hwMplsPsType

The type of protection switch,can be 1:1,1+1,shared mesh,
packet 1+1,the default choice is 1:1.
In the 1+1 architecture type, a protection LSP is dedicated to 
each working LSP with the working LSP bridged onto the 
protection LSP at the source of the protection domain. 
The traffic on working and protection LSPs is transmitted 
simultaneously to the sink of the protection domain, 
where a selection between the working and protection LSP is 
made, based on some predetermined criteria, such as defect 
indication.
In the 1:1 architecture type, a protection LSP is dedicated to 
each working LSP. The working traffic is transmitted either by 
working or protection LSP.
In the shared mesh architecture type, possible sharing of 
protection capacity between disjoint link, node in the network 
is achieved while guaranteeing recovery from a single failure.
In the packet 1+1 architecture type, the traffic is transmitted 
simultaneously onto two possibly disjoint routed LSPs to the 
sink of the protection domain. Each pair of duplicate 
transmitted packets is assigned the same identifier (sequence 
number) but distinct from the other pairs of duplicate packets. 
At the sink of the protection domain packet level selection 
mechanism is employed to select one of the two possibly 
received copies of each packet. 
1:  1:1 protection switching,;
2:  1+1 protection switching;
3:  shared mesh protection swiching;
4:  packet 1+1 protection switching.
