摘要： A network is monitored for reports indicative of a connection state among ports of a communications network. Certain ports are designated as being in a transition, and a transition table is created for each transition. The transition table includes locations that directly relate the connectivity of a first port with respect to a second port, as well as locations that relate the connectivity of other ports. The contents of the transition table are evaluated to determine the likely configuration of the communications network. State machines may be used to resolve conflicting data within the transition table, by providing a likely connection output based upon different entries within the transition table. A voting scheme is used to evaluate the outputs of the state machines and update the transition table when appropriate, and the updated transition table may also be evaluated.

摘要： Traffic on communications network is evaluated based on intra-subnet and inter-subnet traffic volumes. Values indicative of such volumes and of the overall network balance are displayed, along with alternative node topologies which may be evaluated and displayed. The overall network performance is based on equalizing intra-subnet traffic volume and minimizing inter-subnet traffic volume.

摘要： An object-oriented architecture for network layer routing is provided which distributes function and system behavior into autonomous router objects. By distributing these functionalities into each object, the services and data normally external to the object are imbedded or accessible within the object itself. In another sense, some objects are distributed across the network; e.g., a separate forwarding engine is provided at each network interface. In a preferred embodiment, each object has: (1) common, protocol-independent functions that are shared by all objects of that class; (2) their own configuration information; (3) accessibility through a router resource object for instantiation and control; (4) automatic persistence in NVRAM; (5) remote management capabilities; and (6) text names for navigation of a resource tree as a file system. These capabilities are in every object regardless of the specific protocol or application. This ensures a common architecture among many different systems/router components, a common method of control internally, a consistent order of instantiation and a common functional behavior.

摘要： Apparatus and method for establishing "virtual connections" through a switched data communications network which provides higher speed, lower cost, integrated services, and manageability. Once the virtual connection is established, the switches can move connectionless data packets along the established path in a straight-forward manner without transformation of the data packets. The complexities associated with routing data are pushed out of the data transfer path and are instead handled at connection establishment time. This allows the switches to be simpler and therefore faster. Also, the switching decision is substantially protocol independent and transparent to the end systems. It also yields important benefits in terms of manageability because capabilities which were too costly to perform on a packet-by-packet basis can readily be performed at connection establishment time. Thus, a new level of manageability can be achieved which was not practical with datagram oriented technology. Improved allocation of bandwidth and a new best path searching method are also provided.
摘要翻译：通过提供更高速度，更低成本，综合服务和可管理性的交换数据通信网络建立“虚拟连接”的装置和方法。一旦建立了虚拟连接，交换机可以沿着建立的路径以直接方式移动无连接的数据分组而不转换数据分组。与路由数据相关联的复杂性被推出数据传输路径，而是在连接建立时间处理。这允许开关更简单，因此更快。此外，切换决定基本上是协议独立的并且对于终端系统是透明的。它在可管理性方面也产生了重要的好处，因为在连接建立时可以容易地在逐个分组的基础上执行的代价太高的能力。因此，可以实现新的可管理性水平，这对于基于数据报的技术是不实际的。还提供了改进的带宽分配和新的最佳路径搜索方法。

摘要： A system and method for controlling access to a shared object among a plurality of interconnected processes. An associated lock token is generated for each shared object and a process must possess the lock token in order to access or to modify the associated object. When two or more processes are contending for the token at the same time, each process will wait for a random time period before again seeking control of the token.

摘要： A system and a method for managing forwarding table lookups and updates involve maintaining a first forwarding table in a first memory and a second forwarding table in a second memory, and then utilizing the first forwarding table to forward packets while the second forwarding table is updated with current route entries. The second forwarding table is updated in the background and therefore conventional CPU speeds do not cause performance problems. Once the second forwarding table is completely updated, a forwarding table pointer is switched and the second forwarding table is utilized to forward packets while the first forwarding table is updated. Because the second forwarding table has been completely updated in the background, switching the forwarding table pointer causes newly arriving packets to be forwarded according to a forwarding table that is free of inconsistencies.
摘要翻译：用于管理转发表查找和更新的系统和方法涉及将第一存储器中的第一转发表和第二存储器中的第二转发表保持在第二存储器中，然后利用第一转发表转发分组，同时更新第二转发表当前路由条目。第二个转发表在后台更新，因此常规CPU速度不会导致性能问题。一旦第二转发表被完全更新，则转换表指针被切换，并且第二转发表用于在更新第一转发表时转发分组。由于第二转发表已经在后台完全更新，所以切换转发表指针会根据没有不一致的转发表导致新到达的数据包转发。

摘要： A system provides representations of connections or other relationships among entities that make up a communications network. The representations may each have a color or shading to represent different conditions of the relationship. The representations may be graphical and may also include textual information as well as graphical hot-spots selectable by a user to provide even more detailed information regarding the relationship. The condition of each relationship may be determined based upon a combination of the conditions of the interface elements which are coupled together to form the communications relationship.

摘要： A switch for use in a communications system having multiple local area networks interconnected by multiple switches so as to be configurable into different types of virtual local area networks inclules first and second communication ports. The first communication port is connected directly to a local area network and the second communication port interconnects with other system switches. A switch control detects a communication from the local area network and identifies a virtual local area network over which the communication is to be transmitted based upon rules of precedence for different types of virtual local area networks. The communication is appended with a VLAN tag representing the identified virtual local area network so as to form a VLAN communication that is directed to the second communication port for transmission over the identified virtual local area network.

摘要： A translation is performed by using a programmable hashing technique on an input number to generate a hashed number (408). A subset (410) of the hashed number bits are used to index a first hash table (420). In first hash table locations (426) where a hash collision does not occur, the first hash table entry (426) contains an index (for IDX) into an output (438) table which contains the desired translated output number (436). In first hash table locations where a hash collision occurs (424), the first hash table entry (494) contains a pointer (NTI) to a first resolution table area in a second hash table. The first resolution table area contains entries which are indexed by additional bits selected from the hashed number in accordance with a mask field in the first hash table location. If collisions occur in the resolution table a new resolution table is created and the process is repeated. The resolution process thus proceeds in stages until all input numbers have been translated.
摘要翻译：通过在输入号码上使用可编程散列技术来产生翻译来产生散列数（408）。散列数位的子集（410）用于索引第一散列表（420）。在不发生哈希冲突的第一散列表位置（426）中，第一散列表条目（426）包含到包含所需转换输出数（436）的输出（438）表中的索引（用于IDX）。在发生哈希冲突的第一散列表位置（424）中，第一散列表条目（494）包含指向第二散列表中的第一分辨率表区域的指针（NTI）。第一分辨率表区域包含根据第一散列表位置中的掩码字段从由散列数选择的附加位索引的条目。如果在分辨率表中发生冲突，则创建一个新的分辨率表，并重复该过程。因此，分辨率过程分阶段进行，直到所有输入数字已经被翻译。
