Bounding Numerical Dev
- Numerical deviation bounds the difference between the conit value and relative value of last update. A weight can be assigned to the writes which defines the importance of the writes in a specific application. The total weights of unseen writes for a conit can be defined as a numerical deviation in an application

Bounding Ordering Dev
- Ordering deviation is the discrepancy between the local order of writes in a replica and their relative ordering in the eventual final image

Bounding Staleness Dev
- Staleness deviation defines the validity of the oldest write by bounding the difference between the current time and the time of oldest write on a conit not seen locally. -faris

Bounding ordering:
- Deviation with respect to the ordering of update operations. Maximum number of uncertain writing that replica servers update when it received it. A specified maximal length of queue is used to bound the ordering deviation. 

Boundering numerical: 
- Deviation in the numerical values between replica servers. Mostly focusing on keeping the numerical deviation within the fixed value and emphasize on writing to 1 item instead.

Bounding staleness:
- Deviation in the staleness(refers to age or timestamp of update) between replicas to ensure each replicas are consistent.

Bounding Numerical Dev: Refers to the value by which replicas maybe different. A solution for keeping the numerical deviation within bounds. 

Staleness Dev: Refers to the time by which a replica is still considered to be consistent. Relate to the last time a replica was updated. Eg: used in web caches

Ordering Dev: Refers to the maximum number of tentative writes that may be outstanding without having synchronized with other replica servers.

Bounding Staleness Deviation: Way to keep the staleness of replicas within specified bounds. For example, one approach like timestamp each submitted write by its origin server. 

Bounding Ordering Deviation: Replica server tentatively applies updates that have been submitted to it. The ordering deviation is bounded by specifying the maximal length of the queue of tentatives writes.

Bounding Ordering Deviations -
Replica server tentatively applies updates that have been submitted to it... and each server will have a local queue of tentative writes(order yet TBD)

Bounding Numerical Deviations-
()
A server pushes a series of write commands to its nearest neighbors (epidemic protocol)... If a receiving server senses that it is not keeping pace with its updates, it asks the sender to push its current state

Bounding Staleness Deviation -
(TIMESTAMP)
Every server keeps a vector clock... When a receiving server sees that its vector clock is falling behind the sender's, it pulls the most recent update
  1. one approach->> timestamp each submitted write by its origin server
