Quality of Service (QoS). Defined as a way to prioritize service for applications that are sensitive to latencies or delays. It is the primary form of intelligent bandwidth management that allows service levels to be specified for different traffic types.
Quality of Service (QoS). QoS is the ability to provide different priority to different applications, users, or data flows, or to offer a certain level of performance for data flows. For example, a required bit rate, latency, jitter, packet loss probability and/or bit error rate may be offered by Windstream to Customer. To determine what QoS level applies to a Service, Customer either must select from the following QoS classes of service or subscribe to a Service that is defaulted into one or more QoS classes. The Windstream QoS classes are identified as: Current QoS Service Level Name Former QoS Service Level Name Description Expedited Forwarding Real Time This class of service delivers premium QoS to a customer's location and is optimized for low latency and low jitter performance required for voice communications. All managed VoIP services are defaulted into Expedited Forwarding QoS. The traffic in this queue can NOT exceed the percentage assigned to this queue (even if bandwidth is available from other queues). Assured Forwarding 4 N/A This class of service provides the highest priority treatment for data. Intended for applications with high business value requiring large bandwidth allocations and/or lower latency such as interactive video conferencing, streaming video. The traffic in this queue can exceed the percentage assigned to this queue if bandwidth is available from other queues. Traffic exceeding the assigned percentage is given the class’s expected treatment if bandwidth is available from other queues. Assured Forwarding 3 Mission Critical Data This class of service provides the next highest priority treatment for data. Intended for applications with high business value requiring large bandwidth allocations such as credit card transactions, and ERP applications like SAP and PeopleSoft. The traffic in this queue can exceed the percentage assigned to this queue if bandwidth is available from other queues. Traffic exceeding the assigned percentage is given the class’s expected treatment if bandwidth is available from other queues. Assured Forwarding 2 N/A This class of service is typically applied to transactional and low latency data such as email. The traffic in this queue can exceed the percentage assigned to this queue if bandwidth is available from other queues. Traffic exceeding the assigned percentage is given the class’s expected treatment if bandwidth is available from other queues. Assured Forwarding 1 Business Critical Data This class of service is typically a...
Quality of Service (QoS) is evaluated on the basis of observable measure on the grade of service or the response time and also includes acceptable grade of number of faults per unit population of the subscriber served, the mean time to restore (MTTR), faults carried over beyond the MTTR and the satisfactory disposal thereof, as prescribed by TRAI vide Notification entitled ‘Quality of Service of Broadband Service Regulations 2006 (11 of 2006) No. 304-6/2004 QoS dated 6th October, 2006, as amended or replaced from time to time, if any.
Quality of Service (QoS) reporting
1. Scope
Quality of Service (QoS) a) ICS-‐ACI will be maintained as a highly available resource to Users, with predicted downtimes as scheduled in d) and e) below.
b) ICS-‐ACI reserves the right to shut down any or all of its systems for unscheduled maintenance/upgrades when necessary. ICS-‐ACI will only exercise this option in extreme circumstances. Examples of such circumstances include:
i. Unplanned system outages due to facility issues, including, but not limited to, power, HVAC, external-‐system network;
ii. Emergency maintenance on systems and facilities;
iii. System downtime to address computer security incidents.
c) ICS-‐ACI will provide as much advance notice as possible related to system outages. ICS-‐ACI will always make a best effort to meet the T&C except in cases of Force Majeure.
d) ICS-‐ACI will conduct planned shutdowns of systems for maintenance/upgrades, providing a minimum of two (2) weeks’ notice, as follows:
i. July and January -‐ 60 hours ii. March and November – 36 hours iii. May and September – 12 hours
e) ICS-‐ACI will apply system software patches on Tuesdays from 5am to 8am as necessary. Also, ICS-‐ACI may apply security patches, as necessary, at any time. Components of ICS-‐ACI may be unavailable during these periods.
f) ICS-‐ACI will announce full and partial, planned and unplanned outages by posting to the ICS-‐ ACI message of the day (MOTD) and e-‐mailing to the ICS-‐ACI-‐Alerts list-‐serve.
g) In the event of an immediate unplanned outage where no prior notice could be given, ICS-‐ ACI will provide a post-‐outage announcement regarding details as to the cause and effects of the outage.
Quality of Service (QoS). QoS prioritizes assigned traffic types (“Classes”) from the INAP provided router or Customer’s premise equipment through INAP’s backbone network until such traffic is either handed off to an upstream network or terminated. INAP’s Class prioritization utilizes Class Based Weighted Fair Queuing. QoS offers enhanced service metrics.
Quality of Service (QoS). As related to data transmission a measurement of latency, packet loss and jitter. Queuing Queuing is an automated process by which call are presented in a predefined sequence to a call taker. Radio Frequency (RF) Self explanatory. Rate Center A geographically specified area used for determining mileage and/or usage dependent rates in the Public Switched Telephone Network. Real-Time The availability of information at the exact time it is occurring.
Quality of Service (QoS). Quality of service is the ability to provide better service to end users, in the case of IP telephony is the quality of the voice network it provides end users. Prioritize traffic according to their needs, about the different technologies optimizing network resources. By the nature of real-time data such as voice, video, are sensitive to delay, packet loss, change in delays (jitter), should be applied quality of service, which directly relates the size of queues congestion network and switching speed and bandwidth links. There are three models (QoS) quality of service which are: protocol is scalability as it has to maintain state information in each router.
Quality of Service (QoS). QoS is the ability to provide different priority to different applications, users, or data flows, or to offer a certain level of performance for data flows. For example, a required bit rate, latency, jitter, packet loss probability and/or bit error rate may be offered by Windstream to Customer. To determine what QoS level applies to a Service, Customer either must select from the following QoS classes of service or subscribe to a Service that is defaulted into one or more QoS classes. The Windstream QoS classes are identified as: QoS Class of Service Description Real Time Real-time class of service delivers premium QoS to a Customer’s site and is optimized for low latency and low jitter performance required for voice communications. All managed VoIP services are defaulted into real-time QoS. Mission Critical Data Mission critical class of service provides the highest priority treatment for data. Intended for applications with high business value, requiring large bandwidth allocations and/or lower latency such as interactive video conferencing, streaming video, credit card transactions, and ERP applications like SAP and PeopleSoft. Business Critical Data Business critical data class of service provides priority treatment to transactional and interactive data such as email, or client/server applications Standard Data Standard data class of service enables customers to share latency and jitter tolerant data and Internet applications across all locations. Internet Service traffic is defaulted into standard data QoS.
Quality of Service (QoS). Support. Verizon will route Customer traffic based on the priority assigned by Customer using different classes of service designations, which follow the Diff-Serv model. If Customer does not set different classes, Verizon will route all Customer traffic using the Best Efforts (BE) class as the default priority designation.
