摘要： The present disclosure generally discloses packet processing offload support capabilities for supporting packet processing offload. The packet processing offload support capabilities may be configured to support general and flexible packet processing offload at an end host by leveraging a processing device (e.g., a smart network interface card (sNIC) or other suitable processing device) added to the end host to support offloading of various packet processing functions from the hypervisor of the end host to the processing device added to the end host. The packet processing offload support capabilities may be configured to support packet processing offload by including, within the end host, a virtualization switch and a packet processing offload agent which may be configured to cooperate to transparently offload at least a portion of the packet processing functions of the end host from the hypervisor of the end host to an sNIC of the end host while keeping the existing management plane and control plane interfaces of the datacenter unmodified.

摘要： A switch schedules guaranteed-bandwidth, low-jitter-traffic characterized by a guaranteed rate table (GRT) method. A rate matrix generated from collected provisioning information is decomposed into schedule tables by a low jitter (LJ) decomposition method. The LJ decomposition method imposes a set of constraints for the schedule tables: schedule tables are partial permutation matrices, weighted sum of the partial permutation matrices is greater than or equal to the weighted sum of the rate matrix, and each entry in the rate matrix belongs to one element of the LJ decomposition schedule matrices. An integer LJ decomposition programming problem is employed to generate the schedule tables that are scheduled for each time slot of the period of the switch. Schedule tables are selected in turn based upon selecting eligible tables having the earliest finishing time. If necessary, the rate matrix is updated prior to decomposition for a subsequent period.

摘要： A network of nodes interconnected by links, such as a wavelength division multiplexing (WDM) ring network, is modeled by a delayed graph in which propagation delay between nodes is accounted for. Given the delayed graph, a traffic matrix for an admissible traffic pattern is scheduled over a frame period. Scheduling of the traffic matrix formulates a set of scheduling constraints based on the delays and decomposes the traffic matrix into a set of transmission matrices. Each of the set of transmission matrices is scheduled over the frame period.

摘要： A packet filter for a router performs generalized packet filtering allowing range matches in two dimensions, where ranges in one dimension at least one dimension is defined as a power of two. To associate a filter rule with a received packet EP, the packet filter employs a 2-dimensional interval search and memory look-up with the filter-rule table. Values of sm of filter-rule rm=(sm,dm) in one dimension are desirably ranges that are a power of two, such as prefix ranges, which are represented by a binary value having a “length” defined as the number of bits to of the prefix. The dm may be single points, ranges defined as prefix ranges, and/or ranges defined as continuous ranges. The packet filter employs preprocessing of the filter-rules based on prefix length as a power of 2 in one dimension and decomposition of overlapping segments into non-overlapping intervals in the other dimension to form the filter-rule table. A preprocessing algorithm searches in one dimension through filter rules and arranges the corresponding filter-rule rectangle segments according to prefix length. Then, in the other dimension, the overlapping filter rectangle segments are decomposed into non-overlapping intervals, and the highest priority filter-rule overlapping each non-overlapping interval is associated with that interval. A filter-rule table is then constructed with entries ordered according to prefix length and non-overlapping interval, each entry associated with a particular filter-rule. A packet classification algorithm then matches the field or other parameter information in the packet to the filter-rule table entries to identify the filter-rule rectangle associated with the filter-rule to be applied to the packet.
摘要翻译：用于路由器的分组过滤器执行广义分组过滤，允许在二维中进行范围匹配，其中一维中的至少一维的范围被定义为二的幂。为了将过滤规则与接收到的分组EP相关联，分组过滤器采用二维间隔搜索和存储器查找与过滤规则表。一维中滤波器规则rm =（sm，dm）的sm的值优选为2的幂，例如前缀范围的范围，前缀范围由具有定义为位数的“长度”的二进制值表示到前缀。 dm可以是单点，定义为前缀范围的范围，和/或定义为连续范围的范围。分组过滤器使用基于前缀长度的过滤规则的预处理作为一维中的2的幂，并且将重叠段的分解在另一维度中的非重叠间隔中以形成过滤规则表。预处理算法通过过滤规则在一维中进行搜索，并根据前缀长度排列相应的过滤规则矩形段。然后，在另一个维度上，重叠的过滤器矩形段被分解成非重叠的间隔，并且与每个非重叠间隔重叠的最高优先级过滤器规则与该间隔相关联。然后，根据前缀长度和不重叠间隔排序的条目构建过滤规则表，每个条目与特定过滤规则相关联。然后，分组分类算法将分组中的字段或其他参数信息与过滤器规则表条目匹配，以标识与要应用于分组的过滤规则相关联的过滤规则矩形。
