Services and Applications

In addition to the SMTP, which is used by the server side (to exchange e-mails between successive e-mail servers or to deliver a message to a client) or by a client (to upload an e-mail), there are other two important protocols widely associated with e-mail service: Post office protocol (POP) [RFC 1225]: This allows a client to receive an e-mail from an e-mail server (download) using authentication. The well-known port of POP version 3 (POPv3) is 110.Internet message access protocol (IMAP) [RFC 2045]: This presents some additional features other than those available with the POP, namely the ability to read e-mails located in a server (through downloading or webmail), while leaving a copy in the mail server. It also allows the share of folders among different users, as well as the search of e-mails in a server. IMAP servers listed on well-known TCP port 143.

E-mail is private communication (person-to-person and person-to-group), so e-mails from the user’s mailbox can not be fetched without the user id, password, and user permission. Several approaches may automatically fetch the e-mails from the user’s mailbox through a third-party application. IMAP service and Gmail API (in the case of Gmail service) are the two main methods for fetching e-mails automatically from the user’s mailbox. In the case of Gmail API, a user must log into Google Cloud Console and enable the Gmail API service. After that, it is necessary to create/select an application under the OAuth Consent Screen of Google Cloud Console. After creating or selecting the existing application, OAuth Client ID credentials are required to create a desktop or web application for getting the Client ID with OAuth credentials as a text or JSON file. After getting the Client ID with OAuth credentials, e-mails from the user’s mailbox can be fetched automatically through programs. The first time, the user will be automatically intimated that “This application wants to access your mailbox – Allow or deny,” and after the user has permission to access the mailbox, e-mails can be fetched. In fetching e-mails using the IMAP service, only a user id and password with some basic settings are required. After Enabling “Allow less secure apps: ON” and Enabling IMAP service in the user’s mailbox, e-mails can be fetched automatically through programs.
Design and implementation of aquaculture resource planning using underwater sensor wireless network

The methodology of Model-View-Controller (MVC) web application model is used to develop the proposed system. Jersey and Thrift is implemented, which accepts calls to get query results from the user and the sensors are deployed at selected site for aquaculture monitoring. An application programmable interface (API) is developed for our aquaculture resources model and connected each other; the external system makes synchronous and asynchronous calls using the service request. Internally, each service talks each other to achieve accuracy for requested query, and also handles specific tasks. An index is used to clone the data while the database connection established between the service and the external system. This includes information such as: Type of Connection used such as MySQL database engine using SQL server authentication, DB schema and the developed application is deployed on Azure platform. The hosted application is can be accessed on www.aquaward.in. The database connection established with application on Azure through, IMAP port 1433 and 80.
An M/G/1 queue with two types of general heterogeneous service and optional repeated service subject to server’s breakdown and delayed repair

Consider a digital communication network system, where mail server transmits the email data from one station to another station. In emailing process, the Mail servers can be broken down into two main categories: outgoing mail servers and incoming mail servers. Outgoing mail servers are known as SMTP, or Simple Mail Transfer Protocol, servers. Incoming mail servers come in two main varieties. POP3, or Post Office Protocol, version 3, servers are best known for storing sent and received messages on PCs’ local hard drives. IMAP, or Internet Message Access Protocol, servers always store copies of messages on servers. After composing a message and hitting send, sender’s email client – whether it’s Outlook Express or Gmail – connects to its domain’s SMTP server. The sender’s email client communicates with the SMTP server, giving it sender’s email address, the recipient’s email address, the message body and any attachments. The SMTP servers process the recipient’s email address – especially its domain and then perform two types of job. In the first type of job it routed the message directly over to the domain’s POP3 or IMAP server, if the domain name is same as the sender’s and in the second type of job the SMTP server send message to the other domain’s server (DNS) if the domain name is different with sender’s. Typically, message processing request arrive at the SMTP server following Poisson stream and message can select any one of the two types of service at the SMTP server (depending upon the choice of the sender, the sender may send message with same or different domain name as recipient’s). The sender can resend the message again due to failure of the previous sending. In practice message processing request may fail due to failure of the SMTP server. After failure of the SMTP server, the server can be repaired. The repair time depends on the degree of failure of the SMTP server. Because the system performance may be heavily affected by SMTP server breakdown, it is well worth to investigate such system from the queueing theory point of view, as well as reliability point of view. In this scenario, the SMTP server, two types of job by SMTP server, message resend correspond to the server, two types of service and repeated service in the queueing terminology.
