如果程序权限不足,尝试以更高权限运行程序,或者调整系统的安全策略以允许当前用户访问该端口。 通过上述步骤,你应该能够定位并解决 "p2p start port error" 的问题。如果问题仍然存在,可能需要更详细地检查程序的日志输出或咨询相关的技术支持。
客户端向NAT穿透服务器发起UDP请求若干次,如每次超时未返回,即认为该客户端不具备UDP通信能力(可能是前端防火墙或NAT阻止UDP通信);若客户端收到NAT穿透服务器返回的数据包,则比较数据包中携带的客户端(IP,port)和socket(IP,port):如果两者完全相同则客户端不在NAT后,这样的客户端具有公网IP,可以直接监听UDP端口接收...

(1)使用同一个目的port的p2p协议传输的tcp流特征相似度高达99%。如果他们是cc通信,那么应该都算在一起,反之就都不是cc通信流。 (2)使用不同目的端口的p2p协议传输的tcp流相似度不太一样,相似度从0.4-0.99之间。 数据: 1 2 3 4 5 6 7 8 9
When deregistering peers, the new DropPeer functionality will deregister every peer with a given IP address. It needs to additionally consider the port, so nodes with the same IP address are not wholesale dropped. This is what's been causing the P2P convergence CI tests to fail....
PortAllocatorSession的生命周期应该和P2PTransportChannel的生命周期一样,因为它产生的候选项以及Port本身就是服务于P2PTransportChannel的,当点对点的会话结束的时候,自然它也就没有存在的意义了. 验证,在P2PTransportChannel的类结构定义中,我们发现了成员 std::vector<std::unique_ptr<PortAllocatorSession>>allocator_ses...

P2P Product The P2P networking grandly launched by Shanghai ZLAN is a new technology for serial port networking. Different from the traditional TCP/IP connection style based on IP plus port, P2P technology proceeds communication on the basis of device ID. Users only need to input device ID so...
