Segment routing (SR) is a new network paradigm to optimize network performance. Through leveraging source routing, SR is able to achieve more fine-grained control of data flow in the SR domain. However, it is difficult to introduce large-scale full SR network into existing traditional network due to the economic constraints and immature operation technology. Thus, incrementally deploying SR nodes into an existing network is preferred, which forms the hybrid IP/SR scenario. In the hybrid network, with SR enabled devices, the routing path of flow can be dynamically adjusted. Network utility is an important factor to reflect the user's satisfaction with the allocated bandwidth. In this paper, we propose a bandwidth allocation algorithm to maximize network utility in hybrid IP/SR network and thus improve customer's satisfaction. The simulation results show that the bandwidth allocation algorithm proposed is able to improve the utility of network significantly, and the utility of network will increase with the number of SR nodes deployed in the network.

Throughout the history of Modern Chinese Literature, Eileen Chang is a prominent female. In the 1940s, she observed the cultural form of Shanghai as an urban woman, depicting the daily life and humanity during the city's prosperity and desolation. Shanghai's urban culture provides a constant source of nourishment for Eileen Chang's novels, and Eileen Chang also uses her unique aesthetic perspective to interpret Shanghai. This article takes a text analysis approach from the field of Shanghai's urban public space to analyze the impact of Shanghai's urbanization development on Eileen Chang's own conceptions, selecting cinemas, dance halls, and other consumer places as research objects. It investigates the urban life of Shanghai depicted by Eileen Chang, which both shapes the city's spatial culture and represents the symbols of consumption in literary creation. Chang's literary also works embody a quality different from those of enemy-occupied areas.
