Traffic measurement-based admission control using rate envelope in ATM networks

The Loss Rate Analysis of Information Packet in Bi-Directional Cable TV Network

“…If the number of information packets which have reached is larger than the capacity of the buffer, the information packet will produce an overflow, which causes the information packets to be abandoned service, which also means the packets lost. Finite buffer system (S information packets can be stored) information packet loss rate is defined as the ratio of the number of information packets to the total loss of the packet number of the input information [9].…”

Periodic bandwidth allocation based on virtual queue occupancy

“…ITH the explosive growth of Internet users, carrying IP traffic over connection-oriented networks such as ATM has been intensively studied [1][2][3][4][5]. Moreover, the industry [6][7][8] is envisioning the evolution of network structures that combines two technically disparate segments: the optical domain and the electrical domain.…”

“…In the literature, there are three categories of bandwidth allocation strategies [2]: static algorithms keep the original allocation once the allocation is set up; periodic algorithms update the bandwidth at equal time intervals; adaptive algorithms allocate the bandwidth whenever the preset conditions are met. Additionally, traffic monitoring algorithms can be classified into two broad categories: one follows the real time traffic intuitively [2][3]; the other one learns about and predicts the incoming traffic by analyzing statistical data [4][5].…”

“…Scenario 1: a buffer is newly empty at the end of period , which definitely infers a slow arrival rate, thus the bandwidth manager should reduce the bandwidth allocation in the upcoming period. According to (5), when the queue occupancy becomes 0, the allocated bandwidth for period does reduce to (1). Scenario 2: a buffer has been empty for a while, which indicates that the allocated bandwidth has been more than necessary and the bandwidth manager should have reduced bandwidth allocation more aggressively.…”

“…Therefore now the bandwidth manager needs to allocate less bandwidth than that of the scenario 1. According to (5), however, the queue occupancy is 0, and the allocated bandwidth is still the same as (1).…”
