A novel passive optical node with low latency for optical access network (OAN) is proposed, in which the optical circuit just consists of several optical splitters. 1310nm/ 1490nm wavelength division is used in the node. At 1310nm wavelength, any optical network unit (ONU) in one group can transmit the uplink signal to OLT and any ONU in the other group. This realizes communication between two ONUs...
This paper presents a distributed lookup protocol named Automatic Balancing Chord(ABC) to solve load imbalance problems in distributed system. Load balancing problems in P2P environment have an important impact on the performance of P2P applications, which are probably caused by allocation of the peer address space, the difference of load size, query uneven distribution and so on. This paper proposes...
Most current approaches have been explored to improve Chord lookup efficiency. However, the problem that confronts every node is to increase the routing table size to maintain too much state information of other nodes. In this paper, we propose a regional lookup algorithm based on super-node that routes data keys queries by region information and super-node. The lookup process can be easily implemented...
In this paper, we present an effective approach for live media streaming based on BitTorrent mechanism. In the approach, several modifications have been incorporated into BitTorrent to support on-time content delivery. First, pieces are selected based on their scheduler play back deadline. Second, source behaves in a push-based way instead of pull-based way. Finally, each peer periodically examines...
