In this paper, we analyze flow-based routing schemes in SDN. Specifically, we study the flow-based routing performance; combining the knowledge of the link condition and updating the period for calculating the path. The framework uses centralized control of SDN where the SDN controller calculates available paths to determine the routing policy based on a global knowledge network. This flow-based routing...
As one of the most popular topics in the Next Generation Network (NGN), Named Data Networking (NDN), a newly proposed network architecture centered on content data, targets on altering the existing communication protocol between Internet hosts. NDN uses data names rather than IP addresses for data transmission and re-designs the packet formats and the protocols between layers in order to substitute...
Efficient delivery of video sequences over best effort networks is challenged by delay variations and packet losses which occur due to congestion at intermediate routers in addition to the stringent quality of service (QoS) requirements of video applications. In this paper, we propose a joint path diversity and priority-based queuing scheme for video streaming over best effort networks like the Internet...
With the development of Internet and the constant emergence of all kinds of multimedia business, user's demand on Quality of Service (QoS) becomes higher and higher. However, the current Internet routing protocol could not provide a good solution for QoS. Quality of service route is at present a very important research topic in the routing protocol, but it is hard to give a perfect method for network...
Today router buffers are sized according to the well-known Bandwidth-Delay Product (BDP) rule, which uses the average round-trip time (RTT) of flows traversing a router. The BDP rule not only leads to large queueing delays, but also imposes “one (buffer) size fits all” philosophy for flows exhibiting a large variation in RTT. When short and long RTT flows compete at a single buffer, they may adversely...
In this paper, we propose a new intersection-based geographical routing protocol, called delay tolerant routing protocol (DTRP) that adapts to the changes in the local topology within city environments. DTRP is based on an effective selection of road intersections through which a packet must pass to reach the gateway to the Internet. The selection, in such delay tolerant VANETs, is made in a way that...
