unreferenced date August 2008 The Simple Mail Access Protocol SMAP is an application layer Internet protocol computing protocol for accessing e mail stored on a Server computing server . It was introduced as part of the Courier Mail Server Courier software suite suite , with the goal of creating a simpler and more capable alternative to Internet Message Access Protocol IMAP . Notable features of SMAP MIME E mail attachment attachments can be transmitted in their raw, decoded form. This allows large base64 encoded attachments to be transmitted without the 4 3 inflation that base64 encoding usually incurs. Support for sending outgoing e mails through the SMAP connection, instead of using a separate SMTP connection to the server. An outgoing message only needs to be transmitted once to send it, and save a copy to a server side folder. Unicode folder names, with native support for hierarchy. SMAP clients and servers can fall back to IMAP if the peer does not support SMAP. As of 2005 , SMAP is still considered experimental, and is only supported by the Courier Mail Server Courier server and Cone software Cone E mail client client .

The Local Mail Transfer Protocol LMTP is a derivative of ESMTP , the extension of the Simple Mail Transfer Protocol . It is defined in RFC 2033. ref RFC 2033, The Local Mail Transfer Protocol , J. Myers, The Internet Society October 1996 ref LMTP is designed as an alternative to normal SMTP for situations where the receiving side does not have a mail queue, such as a Message transfer agent mail storage server acting as a Mail Delivery Agent . Mail queues are an inherent requisite of SMTP. In situations in which mail queues are not possible, LMTP is desirable, since a mail storage server should manage only its mail store without having to allocate more storage for a mail queue. This is not possible with SMTP when there are multiple recipients for a mail message. SMTP can only indicate successful delivery or failure for all or none of the recipients, creating the need for a separate queue to handle the failed recipients. LMTP, on the other hand, can indicate success or failure to the client for each recipient, allowing the client to handle the queueing instead. The client in this case would typically be an Internet facing mail gateway. LMTP is not intended for use over wide area network s. In other words, the MTA still handles all outgoing mail, including the mail stream from the LMTP agent, to another mail server located somewhere on the Internet. LMTP is an Application Layer protocol of the Internet Protocol Suite . It uses a Transmission Control Protocol TCP transport like SMTP, but must not use port number 25, the well known port for SMTP. LMTP conversation syntax is based on the same commands as Extended SMTP with the following exceptions ESMTP s EHLO verb is replaced with LHLO ... to its final destination. This removes the need for a mail queue. For this reason, LMTP is not run on the standard TCP port of SMTP.

In telecommunication and computer engineering , the queuing delay or queueing delay is the time a job waits in a Queue data structure queue until it can be executed. It is a key component of network delay . This term is most often used in reference to router computing router s. When Packet information technology packet s arrive at a router, they have to be processed and transmitted. A router can only process one packet at a time. If packets arrive faster than the router can process them such as in a burst transmission the router puts them into the queue also called the Buffer computer science buffer until it can get around to transmitting them. The maximum queuing delay is proportional to buffer size. The longer the line of packets waiting to be transmitted, the longer the average waiting time is and when the buffer fills the router must drop packets. When the transmission protocol uses the dropped packets symptom of filled buffers to regulate its transmit rate, as the Internet s TCP does, bandwidth is fairly shared at near theoretical capacity with minimal network congestion delays. Absent this feedback mechanism the delays become both unpredictable and rise sharply, a symptom also seen as freeways approach capacity metered onramps are the most effective solution there, just as TCP s self regulation is the most effective solution when the traffic is packets instead of cars . This result is both hard to model mathematically and quite counterintuitive to people who lack experience with mathematics or real networks. Failing to drop packets, choosing instead to buffer an ever increasing number of them, produces bufferbloat . In Kendall s notation , the M M 1 K queuing model, where K is the size of the buffer, may be used to analyze the queuing delay in a specific system.

Fair queuing is a scheduling algorithm used in computer networks computer and telecommunications network s to allow multiple flow computer networking packet flows to fairly share the link capacity. The advantage over conventional first in first out FIFO queuing is that a high bit rate data rate flow, consisting of large or many packet information technology data packet s, cannot take more than its fair share of the link capacity. Fair queuing can be interpreted as a packet approximation of generalized processor sharing GPS . It was proposed by John Nagle in 1985 ref John Nagle http tools.ietf.org html rfc970 On packet switches with infinite storage, Request for Comments RFC 970, IETF , December ... queuing is used in routers, switches, and statistical multiplexer s that forward packets from a buffer computer science buffer .

Orphan date February 2009 Tagged queuing is a method for allowing a Computer hardware hardware device or Controller computing controller to process commands received from a device driver out of order. It requires that the device driver attaches a tag to each command which the controller or device can later use to identify the response to the command. Tagged queueing can speed up processing considerably if a controller serves devices of very different speeds, such as an SCSI controller serving a mix of CD ROM drives and high speed Disk storage disks . In such cases if a request to fetch data from the CD ROM is shortly followed by a request to read from the disk, the controller doesn t have to wait for the CD ROM to fetch the data, it can instead instruct the disk to fetch the data and return the value to the device driver, while the CD ROM is probably still seeking.

Orphan date July 2010 Low Latency Queuing LLQ is a feature developed by Cisco Systems Cisco to bring strict priority queuing PQ to Class Based Weighted Fair Queuing CBWFQ . LLQ allows delay sensitive data such as voice to be given preferential treatment over other traffic by letting the data to be dequeued and sent first. ref http www.cisco.com en US docs ios 12 0t 12 0t7 feature guide pqcbwfq.html Low Latency Queueing , Cisco IOS Software Releases 12.0 T ref Development Class based weighted fair queuing CB WFQ was initially released without the support of a priority queuing system, thus it could not guarantee the delay and jitter delay variation requirements of real time, interactive voice and video conversations. Since for CBWFQ, the weight for a packet belonging to a specific class is derived from the bandwidth assigned to the class, which in turn determines the order in which packets are sent. All packets are serviced fairly based on weight and no class of packets may be granted strict priority. This scheme poses problems for voice traffic that is largely intolerant of delay, especially variation in delay. In order to address this, Cisco released LLQ to provide strict priority queuing for CBWFQ by enabling the use of a single, strict priority queue within CBWFQ at the class level. This allows for directing traffic belonging to a class to the CBWFQ strict priority queue. One or more classes priority status can be given within a policy map. When multiple classes within a single policy map are configured as priority classes, all traffic from these classes is enqueued to the same single, strict priority queue.

merge to Command queuing date January 2012 Image NCQ.svg thumb 300px right NCQ allows the drive itself to determine the optimal order in which to retrieve outstanding requests. This may, as here, allow the drive to fulfill all requests in fewer rotations and thus less time. In computing , Native Command Queuing NCQ is an extension of the Serial ATA protocol allowing hard disk drive s to internally optimize the order in which received read and write commands are executed. This can reduce the amount of unnecessary drive head movement, resulting in increased performance and slightly decreased wear of the drive for workloads where multiple simultaneous read write requests are outstanding, most often occurring in Server computing server type applications. History Native Command Queuing was preceded by Parallel ATA s version of Tagged Command Queuing TCQ . ATA s attempt at integrating TCQ was constrained by the requirement that ATA host bus adapters use Industry Standard Architecture ISA bus device protocols to interact with the operating system. The resulting high CPU overhead and negligible performance gain contributed to a lack of market acceptance for TCQ. NCQ differs from TCQ in that, with NCQ, each command is of equal importance, but NCQ s host bus adapter also programs its own first party Direct memory access DMA engine with CPU given DMA parameters during its command sequence ... support SATA NCQ increases this to over 14,000 IOPS on the same basis.

Weighted fair queuing WFQ is a data packet scheduling computing scheduling technique allowing different scheduling priorities to statistical multiplexing statistically multiplexed data Flow computer networking flows . WFQ is a generalization of fair queuing FQ . Both in WFQ and FQ, each data flow has a separate FIFO queue. In FQ, with a link data rate of math R math , at any given time the math N math active data flows the ones with non empty queues are serviced simultaneously, each at an average data rate of math R N math . Since each data flow has its own queue, an ill behaved flow who has sent larger packets or more packets per second than the others since it became active will only punish itself and not other sessions. As opposed to FQ, WFQ allows different sessions to have different service shares.
