Lambda Rails Application - Essay Example

Lambda Rail Introduction “Lambda” in Lambda Rails is a term that is used to refer to a wavelength of light (in a wave division multiplexing (WDM) system) which is used to carry digital information/ data over a fiber optic cable to connected communication points. Additionally, that light in a lambda can transfer data at a speed of 10 gigabits per second as enabled by WDM technology. This also means that the fiber optic cable is potentially able to carry hundreds of lambdas. “Rail,” on the other hand, refers to railroads connecting cities and the fact that fiber optic networks that are interlinked can share same paths as the initial railroad links/ lines. Lambda Rails Lambda Rail is a unique and highly rich set of facilities, capabilities and services aimed at supporting sets of numerous distinct, production and experimental network topologies for the US research and extension communities. Lambda Rails Application-Driven Network Deployment Process Importance of WDM This application is able to yield up to 80/160/320 wavelengths from a piece of fiber, or a defined coarse wave division multiplexing (CWDM) gear which is only capable of delivering an output of just a few channels. National Lambda Rails National Lambda Rail is a high-speed, several miles long-national network infrastructural wholly owned and managed by U.S’s educational and research communities running over the fiber-optic lines, and is categorized as the first transcontinental Ethernet network system. It is known for its high capacity, availability and bitrates which enable NLR to offer support to the world’s most involving research projects. National Lambda Rail is fundamentally oriented to assist in large scale computing efforts and to be therein used as a network topology verified for use, experimentation and implementation in the next-generation larger network setups. The most explicit feature of the lambda rails is its capability to uphold both experimental and production network topologies during the same periods. Notably, production network systems are operated over the National Lambda Rails and can be depended upon by their intense users to help achieve their desires for effectiveness, steady availability, reliability and high performance of the network system. The aspect of networks’ efficiencies: i. Enables for broad-based and dependable access of internet/ network functionalities as may be the requirements of researchers to a variety of networks running with National Lambda Rail. ii. Enhances movement of promising technological inventions and innovations from experimental networks to production networks. iii. Provides for real-world data generation networks that facilitates studies. iv. Promotes the initiation, development and doing of research and development activities that exceeds or rather correlates different network layers. v. Augments advanced transition of research out comes between network layers. The table below depicts different sections of the National Lambda Rail layers Layer Network Application Layer 1 Optical networks Layer 2 Switched networks Layer 3 Routed networks Layer 4 End-to-end transport protocols Layers 5-7 Middleware and applications National Lambda Rails potentially provides for operations across and on the highly interrelationships that exist between the traditionally defined network topology layers: switched networks, optical networks, end-to-end transport protocols, middleware and applications and switched networks. Following the commitments of National Lambda Rails, more than half of their resources are to be made available to network research and related experimental activities. Therefore, realization of the below objectives are deemed very necessary in the implementation of National Lambda Rails: Narrowing the gap that existed between leading-edge optical network research the related state-of-the-art applications research. Enabling and rekindling the possibilities for very creative, unique experimentations and innovation exercises that characterize facilities-based online research within the initial stages of internet. To initiatively explore and implement techniques that will see efficiency past the technical and performance limitations of current internet drawbacks. Allowing for expansion on e-Science innovation and invention projects, initiating and experimenting on the highly performing bandwidths, deterministic performance features e.t.c. Considering the development of National Lambda Rails, it is built on a four wavelengths platform of different types with differing functionalities. i. The first bunch of wavelengths is used to provide national footprint switched Ethernet experimental network aimed at providing the initial circuit-like 1 Gbps services and then developing to complex LAN services. ii. The second wavelength is used to supply a national 10 Gbps IP network to provide for internetworking and end-to-end transport protocol experimentations meant to be crucial segments of National Lambda Rails’ research objectives. iii. A third wavelength is to serve as faster initiating facility for new research projects in aid of data and computation rigorous technical projects, identified computational grids, telepresence, and other inter related scientific experiments. This particular wavelength additionally provides redundant sparing capabilities in the process of channel-specification limitations. iv. Wavelength four is used to experiment with new techniques and, solely, to provide new services aimed at providing high level network performance to profound end users. This strategy is objectively meant to be integrated with international effort to foster collaboration with researchers all over the world. Among the services that this NLR is capable of meeting with regards to its varied number of wavelengths include: NLR Frame Net: Ethernet-Based Services Dedicated end-to-end or shared or multi-point transport within multi-megabit, 1- and 10GE data rates for high-volumes of data flows. NLR IP Transit Net: A Complete, Global Internet Transit Solution A fast, efficient and cost-effective Internet services provided by the most advanced networks i.e. in US, NLR, and NLR’s international carries partner TeliaSonera e.t.c., of almost 2TB. NLR Packet Net: IP-Based Services Interlinked routed services, connects educational institutions with each other, and with other networks, such as regional, national and international, IP-based research and education network topologies. NLR Wave Net: Lambda-Based Services End-to-end, dedicated, high-capacity 40GE or 10GE LAN-PHY or OC-192 network connections/ services, enhance users to moderate their point-to-point pathways. NLR Presence: video-based Collaboration The epitomized Cisco TelePresence over NRL generates similar, in-person meeting experiences in the geographically scattered users over the network. Conclusion This network design architecture was developed to provide the best connectivity for research and education. It is constructed based on DWDM optical. It provides high capacity data services at significantly lower charges rates than the known commercial internet providers. Hence, the result is a better network connectivity for advanced research and education network connectivity at lower costs. Besides U.S connectivity as discussed in the above developments, other countries such as Florida, Michigan, Mexico e.t.c., have implemented this networking system to improve and meet their target requirements as far as internet demands are in connection with learning and research institutions.
