Deflection routing is a routing strategy for networks based on packet switching which can reduce the need of buffering packets. Every packet has preferred outputs along which it wants to leave the router, and when possible, a packet is sent along one of these outputs. However, two or more packets may want to leave along the same output (which is referred to as a contention among packets), and then only one of the packets may be sent along the link, while the others are sent along available outputs, even though the other links are not preferred by the packets (because, for instance, those links do not yield shortest paths).

dbo:abstract
  • Deflection routing is a routing strategy for networks based on packet switching which can reduce the need of buffering packets. Every packet has preferred outputs along which it wants to leave the router, and when possible, a packet is sent along one of these outputs. However, two or more packets may want to leave along the same output (which is referred to as a contention among packets), and then only one of the packets may be sent along the link, while the others are sent along available outputs, even though the other links are not preferred by the packets (because, for instance, those links do not yield shortest paths). Depending on the rate of incoming packets and the capacity of the outgoing links, deflection routing can work without any packet buffering. Of course, it is always possible to simply drop packets in a network with a best-effort delivery strategy. (en)
  • 偏向路由 是一個供基於封包交換的網絡使用的路由策略,以減少使用緩衝數據包。每個數據包都有自己的首選輸出口離開路由,將資料送達目標。但是,若同時有兩個或以上數據包於同一個輸出口離開,只有其中一個數據包會經鏈路離開,其餘的只好在其他輸出口離開,儘管這些輸出口並非其首選。 偏向路由在一些情況下並不需要數據包來運作。 (zh)
