Effective Voice Frame Shrinking Method to Enhance VoIP Bandwidth Exploitation

The demand for the telecommunication services, such as IP telephony, has increased dramatically during the COVID-19 pandemic lockdown. IP telephony should be enhanced to provide the expected quality. One of the issues that should be investigated in IP telephony is bandwidth utilization. IP telephony produces very small speech samples attached to a large packet header. The header of the IP telephony consumes a considerable share of the bandwidth allotted to the IP telephony. This wastes the network's bandwidth and influences the IP telephony quality. This paper proposes a mechanism (called Smallerize) that reduces the bandwidth consumed by both the speech sample and the header. This is achieved by assembling numerous IP telephony packets in one header and use the header's fields to carry the speech sample. Several metrics have been used to measure the achievement Smallerize mechanism. The number of calls has been increased by 245.1% compared to the typical mechanism. The bandwidth saving has also reached 68% with the G.28 codec. Therefore, Smallerize is a possible mechanism to enhance bandwidth utilization of the IP telephony.

“…The embrace of VoIP technology is exponentially expanding due to different favorable benefits, one of which is the exceptionally modest rate, which is considered the main benefit (Abualhaj et al, 2016;Affonso et al,2018). Despite that, bandwidth (BW) exploitation and quality are two key concerns that make trouble for VoIP technology's embrace (Olariu et al, 2016;Shambour et al;. This research interest is the BW exploitation of VoIP technology.…”

“…The preamble compression methodology has effectively compacted the 40 octet RUI VoIP packet preamble to just 2 octets. Thus, the preamble compression methodology profoundly decreases preamble overhead, also enhancing BW utilization (Shambour et al, 2020;Hussein et al, 2020;Seytnazarov et al, 2018;Maqhat et al, 2014). Aside from these two methodologies, a novel protocol, named Internet Telephony Transport Protocol (ITTP), has been created to convey IP voice calls (Abualhaj et al, 2019b;Abu-Alhaj et al, 2012).…”

Voice over IP (VoIP) is widely utilized by organizations, schools, colleges, and so on. Nevertheless, VoIP numerous challenges that hinder its spread. One of the significant challenges is the poor exploit of the VoIP technology network bandwidth (BW), caused by the huge preamble of the VoIP packet. This paper suggests a novel methodology to manage this huge preamble overhead challenge. The proposed methodology is named runt payload VoIP packet (RPV). The core principle of the RPV methodology is to reemploy and exploit the VoIP packet preamble’s data (fields) that are superfluous by VoIP technology, especially for unicast IP voice calls. Generally, those fields will be used to convey the VoIP packet payload. Consequently, diminish or zero the length of the payload and, therefore, spare the BW. The results of the investigation into the suggested RPV methodology indicated significant enhancement in the BW exploitation of VoIP technology. For instance, the saved BW in the examined environment with the LPC codec came to up to 25.9%.

“…Second, the packet aggregation approach works by collecting packets to the same addressee and merging them in a header in place of a header to every packet. The more the merged packets are, the higher the preserved bandwidth is (Hussein et al, 2020;Shambour et al, 2020;Seytnazarov and Kim, 2018). Figure 1 presents the packet aggregation approach.…”

Old telecommunication systems are gradually being replaced by a new system that works over IP networks, which is known as voice over internet protocol (VoIP). VoIP has several merits (e.g., very cheap call rate), which make it increasingly popular in the telecommunication world. However, VoIP faces numerous impediments that decelerate its promotion. One of the top impediments is the wasted bandwidth caused by VoIP systems. Numerous methods have been proposed to handle this impediment, including packet aggregation methods. This paper proposes a novel aggregation method, called packet aggregation and carrier header (PA-CH), to reduce the amount of the large bandwidth caused by VoIP. As the name suggests, PA-CH saves in bandwidth by aggregating the packets in a header and using the redundant fields in the packet header to carry a portion of the packet voice data. The performance of the introduced PA-CH method was investigated based on three main metrics, namely, link capacity, allocated bandwidth reduction, and voice data shortening. Simulation results indicate that the proposed PA-CH method outperforms the comparison methods in three factors. For instance, the proposed method’s allocated bandwidth reduction ratio reaches 51% when the number of calls running concurrently reaches 100. Therefore, the proposed PA-CH method achieves its goal of reducing the wasted bandwidth caused by VoIP.
