摘要： Systems, apparatus and methods for the implementation of high-speed network analyzers are provided. A set of high-level specifications is used to define the behavior of the network analyzer emitted by a compiler. An optimized inline workflow to process regular expressions is presented without sacrificing the semantic capabilities of the processing engine. An optimized packet dispatcher implements a subset of the functions implemented by the network analyzer, providing a fast and slow path workflow used to accelerate specific processing units. Such dispatcher facility can also be used as a cache of policies, wherein if a policy is found, then packet manipulations associated with the policy can be quickly performed. An optimized method of generating DFA specifications for network signatures is also presented. The method accepts several optimization criteria, such as min-max allocations or optimal allocations based on the probability of occurrence of each signature input bit.

摘要： In a multi-processor (e.g., multi-core) computer system, several processors can simultaneously access data without corruption thereof by: designating to each processor a portion of a hash table containing the data; by allowing each processor to access only those data elements belonging to the portion of the hash table designated to that processor; and by sending, via a network, other data elements to the processors that are designated the portions of the hash table to which the other data elements belong. The network avoids memory contention at each processor without requiring a memory-based lock. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

摘要： Solution methods for ensuring control and data packets to traverse network address translators (NATs) and firewalls, when a mobile terminal acquires a new (Internet Protocol) address and may move behind a new NAT/firewall are provided. These solutions form an integral part of seamless mobility and multipath packet delivery in IP networks. The solution approach decomposes the problem into downstream control-plane, downstream data-plane, and upstream data-plane sub-problems. The solution is scalable as it does not require a new routing infrastructure, except in the case of traversing a symmetric NAT, a middle box is used as a relay

摘要： There is provided a system and method for providing a simple yet flexible overlay network on top of any IP networks to enable diverse network applications whereby much of the rigidities of IP protocol suite are eliminated without any modifications to the applications. In particular, the system includes: a plurality of c-nodes; one or more source terminal nodes connected to an IP network; and one or more destination terminal nodes connected to the IP network. Here, the source terminal nodes send IP packets over the plurality of c-nodes to the destination terminal nodes to accomplish arbitrary communications between arbitrary groups of the source terminal nodes to arbitrary groups of the destination terminal nodes. More specifically, a method employing the system utilizes the concept of connection ID and headers that can be inserted anywhere in the IP packet.

摘要： There is provided a method of delivering a plurality of source streams from a plurality of servers to a plurality of clients through a plurality of routers over a communication network using a pay-per-period pricing scheme. Said method includes: splitting the source stream into a plurality of sub-streams to the routers; estimating available capacities of the plurality of the routers; and delivering the sub-streams to the routers at transmission rates proportional to the available capacities of the routers. The available capacity is estimated based on input and output traffic correlations in the server. Further, the client, who is not an owner of the available capacity, may be allowed to use the available capacity at a lower priority than that of the owner. The delivery of the source stream may be carried out over a plurality of paths over the communication network, wherein time-space trajectories of the paths do not cross each other. The method of the present invention provides a large-scale optimal exploitation of available capacities such as network bandwidths and computing resources for content delivery, while ensuring high QoS of content delivery.
摘要翻译：提供了一种通过使用每个期付费方案在通信网络上通过多个路由器从多个服务器向多个客户端递送多个源流的方法。所述方法包括：将源流分解成多个子流到路由器; 估计所述多个路由器的可用容量; 并以与路由器的可用容量成比例的传输速率将子流传送到路由器。可用容量根据服务器中的输入和输出流量相关性进行估计。此外，不是可用容量的所有者的客户可能被允许以比所有者的优先级低的优先级使用可用容量。源流的传送可以在通信网络上的多个路径上执行，其中路径的时间 - 空间轨迹不相互交叉。本发明的方法提供了对可用容量的大规模优化利用，例如用于内容传送的网络带宽和计算资源，同时确保内容传送的高QoS。
