摘要：We propose a Latency Equalization (LEQ) service, which equalizes the supposed latency for all clients participate in an interactive network application. To successfully apply the proposed LEQ service, network support is necessary. Our networkbased LEQ service provides equalizedlatency paths between the clients and servers by redirecting interactive application traffic from different clients along paths that minimize their delay difference. The LEQ architecture uses a few routers in the network as hubs to transmit packets of interactive applications along paths with similar endtoend delay. We first formulate the hub selection difficulty, prove its NPhardness, and provide a greedy algorithm to solve it. Through extensive simulations, we show that our LEQ architecture extensively reduce delay difference under different optimization criteria that allow or do not allow compromising the peruser endtoend delay. Our LEQ service is incrementally deployable in today’s networks, requiring just software modifications to edge routers.
