Re: [OpenDaylight TSC] Switch project leader
Ryan Goulding <ryandgoulding@...>
PTL title comes with responsibilities in ODL beyond committer. I think it is important to preserve a sole point of contact for the PTL position; since that person votes for their representative project regarding releases/delays etc. This is just my $0.02 though. Regards, Ryan Goulding

Putting Jensen as the one and only

I am just curious, will one as PTL, the other as project contact work for you.
Having multiple PTLs for one project has no precedent, I just want to point this out, not necessarily against it.

Yes, of course. Actually, it is him that comes up with the suggestion. Since he is not a committer, I start the voting for him.
Thanks, Tony

Dear TSC,
We have carried out a public vote for switching project leader in ALTO project [1][2][3]. We, all committers, agree that we switch Jensen Zhang as co-lead instead of Shu. Thanks, Tony

NetJSON and ALTO
Y. Richard Yang
It may make sense for some of us to take a look at NetJSON. Wendy gave a thorough response, and some of us may want to take a close look as well. Richard ---------- Forwarded message ---------- From: Wendy Roome <w.roome@...> Date: Mon, Sep 21, 2015 at 10:50 AM Subject: Re: NetJSON and ALTO To: alto@... Cc: hrogge@..., aaron@..., "Y. Richard Yang" <yry@...>, manet@..., nemesis@... Thanks for letting the ALTO group know about NetJSON. NetJSON is related to the proposed ALTO extensions to describe network topology. However, I think ALTO's needs are sufficiently different, and sufficiently simpler, that there is no advantage using NetJSON in ALTO. The proposed ALTO topology extensions give clients a very simple, abstract view of the network so that clients can determine how much the paths between endpoints overlap. E.g., suppose a client wants to do parallel backups to two different cloud servers. If the paths to servers A & B have many common elements, while the paths to servers A & C do not, the client would prefer to use A & C. ALTO could use the NetJSON NetworkGraph sub-schema to describe topology, but that is considerably more complicated than what we have proposed. For example, a NetworkGraph has nodes, links that connect nodes, and descriptions of routing protocols. The front-runner for describing topology in ALTO is to provide a list of abstract network elements involved in the path between two endpoint clusters. The elements can be nodes, links, or combinations of those. A NetJSON NetworkGraph is considerably more complicated, and much closer to the physical network. Also, ALTO clients are typically enduser applications with minimal knowledge of network internals. They want ALTO to hide the details and give them just what the need, and no more. So few ALTO clients would need the rest of NetJSON, and forcing them to learn it would just make it harder to use ALTO. Similarly, I doubt that NetJSON libraries would simplify ALTO clients; it would just mean a client has to learn how to turn off features the client will never use. - Wendy Roome >Date: Mon, 14 Sep 2015 10:05:31 +0000 >From: Rick Taylor <rick@...> >To: Henning Rogge <hrogge@...>, "L.

Switch project leader
xin wang
Dear all committers,
Since Shu got a high work load recently and he is not able to focus on ALTO project. I'd like to propose that we switch Jensen Zhang to be a co-lead of ALTO project. Jensen has been being involved in the project actively since ALTO Lithium release [1] and he will for sure contribute more in the future. Please vote +1, 0, -1 for the proposal. Thanks. [1] https://git.opendaylight.org/gerrit/#/q/project:alto+owner:jensenzhang. Thanks again, Tony

Re: Propose Jensen to be co-lead of ALTO
Gao Kai
Shu, It’s nice to hear from you and I support the idea of making Jensen a co-leader. However, there are some procedures I’d like to point out: First according to this, this and this, only the commiters can vote for committer nominations and project leader election. According to Collin, a member of ODL TSC, there are only 4 committers and since there was no voting (as far as I know) you and I are not legal project leaders at the moment. It would be great if someone can continue to push forward the process of committer nominations and also this co-lead election. One major issue is that we must get at least 3 votes from the four committers, especially from Shi and Wendy. Regards,
On 21/10/15 21:26, Shu

I made some changes to make the nearest-anchor more general. Please see below. On Tue, Oct 20, 2015 at 1:10 PM, Y. Richard Yang <yry@...> wrote:
"anchors": [ "pid1": ["sw1", "sw2"] , "pid2" : ["sw3"], "pid3": ["sw4", "sw5"] ], Hence each PID is seeded with a set, instead of a single switch. We can then approximate other design, for example using regular expressions. Richard

Re: alto pids
Y. Richard Yang
Good discussions. I have reported it as a bug in https://github.com/snlab/alto. In addition to reporting as a bug, which helps us to get priority, let's start some specific discussions. What we need is a mechanism so that an admin can define the partition of hosts into PIDs. Let me give a try to start a strawman. We can consider the hosts in the network as leaves in a graph. Each host also has a set of attributes (e.g., geolocation) beyond the graph properties. Hence, I assume that we need a mechanism to use these properties to group the hosts. A first idea coming to mind is cluster analysis (https://en.wikipedia.org/wiki/Cluster_analysis). Let me start with an anchor based approach. Assume that we allow the admin to define a set of anchors, where each anchor is a switch. { "netmap-grouping-alg": "nearest-anchor", "alg-metric": "hopcount", // it could be "nearest geo-location", if we know "anchors": [ "sw1", sw3", "sw4"], "cost-map-cal-alg": "avg" // cost from pid1 (sw1 cluster) to pid2 (sw2 cluster) is the average of host pairs } Then we can see that it defines three PIDs, where each PID is defined by an anchor in anchors. When an host is added, we can automatically compute which anchor is the nearest and hence assign it to it. We can prove that each PID is a connected component, if we assume the full graph is connected, when we consider graph hopcount. How to define a more general mechanism? Richard
