  • Retention of a sub-network connection home path
    Patent number: 9088486
    Abstract: Embodiments of the present invention provide a method and system for reserving a connection's home path resources and restoring the connection on a link that includes a reserved priority bandwidth. A bandwidth advertisement indicating that the reserved priority bandwidth is available is analyzed and a restoration request requesting to route the connection on the link is sent. The reserved priority bandwidth is used to route the connection when the connection has a reserved home path on the link. When the connection has a reserved home path not on the link, a determination is made as to whether a normal priority bandwidth on the link is available and whether the connection is unrestorable on another link. The reserved priority bandwidth is used to temporarily route the connection when normal priority bandwidth on the link is unavailable and the connection is unrestorable on another link.
