“…The re-ordering problem can be partly compensated by buffering at destinations [11]. Researchers in [12] [13] have found that with bounded buffer, out-of-order packets impact the throughput of CMT. As described in [14], if the number of the out-of-order packets is beyond the buffer limit, the buffer may overflow and packets may be discarded.…”

With the development of multi-interface terminals, a host can connect to the Internet simultaneously by multiple access technologies. Under multi-access technology, a multi-path transmission can obtain high throughput, increased available bandwidth and enhanced reliability. However, the multi-path transmission with multi-access technology also has the problems that the packet re-ordering is unavoidable, and the fast retransmission is unnecessarily requested. Considering the stochastically varying transmission delay, the problems above may eventually result in a degradation of throughput. As a result, in this paper, we focus on the analysis of buffer overflow probability problem which is influenced by the transmission interval. First, we utilize Reinforcement Learning method to estimate the stochastic delay of end-to-end paths. Then, we discuss problems of re-sequencing buffer occupancy distribution and the overflow probability. In this paper, we model the stochastic delay as a continuous random variable, and then, discuss its mean value and variance. Simulation result shows that the re-sequencing buffer overflow probability is influenced by the transmission intervals and the variance of stochastic delay.

“…Since different paths may have different characteristics in terms of bandwidth, loss rate and delay, it is challenging to aggregate bandwidth of different paths. Bandwidth aggregation is exploited at different layers, from the network layer [3] [4], the transport layer [5] [6][7] [8], up to the application layer [9]. As challenges are common for different layer approaches, this paper focuses on investigating the receive buffer (rbuf) size of CMT in the transport layer.…”

“…Researchers in [14] suggests the lower bound of the required rbuf size to be max (packet size). Researchers in [6,12] have found that with bounded rbuf size, out-of-order packets impair the throughput of CMT. Researchers in [8] assume symmetry of two paths delay and sets the Round Trip Time (RTT) ranging from RTT distribution found by [15].…”

Without proper receiving buffer assignment, Concurrent Multipath Transfer (CMT) could result in either not being able to achieve aggregate bandwidth or being a waste of memory resources. This paper analyses buffer requirement for CMT and find that receive buffer requirement is linearly correlated to ratio of round trip time of different path. Based on buffer requirement analysis, this paper proposes PAM, a precise receive buffer size assignment method. The simulation results verified the linear correlation and show that the PAM can effectively aggregate the bandwidth of multipath while making efficient use of memory resource.

Throughput of Concurrent Multipath Transfer varies with different path selection schemes. As the number of path increases, the path selection solution space increases exponentially while receiving buffer efficiency decreases. To solve this problem, we model the throughput of Concurrent Multipath Transfer and find that it may be limited by the receiving buffer size and the round trip time of the slowest path. By analyzing the throughput modeling, this paper proposes a range-based path selection method, which is also validated by the simulation result.
