摘要： A method and apparatus of a device that determines a cause and effect of congestion in this device is described. In an exemplary embodiment, the device measures a queue group occupancy of a queue group for a port in the device, where the queue group stores a plurality of packets to be communicated through that port. In addition, the device determines if the measurement indicates a potential congestion of the queue group, where the congestion prevents a packet from being communicated within a time period. If potential congestion exists on that queue group, the device further gathers information regarding packets to be transmitted through that port. For example, the device can gather statistics packets that are stored in the queue group and/or new enqueue packets.

摘要： An adjunct network device includes several ports, an uplink interface, and an adjunct forwarding engine coupled to the ports and the uplink interface. A first port is configured to receive a packet, which includes a destination address. The adjunct forwarding engine is configured to send the packet to the uplink interface if the destination address is not associated with any of the ports. The packet is sent to one of the ports if the destination address is associated with the one of the ports.

摘要： Systems and methods for automatically controlling efficient operation of a plurality of network appliances operatively linked and networked to balance network traffic load across a plurality of network appliances that are selectively enabled. The system facilitating performance of the method includes at least a plurality of network appliances operatively connected to a switch and controlled by a network access control module. During system operation, at any given moment in time, the plurality network appliances operate in one of two modes, fully operational or stand-by. The network appliances of the plurality that are fully operational and thereby consuming full operational power depends upon the network traffic load at any given moment in time. The network appliances functioning in a stand-by mode consume low power levels which are sufficient to allow a network appliance in stand-by mode to receive a command signal directing it to switch from stand-by to full operational mode.

摘要： Layer 7 switching may be accomplished using one or more caches placed throughout a computer network. Changes to a file on a server may be detected and propagated throughout the network. At the switch or router level, once notification of changes to a file is received, the content may be retrieved from the server and placed in a connected cache. A routing table entry may be created for the content and also placed in the cache. The routing table entry may contain an original location field identifying the original location of the content, a distance field indicating a distance from the cache to the server, and a field indicating a version number of the content. Additional fields may also be contained within the routing table entry. When a user requests a specific file, rather than forward the request directly to the server containing the original file, the request may be handled by the router closest to the user which has a connected cache containing the content. This allows a user's request to be handled much more quickly and efficiently than prior art solutions.

摘要翻译： 可以使用放置在整个计算机网络中的一个或多个高速缓存来实现层7切换。 可能在整个网络中检测并传播对服务器上文件的更改。 在交换机或路由器级别，一旦接收到对文件的更改的通知，可以从服务器检索内容并将其放置在连接的高速缓存中。 可以为内容创建路由表条目，并将其放置在高速缓存中。 路由表条目可以包含标识内容的原始位置的原始位置字段，指示从缓存到服务器的距离的距离字段以及指示内容的版本号的字段。 附加字段也可以包含在路由表条目中。 当用户请求特定文件而不是将请求直接转发到包含原始文件的服务器时，该请求可以由最接近具有连接的缓存包含该内容的用户的路由器处理。 这允许用户的请求比现有技术的解决方案更快速和有效地处理。

摘要： In order to direct content requests to an appropriate content serving site in a computer network, a phased learning approach is utilized to ensure that, as best as possible, the request is made to content serving site with the shortest delay. In a setup phase, an indirect path return geographic sever load balancer times sends transit time requests to all of the individual content serving sites so that the transit requests all arrive at the content serving sites at the same time. Therefore, when the requesting fixed location receives communications from the content serving sites, it can easily tell which content serving site has the least delay by an established race condition. The winner of the race may then be relayed to the indirect path return geographic server load balancer for later usage. In an execution mode, only the m fastest content serving sites and n other sites (used to test random and new sites) are sent a transit time request when a DNS request arrives from the requesting fixed location. The particular m fastest content serving sites and n other sites may be dynamically updated so as to ensure the most reliable directing of requests. This solution provides a very efficient and effective means by which to determining closest content serving sites while keeping load balancer-created traffic at a minimum.

摘要： Enhanced tunnel communication mode creation, management and tuning in a network that includes wireless access points (APs) and user authentication. Tunnels can be dynamically managed to adapt to the changing topology of a network with APs. User devices such as mobile phones, laptop computers, personal digital assistants, or other devices can be added or dropped from an assigned AP. APs, routers, switches or other devices can also be added, removed, or modified in their network characteristics. Special control is also provided for IP multicast, Dynamic Host Configuration Protocol (DHCP), Address Resolution Protocol (ARP) and other network features.

摘要： Methods and systems for using counters to monitor port buffers are described. In one embodiment, the method includes receiving data packets into a system port buffer having different queues. Also, counters are associated with the queues. Further, the method includes scanning the counters, in which the counters count the number of dropped data packets associated with an individual queue of the different queues. Moreover, the method includes determining if the number of dropped data packets for an individual queue is greater than a predetermined number. If the number of dropped data packets is greater than the predetermined number, then a message is generated.

摘要： More effective load balancing by a Server Load Balancer may be achieved by implementing extended Server Load Balancing information in a server. The extended Server Load Balancing information includes a special listing of “hot” objects, or objects that have been designated for special handling by the Server Load Balancer. In order to determine which objects on a server are “hot” at any particular point in time, the available throughput for the server is determined. This is then multiplied by a “hotness” percentage, resulting in an Object Threshold Value (OTV). Each of N objects is then assigned an Object Request Value (ORV), the N objects determined by taking the N objects utilizing the most bandwidth. The ORVs are then compared with the OTV, and any of the objects whose ORV exceeds the OTV are labeled as “hot”. Finally, information on the “hot” objects is communicated to the Server Load Balancer (SLB) for special handling.
