Description

METHOD AND SYSTEM FOR MANAGING CONNECTIONS AT HYPERTEXT TRANSFER PROTOCOL (HTTP) CLIENT FIELD OF THE DISCLOSURE [0001] The present disclosure relates generally to the field of wireless communication systems. More particularly, the present disclosure relates to methods and systems for managing connections at Hypertext Transfer Protocol (HTTP) Client to increase overall throughput of overall communication network. BACKGROUND [0002] The following description of related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of prior art. [0003] Wireless communication technology has rapidly evolved over the past few decades, with each generation bringing significant improvements and advancements. The first generation of wireless communication technology was based on analog technology and offered only voice services. However, with the advent of the second-generation (2G) technology, digital communication and data services became possible, and text messaging was introduced. 3G technology marked the introduction of high-speed internet access, mobile video calling, and location-based services. The fourth-generation (4G) technology revolutionized wireless communication with faster data speeds, better network coverage, and improved security. Currently, the fifth-generation (5G) technology is being deployed, promising even faster data speeds, low latency, and the ability to connect multiple devices simultaneously. With each generation, wireless communication technology has become more advanced, sophisticated, and capable of delivering more services to its users. [0004] In a communication network, Hypertext Transfer Protocol (HTTP) Client uses multiple connections, rather than a single connection, in order to complete communication efficiently. Using a single connection for communication allows only one outstanding request for a peer which creates significant overhead, and slowing down the application which in turn, causes ripple effect on other dependent applications. Using multiple but limited number of connections solves this problem. However, use of multiple connections has its own disadvantages. [0005] One such issue is idle connections. When no communication is taking place between a client and a server but a connection persists between them, an idle connection occurs. While multiple connections may be added to cater to requests when the load is high, these connections remain in the idle state when the load reduces. [0006] Further, in the existing solutions where an idle connection take place, a wait-timer for a pre-defined period of time is used at the server end to monitor if communication is taking place or not. However, when the idle connection occurs and no communication takes place within such pre-defined period of time, activation of firewalls take place to break the connection from the server end. After the idle wait time, the firewalls (if any exists between HTTP client and server) tear-down the underlying transport layer connection without letting the client know. This leads to the formation of a stale state (or idle state), i.e. the connection can no longer be used to send requests to the server and the connection’s state at the client’s end shall always be stale. This also leads to inefficient usage of the resources. [0007] Further, over the period of time various solutions have been developed to improve the performance of communication devices and to enhance HTTP client to efficiently use multiple connections to increase overall throughput of overall communication network. However, there are certain challenges with existing solutions such increased overall time for communication due to formation of a new connection for every request for communication, and occurrence of stale connection when an idle state for a connection occurs for more than the pre-defined period. [0008] Thus, there exists an imperative need in the art to managing connections at Hypertext Transfer Protocol (HTTP) Client for enhancing HTTP client to efficiently use multiple connections to increase overall throughput of overall communication network, which the present disclosure aims to address. OBJECTS OF THE INVENTION [0009] Some of the objects of the present disclosure, which at least one embodiment disclosed herein satisfies are listed herein below. [0010] It is an object of the present disclosure to provide a system and a method for managing connections at Hypertext Transfer Protocol (HTTP) Client. [0011] It is another object of the present disclosure to provide a system and a method for enhancing HTTP client to efficiently use multiple connections to increase overall throughput of overall communication network. [0012] It is yet another object of the present disclosure to provide a solution that provides a persistent connection for enhancing HTTP communication. [0013] It is yet another object of the present disclosure to provide a time-efficient solution to use multiple connections in HTTP communication. [0014] It is yet another object of the present disclosure to provide a solution in which a custom HTTP client can adjust the number of connections as per requirement of the application. [0015] It is yet another object of the present disclosure to provide a solution in which a custom HTTP client can detect stale (idle) connections which have been closed by the server but their closure event was undetected at the client. Upon detection, it can retry the failed requests over new connections.

While specific embodiments may disclose a particular functionality of these units for clarity, it is recognized that various configurations and combinations thereof are within the scope of the disclosure. The functionality of specific units as disclosed in the disclosure should not be construed as limiting the scope of the present disclosure. Consequently, alternative arrangements and substitutions of units, provided they achieve the intended functionality described herein, are considered to be encompassed within the scope of the present disclosure. [0045] As discussed in the background section, the current known solutions for enhancing HTTP client to efficiently use multiple connections to increase overall throughput of overall communication network have several shortcomings such as increased overall time for communication due to formation of a new connection for every request for communication, and occurrence of state when an idle connection occurs for more than the pre-defined period. [0046] The present disclosure aims to overcome the above-mentioned and other existing problems in this field of technology by allowing the network to make persistent connections to ensure that the teardown of the connection does not take place once the request for the connection has been met with response. Further, HTTP client can adjust and maintain the number of connections based on the requirement of the application. Furthermore, the HTTP client can detect stale state for the idle connections that have been closed by the server but their closure event was left undetected at the client. Upon detection of the stale state for the idle connection (that is, upon detection of stale (or idle) connection for a threshold period of time), HTTP client retries to send requests to form new connections in order to allow the communication to happen smoothly whenever the communication is performed within such connection. Moreover, the HTTP Client also supports secure communication. [0047] In the present disclosure, the number of connections to be created with the server by the HTTP client are pre-configured and these connections are maintained (created or destroyed) as per the demand of the application by calculating the current load being generated by the application. Also, the HTTP Client detects the stale connection when it receives Reset (RST) at Transport Protocol (TCP) level from the peer while sending request, wherein the server or the peer is pre-configured with Fully Qualified Domain Name (FQDN) and Internet Protocol (IP) addresses of active and standby IP addresses. This happens when there is firewall between Client and Server. Server closes the connections with the firewall but connections between client and firewall remained intact. Upon stale connection detection, new connection(s) is(are) established with the peer for request forwarding. [0048] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings. [0049] Fig. 1 illustrates an exemplary block diagram representation of a Hypertext Transfer Protocol (HTTP) client-server interface architecture [102]. A client [102a] communicates with server [102b] using the HTTP interface [102c]. The client–server model is a distributed application structure that distributes tasks between the providers of a resource, called servers, and service requesters, called clients. The clients [102a] and servers [102b] communicate over a computer network on separate hardware, but both client [102a] and server [102b] may reside in the same system. A server host runs one or more server programs, which share their resources with clients. The clients [102a] and servers [102b] exchange messages in a request–response messaging pattern. In operation for communication between clients [102a] and servers [102b], server(s) [102b] waits for client(s) [102a] request messages. After the server [102b] receives a request message from a client [102a], the server [102b] processes the message, and replies to the client [102a] with a response message. All the communication takes place using the Hypertext Transfer Protocol. The response may contain an HTTP Response status code indicating whether or not the request succeeded. [0050] Fig.2 illustrates an exemplary block diagram of a computing device [1000] (or as used herein, computer system [1000]) upon which the features of the present disclosure may be implemented in accordance with exemplary implementation of the present disclosure. In an implementation, the computing device [1000] may also implement a method for managing connections at Hypertext Transfer Protocol (HTTP) Client to increase overall throughput of overall communication network utilising the system. In another implementation, the computing device [1000] itself implements the method for managing connections at Hypertext Transfer Protocol (HTTP) Client to increase overall throughput of overall communication network using one or more units configured within the computing device [1000], wherein said one or more units are capable of implementing the features as disclosed in the present disclosure. [0051] The computing device [1000] may include a bus [1002] or other communication mechanism for communicating information, and a hardware processor [1004] coupled with bus [1002] for processing information. The hardware processor [1004] may be, for example, a general purpose microprocessor. The computer system [1000] may also include a main memory [1006], such as a random access memory (RAM), or other dynamic storage device, coupled to the bus [1002] for storing information and instructions to be executed by the processor [1004]. The main memory [1006] also may be used for storing temporary variables or other intermediate information during execution of the instructions to be executed by the processor [1004]. Such instructions, when stored in non-transitory storage media accessible to the processor [1004], render the computer system [1000] into a special-purpose machine that is customized to perform the operations specified in the instructions. The computer system [1000] further includes a read only memory (ROM) [1008] or other static storage device coupled to the bus [1002] for storing static information and instructions for the processor [1004]. [0052] A storage device [1010], such as a magnetic disk, optical disk, or solid-state drive is provided and coupled to the bus [1002] for storing information and instructions. The computer system [1000] may be coupled via the bus [1002] to a display [1012], such as a cathode ray tube (CRT), Liquid crystal Display (LCD), Light Emitting Diode (LED) display, Organic LED (OLED) display, etc. for displaying information to a computer user. An input device [1014], including alphanumeric and other keys, touch screen input means, etc. may be coupled to the bus [1002] for communicating information and command selections to the processor [1004]. Another type of user input device may be a cursor controller [1016], such as a mouse, a trackball, or cursor direction keys, for communicating direction information and command selections to the processor [1004], and for controlling cursor movement on the display [1012]. This input device typically has two degrees of freedom in two axes, a first axis (e.g., x) and a second axis (e.g., y), that allow the device to specify positions in a plane. [0053] The computer system [1000] / computing device [1000] may implement the techniques described herein using customized hard-wired logic, one or more ASICs or FPGAs, firmware and/or program logic which in combination with the computer system [1000] causes or programs the computer system [1000] to be a special-purpose machine. According to one implementation, the techniques herein are performed by the computer system [1000] in response to the processor [1004] executing one or more sequences of one or more instructions contained in the main memory [1006]. Such instructions may be read into the main memory [1006] from another storage medium, such as the storage device [1010]. Execution of the sequences of instructions contained in the main memory [1006] causes the processor [1004] to perform the process steps described herein. In alternative implementations of the present disclosure, hard-wired circuitry may be used in place of or in combination with software instructions. [0054] The computer system [1000] also may include a communication interface [1018] coupled to the bus [1002]. The communication interface [1018] provides a two-way data communication coupling to a network link [1020] that is connected to a local network [1022]. For example, the communication interface [1018] may be an integrated services digital network (ISDN) card, cable modem, satellite modem, or a modem to provide a data communication connection to a corresponding type of telephone line. As another example, the communication interface [1018] may be a local area network (LAN) card to provide a data communication connection to a compatible LAN. Wireless links may also be implemented. In any such implementation, the communication interface [1018] sends and receives electrical, electromagnetic or optical signals that carry digital data streams representing various types of information. [0055] The computer system [1000] can send messages and receive data, including program code, through the network(s), the network link [1020] and the communication interface [1018]. In the Internet example, a server [1030] might transmit a requested code for an application program through the Internet [1028], the ISP [1026], the local network [1022], host [1024] and the communication interface [1018]. The received code may be executed by the processor [1004] as it is received, and/or stored in the storage device [1010], or other non-volatile storage for later execution. [0056] Referring to Figure 3, an exemplary block diagram of a system [300] for managing connections at Hypertext Transfer Protocol (HTTP) Client to increase overall throughput of overall communication network is shown, in accordance with the exemplary implementations of the present disclosure. The system [300] comprises at least one connection establishing unit [302], at least one creating unit [304], at least one receiving unit [306], at least one queueing unit [308], at least one identifying unit [310], and at least one detecting unit [312], at least one peer management task (PMT) unit [314] (or PMT module [314], and at least one transmitting unit [316]. Also, all of the components/ units of the system [300] are assumed to be connected to each other unless otherwise indicated below. As shown in the figures all units shown within the system should also be assumed to be connected to each other. Also, in Fig.3 only a few units are shown, however, the system [300] may comprise multiple such units or the system [300] may comprise any such numbers of said units, as required to implement the features of the present disclosure. Further, in an implementation, the system [300] may be present in a user device to implement the features of the present disclosure. The system [300] may be a part of the user device / or may be independent of but in communication with the user device (may also referred herein as a UE). In another implementation, the system [300] may reside in a server or a network entity. In yet another implementation, the system [300] may reside partly in the server/ network entity and partly in the user device. [0057] The system [300] is configured for managing connections at Hypertext Transfer Protocol (HTTP) Client, with the help of the interconnection between the components/units of the system [300]. [0058] The configuration of a HTTP Server(s) is done prior to establishment of the connections between the HTTP client and the HTTP servers. In this, multiple servers and/or peers may be configured. Both active and standby peers are configured and mapped to a fully qualified domain name (FQDN). Further, a data storing the FQDN as a key and using active and standby peers as value is used. This data may be pre-stored in a storage unit [318]. Once the configuration is done, and is successful, the client may initiate the configured number of connections towards the server. For this purpose, the client may use the connection establishing unit [302]. The connection establishing unit [302] is configured to establish one or more connections with one or more servers. [0059] Further, the creating unit [304] is configured to create a queue for each of the one or more connections with the one or more servers, wherein the queue acts as a buffer for one or more queries awaiting transmission to the one or more servers. For each server/peer configured, the creating unit [304] may create a new queue. Also, in an implementation, a new request may be added to the queue every time when the new request to be sent to the server/peer is submitted. In other words, when an application submits a request through client, requests are buffered in a queue. Also, a Peer Management Task (PMT) module (or as used herein, PMT unit [314]) is made to run in the background. This PMT module constantly monitors for receival of any new request that is submitted to a queue. In an implementation, the PMT module is notified to process further the newly received request. The PMT module may find an available resource to be used for further processing of the request(s). [0060] Thus, after creation of the queue, the receiving unit [306] is configured to receive the one or more queries from an application program interface (API) for the one or more servers. For this purpose, an application module may call an Application Programming Interface (API) of the client to send a request. This API has a Universal Resource Identifier (URI) as one of the parameters. The application module can provide the FQDN or internet protocol (IP) address as values of the URI to send such requests. [0061] Further, queueing unit [308] is configured to add the one or more queries in the respective queue for the one or more servers. Pertinently, if the FQDN is used by the application module in the above request, an available connection of active instance may be preferred over that of standby instance. However, if the IP address is used in URI, the request may be routed to the specific instance, be it an active instance or a standby instance. Also, after submitting the request, application module is free from further processing, which will facilitate in increasing overall throughput of overall communication network. [0062] Further, the identifying unit [310] is configured to identify an available connection with the one or more servers. For this purpose, the identifying unit [310] may determine whether connection is available or not. If it is determined that a connection is available, then the request may be written on the available connection. However, in an implementation, if it is determined that no connection is available, then the identifying unit [310] may further determine if the number of connections exceed a pre-configured threshold number of connections. Further, if it is determined that the number of connections do not exceed the pre-configured threshold number of connections, then a new connection may be created for writing the request on the newly created connection. However, if it is determined that the number of connections exceed the pre-configured threshold number of connections, then the system waits for a connection be to free and when the connection becomes available, then the request may be written on the available connection. In an implementation, once the PMT module is notified, the request from the queue is popped out, and identification of an available connection from the pool is done or a new connection is created. Further, the request is forwarded to such identified or created connection. Also, in an implementation, if the writing of the request is successful, then a connection is formed and the flow is terminated. However, if the writing of the request in unsuccessful, then this connection is closed, and a new connection is created. Further, the request is written over the new connection created. Once, the writing of this new request is successful, then it is checked by the detecting unit [312] if there is any problem occurring while forwarding the request to the server. If a problem is detected, by the detecting unit [312], while forwarding the request to the server, a failure reason is checked. A person skilled in the art would appreciate that in a network, there are regular connection fluctuations (connections being created and destroyed), so there are occasions where the connection seems available but when an application try to write a request on that connection, the connection may become unavailable. Further, in scenarios where a firewall is present in the path of a data packet, idle connections may frequently be closed by the firewall. A stateful firewall (that keeps a track of the state or context of connections by maintaining a state table, as opposed to stateless firewalls that do not track the state of connections) may remove connections from its state table after a given idle session timeout. Due to this, a client may be unaware of the connection closure at firewall end. Due to this, the connection appears active at the client end. The client end gets to know about this connection closure when an application tries to write a request over the channel and it receives CONNECTION_RESET indication from the firewall. Thus, if the failure is due to CONNECTION_RESET, then the identifying unit [310] marks/identifies the available connection as a stale connection. Further, in this implementation, the queueing unit [308] closes this identified stale connection. [0063] In another exemplary implementation, after closing the identified stale connection, a new connection may also be created to maintain the connection pool. Further, in this implementation, the connection establishing unit [302] may establish a new connection with the one or more servers, wherein the added one or more queries may be transmitted over this new connection. [0064] In other words, in an event the PMT unit [314] identifies that no connection is available, the PMT unit [314] is further configured to determine whether a number of connections exceeds a preconfigured number of connections, that is a threshold number of connections. This threshold number of connections is decided as per the throughput requirement of the application. Higher connections will lead to higher throughput. However, greater number of connections than required may lead to resource wastage. Hence, the threshold number of connections are configured by the application basis at least the throughput requirement of the application. Also, in an exemplary implementation, the one or more HTTP clients establish a preconfigured number of connections with the one or more servers. Further, in an exemplary implementation, in an event the PMT unit [314] identifies that the number of connections is less than the preconfigured number of connections, the creating unit [304] may create a new connection with the one or more servers. In this implementation, the transmitting unit [316] may be further configured to transmit the added one or more queries to the one or more servers over the new connection. [0065] Also, in this implementation, in an event the PMT unit [314] identifies that the number of connections exceeds the preconfigured number of connections, the queueing unit [308] is further configured to wait for the one or more connections with the one or more servers to become available. In this implementation, the transmitting unit [316] is further configured to transmit the added one or more queries to the one or more servers once the one or more connections are available. [0066] In an exemplary implementation, the one or more queries comprises HTTP requests corresponding to at least one of GET, POST, PUT, DELETE, or other standard HTTP methods intended for communication with the one or more servers. [0067] The system [300] allows multiple connection requests to be sent asynchronously to increase the overall throughput of the application. Further, the system allows the use of multiple connections to be optimized in a way such that these connections are created and teared down depending on the traffic currently being generated for proper resource utilization. Furthermore, more connections are created (subjected to a threshold) if the application requires and connections are teared down when application requires only a few. Thereby, traffic handling during both the peak hours and lean hours is taken care of effectively. Further, the problem of stale connections due to the idle state is also solved. When the client tries to send a request over the stale connection due to idle state, it receives RST (reset) frame indicating CONNECTION_RESET over TCP (Transmission Control Protocol) from peer. Upon receiving the RST packet, the client releases the connection state from its memory and frees the unusable resource and works upon creation of a new connection (if required) with the peer. [0068] Referring to Figure 4, an exemplary method flow diagram [400], for enhancing HTTP client to efficiently use multiple connections to increase overall throughput of overall communication network, in accordance with exemplary embodiments of the present invention is shown. In an implementation the method [400] is performed by the system [300]. As shown in Figure 4, the method [400] starts at step [302]. For the purpose of clarity, various components as shown in Figure 3 may be used to explain the steps of Figure 4. Also, for the purpose of clarity, components of Figure 5 which illustrates a method flow diagram of an exemplary process indicating an exemplary scenario of the process for managing connections at Hypertext Transfer Protocol (HTTP) Client to increase overall throughput of overall communication network, in accordance with exemplary embodiments of the present disclosure, may also be used in conjunction with the explanation of Figure 4 in this disclosure. [0069] At step [402], the method [400] as disclosed by the present disclosure comprises establishing, by the connection establishing unit [302], one or more connections with one or more servers. The connection establishing unit [302] establishes one or more connections with the one or more servers as per pre-configurations or based on the demand of the application by calculating the current load being generated by the application. Also, a configuration of a HTTP Server(s) is done prior to establishment of the connections between the HTTP client and the HTTP servers (See block 501 of Fig. 5). In this, multiple servers and/or peers may be configured. Both active and standby peers are configured and mapped to a fully qualified domain name (FQDN). Further, a data storing the FQDN as a key and using active and standby peers as value is used. This data may be pre-stored in a storage unit [318]. Once the configuration is done, and is successful, the client may initiate the configured number of connections towards the server. For this purpose, the client may use the connection establishing unit [302]. [0070] Next, at step [404], the method [400] as disclosed by the present disclosure comprises creating, by the creating unit [304], a queue for each of the one or more connections with the one or more servers. For each server/peer configured, the creating unit [304] may create a new queue (See block 502 of Fig. 5). Also, in an implementation, a new request may be added to the queue every time when the new request to be sent to the server/peer is submitted. In other words, when an application submits a request through client, requests are buffered in a queue. Also, a Peer Management Task (PMT) module (or as used herein, PMT unit [314]) is made to run in the background. This PMT unit [314] constantly monitors for receival of any new request that is submitted to a queue. In an implementation, the PMT unit [314]is notified to process further the newly received request. The PMT unit [314] may find an available resource to be used for further processing of the request(s). [0071] Next, after creation of the queue, at step [406], the method [400] as disclosed by the present disclosure comprises receiving, by the receiving unit [306], one or more queries from an application program interface (API) for the one or more servers. For this purpose, an application module may call an Application Programming Interface (API) of the client to send a request (See block 503 of Fig.5). This API has a Universal Resource Identifier (URI) as one of the parameters. The application module can provide the FQDN or internet protocol (IP) address as values of the URI to send such requests. [0072] Next, at step [408], the method [400] as disclosed by the present disclosure comprises adding, by the queueing unit [308], the one or more queries in the respective queue for the one or more servers (See block 504 of Fig.5). Pertinently, if the FQDN is used by the application module in the above request, an available connection of active instance may be preferred over that of standby instance. However, if the IP address is used in URI, the request may be routed to the specific instance, be it an active instance or a standby instance. Also, after submitting the request, application module is free from further processing, which will facilitate in increasing overall throughput of overall communication network. [0073] Next, at step [410], the method [400] as disclosed by the present disclosure comprises identifying, by the identifying unit [310], an available connection with the one or more servers. For this purpose, the identifying unit [310] may determine whether connection is available or not (See block 505 of Fig.5). If it is determined that a connection is available, then the system proceeds to the next step of writing the request on the available connection (See block 508 of Fig. 5). However, in an implementation, if it is determined that no connection is available, then the identifying unit [310] may further determine if the number of connections exceed a pre-configured threshold number of connections (See block 506 of Fig. 5). Further, if it is determined that the number of connections do not exceed the pre-configured threshold number of connections, then the method proceeds to creating a new connection (See block 509 of Fig.5) and then the method moves to the next step of writing the request on the available connection (See block 508 of Fig. 5). However, if it is determined that the number of connections exceed the pre-configured threshold number of connections, then the system waits for a connection be to free (See block 507 of Fig.5) and when the connection becomes available, the method moves to the next step of writing the request on the available connection (See block 508 of Fig.5). In an implementation, once the PMT module is notified, the request from the queue is popped out, and identification of an available connection from the pool is done or a new connection is created. Further, the request is forwarded to such identified or created connection. Also, in an implementation, it is checked whether the writing of the request is successful or not (See block 510 of Fig.5). If the writing of the request is successful, then a connection is formed and the flow is terminated (See block 514 of Fig. 5). However, if the writing of the request in unsuccessful, then this connection is closed (See block 511 of Fig. 5), and a new connection is created (See block 512 of Fig. 5). Further, the request is written over the new connection created (See block 513 of Fig.5). [0074] In an implementation, once the writing of this new request is successful, then the method comprises checking, by the detecting unit [312], if there is any problem occurring while forwarding the request to the server. If a problem is detected, by the detecting unit [312], while forwarding the request to the server, a failure reason is checked. A person skilled in the art would appreciate that in a network, there are regular connection fluctuations (connections being created and destroyed), so there are occasions where the connection seems available but when an application try to write a request on that connection, the connection may become unavailable. Further, in scenarios where a firewall is present in the path of a data packet, idle connections may frequently be closed by the firewall. A stateful firewall (that keeps a track of the state or context of connections by maintaining a state table, as opposed to stateless firewalls that do not track the state of connections) may remove connections from its state table after a given idle session timeout. Due to this, a client may be unaware of the connection closure at firewall end. Due to this, the connection appears active at the client end. The client end gets to know about this connection closure when an application tries to write a request over the channel and it receives CONNECTION_RESET indication from the firewall. Thus, if the failure is due to CONNECTION_RESET, then the method comprises identifying/marking, by the identifying unit [310], the available connection as a stale connection. Further, in this implementation, the method may further comprise closing, by the queueing unit [308], this identified stale connection. In another exemplary implementation, after closing the identified stale connection, a new connection may also be created to maintain the connection pool. Further, in this implementation, the method may further comprise, establishing, by the connection establishing unit [302], a new connection with the one or more servers, wherein the added one or more queries may be transmitted over this new connection. [0075] In other words, in an event the PMT unit [314] identifies that no connection is available, the PMT unit [314] determines whether a number of connections exceeds a preconfigured number of connections, that is a threshold number of connections. This threshold number of connections is decided as per the throughput requirement of the application. Higher connections will lead to higher throughput. However, greater number of connections than required may lead to resource wastage. Hence, the threshold number of connections are configured by the application basis at least the throughput requirement of the application. Also, in an exemplary implementation, the one or more HTTP clients establish a preconfigured number of connections with the one or more servers. Further, in an exemplary implementation, in an event the PMT unit [314] identifies that the number of connections is less than the preconfigured number of connections, the creating unit [304] may create a new connection with the one or more servers. In this implementation, the transmitting unit [316] may be further configured to transmit the added one or more queries to the one or more servers over the new connection. Also, in this implementation, in an event the PMT unit [314] identifies that the number of connections exceeds the preconfigured number of connections, the queueing unit [308] is further configured to wait for the one or more connections with the one or more servers to become available. In this implementation, the transmitting unit [316] is further configured to transmit the added one or more queries to the one or more servers once the one or more connections are available. [0076] In an exemplary implementation, the one or more queries comprises HTTP requests corresponding to at least one of GET, POST, PUT, DELETE, or other standard HTTP methods intended for communication with the one or more servers. [0077] The method [400] allows multiple connection requests to be sent asynchronously to increase the overall throughput of the application. Further, the method [400] allows the use of multiple connections to be optimized in a way such that these connections are created and teared down depending on the traffic currently being generated for proper resource utilization.

Upon receiving the RST packet, the client releases the connection state from its memory and frees the unusable resource and works upon creation of a new connection (if required) with the peer. [0078] The present disclosure also encompasses a user equipment (UE) for managing connections at Hypertext Transfer Protocol (HTTP) Client comprising a system. The system further comprises a connection establishing unit configured to establish one or more connections with one or more servers. Further, the system comprises a creating unit configured to create a queue for each of the one or more connections with the one or more servers, wherein the queue acts as a buffer for one or more queries awaiting transmission to the one or more servers. Further, the system comprises a receiving unit configured to receive the one or more queries from an application program interface (API) for the one or more servers. Further, the system comprises a queueing unit configured to add the one or more queries in the respective queue for the one or more servers. Further, the system comprises an identifying unit configured to identify an available connection with the one or more servers. [0079] The present disclosure also encompasses a non-transitory computer readable medium to store executable instructions for managing connections at Hypertext Transfer Protocol (HTTP) Client, the executable instructions when executed by one or more units of a system, cause: a connection establishing unit to establish one or more connections with one or more servers; a creating unit to create a queue for each of the one or more connections with the one or more servers, wherein the queue acts as a buffer for one or more queries awaiting transmission to the one or more servers; a receiving unit to receive the one or more queries from an application program interface (API) for the one or more servers; a queueing unit to add the one or more queries in the respective queue for the one or more servers; an identifying unit to identify an available connection with the one or more servers. [0080] As is evident from the above, the present disclosure provides a technically advanced solution for enhancing Hypertext Transfer Protocol (HTTP) client to efficiently use multiple connections to increase overall throughput of overall communication network. Various advantages of the present disclosure includes: x Asynchronous creation of multiple connection requests to increase the overall throughput of the system; x Optimization of the system to allow the use of multiple connections x Efficient and proper usage of the resources. x Efficient and reliable handling of the traffic handling during both the peak hours and lean hours. x Time-saving and efficient solution to solve the problem of stale state due to the idle connections. x The system allows the client to failover or failback between active and standby instances of the server and allows preventing any data loss without service disruption, in case any one of the instances is unreachable. It constantly checks for the reachability status of the server instance and restores the connections once it becomes reachable again. x The system supports secure message exchange with the server using Secure Socket Layer (SSL) or Transport Layer Security (TLS). This helps in maintaining integrity of data. x The custom HTTP Client can: adjust the number of connections as per requirement of the application; detect stale (idle) connections which have been closed by the server but their closure event was undetected at the client, and upon detection, it can retry the failed requests over new connections; and support secure communication.
