Decisions and action points
- WG2/WG4 overlapping
Edmundo Monteiro, WG2 chairman, presented the scope of WG2 on Scalable Networking and its Task Forces:
- TF2.1 Scalable routing
There is a strong overlap with TF4.2 on TE
- TF2.2 Distributed router architecture to gain scalability
There is an overlap with WG5, but this issue is already solved with the inclusion of the research topic in WG5
- TF2.3 Traffic driven scalability
There is a strong overlap with TF4.1 on measurements
Although we were supposed to discuss only the TE/Routing overlapping, it became immediately clear that the TF2.3/TF4.1 overlapping on measurements would have to be solved in the same manner.
Several ways to solve these overlappings were listed and discussed, namely:
- (a) Leave things as they are now: Keep WG2 and WG4 as is, both with 2 TFs
- (b) Keep WG2 and WG4 separated, but
- Merge TF2.1 and TF4.2 (as joint TF on TE/Routing)
- Merge TF2.3 and TF4.1 (as joint TF on Measurements)
- (c) Merge WG2 and WG4, and
- Merge TF2.1 and TF4.2 into a TF on TE/Routing
- Merge TF2.3 and TF4.1 into a TF on Measurements
- (d) Merge WG2 and WG4, and
- Keep TF2.1 on QoS Routing
- Keep TF4.2 on TE
- Merge TF2.3 and TF4.1 into a TF on Measurements
- (e) Redefine WG2 and WG4:
- WG2 on Routing and TE with one or two TF's
- WG4 on Measurement with one TF
After some discussion, we decided to vote:
- solution (a) got 0 vote
- solution (b) got 0 vote
- solution (c) got 11 votes
- solution (d) got 2 votes
- solution (e) got 5 votes
- others abstained
The group is thus largely is favour of merging WG2 and WG4 as well as its TFs.
It is understood that solution (b) can be an intermediary step towards solution (c), and that solution (b) is definitely much better than (a).
Also, solution (d) could be envisaged later if it turns out that a separate TF on QoS routing, clearly distinct from TE, has critical mass.
Therefore if WG2 agrees, we recommend that the WG2 and WG4 chairpersons jointly inform the management committee and ask for the merging. Until then, both WG2 and WG4 continue as before, but with joint TF's (i.e. intermediary solution (b)).
- Joint paper for the special issue of Computer Communications
G. Leduc introduced the topic. The timing is very short. An extended abstract is due by the 30th of April 2004. If accepted, a full paper should be submitted by the 15th of July 2004 and a final version by the 30th of September 2004
After some discussion on possible structures for the paper, the one that received the largest support is the following.
Title: "An open source traffic engineering toolbox" (to be finalized)
The expected structure (already adapted a bit) would be:
1. Motivation for an open source TE toolbox
2. Software architecture of the toolbox
3. TE algorithms of the toolbox
3.1. IP-based TE algorithms (Intra-domain and inter-domain)
3.2. MPLS-based TE algorithms (Intra-domain and inter-domain)
4. Other tools (e.g. Topology managers, XML tools, etc.)
Several research groups have volunteered to write a section of the paper:
- ULg will write sections 1 and 2.
- UCaL will coordinate (and write parts of) section 3.1
- FTW, SICS and ETH may contribute to section 3.1 (to be confirmed). The former two on intra-domain and the latter on inter-domain.
- ULg will coordinate (and write parts of) section 3.2
- U. Trento and FTW may contribute to section 3.2 (to be confirmed) on intra-domain MPLS TE
- UPC may also contribute (to be confirmed).
- ULg will coordinate (and write parts of) section 4.
- U. di Napoli will contribute to section 4 on a graphical XML editor.
This discussion has been related to another possible paper from TF2.1 on QoS Routing along the following lines (the names between parentheses being the expected contributors):
1. Motivation for QoS routing (TUDelft)
2. Intra-domain issues (UC, UPC)
2.1. Content aware network routing
2.2. Multicast routing
3. Inter-domain issues (UPC, UC)
3.1. Overlay approaches
3.2. Multi-homing
3.3. Load-Balancing and fault tolerance
3.4. Policy verification
4. Other issues
4.1. Route optimization (U. Napoli)
4.2. Updating strategies
4.3. QoS routing for mobile (LIP6, WG1)
4.4. QoS routing for p2p (WG3)
This structure is just given for information because it has to be finalized by WG2. The important issue was essentially to check whether there was an overlap with the previous paper or not. As the answer is clearly negative, both proposed papers can be further worked out without any coordination.
- Availability of testbeds
Several partners have testbeds and are ready to host experiments jointly with other partners.
It was decided that all partners willing to provide a testbed environment in WG4 would have to put a description on the web page of WG4 (testbeds are indeed valid for both TF's).
The deadline for making these descriptions available is : 15th of June 2004.
- Web page of Task force 4.2
ULg will set up the Task Force 4.2's web page and will initially populate it with the presentations of the inaugural meeting of April 15th and with the present minutes.
All partners should send G. Leduc an URL where their slides in pdf format are available.
