce leased line costs


Section: Articles
Ethernet in the First Mile (EFM), also known as IEEE 802.3ah, is defined as a collection of protocols specified in IEEE 802.3, defining the Ethernet in the access networks, i.e. first or last mile.   The first mile (also called the last mile, the subscriber access network, or the local loop), is the link between the end user and the public network. On a typical LAN setting DSL and cable modems operate at a modest 5-10% of the LAN setup’s total capacity which c ...   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
