The explanation of the diagram is as follows: There is a Fabric network N with network policy NP1 and ordering service O. Channel C1 is governed by channel policy CP1. Channel C1 has been established by consortium RARB. Channel C1 is managed by ordering service O and peers P1 and P2 and client applications A1 and A2 have been granted permission to transact on C1. Client application A1 is owned by organization RA. Certificate authority CA1 serves organization RA. Peer P2 maintains ledger L1 associated with channel C1 and L2 associated with C2. Peer P2 makes use of chain code S4 and S5. The orderer nodes of ordering service O are owned by organization RD.
创建网络网络的创建是由客户端，peer节点，channel通道和ordering服务节点的联盟创建的 。排序服务是网络中的地位十分重要，因为它包含着网络中的通道的配置 。每个通道的配置包含通道的策略和membership信息（比如X509根证书） 。

The network is created from the definition of the consortium including its clients, peers, channels, and ordering service(s). The ordering service is the administration point for the network because it contains the configuration for the channel(s) within the network. The configurations for each channel includes the policies for the channel and the membershipinformation (in this example X509 root certificates) for each member of the channel.
