    :

    • When you first register, you'll have access to the SES "sandbox" where you can send email only to addresses that you have verified. The verification process sends a confirmation email to the address to be verified; the recipient must click on a link embedded in the email in order to verify the address. You must also verify the email address (or addresses) that will be used to send messages.
    • At this point, with verified addresses in hand, you can send up to 200 messages per day, at a maximum rate of 1 message per second.
    • Once your application is up and running, the next step is to request production access using the SES Production Access Request Form. We'll review your request and generally contact you within 24 hours.
    • Once granted production access, you will no longer have to verify the destination addresses and you'll be able to send email to any address. ... SES will begin to increase your daily sending quota and your maximum send rate based on a number of factors including the amount of email that you send, the number of rejections and bounces that occur, and the number of complaints that it generates. This will occur gradually over time as your activities provide evidence that you are using SES in a responsible manner.

  13. Re:"above best efforts?" on British ISPs Embracing Two-Tier Internet · · Score: 1

    Sorry, I meant to refer to "connectionless" networks, not packet-switched. You obviously can have packets on both types of network.

    Worn out arguments about packet vs circuit switching really have no relevance.

    Nowadays you can oversubscribe circuit switched networks; and you can have packet switched networks with guarantees -- few/nobody might do it, but that doesn't mean it's impossible.

    QoS is about guaranteeing an aggregate service level anyways, not about guaranteeing the delivery of each individual packet, which can die for a multitude of reasons.

    Just like when you try to call someone on the phone, there might not be a free circuit available, the cat might have eaten part of the phone cord, caused a brief short, and then it momentarily came back to normal in the middle of your conversation.

    QoS in this case is about the system dropping other people's ongoing call to free up a circuit for someone who just dialed 911. That doesn't mean the dropped call was not treated with best effort; it's just that there is prioritization and overriding consideration (based on policy).

    Extreme circumstances (such as hardware failures) will cause guarantees not to be met, regardless of technology.

    But aside from those, you can make certain guarantees in regards to packet switched networks, and QoS is a name for the toolbox of things that let you make those (often very limited) guarantees.

  14. Re:"above best efforts?" on British ISPs Embracing Two-Tier Internet · · Score: 1

    This is totally, 100% wrong. "best effort" refers to the fact that in packet-switched networks, there are NO GUARANTEES whether a packet will reach its destination.

    Bzzt... wrong.

    Did it not occur to you that what exactly 'best effort' entails depends on the context in which it is used?

    If you tell your kid you want them to put in their Best Effort to get an A in chemistry; this does not mean you want them to violate rules of the system (such as looking at another student's paper during the test, stealing the answer key, etc).

    When we are talking about QoS, the accepted definition for best effort is noted in RFC2474, RFC 3644

    rfc 2474,

    A "default" PHB MUST be available in a DS-compliant node. This is the common, best-effort forwarding behavior available in existing routers as standardized in [RFC1812]. When no other agreements are in place, it is assumed that packets belong to this aggregate.

    Such packets MAY be sent into a network without adhering to any particular rules and the network will deliver as many of these packets as possible and as soon as possible, subject to other resource policy constraints.

    A reasonable implementation of this PHB would be a queueing discipline that sends packets of this aggregate whenever the output link is not required to satisfy another PHB. A reasonable policy for constructing services would ensure that the aggregate was not "starved". This could be enforced by a mechanism in each node that reserves some minimal resources (e.g, buffers, bandwidth) for Default behavior aggregates. This permits senders that are not differentiated services-aware to continue to use the network in the same manner as today. The impact of the introduction of differentiated services into a domain on the service expectations of its customers and peers is a complex matter involving policy decisions by the domain and is outside the scope of this document. The RECOMMENDED codepoint for the Default PHB is the bit pattern ' 000000'; the value '000000' MUST map to a PHB that meets these specifications. The codepoint chosen for Default behavior is compatible with existing practice [RFC791]. Where a codepoint is not mapped to a standardized or local use PHB, it SHOULD be mapped to the Default PHB.

    A packet initially marked for the Default behavior MAY be re-marked with another codepoint as it passes a boundary into a DS domain so that it will be forwarded using a different PHB within that domain, possibly subject to some negotiated agreement between the peering domains.

    That doesn't make any sense. If they are really making their best effort, it would be the same as guaranteed priority.

    You're missing the point. These are accepted industry terms, not subject to dispute by people who think they know something about computer networking. Suggesting there is something wrong with the terms is just equivalent to brandishing your own errors/lack of understanding:

    Quality of services clases impose constraints on the system, by assigning traffic to different queues with different sizes and latency/drop preferences. The priority queues are constraints, and not to be violated in order to deliver a packet. They are usually of a fixed size, so even some packets from prioritized streams can wind up dropped into lower priority classes.

    Best effort refers to the best effort to deliver packets in that class, without violating any constraints imposed on the system.

    Priority queues are constraints; packets in a higher priority queue cannot be dropped at a higher rate than allowed, for the purpose of delivering best effort packets.

    Best effort is basically near the very bottom. The only worse traffic class is called Less than best effort; typically applied to non-drop non-latency sensitive traffic such as bulk transfers, e.g. FTP, FXP, SMB, Peer to Peer networks, sometimes SMTP.

    Except for the fact that it doesn't make any sense. How can it be the "best effort" if something can be prioritised ahead of it?

    It makes perfect sense. When a QoS scheme is being designed; traffic is divided into classes, and (typically) each class is assigned to queues based on priority; each queue has a certain size.

    The class that is not associated with any priority queue at all is called "best effort". The reason it is called best effort, is, unlike other traffic classes -- there is no priority or reservation.

    Other traffic has priority in the form of something close to a guarantee; meaning, if prioritized traffic does not exceed the size of the priority queue, it is guaranteed to be delivered even in the face of congestion. Whereas the remaining traffic is just "best effort".

    The traffic that is best effort will be delivered if possible (in the face of congestion), but it might be dropped, best effort is weaker than guaranteed priority.
