摘要： A method, system and computer program product for managing bursts of traffic. A counter, referred to herein as a “frequency counter,” is incremented during those time intervals an overload condition is detected and is decremented during those time intervals an overload condition is not detected. An overload condition may refer to when the number of out-of-dialog messages exceeds a threshold value corresponding to the maximum number of out-of-dialog messages that should be accepted and forwarded to an associated session server. If the count of the frequency counter exceeds some pre-configured value, then traffic that exceeds the threshold for the overload condition is stopped from being sent to the associated session server. Otherwise, traffic that exceeds the threshold for the overload condition is permitted to be sent to the associated session server. By managing bursts of traffic in such a manner, the effective utilization of session servers is improved.

摘要： A method, system and computer program product for limiting extreme loads and reducing fluctuations in load at session servers. An admission rate controller of a SIP router calculates the “deflator ratio” equal to the average number of in-dialog messages received over a first fixed interval of time divided by the average number of out-of-dialog messages received over a second fixed interval of time. Further, the admission rate controller calculates the “dampening ratio” equal to the maximum number of messages allowed over a period of time divided by the number of messages admitted over a previous time interval. When an overload condition has been detected, the admission rate controller calculates the maximum number of out-of-dialog messages to be sent to its associated SIP server based on the deflator and dampening ratios. In this manner, a smoother transition from the overload condition to the non-overload condition may occur.

摘要： The number of CPU cycles required to reclaim object memory space in a memory management process is reduced by using a two phase approach. A data structure exists for each object that is to be loaded into object memory space. One part of the data structure is the object definition. The other part is a MM (Memory Management) immunity annotation or value that controls the frequency with which the object must actually be examined to determine if it is suitable for reclamation. On each iteration of the memory management process, the object's MM immunity value is tested to determine whether it is greater than a predetermined threshold. If greater than the threshold, the value is decremented, but the object is not actually examined for its suitability for removal. If the value equals the threshold, the object itself is examined. If it is found to be suitable, it is removed to reclaim the object memory space it previously occupied, If it is actually examined but is found not to be suitable for removal, the MM immunity value is reset to its original value or is otherwise adjusted to prevent examination of the object for a certain number of future iterations of the memory management process.

摘要翻译： 通过使用两相方法可以减少在内存管理过程中回收对象内存空间所需的CPU周期数。 对于要加载到对象内存空间的每个对象，都存在数据结构。 数据结构的一部分是对象定义。 另一部分是MM（内存管理）豁免注释或值，用于控制物体必须实际检查的频率，以确定是否适合回收。 在存储器管理过程的每次迭代中，测试对象的MM抗扰度值以确定其是否大于预定阈值。 如果大于阈值，则该值递减，但是实际上并没有检查该对象是否适用于删除。 如果该值等于阈值，则会检查对象本身。 如果发现是合适的，则将其删除以回收其以前占用的对象存储空间，如果实际检查但被发现不适合删除，则MM抗扰度值将重置为其原始值或进行其他调整 以防止对对象进行一定数量的未来内存管理过程的迭代。

摘要： A technique for use in a client, wherein the client supports a state-based signaling protocol (e.g., Session Initiation Protocol or SIP), includes initiating a given session state between the client and a server that also supports the state-based signaling protocol, and refreshing the given session state in a randomized manner. Further, a technique for use in a server, wherein the server supports a state-based signaling protocol (again, e.g., SIP), includes randomly assigning an expiration time duration for a given session state between the server and a client that also supports the state-based signaling protocol, and reporting the randomly assigned expiration time for the given session state to the client. By randomizing various behaviors of the client, the server, or both, bursty traffic in the communication network is reduced or eliminated.
