Abstract
Abstract An acceptor for admitting incoming requests to a server application includes a session manager that determines the class of an incoming request. The class includes a first class and a second class. A queuing module is provided to store the request if the incoming request is of the second class. A priority control module is provided to ensure that a predetermined number of requests are sent to the server application for service in each cycle. The priority control module allows (1) the predetermined number of the first class requests to be sent to the server application if the first class requests received in a cycle are at least equal to the predetermined number, and (2) a mixture of the first class requests and the second class requests to be sent to the server application if the first class requests received in a cycle are less than the predetermined number. A method of handling incoming requests to the server application is also described.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
180 words
An acceptor for admitting incoming requests to an external server application, comprising: a session manager that determines whether an incoming request is a premium existing session request; a priority control module for ensuring identified existing session premium requests are made available to the server application in each server intake cycle ahead of other requests, wherein the priority control module (1) processes a maximum of K incoming requests during each cycle, (2) makes available a predetermined number M<K of premium requests to the server application during said cycle if at least M said incoming premium existing session requests have been processed by the priority control module during said cycle, and (3) makes available to the server application all the incoming premium existing session requests processed during said cycle if the number n of such requests is less than M; and a queuing module that holds the other requests that have been processed by the priority control module during the current cycle until all of the premium existing session requests processed during that cycle have been made available to the server application.
Claim 2
Dependent Claim
180 words
An acceptor for admitting incoming requests to an external server application, comprising: a session manager that determines whether an incoming request is a premium existing session request; a priority control module for ensuring identified existing session premium requests are made available to the server application in each server intake cycle ahead of other requests, wherein the priority control module (1) processes a maximum of K incoming requests during each cycle, (2) makes available a predetermined number M<K of premium requests to the server application during said cycle if at least M said incoming premium existing session requests have been processed by the priority control module during said cycle, and (3) makes available to the server application all the incoming premium existing session requests processed during said cycle if the number n of such requests is less than M; and a queuing module that holds the other requests that have been processed by the priority control module during the current cycle until all of the premium existing session requests processed during that cycle have been made available to the server application.
Claim 3
Dependent Claim
15 words
The acceptor of claim 1 , wherein the server application is a TCP/IP-based server application.
Claim 4
Dependent Claim
15 words
The acceptor of claim 1 , wherein the server application is a web server application.
Claim 5
Dependent Claim
25 words
The acceptor of claim 1 , wherein the priority control module is coupled to the session manager, the queuing module, and the external server application.
Claim 6
Dependent Claim
43 words
The acceptor of claim 1 , wherein when the priority control module makes available only n<M existing session premium requests to the server application, the priority control module causes the queuing module to forward M−n of the other requests in a first-in-first-out fashion.
Claim 7
Dependent Claim
36 words
The acceptor of claim 5 , further comprising a classification module coupled to the queuing module to select which of the other requests are to be forwarded to the server application as premium new session requests.
Claim 8
Dependent Claim
46 words
The acceptor of claim 6 , wherein the session manager also identifies other existing session requests and new session requests, and when the classification module forwards some of those other requests to the server application, the classification module gives priority to the other existing session requests.
Claim 9
Dependent Claim
40 words
The acceptor of claim 1 , wherein M and K are predetermined values that are at least partially dependent on the system configuration, and at least K is automatically set and dynamically changed based on changes in the input load.
Claim 10
Dependent Claim
16 words
The acceptor of claim 1 , wherein M and K are selected to maximize system capacity.
Claim 11
Dependent Claim
23 words
The acceptor of claim 1 , wherein M and K are selected to minimize system response time for the premium existing session requests.
Claim 12
Independent Claim
108 words
A method of admitting incoming requests to a server application during a server intake cycle, comprising determining for each of up to K incoming requests, whether the request is a premium existing session request, storing in a queuing module those incoming requests that are determined to not be premium existing session requests; if at least M<K premium existing session requests are included in the K incoming requests, sending all M premium existing session; if only n<M<K premium existing session requests are included in the K incoming requests, sending to the server application all n premium existing session requests and M−n other requests previously stored in the queuing module.
Claim 13
Independent Claim
108 words
A method of admitting incoming requests to a server application during a server intake cycle, comprising determining for each of up to K incoming requests, whether the request is a premium existing session request, storing in a queuing module those incoming requests that are determined to not be premium existing session requests; if at least M<K premium existing session requests are included in the K incoming requests, sending all M premium existing session; if only n<M<K premium existing session requests are included in the K incoming requests, sending to the server application all n premium existing session requests and M−n other requests previously stored in the queuing module.
Claim 14
Dependent Claim
27 words
The method of claim 11 , wherein the total number of requests sent to the server application during a particular server intake cycle is equal to M.
Claim 15
Dependent Claim
60 words
The method of claim 12 , further comprising the steps of classifying the other requests stored in the queuing module as either existing session other requests or new session other requests; and selecting first the existing session other requests to be sent to the server application when some of the other requests need to be sent to the server application.
Claim 16
Dependent Claim
40 words
The method of claim 11 , wherein M and K are predetermined values that are at least partially dependent on the system configuration, and at least K is automatically set and dynamically changed based on changes in the input load.
Claim 17
Dependent Claim
16 words
The method of claim 11 , wherein M and K are selected to maximize system capacity.
Claim 18
Dependent Claim
23 words
The method of claim 11 , wherein M and K are selected to minimize system response time for the premium existing session requests.
