Dual-homing select architecture

A nodal system capable of recovering from nodal failures comprising:

• a first node, said first node having a first core router, a second core router, and at least one edge router homed to said first core router and said second core router, said node comprising a first select function, said first node capable of recovering from a first failure in said first node within said first node;
• and
• a second node, said second node having a first core router, a second core router, and at least one edge router homed to said first core router and said second core router, said node comprising a second select function couplable to said first node, said second node capable of recovering from a second failure in said second node within said second node, such that indicators of said first and said second failures are not communicated between said first and second nodes.

A network architecture for handling network failures comprising:

• a transport network capable of detecting and recovering from a failure in said transport network;
• and
• a first node, said first node having a first core router, a second core router, and at least one edge router homed to said first core router and said second core router, said node comprising a first select function coupled to said transport network, said first select function capable of detecting and recovering from failures in said first node, such that failures in said first node are not communicated over said transport network.

A node recovery method comprising the step of:

• recovering from a node failure within a node having a first core router, a second core router, and at least one edge router homed to said first core router and said second core router, such that in recovering from said node failure an indicator of said node failure is not externally communicated by said node.

A nodal recovery method comprising the steps of:

• recovering from a first node failure within a first node having a first core router, a second core router, and at least one edge router homed to said first core router and said second core router;
• and
• recovering from a second node failure within a second node having a first core router, a second core router, and at least one edge router homed to said first core router and said second core router, such that indicators of said first and second node failures are not communicated between said first and second nodes.

A network recovery method comprising the steps of:

• recovering from a transport network failure in a transport network;
• and
• recovering from a failure in a first node having a first core router, a second core router, and at least one edge router homed to said first core router and said second core router within said first node, such that in recovering from said failure an indicator of said failure is not communicated to a second node over said transport network.
