knowledge centres’, it is turning progressively vital to produce the network performance guarantees to individual tenants. Owing to the impact of network congestion on the performance of many common cloud applications, recent work has centered on facultative network reservation for individual tenants. Currently, Network Satisfaction Ratio (NSR) mechanism is used for network reservation in cloud data centers.NSR is defined as ratio of actual reserved bandwidth to the desired bandwidth of the tenant. Since NSR, network reservation mechanism admit only time-varying tenant requests and might fairly distribute any degradation within the NSR among the tenants and in the presence of network oversubscription the ratio is very low. In this work, a new mechanism called ENHANCED NSR is introduced where this network satisfaction mechanism admits not only time but also other network performance indicators as computation, storage and memory resource allocation. Due to this inclusion, the satisfaction ratio is increased and the tenant is reserved of its desired bandwidth even during oversubscription in cloud data centers. Hence by increasing the NSR the bandwidth is reserved for the tenant as desired.
