例如下面这段话中的metrics应该怎么翻译？
We used the following metrics to evaluate system performance:
 Path length: the number of (application-level) hops required
to route between two points in the coordinate space.
 Neighbor-state: the number of CAN nodes for which an individual
node must retain state.
 Latency: we consider both the end-to-end latency of the total
routing path between two points in the coordinate space
and the per-hop latency, i.e., latency of individual application
level hops obtained by dividing the end-to-end latency by the
path length.
 Volume: the volume of the zone to which a node is assigned,
that is indicative of the request and storage load a node must
handle.
 Routing fault tolerance: the availability of multiple paths
between two points in the CAN.
 Hash table availability: adequate replication of a (key,value)
entry to withstand the loss of one or more replicas.
