Abstract:
1. A method for improving network connection, comprising: detecting a first checking message (“CM”) formatted in a connectivity verification protocol (“CVP”) by a first network element (“NE”) indicating a primary link failure between the first NE and a first router situated in a first network; sending a second CM formatted in the CVP indicating the primary link failure from the first NE to the first router via a primary virtual LAN (“VLAN”); retransmitting the second CM from the first router to a second NE situated in a second network via a primary pseudo-wire (“PW”) for notifying the second NE to switchover from a primary link to a backup link; switching over from the primary link to the backup link at the second NE in response to the second CM utilizing a circuitry of protocol bundle; and sending an acknowledge message formatted in a protection switching protocol operable in the first network from the second NE to the first NE.
