Abstract: A first transport protocol connection is established between a first proxy network element and a second proxy network element. The first proxy network element receives from a first Border Gateway Protocol (BGP) client, first BGP data destined to a second BGP client that is connected to the second proxy network element. The first BGP data is transmitted to the second proxy network element through the first transport protocol connection for delivery to the second BGP client. The first proxy network element receives second BGP data destined to the second BGP client. Responsive to determining that the first transport protocol connection is down, the first proxy network element stores the second BGP data and establishes a second transport protocol connection to the second proxy network element. The second BGP data is transmitted to the second proxy network element through the second transport protocol connection.

Abstract: Method and network elements (NEs) for enabling reliable application layer data transmission through an unreliable network are described. A proxy NE receives from a first NE through a first transport protocol connection first application layer data. The proxy NE transmits the first application layer data through a second transport protocol connection towards the second NE. The proxy NE receives from the first NE through the first transport protocol connection second application layer data that is destined to the second NE. Responsive to determining that there are no transport protocol connections for transmitting the second application layer date, the proxy NE stores the second application layer data in the first proxy NE. Responsive to determining that a third transport protocol connection is established towards the second NE, the proxy NE transmits the second application layer data through the third transport protocol connection towards the second NE.
