Brian -------- Forwarded Message -------- Subject: Prefix manager code updated Date: Sun, 7 May 2017 15:04:17 +1200 From: Brian E Carpenter Organization: University of Auckland To: Anima WG Hi, I've uploaded a new improved version of my demo code for draft-ietf-anima-prefix-management. It can be found at https://www.cs.auckland.ac.nz/~brian/graspy/pfxm2.py, but I advise reading the implementation notes first: https://www.cs.auckland.ac.nz/~brian/graspy/pfxm2.pdf . There's also a screen shot at https://www.cs.auckland.ac.nz/~brian/graspy/prefixen.png . This shows a 'master' prefix manager (bottom left) and four prefix delegators in action, all running on the same machine (but independent GRASP instances). It works between machines too, but that's hard to capture in a screen shot. TL;DR: "Apart from figuring out the bit manipulations and eliminating a few fencepost errors, this was quite easy work. I think it shows that the whole mechanism is viable. With stable storage added, and a secure ACP, it should be safe for real world use. Expansion to cover IPv4 as well would be straightforward, if the objective format allowed it."

First, here is one of the definitions: > CASM Coordinator: A management system which has a centralized > database manage the overall address pools and allocate address > pools to the device in the devices. Ther is no need for this database to be centralized or for the allocation of address pools to be centralized. It can be done with a completely distributed system. (I agree that centralized logging might be needed.) In fact, sections 4.2 and 4.3 describe a centralized model for everything, not just for logging. Could we perhaps agree that this is only one possible architecture? If so, we would also need a second draft describing a distributed architecture. It's quite hard to cover both designs in one document. > The overall procedure is as follows: > > o Operators will configure remaining address pools centrally in the > Address Pool Management System (APMS). There are multiple address > pools which can be configured centrally. The APMS server will > then divide the address pools into addressing unit (AU) which will > be allocated to the agent in devices by default. Certainly the NOC will configure initial address pools into a master agent. But from that moment, a distributed process can take over in which pools (prefixes) will allocated to distributed agents on demand, with no need for default allocations. > o If the lifetime of the address pool is going to expire, the DA > should issue an AddressPoolRenew request to extend the > lifetime,including the IPv4, IPv6, Ports, etc. A couple of questions on this.: 1. Why is the lifetime useful? Firstly, once an address has been allocated to an end-user, it must be left there as long as necessary; you can't recover an address while it is in active use. That will block the address pool that contains it indefinitely, so what is the value of the lifetime? Secondly, if there is no lifetime, the agent can release the address pool on demand if it is not in use. Again, there is no value in the lifetime that I can see. 2. Is it really useful to include the notion of ports in an address pool? In the case of IPv6 it is definitely useless. In the case of IPv4 with A+P (port-based address sharing, RFC6346), surely you never want to share a single address across different agents? That would lead to complex and fragile CASM operations at rather high frequency. RFC6346 defines how A+P gateways may talk to each other (horizontally, not north-south) to share an address using A+P. You seem to be duplicating that function. Also, RFC7768 seems to assume that port sharing occurs entirely within a single CGN. So it seems to me that it's wrong to include port ranges in the CASM model. (Note: I have no problem with 'port-range' being defined in the CASM YANG model; that seems necessary for completeness. My problem is with using it in network-wide resource management, which doesn't seem reasonable.) > 5.1.1.1. Address pools ... > o IPv6 addresses I suggest dividing this into 'Globally routable' and 'ULA' > o MAC Addresses Can you explain this? Where do layer 2 addresses fit in? ... > Multicast address pool: This topic needs more discussion.
