    Abstract:  広域網に余分な負荷をかけることなく、エッジスイッチのアクセスポートのつなぎ替えに伴う学習内容の消去または書き換えの自動化を行い、かつ、保守者の誤接続による網への悪影響の防止を行うため、ユーザ網をエッジスイッチのアクセスポートに接続する通信モジュールに備えられた記憶手段に、接続先のアクセスポートの識別番号を記憶しておく。エッジスイッチは、アクセスポートへの通信モジュールの接続を検出し、接続された通信モジュールの記憶手段に記憶された識別番号を読み出して該通信モジュールが接続されたアクセスポートの識別番号と比較し、ユーザ網の接続替えの判定を行い、通信モジュールの記憶手段に記憶されていた識別番号と通信モジュールが接続替えで接続されたアクセスポートの識別番号を広域網内のスイッチに通知する。

    Abstract: A failover transition system for a VLAN is disclosed in which a master switch and a standby switch are designated, as in the case of ESRP. When a network failure is detected, the master switch "bounces" or restarts auto-negociation of a set of physical ports on the VLAN. In this way, ports are forced to re-ARP to update their forwarding database information immediately rather than wait until expiration of an ARP max age timer, resulting in a decreased failover transition time.

    Abstract: An iterative method of correcting errors in a data block (164). Bad bytes are first identified using information derived from an 8B/10 encoding/decoding of the data block (164). Within each identified bad byte, suspect bits are subsequently identified using information derived from parity encoding of a row of the data block (164) in which the bad byte is located. Each suspect bit is then classified as either a confirmed error bit or as an unconfirmed error bit using information derived from parity encoding of a column of the data block (164) in which the suspect bit is located. Confirmed error bits are then corrected, the parity bits corresponding to the confirmed error bit reset, and the bad byte cleared. The process is then repeated if one or more bad byte remain in the data block (164).

    Abstract translation: 一种校正数据块中的错误的迭代方法(164)。 首先使用从数据块(164)的8B / 10编码/解码得到的信息来识别坏字节。 在每个识别的不良字节中,随后使用从错误字节所在的数据块(164)的行的奇偶校验编码得到的信息来识别可疑位。 然后,使用从可疑位所在的数据块(164)的列的奇偶校验编码得到的信息将每个可疑位分类为确认的错误位或作为未确认的错误位。 然后校正确认的错误位,与确认的错误位复位相对应的奇偶校验位和坏字节清零。 如果一个或多个坏字节保留在数据块(164)中,则重复该过程。

    Abstract: A method of scheduling a processor to handle a plurality of connections with respective processing cycles. The method includes estimating, for at least one of the connections, whether the connection will receive a processing session during its current respective processing cycle if each of the connections which did not yet receive a processing session during its current processing cycle receives, during its current processing cycle, an unlimited processing session and scheduling one or more of the connections that did not yet receive a processing session in their respective processing cycle, to perform a limited processing session, responsive to results of the estimation.

    Abstract: A packet-switch system utilizes a linecard-to-switch (LCS) protocol to integrate linecards with a switch core. Since the linecards include a majority of the buffering of the system and are located physically away from switch core, the size of the switch core can be reduced in size. The LCS protocol is a label-swapping, credit-based, flow-control, which enables the system to operate without requiring such information as the number of port modules available within a switch core or what Qualities of Service (QoS) or multicast flows are available. In addition, the LCS protocol enables the linecards to contain and manage the majority of the buffers in the system, and also to control the data drop policy within the system.

    Abstract: A router fault tolerant network interface system (300) includes a switch circuit (302) configured to detect when a router fails in a multi-router local network. When a failed router (202) is detected, the switch circuit (302) waits for a time-out period to expire to allow convergence. The switch circuit (302) then intervenes when traffic from a server (106) to the failed router (202) is detected. The switch circuit (302) translates the MAC address of the failed router (202) to the MAC address of a functional router (104). Traffic from a server (106) originally directed to the failed router (202) is then redirected to a functional router (104). In a further refinement, the switch circuit (302) provides the MAC address of a functional router (104) in response to an ARP request from a server (106) to the failed router (202).
