Overview

Technical background

Data center technologies have developed fast in recent years. However, little attention has been paid to traffic management and fault monitoring in data centers. Due to lack of automated O&M tools, the large scale of data centers poses great challenges to data center O&M.

In traditional networks, radar detection is typically used to detect forwarding paths. Radar detection requires the involvement of controller software. Controller software has complex design and implementation, and cannot fully emulate packet forwarding.

Although ping and tracert operations can identify the network delay and path, they cannot identify on which port of which device packets are forwarded with the longest delay. As an important part of visibility technologies, Inband Network Telemetry (INT) is the first and most important step for driving O&M automation. INT allows you to obtain the following information on the forwarding path:

·     Device information.

·     Ingress port, egress port, ingress queue, and egress queue of packets on each device.

·     Ingress timestamp and egress timestamp.

Benefits

INT provides visibility into the following information on the forwarding path:

·     Ingress port, egress port, ingress queue, and egress queue of packets on each device.

·     Ingress timestamp and egress timestamp.

·     Queue congestion information.

On the last hop in the forwarding path, INT can encapsulate the UDP header and IP header for a monitored flow and sends the packets to the collector. Finally, the NMS on the collector analyzes the monitored flow and extracts useful information.

INT has the following benefits:

·     Full hardware support.

·     One configuration deployment, continuous data reporting.

·     Defining original packets to be monitored by using QoS policies.

·     Encapsulating packets on the last hop of the path and sending them to the collector.

·     Collecting device information, interface information, queue information, timestamp information, and forwarding path information for each device.

Protocols and standards

INT 1.0

The Internet Draft Inband Flow Analyzer draft-kumar-ifa-00 has been submitted to IETF. This draft describes the formats of the INT header and metadata in detail. Theoretically, network devices that support this draft can implement INT packet analysis and processing functions.

INT 2.0

INT 2.0 is defined in the Internet Draft Inband Flow Analyzer draft-kumar-ifa-02. INT 2.0 supports TCP- and UDP-based INT packets, and does not support VXLAN packets or IPv6 packets with extension headers.

INT 1.0 implementation

Concepts

·     Entry node

The entry node samples packets and mirrors sampled packets to the INT processor, adds an INT header and metadata to the packets, and sends them to the transit node.

·     Transit node

The transit node identifies INT packets, adds metadata to the INT packets, and sends them to the exit node.

·     Exit node

As the last hop in an INT network, the exit node identifies INT packets, adds metadata to the INT packets, encapsulates the UDP header and IP header for the INT packets, and sends them to the collector.

·     Ingress port

For the entry node, this port is the input interface of original packets. For the transit node and exit node, this port is the input interface of INT packets.

·     Egress port

For the entry node and transit node, this port is the output interface of INT packets. For the exit node, this port is the output interface of encapsulated packets.

·     INT processor

The INT processor is a dedicated processor in the CPU used for processing INT packets. For the mirrored packets on the entry node, the INT processor adds an INT header to generate INT packets. On the exit node, the INT processor performs consistency checks on the encapsulation format of metadata and encapsulates the outer UDP header for the INT packets.

Metadata that INT can collect

INT can collect and monitor the following metadata:

·     Device ID.

·     Ingress port ID—Logical input interface of packets.

·     Ingress timestamp—The local time on the device when a packet enters the ingress port. For the entry node, it is the time when an INT packet enters the loopback interface.

·     Egress port ID—Logical output interface of packets

·     Egress timestamp—The local time on the device when a packet leaves the egress port.

·     Cache information:

¡     Queue ID—ID of the queue that caches original packets.

¡     ECN information.

INT packet types and packet formats

Packet types

INT has two packet types: INT over TCP and INT over UDP.

An original TCP packet is called an INT-over-TCP packet after it is mirrored and inserted with an INT header.

An original UDP packet is called an INT-over-UDP packet after it is mirrored and inserted with an INT header.

Figure 2 INT over TCP/UDP

 

The following explains the meanings of related fields:

·     INT Probe HDR—Header inherent to INT.

·     Termination Function Metadata—Data collected on the exit node.

·     Transit Function hop 0-N Metadata—Data collected on the transit node.

·     Initiating Function Metadata—Data collected on the entry node.

Packet formats

An INT header contains two parts: an inherent header and metadata.

Figure 3 shows the format of the inherent header.

Figure 3 Inherent header format

 

The following explains the meanings of the fields:

·     Probe Marker—Used by the device to identify INT packets. Its value is fixed at 0xaaaaaaaabbbbbbbb.

·     Version—Currently fixed at 0x01.

·     Message Type—Currently fixed at 0x01.

·     Flags—A reserved field, currently fixed at 0x0000.

·     Telemetry Request Vector—Currently fixed at 0xffffffff.

·     Hop Limit—Maximum number of hops allowed.

·     Hop Count—Number of nodes the packet has traversed.

·     Maximum Length—Maximum length of metadata that can be collected, in bytes.

·     Current Length—Length of metadata that has been collected, in bytes.

·     Sender's Handle—Set by the entry node for the collector to identify an INT flow and uniquely identifies an INT flow.

·     Sequence Number—Sequence number of packet in an INT flow.

Figure 4 shows the format of the metadata.

Figure 4 Inherent header format

 

The following explains the meanings of the fields:

·     Template-Id—A reserved field, currently fixed at 000.

·     Congestion—Indicating the congestion state. The three most significant bits are fixed at 000, and the two least significant bits are the ECN field.

·     Egress Port Drop Pkt Byte Cnt Upper—Drop count in bytes for the egress port, currently fixed at 0x00.

·     IP_TTL—TTL value.

·     Queue-Id—Egress queue ID, currently fixed at 0x00. The exit node does not support carrying queue ID. On the exit node, this field carries the traffic class information.

·     Rx Timestamp Seconds Upper/Rx Timestamp Seconds— Ingress timestamp in seconds.

·     Rx Timestamp Nano-Seconds Upper—Ingress timestamp in nanoseconds.

·     Tx Timestamp Nano-Seconds Upper—Egress timestamp in nanoseconds.

·     Egress Port Utilization [%]—Egress port utilization in percentage, currently fixed at 0x0000.

·     Ingress Port [module, port]—Ingress port.

·     Egress Port [module, port]—Egress port.

·     Egress Port Drop Pkt Byte Cnt—Drop count in bytes for the egress port, currently fixed at 0x00000000.

Mechanism

INT-capable devices form an INT zone. Each INT device performs different functions in the INT zone.

·     Entry node—By using a QoS policy on the ingress port, the entry node classifies incoming traffic and mirrors classified traffic to the INT processor. The INT processor adds the inherent INT header to matching packets, and adds metadata, and forwards the packets by looking up the routing table.

·     Transit node—The transit node automatically identifies INT packets, adds metadata to them, and forwards them by looking up the routing table.

·     Exit node—The transit node automatically identifies INT packets, sends the INT packets to the INT processor, and performs the following actions on the packets:

¡     Adds metadata.

¡     Encapsulates the outer UDP header for the INT packets.

¡     Encapsulates the outer IP header for the INT packets by using the configured encapsulation parameters.

¡     Routes the packet to the collector according to the destination IP address in the outer IP header.

Restrictions

Only the following switch series support INT:

·     S6850.

·     S9820.

·     S9850.

·     S6805.

·     S6825.

·     S12500X-AF T.

The following restrictions apply when you use INT on these switch series:

·     The S9820 and S12500X-AF T switch series can act as only transit nodes.

·     The S6850, S9850, S9820, S6805, and S6825 switch series can act as entry nodes, transit nodes, and exit nodes.

·     If an S9850 switch acts as an entry node, you must enable internal loopback on an interface in the same port group as the ingress port. The interface enabled with internal loopback cannot be used for other purposes or configured with other settings. For port grouping conventions, execute the display drv system 9 command in probe view. Interfaces of the same pipe are in the same port group.

·     For the mappings between ports on the front panel and the Ingress/Egress Port IDs in metadata, see Appendix.

Concepts

·     Entry node

The entry node samples packets and mirrors sampled packets to the internal loopback interface, adds an INT header and metadata to the packets, set the protocol number of packets to 253, and sends them to the transit node.

·     Transit node

The transit node identifies INT packets, adds metadata to the INT packets, and sends them to the exit node.

·     Exit node

As the last hop in an INT network, the exit node identifies INT packets, adds metadata to the INT packets, encapsulates the UDP header and IP header for the INT packets, and sends them to the collector.

·     Ingress port

For the entry node, this port is the input interface of original packets. For the transit node and exit node, this port is the input interface of INT packets.

·     Egress port

For the entry node and transit node, this port is the output interface of INT packets. For the exit node, this port is the output interface of encapsulated packets.

Metadata that INT can collect

INT can collect and monitor the following metadata:

·     Device ID.

·     Ingress port ID—Logical input interface of packets.

·     Ingress timestamp—The local time on the device when a packet enters the ingress port. For the entry node, it is the time when an INT packet enters the loopback interface.

·     Egress port ID—Logical output interface of packets

·     Cache information:

¡     Queue ID—ID of the queue that caches original packets.

¡     ECN information.

INT packet types and packet formats

Packet types

INT has two packet types: INT over TCP and INT over UDP.

An original TCP packet is called an INT-over-TCP packet after it is mirrored and inserted with an INT header.

An original UDP packet is called an INT-over-UDP packet after it is mirrored and inserted with an INT header.

Figure 6 INT over TCP/UDP

 

The following explains the meanings of related fields:

·     IFA Header—INT header.

·     IFA Metadata Header—INT metadata header.

·     Termination Function Metadata—Data collected on the exit node.

·     Transit Function hop 0-N Metadata—Data collected on the transit node.

·     Initiating Function Metadata—Data collected on the entry node.

Packet formats

IFA header

Figure 7 shows the format of the 4-byte IFA header.

Figure 7 IFA format

 

The following explains the meanings of the fields:

·     Version—Currently fixed at 0x2.

·     GSN—Global Name Space. This field indicates the metadata type and is fixed at 0xF, which indicates local metadata.

·     Next Header—This field is copied from the original packet.

·     Flags

¡     Reserved (3 bits)—Reserved field, which can only be 0.

¡     Metadata Fragment (1 bit)—Indicates the presence of the optional metadata fragment header. This field is fixed at 0, which indicates that the metadata fragment header is not present.

¡     Tail Stamp (1 bit)—Indicates the location of the IFA metadata header. This field is fixed at 0, which indicates that the IFA metadata header is behind the Layer 4 header.

¡     Inband (1 bit)—Indicates whether the packet is an original packet or a copied packet. This field is fixed at 1, which indicates that the packet is a copied packet. The exit node will discard the packet after sending the collected data to the collector.

¡     Turn Around (1 bit)—Indicates whether the exit node will send the packet back to the source IP address. This field is fixed at 1, which indicates that the exit node will not send the packet back to the source IP address.

¡     Checksum (1 bit)—Indicates the presence of the optional checksum header. This field is fixed at 1, which indicates that the optional checksum header is not present.

·     Max Length (8 bits)—Maximum length of metadata that can be collected, in multiples of 4 bytes.

IFA metadata header

Figure 8 shows the format of the IFA metadata header.

Figure 8 IFA metadata header

 

The following explains the meanings of the fields:

·     Request Vector—Controls whether a node can add metadata. This field is not supported in the current software version and is fixed at 0.

·     Action vector—Indicates the action type of a node. This field is not supported in the current software version and is fixed at 0.

·     Hop Limit—Indicates the maximum of nodes that can add metadata. Similar to the TTL in IP packets, this field can be used to prevent loops. This field is initialized to 20 by the entry node and is decremented at each hop. When a node receive a packet with a hop limit of 0, it will not add metadata. When this field is 0xFF, a node does not examine or modify this field, and the number of hops is not limited.

·     Current length—Specifies the current length of the metadata, in multiples of 4 bytes.

Metadata

Figure 9 shows the format of the metadata.

Figure 9 Metadata

 

The following explains the meanings of the fields:

·     LNS—Local Name Space. This field is fixed at 0xF.

·     Device ID.

·     IP TTL—TTL value.

·     EPS—Egress Port Speed. The S9825 switch series does not support this field. The following values are supported:

¡     0—10 Gbps.

¡     1—25 Gbps.

¡     2—40 Gbps.

¡     3—50 Gbps.

¡     4—100 Gbps.

¡     5—200 Gbps.

¡     6—400 Gbps.

·     C—Congestion, or ECN. The higher three bits are fixed at 0, and the lower two bits are the ECN field.

·     Queue ID—Queue ID of the egress port.

·     RX Timestamp Seconds—Device startup time.

·     Egress System Port.

·     Ingress System Port.

·     Rx Timestamp Nanosecond—Ingress port timestamp in nanoseconds.

·     Residence Time(nanoseconds)—Delay of the packet on a node, in nanoseconds.

·     Queue Transmit Byte Count—This field is not supported in the current software version.

·     Reserved—Reserved field, which is fixed at 0.

·     Queue Depth—Indicates the amount of the buffer that is used by the queue.

·     MMU Stats—Indicates the amount of the free buffer. For the S9825 switch series, bits 23 through 21 of this field are fixed at 3 (011).

Packets sent by the exit node to the collector

The exit node adds metadata, IPFIX header, UDP header, and Layer 3 header to the INT packet, and forwards the INT packet according to the destination IP address in the Layer 3 header.

Mechanism

INT-capable devices form an INT zone. Each INT device performs different functions in the INT zone.

·     Entry node—By using a QoS policy on the ingress port, the entry node classifies incoming traffic and mirrors classified traffic to the internal loopback interface. The device adds an INT header to matching packets, adds metadata, set the IP protocol number to 253, and forwards the packets by looking up the routing table.

·     Transit node—The transit node automatically identifies INT packets, adds metadata to them, and forwards them by looking up the routing table.

·     Exit node—The transit node automatically identifies INT packets, sends the INT packets to the internal loopback interface, and performs the following actions on the packets:

¡     Adds metadata.

¡     Encapsulates the outer UDP header for the INT packets.

¡     Encapsulates the outer IP header for the INT packets by using the configured encapsulation parameters.

¡     Routes the packet to the collector according to the destination IP address in the outer IP header.

Restrictions

Only the following S9855 and S9825 switch series support INT 2.0. An S9825 switch can only act as a transit node. An S9855 switch can act as an entry node, transit node, or exit node.
