摘要： Systems and methods for committed access rate (CAR) system architecture in an IP/Ethernet network with optional dynamic packet memory reservation are disclosed. The method includes classifying each received packet into a quality of service (QoS) group using the packet header information, defining a traffic transmission rate profile such as by using a token bucket model to measure and check the traffic rate profile of the incoming packet against a corresponding service level agreement (SLA), marking the packet as in profile or out of profile, and performing packet buffer memory reservation to guarantee memory space for in profile CAR packets. Buffer memory reservation may be via static or dynamic memory reservation. Dynamic memory reservation eliminates the need for hard boundaries to restrict non-CAR packets. A push-out (e.g., head-drop) mechanism may be employed to push out non-CAR packets when the network traffic is congested.

摘要： A method and apparatus to perform a multi-field matching search. A search unit groups single fields of a multiple-field source into a search target having multiple-field keys (MFKs) whose single fields correspond to the single fields in multiple-field vectors (MFVs) of entries in a data structure. The search unit generates a set of queries based, at least in part, on the MFKs, where each query has a different MFK as a lead MFK. The search unit determines, based, at least in part, on a query, whether the non-wildcard values in the MFVs of an entry match the non-wildcard values in corresponding MFKs of the search target. If no entry has non-wildcard values in the MFVs that match the corresponding non-wildcard values in the MFKs, the search unit searches for, based, at least in part, on the set of queries, the entry having non-wildcard values in a MFV that match the non-wildcard values in a corresponding lead MFK, plus remaining MFVs that match corresponding remaining MFKs based on matching the non-wildcard values and wildcard values.
摘要翻译：一种执行多场匹配搜索的方法和装置。搜索单元将多场源的单个字段组合成具有多字段密钥（MFK）的搜索目标，其单个字段对应于数据结构中条目的多个字段向量（MFV）中的单个字段。搜索单元至少部分地基于MFK生成一组查询，其中每个查询具有不同的MFK作为引导MFK。搜索单元至少部分地基于查询来确定条目的MFV中的非通配符值是否匹配搜索目标的相应MFK中的非通配符值。如果没有条目具有与MFK中相应的非通配符值匹配的MFV中的非通配符值，则搜索单元至少部分地基于查询集来搜索具有非通配符值的条目匹配相应引线MFK中的非通配符值的MFV，以及基于匹配非通配符值和通配符值的相应剩余MFK的剩余MFV。
