Cost eficiency of Opaque Network System, Transient Network System and Translucent network system of Mesh Optical Network System

However, service providers require low cost network to optimize profit. This paper analyzes installation cost of opaque networking system, transparent networking and translucent networking systems as types of optical mesh networks. To examine Optical mesh network types and analyze their installation cost effective factor one needs to base observation on the following basic network service providers concern for a core optical mesh. Cheap network elements that will not cost the operator a lot in procuring and installing or that needs less re-engineering. Non-proprietary constrained network utilities, option of buying from different vendors Scalability with low footing expense Service assurance with capacity and redundancy Fault detection and management beyond installation Transparent network This Optical network sends signal from source to destination in form of light path. The optical information is passed through optical switch and routers from the initial generator to final destination. The wavelength doesn’t undergo optic-electric conversion (O/E), client network element like a router will interface by use of long haul optics to communicate with the wavelength division multiplexer, making it to remain in the same wavelength. Meaning the information remains in optical domain (OOO) and there is no optical-electronic-optical (OEO) conversion, only a small switching fabric is needed to interconnect the wavelength division multiplexers and client element nodes. Remaining in optical domain creates a simple node architecture at its intermediate switch nodes since no electronic switching fabrics is needed to access wave division multiplexers (WDM), this saves cost and space. It employs nodes like directionless / colorless Reconfigurable Optical Add Drop Multiplexers (ROADM) or Optical Cross Connects (OXC). It is also easy to carry out an upgrade of such a network because of insensitivity of data rate change and protocol of light channel. Transparent network can also employ another cost effective architecture switch that may include a single large fabric instead of multiple switch matrices of small port counts but this also contributes negatively on lack of flexibility. However it has draw backs. According to Boullet and Ellinas, “if one is to provide flexibility, such an architecture design would require the use of tunable lasers at the clients and wavelength conversion. Since signal from client remain on the same wavelength when there is no wavelength conversion only a small size switch fabric is needed to interconnect the WDMs and NEs in a node, which translates to switch scalability” (Boullet & Ellinas, p. 5). Inflexibility leads to increased band width and network operational cost. This negates the saving advantage. Transparent networks needs a centralized planning of each link, this is because of disjoint links since no conversion of the wavelength occurs creating a network of n, where n is the number of WDM channels. This builds a network for unrestricted routing and redundancy capacity sharing involving only optical but would lead to increased bandwidth and network cost. On regeneration ...Show more
