          Virtual Private Cloud

          Peer Connection

          Acquire Endpoint

          When confirming the Endpoint configured when you use the SDK, you can first read the section on VPC Service Domain Name in the Developer Guide to understand the Endpoint concept. Baidu AI Cloud currently opens the multi-region (Region) support. Please refer to the part of network product VPC in Region Selection Introduction. The peer connection services are a part of VPC services, and use the VPC service domain name.

          Get the Key

          To use Baidu Cloud products, you need to have a Baidu Cloud account and a valid AK (Access Key ID) and SK (Secret Access Key) for signature verification. You can obtain and understand your AK/SK information through the following steps:

          1.[Register Baidu Cloud Account](https://login.bce.baidu.com/reg.html? tpl=bceplat&from=portal) 2.[Create AK/SK](https://console.bce.baidu.com/iam/? _=1513940574695#/iam/accesslist)

          PeerConnClient

          The PeerConnClient encapsulates the API of peer connection services, and simplifies the interaction between developers and peer connection services. The users can call the methods in PeerConnClient to configure the peer connection.

          New PeerConnClient

          When creating PeerConnClient, you need to first use Endpoint, AK and SK to configure the BceClientConfiguration type config instance, and then use the config instance to configure the PeerConnClient. The specific configuration method is as follows:

          static final String HOST = "";
           static final String AK = "";
           static final String SK = "";
           PeerConnClientConfiguration config = new PeerConnClientConfiguration();
           config.setCredentials(new DefaultBceCredentials(AK, SK));
           config.setEndpoint(HOST);
           PeerConnClient peerConnClient = new PeerConnClient(config);

          Create a Peer Connection

          When the peer connection is created, attention should be paid to:

          • For the peer connection of the same account, the system will trigger the opposite terminal for automatic acceptance.
          • For the cross-account peer connection, the peer connection is available only after being accepted by the acceptor.
          • For the peer connections with the same local region and opposite terminal region, the billing parameter only supports the postpaid (the billing parameter should be transmitted, but the bill is 0).
          • Only one peer connection exists between any two VPCs.
          • The VPCs of the initiator and the acceptor cannot be the same.
          • If the local vpc and opposite terminal vpc are both relay vpcs, the peer connection cannot be established.

          The createPeerConn function can be used to create the peer connection in the specified VPC, and is defined as below:

          public CreatePeerConnResponse createPeerConn(CreatePeerConnRequest request) 

          For the definitions of CreatePeerConnResponse and CreatePeerConnRequest, refer to peerconn/model/ The parameters are described as follows:
