(1 ) ISP计费设备获得非合作博弈(例如: 现有的评价计费, 即在一定 时间内向 P2P终端收取固定费用)时的上述 ISP计费设备的计费值 ( I SP计费设 备的初始计费值)和上述 P2P运营商计费设备的计费值(P2P运营商计费设备 的初始计费值 ) ;
其中, ISP计费设备将采用平价计费 (在一定时间内向 P2P终端收取固定 费用)所收取的费用减去成本作为其初始计费值, P2P运营商计费设备将广告 计费值作为其初始计费值;
例如: 现有的平价计费, 即在一定时间内向 P2P终端收取固定费用, 这种 计费方式对 P2P运营商计费设备不采取收费措施, 假设 ISP计费设备可以通过 长期市场成本 -收益分析, 以及与用户的交互得到的经验定价, 即平价计费中 的平均定价为 P。时,计费值最大。这时, P2P终端的 P2P下载流量为 "=^。 此时, ISP计费设备的计费值 r^ = NP- c(。), P2P运营商计费设备的计费 值 ^=3(^), 即确定了初始点 ( , Tp°sp ) 。 另外, 此时, P2P终端的计费 值 C ( +l
那么, 由 ISP计费设备的计费值 r^ = Np- c(。)可以看出, 成本越小, 则计 费值越大, 这使得 ISP没有改善网络质量、 提高 P2P终端的 P2P下载流量的激 励。
(2) ISP计费设备利用 NBS算法的帕累托特性, 根据获得的上述 ISP计费 设备的计费值和上述 P2P运营商计费设备的计费值获得上述 ISP计费设备与上 述 P2P运营商计费设备共同计费时的系统最大计费值及对应的 P2P流量; 例如: 如果 ISP计费设备和 P2P运营商计费设备采用基于合作博弈的 NBS 算法进行计费值划分, 则首先需要确定帕累托边界, 即二者合作可能达到的系 统最大计费值:
Ttotal = maximize(rB + TP2P) = maximize(_ (v) - C(v)) + NP0 (1 ) 其中, 可以将( 1 ) 式的最大值(即二者合作可能达到的最大计费值)处 对应的 P2P下载流量记为 , 此时最大的计费值记为 Tttal
(3)基于 NBS的定义, 双方通过找到在帕累托边界上, 且利用 NBS算法 的 NBG特性即纳什乘积最大时的值, 即取下列公式的最大值:
maximize ( TISP - Τ^) · ( ΤΡ2Ρ - ΤΡ°)
( ) subject to TISP+Tp2p=Ttotal
来确定公平的计费值划分, 同时求解出 与 ΓΡ*。 例如: 根据 Ρ2Ρ下载流量 Α , 得出: ISP计费设备的计费值 r; = NP。- C(A ), P2P运营商计费设备的计费值 T 2P =J(V*) , 即确定了进行计费值分配后的最大 点 ( ;SF , T;2F ) 。 另外, 此时, P2P终端的计费值 ^wig +i
(4) ISP计费设备根据上述 ISP计费设备的最大计费值和上述 P2P运营商 计费设备的最大计费值, 获得上述 P2P运营商计费设备对上述 ISP计费设备支 付的计费值 (即 P2P运营商需要支付给 ISP的费用) , 如下公式(3) 所示
R = T;SP-NP0 + C(V ) (3) 例如: 根据 和 τ , 得出 Ρ2Ρ运营商计费设备对 ISP计费设备支付的计 费值为 ^T^+cd^-Np。 (即 isp计费设备此时计费值为 N -c *), 而实际应 该得到得为 T;sp , 那么转移的应该为 KNP0 -C(v )) ) 。 具体地, 取 w=500, N=500 , Ρ0=100, v = aVc, y(v)=va , JL (v)=v\ l≤b〈a, 其中, 0≤a≤l可以看作是 ISP的改善因子, 例如: 通过升级 P2P终端的接入带 宽、 增加上传带宽等, 可以取 α=0.15, 那么 ^则可以看成是 Ρ2Ρ下载流量的上 限。
ISP计费设备与 Ρ2Ρ运营商计费设备在非合作博弈(例如: 现有的评价计 费, 即在一定时间内向 Ρ2Ρ终端收取固定费用) 时, ISP计费设备的计费值

ISP 计费设备与 P2P运营商计费设备在合作博弈时,

α = 1.2 , 6 = 1.1, 然后得出可以得出 =105, 可以看出, = ^即 为 Ρ2Ρ下载 流量的上限。 这时, rtoto,=7.84X105即为二者合作获得的最大收益。 rtoto,=7.84X105 可以反映出, P2P运营商计费设备对 P2P下载流量带来的收益增长速度要远 远大于这些产生的 P2P下载流量带来的成本, P2P运营商和 ISP可以以一种 合作的方式共同划分利益(即计费设备的计费值), 则 ISP计费设备依靠补偿 来升级网络, 将会提升 P2P下载流量的上限。 此时, 根据公式 (2), 可以得出 Γ; = 3.209X105 , Γ;2 -4.63Χ105, 以及根据公式 (3), 可以得出 = 5.37χ105。 此时,
Ρ2Ρ终端的计费值 Γ:=5.76χΐθ3。 与 ISP计费设备与 Ρ2Ρ运营商计费设备在 非合作博弈(例如: 现有的评价计费, 即在一定时间内向 Ρ2Ρ终端收取固定 费用) 时, ISP
