摘要： A ring node N belonging to a resilient MPLS ring (RMR) provisions and/or configures clockwise (CW) and anti-clockwise (AC) paths on the RMR by: (a) configuring two ring node segment identifiers (Ring-SIDs) on the ring node, wherein a first of the two Ring-SIDs (CW-Ring-SID) is to reach N in a clockwise direction on the ring and a second of the two Ring-SIDs (AC-Ring-SID) is to reach N in an anti-clockwise direction on the ring, and wherein the CW-Ring-SID and AC-Ring-SID are unique within a source packet routing in networking (SPRING) domain including the ring; (b) generating a message including the ring node's CW-Ring-SID and AC-Ring-SID; and (c) advertising the message, via an interior gateway protocol, for receipt by other ring nodes belonging to the ring such that (1) a clockwise multipoint-to-point path (CWP) is defined such that every other one of the ring nodes belonging to the ring can be an ingress for the CWP and such that only the node is an egress for the CWP, and (2) an anti-clockwise multipoint-to-point path (ACP) is defined such that every other one of the ring nodes belonging to the ring can be an ingress for the ACP and such that only the node is an egress for the ACP.

摘要： Echo or traceroute functionality is supported in a path spanning multiple autonomous systems (ASes) having segment routing (SR) enabled, the path including an ingress node and an egress node, by: (a) obtaining a return label stack to reach the ingress node from either (A) the egress node, or (B) a transit node in the path; (b) obtaining a label stack to reach, from the ingress node, either (A) the egress node, or (B) the transit node; (c) generating a request message including the return label stack; and (d) sending the request message towards either (A) the egress node, or (B) the transit node using the label stack. The example method may further include: (e) receiving, by either (A) the egress node, or (B) the transit node, the request message, wherein the request message includes information for performing a validity check; (f) performing a validity check using the information included in the request message to generate validity information; (g) generating a reply message including the validity information and information from the return label stack; and (h) sending the reply message towards the ingress node using information from the return label stack included in the request message.

摘要： A focus adjustment device, comprising: a processor having a main physical object position detection circuit for detecting position of a main object based on an image signal, a distance value detection circuit for detecting distance values in accordance with object distance of a plurality of AF regions based on the image signal, a candidate region setting section for setting regions exhibiting a distance value for a close-range side of greater than a specific value, with respect to a statistic for distance value of regions corresponding to position of the main physical object, to unnecessary candidate regions, and a control section for determining regions corresponding to unnecessary physical objects based on the unnecessary candidate regions, and controlling focus adjustment based on distance value corresponding to regions that have had regions corresponding to the unnecessary physical objects excluded from the main physical object regions.

摘要： The same prefix segment identifier (SID) may be configured and/or used for either (A) more than one prefix within an interior gateway protocol (IGP) domain, or (B) one prefix with more than one path computation algorithm within the IGP domain by: (a) receiving, by a node in the IGP domain, an IGP advertisement including both (1) a prefix SID and a segment routing global block (SRGB) slice identifier; (b) determining whether or not the SRGB slice identified by the SRGB slice identifier is provisioned on the node; and (c) responsive to a determination that the SRGB slice identified by the SRGB slice identifier is not provisioned on the node, not processing the prefix SID included in the received IGP advertisement, and otherwise responsive to a determination that the SRGB slice identified by the SRGB slice identifier is provisioned on the node, (1) processing the prefix SID and SRGB slice to generate a unique, per SRGB slice, MPLS label for the prefix, and (2) updating a label forwarding information base (LFIB) for the node using the unique, per SRGB slice, label for the prefix and the prefix.

摘要： An autonomous system border router (ASBR) provided in a domain in which routers share an anycast address, may perform a method comprising: (a) receiving, from an exterior Border Gateway Protocol (eBGP) peer, first reachability information for a first prefix, the first reachability information including a first next hop (NH) address; (b) communicating first link state information about the first prefix to another router in the domain, the first link state information associating the first prefix with the anycast address; (c) receiving, from an eBGP peer, second reachability information for a second prefix, the second reachability information including a second next hop (NH) address; and (d) communicating second link state information about the second prefix to the other router in the domain, the second link state information associating the second prefix with the anycast address. This effectively reduces the number of next hops related to a prefix learned by two or more ASBRs (e.g., one or more spine routers in a Clos of an aggregate spine) via eBGP, stored as forwarding information on a non-ASBR in an IGP domain (e.g., on a leaf node in a Clos of an aggregate spine).

摘要： The challenge of protecting caps from excess perspiration is solved by providing a hat liner comprising: (a) a first portion including a plurality of tabs separated by one or more gaps, the first portion dimensioned so that at least a part of it fits between, and is held by, the sweatband of a cap and one or more front panels of a hat; and (b) a second portion, directly or indirectly joined with the first portion along a length, and including at least one moisture absorbing layer. The second portion may further include at least one moisture wicking layer. The first portion may include at least three tabs defined and separated by at least two gaps. At least some of the two gaps may have a wider open end and a narrower closed end. Each of the plurality of tabs in the first portion may be provided with a plurality of lateral ridges. The second portion may be indirectly joined with the first portion via the hinge portion. The hinge portion is provided with a plurality of lateral slits.

摘要： An image sensor, comprising pixels that have paired first pixel sections and second pixel sections, and a pixel signal generation circuit that repeatedly outputs an pixel signal, wherein the pixel signal generation circuit in a first frame among image frames, adds pixel signals of the first pixel sections corresponding to a first column to generate a first pixel addition signal, adds pixel signals of the second pixel sections corresponding to a second column to generate a second pixel addition signal, and respectively outputs the first and second pixel addition signals, and in a second frame that is continuous to the first frame, adds outputs of the second pixel section corresponding to the first column to generate a third pixel addition signal, adds outputs of the first pixel section corresponding to the second column to generate a fourth pixel addition signal, and respectively outputs the third and fourth pixel addition signals.

摘要： An image pickup apparatus includes an image pickup device, a display device including, in a finder loupe visual field, an image display region and an image display outside region, and a display controller configured to control the display device. The display controller determines a difficulty degree of visibility of a boundary between the image display region and the image display outside region and controls the display device to draw a boundary display when the difficulty degree is equal to or larger than a predetermined value and not to draw the boundary display when the difficulty degree is smaller than the predetermined value.
