摘要： For electrical backplanes and the like, a power plane adaptation to improve the propagation of high-speed signals through clearances in an embedded power plane is disclosed. In exemplary embodiments, the power plane is segmented in a high-speed connector region, such that a portion of the metal layer that forms the power plane is retained in the high-speed connector region—but isolated from the power-delivery portion of the power plane. The isolated portion is connected to digital ground, and clearances are formed therein where high-speed signaling throughholes will pass through the region. In some embodiments, various attainable advantages include better manufacturability, better matching and control of high-speed signaling throughhole impedance, and improved noise isolation. Other embodiments are described and claimed.

摘要： A trusted relationship service includes a certificate authentication server and a secure file host. The certificate authentication server operates to receive requests from a supplier and a customer to register with the service, verifies the identities of the supplier and the customer and sends digital certificates to both the supplier and the customer. The supplier can send information to the trusted relationship service where it is posted in a secure file host. The supplier can solicit the customer to visit the trusted relationship service web site to view the supplier information stored there, whereupon the customer can use their digital certificate to access the trusted relationship service site and is granted permission by the site to view the supplier information.

摘要： A local network, such as a data center, includes a plurality of servers each of which are linked to a network switch. Some of the plurality of servers are network virtualization capable and some are not. The network virtualization capable servers include functionality that encapsulates a data frame, generated by one network virtualization servers that is to be sent to another network virtualization capable server, with a network virtualization identity. In the event that a network virtualization server generates a data frame for transmission to a server that is not capable of network virtualization, the network virtualization capable server does not encapsulate the data frame with the network virtualization identity.

摘要： A packet network device includes a control module, one or more line cards each one or which includes a plurality of ingress and egress ports, and each of the ingress and egress ports are connected to external network links. The line cards maintain forwarding tables and include functionality that employs information in the forwarding tables to determine how incoming packets of information should be forwarded. The control module includes functionality that operates to learn reachability information about other devices connected to the network that are and to use this reachability information to update forwarding tables maintained on the line cards. The control module also includes an enhance ARP functionality that operates in cooperation with standard ARP functionality and other network protocols included on the control module to diminish the amount of data lost in the event that a link connected to one of the egress ports fails.

摘要： A stacked chassis comprising multiple physical switch/router chassis operates without any special stacking hardware or stacking channels. Instead, a stacking LAG is installed between front-end switch ports on the stacked chassis. The chassis controllers negotiate a master, which controls operation of all chassis in the stack. A stacked-chassis-wide port numbering scheme is used to distribute information to all line cards in the system. Each line card processes the information to distill physical-chassis significant information for operation of that chassis in the stack.

摘要： In one embodiment of a network device, multiple packet sources contend for access to a packet processing pipeline. The packet processing pipeline tracks the usage of lookup resources by each of the multiple packet sources. When a packet source is detected to be using more than an acceptable allocation of the lookup resources, access to the packet processing pipeline for that source is limited or curtailed to bring that source back within an acceptable allocation of resources. This backpressure mechanism can be used to control sources that, although within a bandwidth limit, are submitting a packet type mix that is consuming unfair percentages of lookup resources in an oversubscribed system. Other embodiments are described and claimed.

摘要： A packet network device has multiple equal output paths for at least some traffic flows. The device adjusts load between the paths using a structure that has more entries than the number of equal output paths, with at least some of the output paths appearing as entries in the structure more than once. By adjusting the frequency and/or order of the entries, the device can effect changes in the portion of the traffic flows directed to each of the equal output paths. Other embodiments are described and claimed.

摘要： Traffic engineering using a label-switching protocol is enhanced for label-switched paths that traverse a logical link that is an aggregation of component links. In one embodiment, a label edge router is provided with information regarding the bandwidth capabilities and loading of the component links of a LAG. The label edge router is then allowed to set up paths that traverse a specific component link of a LAG, and reserve bandwidth on such a component link. Other traffic may continue to be distributed across the LAG membership.

摘要： An accelerated boot process for a multiprocessor system and system components for use with the process are disclosed. Each processor caches at least one compressed system image in local nonvolatile memory. The processors boot concurrently, each using a local image. After a master processor is booted, the other processors verify with the master that each has booted a correct image version. Various redundancy and fallback features are described, which guarantee that all cards can boot and operate even if the preferred local system image contains a defect.
