Unirest Proxy

It means routing traffic from multiple devices through a single proxy server. In this way you can, for example, organize a local network in an office environment, but where all the traffic data can be viewed from the administrator's server.

The maximum size of an RTP (Real-time Transport Protocol) packet when transmitted over TCP/UDP protocol depends on the payload size and the addition of RTP header information.

RTP is a transport protocol specifically designed for real-time applications like audio and video streaming. It is typically used in conjunction with UDP or TCP, as it does not provide its own transport layer.

RTP packets consist of two parts:

1. Payload: This is the actual data being transmitted, which can be audio, video, or other real-time data. The payload size is determined by the application or codec being used.

2. Header: The RTP header contains metadata required for the proper processing and synchronization of the payload. The header has a fixed size of 12 bytes. The maximum size of an RTP packet can be calculated by adding the payload size and the fixed header size:

Maximum RTP packet size = Payload size + 12 bytes (RTP header)

The payload size depends on the application or codec being used. For example, if you're using an audio codec that generates 100-byte audio frames, the maximum RTP packet size would be:

Maximum RTP packet size = 100 bytes (payload) + 12 bytes (RTP header) = 112 bytes

In the case of video codecs, the payload size can be significantly larger, depending on the video resolution, compression, and frame rate.

When RTP is used over TCP or UDP, the maximum size of the RTP packet is limited by the maximum payload size supported by the underlying transport protocol. For TCP, the maximum segment size (MSS) is determined by the MTU (Maximum Transmission Unit) of the network and the TCP header size. For UDP, the maximum packet size is limited by the MTU of the network and the UDP header size.

In summary, the maximum size of an RTP packet when transmitted over TCP/UDP protocol depends on the payload size and the addition of RTP header information, as well as the underlying transport protocol's limitations.

Proxy service settings refer to the configuration and settings related to the use of a proxy server. A proxy server is an intermediary server that sits between a client and a destination server, acting as an intermediary to request and deliver content on behalf of the client. The main purpose of a proxy server is to improve performance, enhance security, or bypass restrictions on accessing certain content.

Proxy service settings include the following components:

1. Proxy server address: The IP address or domain name of the proxy server that the client will use to route requests and receive responses.

2. Proxy server port: The port number on which the proxy server is listening for incoming connections.

3. Protocol: The communication protocol used by the proxy server, such as HTTP, HTTPS, or SOCKS.

4. Authentication: The credentials required to access the proxy server, including username and password, if the proxy server requires authentication.

5. Connection timeout: The maximum amount of time, in seconds, that the client will wait for a response from the proxy server before timing out and attempting to reconnect.

6. Socks version: The version of the SOCKS protocol used by the proxy server, such as SOCKS4 or SOCKS5.

7. Proxy type: The type of proxy server, such as HTTP, HTTPS, or SOCKS, that the client will use to route requests and receive responses.

8. Bypass list: A list of domains or IP addresses that the client will bypass the proxy server for, allowing direct access to those resources.

9. Connection encryption: The method used to encrypt the data transmitted between the client and the proxy server, such as SSL or TLS.

10. User-agent: The user-agent string that the client will use to identify itself to the proxy server and destination server.

Technically, ISP can block only some intermediary servers by IP-addresses. But it's impossible to block absolutely all VPN-servers, because there are so many of them and their addresses are constantly changing. Accordingly, in this case, you just need to use another VPN-server.

There are HTTP proxy, FTP proxy, SOCKS proxy, SMTP proxy, CGI proxy. They differ only in the data transmission protocol used and the purpose for which they are used. For example, SMTP proxy allows you to organize a secure server for e-mail.
