Today’s telecom service providers are confronting powerful market drivers that are challenging their network operations and business models. First, a plethora of new technology options are now available to upgrade legacy networks, but this creates interoperability issues between existing and new hardware and software. Second, constant growth in customer demand for bandwidth is challenging service

As more and more traffic is driven into data centers, in turn pressure builds between and among data centers. This phenomenon is known as the “bandwidth amplification effect,” which essentially means that when X amount of user traffic passes into a data center, it generates many times that amount of traffic within the data center

In rural areas, groups of towns are often connected by a telecommunications ring or rings. Schools, municipalities, hospitals and other customers are connected to communications services over these rings. In this type of environment, high school football games are often important community events; video feeds of the games, usually on Friday nights (hence the term

Several technologies, such as Ethernet and WDM, can be utilized in a packet-driven network (PDN). PDNs are a common approach to aggregation and transport of wireless backhaul, business services and in some cases, residential services. Like any product, the secret sauce for a PDN is the feature set. Let’s take a look at the packet-driven

Data Center Interconnect has historically been driven by the pressure of simple demand: the kind of demand that’s satisfied by big, fast, dumb point-to-point pipes. But the value and potential of “big and fast” are held in check by “dumb.” It’s like football; bigger and faster will only take you so far in the National

For the ICT industry, this nascent era of business models based on cloud computing and OTT content is characterized by a heady brew of innovation, change and growth. Open networking offers service providers a route to much-needed rapid service deployment, agile innovation, and leaner spending. For these reasons, the industry is pushing for open-source standards

Data Center Interconnect (DCI) traffic comprises various combinations of 10G and 100G on each service. In a typical application, DWDM is used to maximize the quantity of traffic that can be carried on single fiber. Virtually all available products for this function combine aggregation and transponding into a single platform; they aggregate multiple 10G services

Years ago, alarm monitoring and fault management were difficult across multivendor platforms. These tasks became significantly easier—and ubiquitous—after the introduction of the Simple Network Management Protocol (SNMP) and Management Information Base (MIB-II). Similarly, multivendor network provisioning and equipment management has proved elusive. The reason is the complexity and variability of provisioning and management commands in

Carrier Ethernet is a very successful solution for providing services in a metropolitan area. This technology provides a variety of capabilities including multiple classes of service; fast restoration; standardized services such as E-Line and E-LAN; and bandwidth guarantees. As demand grows in a metro Ethernet network it becomes necessary to accommodate capacity beyond 10G access

Perhaps the most onerous issue facing Ethernet network operators is that of upgrading to higher-bandwidth services. Typically, a network interface device (NID) is deployed at a new customer site in the form of a ring that is shared among several customers. At this point, there is a decision to be made: should the NID be
