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 this is not possible, this 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. 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 . ESMTP requires a single status for the entire message body. LMTP requires a response for each previously successful RCPT command. That is, in case of multiple recipients, after the body of the message has been transmitted, LMTP can still fail for some recipient ... mail protocols de Local Mail Transfer Protocol es LMTP lv LMTP pt Local Mail Transfer Protocol ... deliverable to its final destination.

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 .

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 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. However, this is much preferable to a shorter buffer, which would result in ignored dropped packets, which in turn would result in much longer overall transmission times. During network congestion , queuing delays can be considered infinite when the packet is dropped. The retransmission of such packets causes significant overall delay because all forms of delay will be incurred more than once. If the network congestion continues, the packet may be dropped many times. Many protocols, such as Transmission Control Protocol TCP , will throttle back their sending and wait for the network to clear up. While taking about Queuing in wireless communication its an important tool for handoff as it decreases the probability of forced termination of a call due to unavailable voice channels in a base station.the basic theory is there is a time delay between the threshold level of signal required for handoff and minimum ... over to the free voice channel.

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 www.rfc archive.org getrfc.php?rfc 970 On packet switches with infinite storage, Request for Comments RFC 970, IETF ...

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 turns 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.

Microsoft Message Queuing or MSMQ is a Message Queue implementation developed by Microsoft and deployed in its Microsoft Windows Windows Server operating systems since Windows NT 4 and Windows 95 . The latest Windows 7 also includes this component. In addition to its mainstream server platform support, MSMQ has been incorporated into Microsoft Embedded platforms since 1999 and the release of Windows CE 3.0. ref cite web url http msdn.microsoft.com en us library ms834460.aspx title Microsoft Windows CE 3.0 Message Queuing Service accessdate 2009 11 25 publisher Microsoft Developer Network ref Overview MSMQ is essentially a messaging protocol that allows applications running on separate servers processes to communicate in a failsafe manner. A queue is a temporary storage location from which messages can be sent and received reliably, as and when conditions permit. This enables communication across heterogeneous networks and between computers which may not always be connected. By contrast, Internet socket sockets and other network protocols assume that direct connections always exist.

orphan date August 2009 Credit based fair queuing is a computationally efficient alternative to fair queueing . Credit is accumulated to queues as they wait for service. Credit is spent by queues while they are being serviced. Queues with positive credit are eligible for service. The rate of credit accumulation and release can be adjusted on a queue by queue basis to produce a weighted queuing behavior.

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 .

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. Contrary to FQ, WFQ allows different sessions to have different service shares.
