Toward the P2P topology mismatch problem, we proposed a novel P2P service re-directing scheme and it is fully described in reference. Furthermore, we have successfully implemented this mechanism in EPON system. Experimental results show that our scheme can effectively reduce core network traffic, and evidently improve clients' downloading rate.
P2P protocol is widely used in many network applications. Recently, p2p traffic reserves a big part of total access bandwidth and may cause serious problems in EPON. In this paper, a new method to identify the p2p traffic based on the flow ID (five-tuple) is presented. We analyze the factors that influence identification accuracy, and then simulate accurate rate of the new method according to the...
This article proposes and implements a survivable Ethernet passive optical network (EPON) system supporting direct communication between optical network units (ONU) without optical line terminal's (OLT) forwarding. An original centralized automatic protection switching (APS) control mechanism is proposed and implemented by FPGA. The actual test results show that our system's protection switching time...
Ethernet-based passive optical network (EPON) is considered as one of the most promising solutions for the next generation broadband access network. Dynamic bandwidth allocation (DBA) is a key factor to fully exploit the potential of EPONs. Furthermore, DBA is needed to support QoS for differentiated service efficiently. A simple DBA scheme called TTSP is proposed in this paper. TTSP specifies two...
