“…(3) What is the capacity of each token bucket? For question (1), each 1500-byte packet is associated with a token allowing that the Ethernet MTU (Maximum Transmission Unit) is such size [24]. For question (2), the token generation rate should match the available bandwidth of the current computer.…”

Quality of service (QoS) is an important performance indicator for Web applications and bandwidth is a key factor affecting QoS. Current methods use network protocols or ports to schedule bandwidth, which require tedious manual configurations or modifications of the underlying network. Some applications use dynamic ports and the traditional port-based bandwidth control methods cannot deal with them. A new QoS control method based on local bandwidth scheduling is proposed, which can schedule bandwidth at application level in a user-transparent way and it does not require tedious manual configurations. Experimental results indicate that the new method can effectively improve the QoS for applications, and it can be easily integrated into current Web applications without the need to modify the underlying network.

“…Internet adopts a besteffort service model, which lacks the capability of QoS guarantee inherently [1]. Although traditional methods such as Resource Reservation Protocol (RSVP) [2] and Differentiated Service (DiffServ) [3] can improve the QoS for Web applications effectively, they require modifying the underlying network [4].…”

“…These standardizations has laid the foundation of the modern 4G technology, which is a packet switched network based on internet protocol and has data rates up to 1 Gbps [1]. This compliments the general characteristics of VoIP setup of ease of launch of additional services along with the conventional telephony -voice services [2].The integration of different web-based applications in modern VoIP service had led to the various challenges of Quality of service(QoS) faced by the VoIP application. These challenges are [3], the requirement of high bandwidth, sensitivity to propagation delay, sensitivity to jitter, etc.…”

Abstract-With the advent of various web-based applications and the fourth generation (4G) access technology, there has been an exponential growth in the demand of multimedia service delivery along with speech signals in a voice over internet protocol (VoIP) setup. Need is felt to fine-tune the conventional speech codecs deployed to cater to the modern environment. This fine-tuning can be achieved by further compressing the speech signal and to utilize the available bandwidth to deliver other services. This paper presents a scalable -hybrid model of speech codec using ITU-T G.729 and db10 wavelet. The codec addresses the problem of compression of speech signal in VoIP setup. The performance comparison of the codec with the standard codec has been performed by statistical analysis of subjective, objective and quantifiable parameters of quality desirable from the codec deployed in VoIP platforms.
