Elastic and Inelastic Traffic - Assignment Example

This project is hence aimed at addressing these issues and affirming a corrective architecture to be implemented. 1.1. Objectives Considering the predefined network conditions, the restructuring of the network architecture is aimed at achieving the organization’s strategized objectives of enhanced performance, scalability and agility, increased flexibility to offer support to the various services and devices, high levels of security measures in place, redundancy and higher availability rates, ease of network manageability, lower OPEX and CAPEX, and finally to ensure long term viability of the whole network topology and its interconnected devices. 2. Current functional problems and there proposed solutions As highlighted in the overview, functional problems have been identified and below are discussions of the impact to the organization and consequent corrective measures that need to be taken by the organization to restore its operation to normalcy. 2.1.

Throughput The likely causes of throughput over this network structure under scrutiny may be due to the high number of users (1000 employees) as compared to the type of server installed; the prevailed bottleneck speed; kinds of services being accessed by the staff members; the amount of cache and proxy server usage; efficiency involved in the media access control layer; the type and amount of noise within the transmission lines and errors on the cable plant; and the resultant tweaking of the operating system if any.

Initiatives of this project therefore are to come up with solutions aimed at optimizing throughput, availability and inherent limitations that hinder the protocol performances with corrective measures to these limitations. Besides, WAN Accelerators can be used through its direct installation into the architecture accelerate the transmission speeds. 2.2. Packet loss Packet loss affects throughput for the TCP streams at high-speed i.e. those associated with multi-media and data replication. For improvements on this, Forward Error Correction (FEC) will be used in the new network architecture to effectively mitigate the negative impacts of packet loss to the organization (Teruko M.

, Harumoto F. and Satoshi O., 1999). Additionally, FEC has the effect of introducing overhead which also reduces throughput. Through the use of FEC algorithm that adapts to data loss, the algorithm begins to carry extra packets once it detects packet loss and increases with an increase in the amount of loss (Jean-Chrysotome Bolot., 1993). 3. Architecture The intended network architecture that is designed to replace the current protocol will be the Domain Name Server architecture, which is an internet service that converts domain names in the form of IP address to alphabets for ease of remembrance and classification (Radia P., 1999). The need to shift to this particular type of server was driven by the facts that include DNSs’ improved mechanisms aimed at providing intense network security against attacks; automatic and periodic check of possible errors that may tamper with the network systems’ mode of operations; it is relatively easy to use; its high flexibility in that a single DNS server is capable of managing multiple internet sub-domains and domains within a network structure; it is consistent in its techniques of naming structure for both internal and external
