ZEC Adding TCP Outputs

the tcp protocol provides a reliable transmission guarantee for no loss of frames its bandwidth probing and congestion control will attempt to use all of the available bandwidth between the server and client, fetching content as quickly as possible while being friendly to other (tcp) traffic on the same links the tcp output can push the stream directly to a tcp socket or to an http server multipath tcp developed by the internet engineering task force's (ietf) multipath tcp working group, multipath tcp (mptcp) is an effort towards enabling the simultaneous use of several ip addresses/interfaces by a modification of tcp that presents a regular tcp interface to applications, while in fact spreading data across several subflows zixi supports multipath tcp for linux based on the os kernel support this means that the linux kernel should be updated to support mptcp for detailed information on how to update the kernel and use mptcp, see zec configuring multipath tcp docid\ rh a rvbcqq54hs1wqlwv the mptcp functionality is similar to zixi's "multi link bonding" feature, which is available for udp only in this case, mptcp works on tcp if both the sending end and the receiving end support multipath tcp, zixi can use this functionality to transmit a stream over tcp using multiple network interfaces (e g , wi fi + mobile) the multiple links can be configured to aggregate aggregate the bandwidth of the multiple links in order to use the total capacity of the links in this case, zixi will use all available bandwidth among all available flows (if needed) to send the stream duplicate enhance the path's resiliency by duplicating the stream and sending it through multiple links in order to overcome errors and packet loss to create a tcp output in the zec outputs page, click +new output the new output window is displayed type in the unique identifier for this output in the output name select an input stream to be made available on this output from the drop down list select the show in matrix check box to display this stream in the matrix (see zec using the matrix docid\ ofxethpsuo9eimqpwfzea ) default selected select tcp specify the output parameters (see output stream parameters table docid\ gtlybfavkasmjpkv2lmvt below) if the target is an http server, select the http checkbox in this case, http headers will be added to the stream enter additional parameters as necessary ( see output stream parameters table docid\ gtlybfavkasmjpkv2lmvt ) you can decrypt an encrypted stream as it enters the zec to decrypt a stream, select the decrypt stream checkbox and fill in the parameters as described in the output stream parameters table docid\ gtlybfavkasmjpkv2lmvt below for more information, see decrypting an output stream in zec docid\ fqloypidpib19cqfvu8rz click ok the new tcp output with its settings is created and now appears on the screen output stream parameters table parameter description output parameters host the destination host for the stream port specify the ports to listen on for tcp streams default 7777 http if the target is an http server, select the http checkbox in this case, http headers will be added to the stream \<font color="#0c121d">multi path tcp\</font> \<font color="#0c121d">select this checkbox to enable multipath tcp, which enables the transmission of a stream over tcp using multiple network interfaces (e g , wi fi + mobile) multi path tcp is available for linux only \</font> mode the multiple links can be configured to aggregate aggregate the bandwidth of the multiple links in order to use the total capacity of the links in this case, zixi will use all available bandwidth among all available flows (if needed) to send the stream duplicate enhance the path's resiliency by duplicating the stream and sending it through multiple links in order to overcome errors and packet loss enable decryption select this checkbox to enable decryption of an encrypted stream decryption type if the stream has been encrypted, you can decrypt it through the output by selecting this checkbox and specifying the type of encryption that was used select automatic to decrypt a stream that has been encrypted using automatic encryption only if the stream has not been encrypted, select none (default) important notice if the stream has been encrypted, you must decrypt it in the output decryption key enter the decryption key to decrypt the encrypted stream
