The new TextSecure push transport is a federated protocol
那是什么意思？
我认为这意味着一种通用的开放式协议,它允许许多小型网络相互通信,而不必完全放弃控制,因此他们仍然可以使用自定义内部协议.所以SMTP和XMPP是联合协议.我无法在任何地方找到确切的定义,但我确实有证据支持我的陈述：
动词“to federate”的字典定义：
(with reference to a number of states or organizations) form or be formed into a single centralized unit, within which each state or organization keeps some internal autonomy.
最近的blog post by Open Whisper Systems讨论了联合网络和集中网络：
Indeed, cannibalizing a federated application-layer protocol into a centralized service is almost a sure recipe for a successful consumer product today. It’s what Slack did with IRC, what Facebook did with email, and what WhatsApp has done with XMPP. In each case, the federated service is stuck in time, while the centralized service is able to iterate into the modern world and beyond.
This page将SMTP称为“联合电子邮件协议”：
Then, SMTP (Simple Mail Transfer Protocol) came along and allowed these systems to federate into one large email system.
(旁白：虽然我不是来自美国,但我觉得最容易将这个术语与美国“联邦政府”类比来考虑：它允许所有美国各州在国家层面进行协调,同时仍保留大量内部控制)
