Describes a relationship between a socket and all sockets to which it is connected.

Variants

Bus0

Version 0 of the bus protocol.

The bus protocol provides for building mesh networks where every peer is connected to every other peer. In this protocol, each message sent by a node is sent to every one of its directly connected peers. See the bus documentation for more information.

Pair0

Version 0 of the pair protocol.

The pair protocol implements a peer-to-peer pattern, where relationships between peers are one-to-one. See the pair documentation for more information.

Pair1

Version 1 of the pair protocol.

The pair protocol implements a peer-to-peer pattern, where relationships between peers are one-to-one. Version 1 of this protocol supports and optional polyamorous mode. See the pair documentation for more information.

Pub0

Version 0 of the publisher protocol.

The pub protocol is one half of a publisher/subscriber pattern. In this pattern, a publisher sends data, which is broadcast to all subscribers. The subscribing applications only see the data to which they have subscribed. See the publisher/subscriber documentation for more information.

Pull0

Version 0 of the pull protocol.

The pull protocol is one half of a pipeline pattern. The other half is the push protocol. In the pipeline pattern, pushers distribute messages to pullers. Each message sent by a pusher will be sent to one of its peer pullers, chosen in a round-robin fashion from the set of connected peers available for receiving. This property makes this pattern useful in load-balancing scenarios.

See the pipeline documentation for more information.

Push0

Version 0 of the push protocol.

The push protocol is one half of a pipeline pattern. The other side is the pull protocol. In the pipeline pattern, pushers distribute messages to pullers. Each message sent by a pusher will be sent to one of its peer pullers, chosen in a round-robin fashion from the set of connected peers available for receiving. This property makes this pattern useful in load-balancing scenarios.

See the pipeline documentation for more information.

Rep0

Version 0 of the reply protocol.

The rep protocol is one half of a request/reply pattern. In this pattern, a requester sends a message to one replier, who is expected to reply. The request is resent if no reply arrives, until a reply is received or the request times out.

See the request/reply documentation for more information.

Req0

Version 0 of the request protocol.

The req protocol is one half of a request/reply pattern. In this pattern, a requester sends a message to one replier, who is expected to reply. The request is resent if no reply arrives, until a reply is received or the request times out.

See the request/reply documentation for more information.

Respondent0

Version 0 of the respondent protocol.

The respondent protocol is one half of a survey pattern. In this pattern, a surveyor sends a survey, which is broadcast to all peer respondents. The respondents then have a chance to reply (but are not obliged to reply). The survey itself is a timed event, so that responses received after the survey has finished are discarded.

See the survery documentation for more information.

Sub0

Version 0 of the subscriber protocol.

The sub protocol is one half of a publisher/subscriber pattern. In this pattern, a publisher sends data, which is broadcast to all subscribers. The subscribing applications only see the data to which they have subscribed.

See the publisher/subscriber documentation for more information.

Surveyor0

Version 0 of the surveyor protocol.

The surveyor protocol is one half of a survey pattern. In this pattern, a surveyor sends a survey, which is broadcast to all peer respondents. The respondents then have a chance to reply (but are not obliged to reply). The survey itself is a timed event, so that responses received after the survey has finished are discarded.

See the survey documentation for more information.
