摘要： In one embodiment, a method includes receiving, by a first autonomous system border router (ASBR) of a first autonomous system (AS), a first plurality of provider-provisioned media access control (B-MAC) addresses via Interior Border Gateway Protocol (I-BGP). Each of first plurality of B-MAC addresses is associated with a provider edge (PE) device of the first AS. The first ASBR sends the first plurality of B-MAC addresses to a second ASBR of a second AS using Exterior Border Gateway Protocol (E-BGP). The first ASBR also receives via E-BGP a second plurality of B-MAC addresses each of which is associated with a PE device of the second AS. The first ASBR then distributes the second plurality of B-MAC addresses to each of the PE devices of the first AS using I-BGP.

摘要： A method of transferring application layer network information comprises the computer-implemented steps of electronically transferring, from a first electronic digital data processor to a second electronic digital data processor, one or more transport layer connections associated with one or more application layer sessions; creating and sending, to the second processor, one or more application layer messages that appear to initiate a new application session with a peer; creating and sending, to the second processor, one or more application update messages that transfer application data from the first processor to the second processor; repeating the creating and sending steps for all application layer sessions that are active at the first processor. One embodiment provides stateful switchover of BGP sessions when one BGP host in a redundant system restarts asynchronously with respect to another host, without problems associated with bulk transfer of BGP route information.

摘要： Disclosed are, inter alia, methods, apparatus, data structures, computer-readable media, and mechanisms, for scheduling items in a system, such as, but not limited to a computer or communications system. For example, in one implementation, each of the items in a set of items has an associated deficit and mini-deficit. A next particular item is selected from the set of items currently having enough deficit to process the particular item. One or more entities associated with the particular item is processed a commensurate amount corresponding to the mini-deficit associated with the particular item. This processing is repeatedly performed until there are no more entities associated with the particular item or until the deficit associated with the particular item does not allow any further processing at the current time.

摘要： A method detects a change in TCP receive window size while preventing fragmentation of data. A TCP stack receives a segment that advertises a receive window size of zero. If data needs to be sent, and only if so, a timer is started. When the timer expires, a TCP segment that contains a first sequence number value equal to second sequence number representing sent but unacknowledged data minus one, and a segment length value of zero, is sent. Without sending a fragment of data, this triggers a peer TCP process to send an updated window size. A TCP ACK segment is received and contains an updated receive window size. If the updated receive window size is greater than a specified value, then the data is sent. Otherwise, a counter is incremented, and the steps are re-performed if the counter is less than a specified value.

摘要： A system and method supporting efficient, scalable stateful switchover of transport layer connections in a telecommunications network element. One method involves receiving, at a network element comprising an active transport protocol process coupled to a standby protocol process, a request to configure a first transport layer connection maintained at the active transport protocol process for stateful switchover; receiving an event associated with the first transport layer connection; creating a message containing replicated event information based on the received event; sending the message to the standby transport protocol process; and processing the message at the standby transport protocol process, wherein the standby transport protocol process replicates state information for the first connection.

摘要： A method for detecting unavailable network connections comprises, at a first data processing node that is hosting a transport protocol connection that uses a plurality of sequence values to identify messages sent to a peer node, wherein the first node is communicatively coupled to a second data processing node serving as a redundant backup, periodically sending a checkpoint sequence value to the second node; detecting that either the transport protocol connection or a process using the transport protocol connection is unavailable, without use of a timeout; and in response thereto, sending a notification to the peer node, wherein the notification includes the checkpoint sequence value. One embodiment provides for rapidly detecting and responding to failure of a TCP process without using long timeouts as conventionally provided in long-lived applications that run on top of TCP.
