Frequently Asked Questions About Network Management
Virgin Mobile is committed to providing the best mobile broadband Internet access service experience possible for its customers. To ensure that all customers enjoy the best possible network experience, Sprint uses reasonable network management practices that are consistent with mobile broadband industry standards and guidance provided by the Federal Communications Commission (FCC). Sprint's network management practices are primarily used for and tailored to achieving legitimate network management purposes taking into account Sprint's network architecture and technology.
The following Frequently Asked Questions are intended to help clarify for Virgin Mobile customers what we mean by network management and explain Sprint's network management techniques and approaches.
Why does Sprint manage its network?
Sprint manages its network with the goal of delivering the best possible mobile broadband Internet access experience to all of its retail customers. Mobile network resources are not infinite. Managing the network is essential to promote the use and enjoyment of mobile data by all network users. Sprint uses reasonable network management practices that are consistent with industry standards for protecting Sprint's network and customers and for managing the delivery of mobile broadband services. Just as the Internet continues to change and evolve, so too, will Sprint's network management practices to address the challenges and threats on the Internet.
If Sprint didn't manage its network, network users would be subject to the negative effects of spam, viruses, security attacks, network congestion, and other risks and degradations of the service. By engaging in reasonable and responsible network management, Sprint can deliver the best possible mobile broadband Internet access experience to all users of the network.
How does Sprint manage its network?
Sprint uses various tools and techniques to manage its network and deliver its services. These tools and techniques are dynamic, like the Sprint network and its usage, and Sprint may update the tools and techniques it uses. Sprint's network management activities include managing congestion and allocating resources among users on the network, optimizing certain content and applications, identifying spam and preventing its delivery to customers, detecting malicious Internet traffic and preventing the distribution of viruses or other harmful code or content, and using other tools and techniques that Sprint may be required to implement in order to meet its goal of allowing Virgin Mobile to deliver the best possible broadband Internet experience to all of its customers.
How does Sprint manage congestion on the network?
Sprint employs a holistic approach to managing congestion on its data network. Sprint's first goal is to avoid congestion altogether by directing traffic to the best available spectrum resources and cell sites. Sprint also attempts to avoid congestion by managing tonnage on its network. Finally, when congestion does occur, meaning that the demand on a particular sector temporarily exceeds the ability of that sector to meet the demand, Sprint relies on the radio scheduling software provided by Sprint's hardware vendors to allocate resources to users.
Techniques to Direct Traffic to the Best Available Spectrum Resources and Cell Sites: All mobile networks, including Sprint's, employ a Radio Access Network ("RAN") that manages connectivity between mobile client devices and the core network. The RAN functions to identify mobile devices permitted to access the network and their locations and assigns the mobile device to an available frequency band and cell site serving the location. The RAN also controls device "hand off" between neighboring cell site resources to balance load across network resources or as a mobile device moves from one location to another. Sprint's RAN manages connections between mobile devices and cell sites operating on multiple frequency bands (800 MHz, 1.9 GHz, 2.5 GHz) and multiple air interfaces (CDMA, EVDO, LTE). As part of managing those connections, Sprint's RAN is designed to dynamically connect customers to the best available spectrum resources and cell sites-and reassign those connections as circumstances change.
Managing Tonnage: The majority of Sprint's traffic management efforts are aimed at avoiding congestion by managing the total volume of data transmitted, referred to colloquially as "tonnage." Sprint manages tonnage by optimizing certain applications on the network such as video and web traffic. This optimization improves page load times and reduces video stalling, while also eliminating wasted data transmissions that result from lack of coordination between applications, the network, and a device (for example, stopping transmission of a video after a customer has stopped viewing it). It also matches media transmission quality to the capability of the device viewing the media.
Allocating Resources During Times of Congestion: Despite its best efforts to prevent congestion through managing tonnage and directing customers to the best available network resources, the demand on a particular network sector sometimes temporarily exceeds the ability of that sector to meet the demand. During these times, Sprint relies on the radio scheduling software provided by Sprint's hardware vendors to allocate resources to users. This radio scheduling software includes a set of generic fairness algorithms that allocate resources based on signal quality, number of users, and other metrics. These algorithms are active at all times, whether or not the cell is congested; however, during times of congestion, the algorithms operate with the goal of ensuring that no single user is deprived of access to the network.
Quality of Service (QoS): To help protect against the possibility that unlimited data plan customers that use high volumes of data may occupy an unreasonable share of network resources, Sprint employs network prioritization or QoS on the Sprint network. Customers who choose unlimited data handset plans launched on or after October 16, 2015, or customers who choose to upgrade their handsets on or after October 16, 2015, and are on unlimited data plans, that use more than 23GB (to be adjusted periodically) of data during a plan cycle will be de-prioritized for the remainder of that plan cycle as compared to other customers at times and places where the availability of network resources is constrained. Affected unlimited data customers will continue to be able to enjoy unlimited amounts of data without the worry of overage charges or hard, full bandwidth reductions. Customers subject to prioritization may experience reduced throughput and increased latency compared to other customers on the constrained site and as compared to their normal experience on the Sprint network. Unlimited customers may also notice temporary changes in the performance of data intensive applications such as streaming video or online gaming when subject to prioritization. These temporary reductions in performance will only occur at times and places where capacity is constrained. Performance will return to normal as soon as the resource constraints have been relieved or the customer has relocated to a non-constrained location. Unlimited data customers potentially subject to lower QoS will be notified when their individual data usage reaches approximately 75% of 23 GB so that they may modify their usage to avoid network management practices that may result in slower data speeds. We will notify customers when they have reached the 23 GB threshold and become subject to de-prioritization.
Real-Time Traffic Management System (RTTMS): Another tool Sprint has deployed to help improve the customer experience for the majority of customers during times and places where network resources are constrained is Sprint's RTTMS. When a Sprint site is resource constrained, RTTMS works to identify the users consuming the most site resources, and reallocates a portion of the resources serving the data intensive users to other users engaged in less resource intensive activities. When RTTMS is activated on a resource constrained site, customers engaged in data intensive applications may experience reduced performance until the site becomes unconstrained or the user moves to a non-resource constrained site. Users of the resource-constrained site that are not engaged in data intensive activities should expect a better experience than they would have on the site if RTTMS not activated. Sprint's RTTMS is user, content, application, and device agnostic and is intended to provide an improved experience for the majority of users when resources are constrained.
How does congestion management impact me and my data services?
The goal of congestion management is to ensure that all users during times of congestion have access to a fair share of the network resources and that no user is starved of resources. When congestion occasionally occurs, customers may experience reduced throughput or speed compared to their normal experience on non-congested sites.
How often does Sprint use congestion management?
Because of the peaked nature of mobile data traffic, congestion management software is actively looking for network congestion at all times. When it detects congestion, the fairness algorithms described above operate with the goal of ensuring that all customers are allocated a fair share of network resources.
To help reduce congestion, Sprint evaluates its overall network performance and enhances its network by adding capacity or making other network adjustments to help improve network performance.
Does Sprint employ any type of data compression or optimization on the Sprint network today?
Yes, Sprint deploys network optimization capabilities for video and web traffic, with the intent to improve overall user experience and increase network efficiency. Optimization helps improve page load times and reduces video stalling. The optimization technology provides for the elimination of wasted data transmission that results from lack of coordination between applications, network, and device, for example stopping transmission of video after a customer has stopped viewing it. It also matches media transmission quality to the capability of the device viewing the media.
What specific types of optimization does Sprint employ?
Video optimization is deployed for RTSP and HTTP video traffic and all HTTP web traffic. Video optimization is always deployed and active on the Sprint network for all identifiable video traffic. Although the purpose of the optimization techniques is to improve overall video viewing experience, it is possible that some users may experience minor discernable reductions in image quality when viewing video traffic on certain devices. These reductions should generally be offset by improvements in load times and reductions in video stalling and other experience improvements. Sprint's video optimization uses four basic technologies:
- Video Delivery Synchronization:
- Delivers video "just in time" to the mobile device. Intent is to eliminate network waste associated with transmitting video that isn't watched.
- Quality Aware Transcoding:
- Matches video quality with network conditions in real time. Optimizes video for the bandwidth available to the user. Intent is to minimize or eliminate annoying video stalling. Similar in concept to the optimization techniques already employed by sites using adaptive streaming.
- Video Transcoding:
- Transcodes video with intent to optimize the video experience for the user while efficiently using network bandwidth. Provides for the elimination of video waste using techniques like replacing less efficient video codecs with more efficient ones. Optimizes video for the mobile device the customer is using.
- Intelligent Caching:
- Caches optimized video in the network with the intent of eliminating delay associated with internet video sites.
Note that some customer may choose plans that include throughput limits for streaming video applications. Refer to your specific plan materials for information on video streaming policies relating to your plan.
What specific types of web optimization does Sprint employ?
Web optimization is deployed for all HTTP web traffic and is always deployed and active on the Sprint network for all identifiable web traffic. Although the purpose of the optimization techniques is to improve overall web viewing experience, it is possible that some users may experience minor discernable reductions in image quality when viewing web traffic on certain devices. These reductions should generally be offset by improvement s in load times and other experience improvements. Web optimization uses three basic technologies:
- Caching: Caches web pages to help avoid delays associated with retrieval of the same internet content multiple times.
- Text/Binary Compression: Lossless compression of data and binary files using standard compression techniques supported by HTTP-compliant browsers.
- Image Compression: JPEG and GIF compression designed to reduce the size of images while maintaining no user perceptible loss of quality.
