In nonseamless mode, each Citrix application uses a separate TCP connection, and NBAR can be used to provide interapplication differentiation based on the name of the published application. Seamless mode clients can operate in one of two submodes: session sharing or nonsession sharing. Seamless sharing mode is enabled by default on some software releases. In seamless nonsession sharing mode, each application for each particular client uses a separate TCP connection.
NBAR can provide interapplication differentiation in seamless nonsession sharing mode. Pipelined Citrix ICA client requests are not supported. Citrix uses one TCP session each time an application is opened. In the TCP session, a variety of Citrix traffic may be intermingled in the same session. For example, print traffic may be intermingled with interactive traffic, causing interruption and delay for a particular application. Most people would prefer that printing be handled as a background process and that printing not interfere with the processing of higher-priority traffic.
When ICA traffic priority tag numbers are used, and the priority of the traffic is determined, QoS features can be implemented to determine how the traffic will be handled. For example, QoS traffic policing can be configured to transmit or drop packets with a specific priority. These bytes are not compressed or encrypted.
The first two bytes of the packet byte 1 and byte 2 contain the byte count and the ICA priority tag number. Byte 1 contains the low-order byte count, and the first two bits of byte 2 contain the priority tags. The other six bits contain the high-order byte count. The ICA priority tag value can be a number from 0 to 3. The number indicates the packet priority, with 0 being the highest priority and 3 being the lowest priority. To prioritize Citrix traffic by the ICA tag number of the packet, you specify the tag number using the ica-tag keyword and the ica-tag-value argument of the match protocol citrix command.
RTP is a packet format for multimedia data streams. It can be used for media-on-demand as well as for interactive services such as Internet telephony. RTP consists of a data and a control part. The data part of RTP is a thin protocol that provides support for applications with real-time properties such as continuous media audio and video , which includes timing reconstruction, loss detection, and security and content identification.
NBAR RTP Payload Type Classification not only allows one to statefully identify real-time audio and video traffic but can also differentiate on the basis of audio and video codecs to provide more granular QoS. NBAR supports the use of custom protocols to identify custom applications. Custom protocols support static port-based protocols and applications that NBAR does not currently support.
You can add to the set of protocols and application types that NBAR recognizes by creating custom protocols. Custom protocols extend the capability of NBAR Protocol Discovery to classify and monitor additional static port applications and allows NBAR to classify nonsupported static port traffic. Note For more information about specifying user-defined custom protocols, see the "Creating a Custom Protocol" module.
The following are the most common peer-to-peer file-sharing applications supported by NBAR:. The match protocol gnutella file-transfer regular-expression and match protocol fasttrack file-transfer regular-expression commands are used to enable Gnutella and FastTrack classification in a traffic class. In the following example, all FastTrack traffic is classified into class map nbar:.
Similarly, all Gnutella traffic is classified into class map nbar in the following example:. Wildcard characters in a regular expression can also be used to identify specified Gnutella and FastTrack traffic. These regular expression matches can be used to match on the basis of filename extension or a particular string in a filename.
In the following example, all Gnutella files that have the. In the following example, only Gnutella traffic that contains the characters "cisco" is classified:. RTSP is the protocol used for applications with steaming audio, such as the following:. The AutoQoS for the Enterprise feature allows you to automate the deployment of QoS in a general business environment, particularly for midsize companies and branch offices of larger companies.
The table also provides information about the protocol type, the well-known port numbers, the syntax for entering the protocol in NBAR, and the Cisco IOS release in which the protocol was initially supported. Many peer-to-peer file-sharing applications not listed in this table can be classified using FastTrack or Gnutella.
RTSP can be used to classify various types of applications that use streaming audio. Note Cisco currently supports Skype Version 1 only. This table is updated when a protocol is added to a new Cisco IOS release train. NBAR checks to see if more memory is required to handle additional concurrent stateful traffic flows.
Protocol Discovery provides an easy way to discover the application protocols that are operating on an interface. Custom protocols extend the capability of NBAR Protocol Discovery to classify and monitor additional static port applications and allow NBAR to classify nonsupported static port traffic. The following sections provide references related to classifying network traffic using NBAR. QoS commands: complete command syntax, command modes, command history, defaults, usage guidelines, and examples.

A high-speed, low-error data network that covers a relatively small geographic area up to a few thousand meters. LANs connect workstations, peripherals, terminals, and other devices in a single building or other geographically limited area. The standard for transmitting nontext data or data that cannot be represented in plain ASCII code in Internet mail, such as binary, foreign language text such as Russian or Chinese , audio, and video data. A switching method that forwards IP traffic using a label.
This label instructs the routers and the switches in the network where to forward the packets based on preestablished IP routing information. A command-line interface that allows you to define traffic classes, create and configure traffic policies policy maps , and then attach the policy maps to interfaces. The policy maps are used to apply the appropriate quality of service QoS to network traffic. A file that contains Packet Description Language statements used to define the signature of one or more application protocols.
Protocol Discovery provides a way to discover the application protocols that are operating on an interface. QoS —quality of service. A measure of performance for a transmission system that reflects its transmission quality and service availability. A means for enabling the controlled delivery of real-time data, such as audio and video. Sources of data can include both live data feeds, such as live audio and video, and stored content, such as prerecorded events.
A connection-oriented transport layer protocol that provides reliable full-duplex data transmission. UDP is a simple protocol that exchanges datagrams without acknowledgments or guaranteed delivery, requiring that error processing and retransmission be handled by other protocols. WAN —wide-area network. It is useful to see some of the traffic a NetBench run generates.

Anith Anand. They contain malformed traffic used to test the robustness of protocol implementations; they also test the robustness of protocol analyzers such as Wireshark. Apple AirTunes protocol as used by AirPort. This file contains a capture of proxy also called dummy multicast frames sent after a root port switchover on behalf of 3 dynamic unicast MAC addresses to update the "upstream" part of the network about the new path toward them.
For each of the MAC addresses d. The frame payload is just a stuffing to the minimal frame length; it has no meaning. Certificate key and Kerberos keytab included. The capture was made using the Samba4 smbtorture suite, against a Windows Vista beta2 server. Master Browser a elected by a list of criteria. The role of a master browser should be taken by a stable system, as browser elections can have a serious performance impact. This trace shows the a client with a misconfigured firewall, blocking incoming UDP port Since the client can not find a master browser, it stalls all other systems by repeated browser elections.
Clients can send a lock request. If necessary, the server has to break conflicting locks by sending a lock request to the client. This is a bit unusual: We see requests from the server. A large number of lock requests is usually an indicator for poor performance. If lock requests are made as blocking IOs, users will experience that their application freezes in a seemingly random manner. There are 4 subflows, 2 of them actually successfully connected. For instance try the filter "tcp.

The capture includes the frame check sequence at the end of each packet. This "capture" has been generated using text2pcap tool, from MTP3 raw data trace. The other difference is that the call is rejected. There aren't any complete dialogs in the capture. Really this should be in an "SS7" section of the SampleCaptures page. This "capture" has been generated using text2pcap tool, from RMCP raw data trace.

Each link state type has a separate advertise- ment format. It is used to detect old and dupli- cate link state advertisements. The space of sequence numbers is linearly ordered. The larger the sequence number the more recent the advertisement. The age field is excepted so that an advertisement's age can be incremented without updating the checksum. The checksum used is the same that is used for ISO connec- tionless datagrams; it is commonly referred to as the Fletcher checksum.
For example, class B address range of X. X with a network mask of By default, the area that a subsuming OSPF in- terface is in, or 0. By way of a default, this field may be intuited from the corresponding value of ifType. The value formed on the interface, and the in- terface will be advertised as an internal route to some area. The value 'disabled' denotes that the interface is external to OSPF. Used in multi-access networks, this field is used in the designated router election algorithm.
The value 0 signifies that the router is not eligi- ble to become the designated router on this particular network. In the event of a tie in this value, routers will use their Router ID as a tie breaker. This value is also used when retransmitting database descrip- tion and link-state request packets.
This value must be the same for all routers attached to a common network. This should be some multiple of the Hello interval. If the Area's Author- ization Type is simplePassword, and the key length is shorter than 8 octets, the agent will left adjust and zero fill to 8 octets. Note that unauthenticated interfaces need no authentication key, and simple password authen- tication cannot use a key of more than 8 oc- tets.
Larger keys are useful only with authen- tication mechanisms not specified in this docu- ment. Data link multicasting is not meaning- ful on point to point and NBMA interfaces, and setting ospfMulticastForwarding to 0 effective- ly disables all multicast forwarding.
Additional authentication types may be assigned locally. For multiple link interfaces, note -- that ifSpeed is the sum of the individual link speeds. On row creation, this can be derived from the in- stance. On row crea- tion, this can be derived from the instance. On row creation, this can be derived from the instance. By definition, this is not 0.
This value should be well over the expected round- trip time. This value must be the same for the virtual neighbor. This value must be the same for the virtual neigh- bor. When read, ospfVifAuthKey always returns a string of length zero. Note that, on addressless links, this will not be 0. If zero, the neighbor will ignore all metrics except the TOS 0 metric. Bit 1, if set, indicates that the associated area accepts and operates on external informa- tion; if zero, it is a stub area.
Bit 2, if set, indicates that the system is ca- pable of routing IP Multicast datagrams; i. Bit 3, if set, indicates that the associated area is an NSSA. These areas are capable of carrying type 7 external advertisements, which are translated into type 5 external advertise- ments at NSSA borders. The value 0 sig- nifies that the neighbor is not eligible to be- come the designated router on this particular network. The purpose is to allow external -- LSAs to be displayed once for the router rather -- than once in each non-stub area.
