Comparing to Availability-Based Provisioning Sample Clauses

Comparing to Availability-Based Provisioning. We first compare our SLA-based provisioning algorithm to the availability-based approach. Figure 3 shows the admittance rate for each algorithm. For low load (10-30 Erlangs), our SLA-based algorithm admits approximately 1.5 times as many requests as the availability-based approach. Similarly, Figure 4 shows that our algorithm satisfies at least 1.5 times as many requests as the competing algorithm. Figure 5 shows that though our algorithm admits significantly more requests than the competing algorithm, it is still able to satisfy a higher percentage of the availability requirements of the requests that it admits. The expected profits acquired by each algorithm are shown in Figure 6. Our algorithm achieves significantly more profit than the previous algorithm (more than twice as much 2Load, measured in Erlangs, is defined as the product of the connection arrival rate, the average connection-holding time, and a connection’s average bandwidth normalized to units of OC-192. to accommodate as many customers as possible, at the risk of violating several SLAs, may choose this policy. In the Admit-Most scheme, requests that are likely to be profitable are admitted and less profitable requests are rejected. An SP whose goal is to accommodate many customers while achieving high customer satisfaction by providing typically reliable service, may choose this moderately aggressive ad- mission policy. Admit-Most is the approach we took for our simulation results in Section V-A. ***Revised (threshold values)*** For our simulations, we used a fixed threshold value and admitted the requests that yielded a profit higher than this threshold. A useful feature of our approach is that SP’s can tune this threshold according to their preferences. Finally, in the Admit-Few scheme, a request is admitted only if its satisfaction probability is higher than a predefined threshold (as in the Admit-Most scheme, SP’s can tune this threshold value). An SP whose goal is to always provide highly reliable service may choose this policy. ***Revised added*** The choice for the admission control scheme may also depend on the urgency levels of requests. For example, SPs who service hospitals or other medical institutions may choose the Admit-Few scheme to ensure that all of their connections will be very reliable. On the other hand, SPs who provide less urgent services may find that the more flexible Admit-All or Admit-Most scheme is a better fit for their needs. Figures 7-8 show that the Admit-F...

  • System Availability System Availability percentage is calculated as follows:  Total MinutesintheMonth −Downtime   System Availability%age =  Total MinutesintheMonth *100    System Availability SLA (“SLA”) 99.5% System Availability percentage during each Month for productive versions Credit 2% of Monthly Subscription Fees for each 1% below SLA, not to exceed 100% of Monthly Subscription Fees Excluded Downtime Total Minutes in the Month attributable to: (i) a Scheduled Downtime for which a Regular Maintenance Window is described in Section 4 below, or (ii) any other Scheduled Downtime according to Section 4 for which the customer has been notified at least five (5) business days prior to such Scheduled Downtime or (iii) unavailability caused by factors outside of SAP’s reasonable control, such as unpredictable and unforeseeable events that could not have been avoided even if reasonable care had been exercised. Scheduled Downtime Scheduled Downtime for the applicable Cloud Services to which customer has subscribed is set forth in Section 4 below entitled “Maintenance Windows for Cloud Services”.

  • Service Availability You understand that Service availability is at all times conditioned upon the corresponding operation and availability of the communication systems used in communicating your instructions and requests to the Credit Union. We will not be liable or have any responsibility of any kind for any loss or damage thereby incurred by you in the event of any failure or interruption of such communication systems or services resulting from the act or omission of any third party, or from any other cause not reasonably within the control of the Credit Union.

  • EPP service availability Refers to the ability of the TLD EPP servers as a group, to respond to commands from the Registry accredited Registrars, who already have credentials to the servers. The response shall include appropriate data from the Registry System. An EPP command with “EPP command RTT” 5 times higher than the corresponding SLR will be considered as unanswered. If 51% or more of the EPP testing probes see the EPP service as unavailable during a given time, the EPP service will be considered unavailable.

  • Mileage Measurement Where required, the mileage measurement for LIS rate elements is determined in the same manner as the mileage measurement for V&H methodology as outlined in NECA Tariff No. 4.

  • DNS service availability Refers to the ability of the group of listed-­‐as-­‐authoritative name servers of a particular domain name (e.g., a TLD), to answer DNS queries from DNS probes. For the service to be considered available at a particular moment, at least, two of the delegated name servers registered in the DNS must have successful results from “DNS tests” to each of their public-­‐DNS registered “IP addresses” to which the name server resolves. If 51% or more of the DNS testing probes see the service as unavailable during a given time, the DNS service will be considered unavailable.

  • Measurement and Monitoring Tools Contractor shall implement measurement and monitoring tools and procedures reasonably designed to measure its performance of the Services and assess such performance against any applicable service levels. Contractor shall provide LAUSD with a monthly report of service level performance under any applicable Work Order. Upon LAUSD’s request, Contractor shall provide LAUSD with access to the measurement and monitoring tools described herein, and to any information that they generate.

  • JOC - PRICING OF After Hours Coefficient What is your after hours coefficient for the RS Means Price Book for work performed after normal working hours? (FAILURE TO RESPOND PROHIBITS PART 2 JOC EVALUATION) Remember that this is a ceiling price proposed. You can discount to any TIPS Member customer a lower coefficient than your proposed contract coefficient, but not higher. This is one of three pricing questions that are required for consideration for award on this solicitation. Please consider your answer carefully. An explanation of the TIPS scoring of pricing titled "Pricing Coefficient Instruction" is included in the attachments for your information. The below is an EXAMPLE of how the pricing model works (It is not intended to influence your proposed coefficient, you should propose a coefficient that you determine is reasonable for your business for the life of the contract): The most common after hours coefficient is time and a half of the RS Means Unit Price Book prices. To illustrate this coefficient, if your regular hours coefficient is .95, your after hours coefficient would be 1.45.

  • Service Levels Annex 1 to this Part A of this Call Off Schedule sets out the Service Levels the performance of which the Parties have agreed to measure. The Supplier shall monitor its performance of this Call Off Contract by reference to the relevant performance criteria for achieving the Service Levels shown in Annex 1 to this Part A of this Call Off Schedule (the Service Level Performance Criteria) and shall send the Customer a Performance Monitoring Report detailing the level of service which was achieved in accordance with the provisions of Part B (Performance Monitoring) of this Call Off Schedule. The Supplier shall, at all times, provide the Services in such a manner that the Service Levels Performance Measures are achieved. If the level of performance of the Supplier of any element of the provision by it of the Services during the Call Off Contract Period: is likely to or fails to meet any Service Level Performance Measure or is likely to cause or causes a Critical Service Failure to occur, the Supplier shall immediately notify the Customer in writing and the Customer, in its absolute discretion and without prejudice to any other of its rights howsoever arising including under Clause 12 of this Call Off Contract (Service Levels and Service Credits), may: require the Supplier to immediately take all remedial action that is reasonable to mitigate the impact on the Customer and to rectify or prevent a Service Level Failure or Critical Service Level Failure from taking place or recurring; and if the action taken under paragraph (a) above has not already prevented or remedied the Service Level Failure or Critical Service Level Failure, the Customer shall be entitled to instruct the Supplier to comply with the Rectification Plan Process; or if a Service Level Failure has occurred, deduct from the Call Off Contract Charges the applicable Service Level Credits payable by the Supplier to the Customer in accordance with the calculation formula set out in Annex 1 of this Part A of this Call Off Schedule; or if a Critical Service Level Failure has occurred, exercise its right to Compensation for Critical Service Level Failure in accordance with Clause 13 of this Call Off Contract (Critical Service Level Failure) (including subject, for the avoidance of doubt, the proviso in Clause 13.1.2 of this Call Off Contract in relation to Material Breach). Approval and implementation by the Customer of any Rectification Plan shall not relieve the Supplier of any continuing responsibility to achieve the Service Levels, or remedy any failure to do so, and no estoppels or waiver shall arise from any such Approval and/or implementation by the Customer.
