> # Abstract
> The qpid-proton 'messenger' implementation currently uses hard-coded
> receiver-xxx and sender-xxx link names for all attachments.
> # Description
> I believe the AMQP 1.0 spec says here that:- although client-ids do not need
> to be unique, the triplet of <client-id>, <link-name> and <server-id> *is*
> guaranteed to be unique.
> http://docs.oasis-open.org/amqp/core/v1.0/os/amqp-core-transport-v1.0-os.html#doc-idp298752
> However, the qpid-proton Messenger code seems to have all link-name's
> hard-coded to sender-xxx and receiver-xxx
> As an easyfix, I would suggest that by default the topicname part of the
> address should be appended to the link-name (instead of -xxx)
> e.g., amqp://localhost/topicName --> sender-topicName / receiver-topicName
> However, that would still cause a clash if the same messenger wanted to make
> two subscriptions to the same topic, so perhaps the Messenger implementation
> needs to track what link names it has allocated and ensure a unique name is
> assigned each time?
