human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "cooperative isp traffic shaping schemes in broadband shared access networks"):
  Abstract: Traffic shaping is a mechanism used by Internet Service Providers (ISPs) to limit subscribers' traffic based on their service contracts. This paper investigates the current implementation of traffic shaping based on the token bucket filter (TBF), discusses its advantages and disadvantages, and proposes a cooperative TBF that can improve subscribers' quality of service (QoS)/quality of experience (QoE) without compromising business aspects of the service contract model by proportionally allocating excess bandwidth from inactive subscribers to active ones based on the long-term bandwidths per their service contracts.

Includes members:
  Member "a research framework for the clean slate design of next generation optical access":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "the effect of isp traffic shaping on user perceived performances in broadband access networks")
  Member "the effect of isp traffic shaping on user perceived performances in broadband access networks":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "stacked vlan based modeling of hybrid isp traffic control schemes and service plans exploiting excess bandwidth in shared access networks")
