“…According to the required Quality of Service (QoS), multimedia services are commonly classified into two classes, which are class 1 (real-time or inelastic) traffic services and class 2 (non-real-time or elastic) traffic services [5]. Different classes of services over networks not only require different amounts of bandwidth but also demand different QoS requirements.…”

To provide a comprehensive network access service to wireless users, a network operator may operate different types of wireless networks (such as GPRS, Wi-Fi, HSDPA, UMTS, WiMAX and 3GPP LTE) simultaneously to become a heterogeneous wireless network operator, such as Vodafone and T-Mobile. With convenience of accessing wireless networks, ubiquitous services would stimulate the bandwidth expenditure in the network backbone. Lots of various demanded traffic from heterogeneous access networks may converge toward Internet through the common backbone in the operator. Efficiently utilizing the common backbone can offer a better quality of service to users and maximize the revenues for the operator. To our best knowledge, few studies had ever been made in such a contemporary wireless network environment in the past. In this study, we propose solutions to efficiently allocate the bandwidth for user requests and fully utilize the unused bandwidth in the network backbone owned by the heterogeneous wireless network operator. Our simulation results show that our scheme can increase the utilization of the backbone bandwidth, shorten the request completion time for users and generate more revenue for the operator.

“…Bandwidth management is a set of activities, which are undertaken by organizations which have obtained bandwidth, to ensure the efficacy and control of their communication lines. Online videos being a relevant multimedia source in any learning environment is crucial and requires a little more bandwidth for their viewing than regular text (Kim and Varshney, 2005; Ying and Basu, 2005). As such, there is a need for plans and policies to be put in place in our information networks to cater for this.…”

Online video streaming is a learning technology used in today’s world and reliant on the availability of bandwidth. This research study sought to understand the perceptions of network gatekeepers about bandwidth and online video streams in Ahmadu Bello University, Nigeria. To achieve this, the interpretive paradigm and the Network Gatekeeping Theory were used as the theoretical framework and also a case study approach was employed to investigate the phenomenon. The study used a purposive sampling technique and a semi-structured interview to seek out opinions from the respondents who were the network gatekeepers within the university. A thematic analytical approach was done with the use of NVivo software, which yielded one hundred and seven codes, ten sub-categories and four major categories. The findings from the study indicated that: (1) perceptions of network managers were one sided; (2) no acceptable user policy was on ground and available bandwidth was limited; and (3) limitation of bandwidth, hindered user access to online video and mechanisms for gatekeeping had a role to play in the overall access to online video.
