Hi All,
With this update in the I.D., we have -
~ Removed any code points from the I.D. TBA by IANA and corresponding update in
the IANA section.
~ Objective Function: Adding a new objective function to minimize packet loss
called MPLP (Minimum Packet Loss Path).
As this is the only technical change, I am listing it right here for a quick
look:
o A network comprises a set of N links {Li, (i=1...N)}.
o A path P is a list of K links {Lpi,(i=1...K)}.
o Packet loss of link L is denoted PL(L) in percentage.
o Packet loss in fraction of link L is denoted FPL(L) = PL(L) / 100.
o The Packet loss of a path P (in percentage) is denoted PL(P),
where PL(P) = (1 - ((1-FPL(Lp1)) * (1-FPL(Lp2)) * .. *
(1-FPL(LpK))) * 100.
Objective Function Code: (TBA - IANA)
Name: Minimum Packet Loss Path (MPLP)
Description: Find a path P such that PL(P) is minimized.
~ Editorial Changes: Removing reference from abstract; changing reference
names; etc

We currently have no open issues in the draft.
On behalf of the co-authors and contributors, we request WG to look at the
document and provide us with any comments/suggestion to help progress the draft.

> Abstract:
> In certain networks like financial information network (stock/
> commodity trading) and enterprises using cloud based applications,
> Latency (delay), Latency-Variation (jitter) and Packet Loss is
> becoming a key requirement for path computation along with other
> constraints and metrics. Latency, Latency-Variation and Packet Loss
> is associated with the Service Level Agreement (SLA) between
> customers and service providers.
>
> IGP Traffic Engineering (TE) Metric extensions describes mechanisms
> with which network performance information is distributed via OSPF
> and IS-IS respectively. The Path Computation Element Communication
> Protocol (PCEP) provides mechanisms for Path Computation Elements
> (PCEs) to perform path computations in response to Path Computation
> Clients (PCCs) requests. This document describes the extension to
> PCEP to carry Latency, Latency-Variation and Packet Loss as
> constraints for end to end path computation.
