Looking for North American Carriage providers
by Ben Cornish 05 Apr '12

05 Apr '12

Hi All, I apologize for the Spam - We recently expanded into North America from Australia to service our Australian Clients with their international needs. We are seeking a Carrier or few carriers that can provide us with layer 2 Ethernet services that has coverage to the majority of North America. We are looking at the smaller services of 2 to 20mb area. Preferable handoff in Equinix-SV1(San Jose) or 1 Wilshire(Coresite LA) as VLAN's Seeking responses off list please. Cheers.

CAIDA's 2012 IPv6 survey -- need network operators to fill out
by k claffy 04 Apr '12

04 Apr '12

[direct link to IPv6 operational deployment [plans] survey if you don't need background: http://www.surveygizmo.com/s3/749797/ipv6survey ] hello folks, we're trying to do some quantitative modeling of the IPv4->IPv6 transition, including the impact of IPv4 markets on likely future trajectories, but really need some empirical data to parametrize our model. with much help from many patient reviewers of the questions, we finally have a survey ready for operators to fill out. below i'll give an extremely terse description of the model just to give you an idea of why we need this granularity. there are another 10 dense pages describing the model pending peer review at NSF, which i can send to anyone interested in giving us feedback on it. but it's not necessary for responding to the survey. also note the checkbox to indicate you're amenable to further followup questions. survey will be available till 12 april 2012. (or tell us if you want to fill it out but need more time.) survey link, again: http://www.surveygizmo.com/s3/749797/ipv6survey thanks much, k, amogh, emile ------------------------------ Most prior work on modeling the adoption of new technologies assumed a binary decision at the organization level -- in the context of IPv6, this decision means switching completely to IPv6 or not at all. We propose to account for the fact that an organization may deploy IPv6 incrementally in its network, meaning that it will continue to have both IPv4 and IPv6 space. A key aspect of our model is that instead of a binary state per organization, we work at the granularity of devices, which are entities that need to be assigned IP addresses. We consider a device to correspond to a single instance of an IP addressing need, which typically corresponds to an interface. Though there can be multiple interfaces (``devices'') on the same computer/router, and multiple addresses (``virtual interfaces'') on a single interface, we will model each need for an independent IP address as an independent device. We define device classes based on the nature of addresses used to number those devices, e.g., public IPv4, IPv6, dual-stack-NATv4, dual-stack-public-IPv4, etc. We model the network growth requirements of each network in terms of the number of additional devices in that network that need to be configured in one of these device classes. ... (then we catalog a list of costs and incentives associated with the decision to adopt IPv6 or satisfy one's addressing needs with IPv4-based technologies. costs parameters include the costs of IPv4 addresses, NAT deployment, renumbering, and translation between IPv4 and IPv6. we will also try to model incentives such as policies and regulations.) We will then model two separate decision processes for a network, based on whether it seeks to add new devices (to expand its network, provision for new customers, deploy new services, etc.), or whether it seeks to optimize the numbering of its existing devices from among the five device classes defined previously. The latter operation may be necessary if external factors and costs have changed such that the network could substantially lower its costs by numbering its devices differently. We want to structure the model (based on feedback from opsfolk like you) to capture both initial costs as well as ongoing operational costs of supporting a given configuration of devices for a specified window following the decision. Iteration of the decision process continues for each network until we reach a state where no network has the incentive to change the numbering of its devices, which represents the equilibrium. ....

The 18K thing was another operator, but we have not had much luck. I will give my attention to the ticket for now and wait until something happens. Its not a crucial issue since from what I can tell its mostly a cosmetic thing (and a bit of a managerial pain to have to explain the implications to a customer). I have no beef with SORBS, we even rsync their zone on our DNS servers so we can provide faster access to it to our customers that might use it. However recently, getting listing action seems to fall into a void. Cheers, Chris
