    摘要: A method is disclosed for simulating a load on an application server in a network. The method intercepts data packets of a request from a sender to a receiver. The data packets to be intercepted can be selected according to specified criteria, such as communications protocol or port and address information of the sender and/or receiver. A simulation session can begin and end based on a specified period of time or after a specified number of data packets have been received. The intercepted data packets are stored in a buffer and the time of arrival of the data packets is recorded. The data packets are held in the buffer for a user specified delay time. Upon expiration of the delay time, the data packets are forwarded to the receiver. Alternately, the method can operate bi-directionally, or by intercepting and delaying data packets of a response of the receiver sent to the sender.

    摘要: A method and apparatus for performing load-based packet marking within a network is described. In one aspect, a first group of one or more packets of a data flow are marked with a first behavioral treatment value that directs devices within the network to treat the first group of one or more packets with a first quality of service treatment. The bandwidth that is currently being achieved for the flow within the network is determined based on data traffic within the network. Based on the achieved flow bandwidth within the network a second behavioral treatment value is then determined. Thereafter, a second group of one or more packets of the data flow is marked with a second behavioral treatment value that directs devices within the network to treat the second group of one or more packets with a second quality of service treatment. The process of dynamically marking the packets for a particular data flow may be performed multiple times.

    摘要: A method, apparatus, and computer-readable medium configured for maintaining consistent per-hop packet forwarding behavior among a plurality of network devices in a network within a Differentiated Services (DS) domain are disclosed. In one aspect, a method involves creating and storing a network-wide PHB definition that associates a PHB with a DS code point (DSCP) value, and with a set of parameters that define the bandwidth and buffer resources allocated to the PHBs on all interfaces of network devices within the DS domain. A mapping of each of the PHBs in the network-wide PHB definition to one or more queues of the network devices is determined. Drain size and queue size values are determined for each of the queues to which PHBs are mapped. A mapping of each of the PHBs to a threshold value associated with the queues is determined. Parameters of fragmentation and interleave mechanisms are determined. Network device configuration parameter values based on the mappings, the drain size, and the queue size, etc. are sent to each of the network devices within the DS domain. As a result, consistent PHB is achieved throughout a network using abstract definitions of PHBs.

    摘要: A method and apparatus for adaptively enforcing Quality of Service (QoS) policies for one or more flows of packets in a packet-switched network based on network feedback information. In one aspect, packets of a first group of flows are assigned to a first service level. Then-current interface congestion information for network traffic that is mapped to the first service level and that is passing through an interface of a network device in the network is received. Based on the then-current interface congestion information one or more flows from the first group of flows are selected. Packets from the one or more flows are then assigned to a second service level.

    摘要: Verifying revocation status of a digital certificate is provided in part by a receiver verifying a security certificate for a sender. In an embodiment, an approach comprises receiving a first security certificate associated with the sender and storing the security certificate in a location accessible to the receiver; updating the first security certificate in the location accessible to the receiver if the first security certificate is changed or revoked; receiving a second security certificate from the sender when identity of the sender needs to be verified; comparing the second security certificate to the first security certificate; and confirming the sender's identity only if the second security certificate matches the first security certificate for the sender.

    摘要: A method is disclosed for authenticating multiple network elements that access a network through a single network switch port. Certain authentication protocols, such as EAPoE, leave a port of a network switch indefinitely opened when one particular host is authenticated and authorized to transmit network frames through the port. In one embodiment of the invention, a network frame from a second host that is received by the open port is not automatically transmitted to the network. Instead, techniques are employed locally by the network switch to grant or deny transmission of the network frame received from the second host. An authentication server is contacted only when the network switch cannot locally employ techniques to authorize the transmission of the network frame received from the second host.

    摘要: A method and an apparatus are disclosed for securing authentication, authorization and accounting (AAA) protocol messages. An encryption key, a device identifier value, and verification data are received and stored at a network device. The verification data comprises in part a copy the encryption key and the device identifier value, and has been encrypted using a private key of a server. A shared secret is generated by applying a computational function to the encryption key and the device identifier value. Based on the shared secret, a first message integrity check value for a message is generated. The message, the first integrity check value, and the verification data are sent to the server. The server decrypts the verification data using the private key, extracts the encryption key and the device identifier value, and generates the same shared secret by applying the same computational function to the extracted encryption key and device identifier value. Based on this generated shared secret, a second message integrity check value is generated and compared to the received first message integrity check value.
