What are the methods for packet processing on Linux? And how fast are each packet processing methods? In this presentation, we will learn how to handle packets on Linux (User space, socket filter, netfilter, tc), and compare performance with analysis of where each packet processing is done in the network stack (hook point). Also, we will discuss packet processing using XDP, an in-kernel fast-path recently added to the Linux kernel. eXpress Data Path (XDP) is a high-performance programmable network data-path within the Linux kernel. The XDP is located at the lowest level of access through SW in the network stack, the point at which driver receives the packet. By using the eBPF infrastructure at this hook point, the network stack can be expanded without modifying the kernel.

You can click the Show Lab Content button to download the lab or you can download the l ab from
[email protected] in Content.
VLAN, Trunk and 802.1q Router Configuration
Step 1: Initial Switch Configuration
Configure hostnames on the switches
Configure enable secret, console and vty (Telnet) passwords as uwstout
Configure VLANs 10, 20 and 30 on StoutSW1 and StoutSW2
Configure the ports the PCs are connected to in the proper vlans
Shutdown the fa0/4 interfaces on each switch
Configure an IEEE 802.1Q trunk between StoutSW1 and StoutSW2 using the fa0/1 interfaces
Configure the IP addresses and subnet masks on PC1a, PC1b and PC2 according to the topology
diagram
Verify your configuration before moving on to Step 2
If you need help remembering the commands for the initial configuration steps, try using ? or refer to the
previous labs.
Before moving to Step 2 verify your trunk and VLAN configuration, PC IP addresses and that the switchports
for the PCs are in the correct vlans. Use “show” commands and ipconfig to verify the initial configuration.
VLAN, Trunk and 802.1q Router Configuration
Step 2: Configure 802.1 trunk between Menomonie and StoutSW1
Data from one vlan cannot cross into another vlan without the help of a router to route the data. Currently
the PCs cannot successfully send to each other because they are on different VLANs. In this step you will
configure a trunk between the Menomonie router and the StoutSW1 switch. (This type of configuration is
referred to as “Router-on-a-Stick”) so the router can be used to route traffic between the VLANs. The
physical interface on the router that is connected to StoutSW1 is fastethernet0/1 so you will configure the
trunked sub-interfaces on the fastethernet0/1 interface. Then configure fastethernet0/8 on StoutSW1 to trunk.
Configure the Router:
Configure the hostname on the router to Menomonie:
In global configuration mode type, hostname Menomonie
Configure the first sub-interface on Menomonie to route vlan 10
In global configuration mode type, interface fastethernet0/1.10
In interface configuration mode for fa0/1.10 type, encapsulation dot1q 10
Configure the second sub-interface on Menomonie to route vlan 20
In global configuration mode type, interface fastethernet0/1.20
In interface configuration mode for fa0/1.20 type, encapsulation dot1q 20
Configure the third sub-interface on Menomonie to route vlan 30
In global configuration mode type, interface fastethernet0/1.30
In interface configuration mode for fa0/1.30 type, encapsulation dot1q 30
Now that the virtual trunked interfaces have been configured you can assign an IP address to the
interfaces. The addresses for each inter ...

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

How to add and delete ont on the olt device
1. How to Add and Delete ONT on the OLT Device
1 How to add an ONT on the OLT device
The Huawei ONT is connected to the GPON port of the OLT through optical fibers. The
service can be configured only after an ONT is successfully added on the Huawei OLT.
Two ONTs are connected to GPON port 0/1/1. The ONT IDs are 1 and 2, the SNs are
6877687714852900 and 6877687714852901, the management mode is OMCI, and ONT
line profile 10 and service profile 10 are bound to the two ONTs.
(1) Add an ONT offline.
If the password or SN of an ONT is obtained, you can run the ONT add command to add
the ONT offline.
huawei(config)#interface gpon 0/1
huawei(config-if-gpon-0/1)#ont add 1 1 sn-auth 6877687714852900 omci ont-
lineprofile-id 10 ont-srvprofile-id 10
huawei(config-if-gpon-0/1)#ont add 1 2 sn-auth 6877687714852901 omci ont-
lineprofile-id 10 ont-srvprofile-id 10
(2) Automatically find an ONT.
If the password or SN of an ONT is unknown, run the port portid ont-auto-
find command in the GPON mode to enable the ONT auto-find function of the GPON
port. Then, run the ont confirm command to confirm the ONT.
huawei(config)#interface gpon 0/1
huawei(config-if-gpon-0/1)#port 1 ont-auto-find enable
huawei(config-if-gpon-0/1)#display ont autofind 1
//After this command is executed, the information about all ONTs connected to
the GPON port through the optical splitter is displayed.

ont-lineprofile-id 10 ont-srvprofile-id 10
NOTE:
If multiple ONTs of the same type are connected to a port and the same line profile or
service profile is bound to the ONTs, you can add ONTs in batches by confirming the auto
discovered ONTs in batches to simplify the operation and increase the configuration
efficiency. For example, the preceding command can be modified as follows:
huawei(config-if-gpon-0/1)#ont confirm 1 all sn-auth omci ont-lineprofile-id 10 ont-
srvprofile-id 10
a. (Optional) Bind an alarm profile to the ONT.
In this example, bind the default alarm profile, namely alarm profile 1 to the ONT.
huawei(config-if-gpon-0/1)#ont alarm-profile 1 1 profile-id 1
huawei(config-if-gpon-0/1)#ont alarm-profile 1 2 profile-id 1
2. Confirm that the ONT goes online normally.
After an ONT is added, run the display ont info command to query the current status of
the ONT. Ensure that Control flag of the ONT is active, Run State is online, Config
state is normal, and Match state is match.
huawei(config-if-gpon-0/1)#display ont info 1 1
---------------------------------------------------------------------
F/S/P : 0/1/1
ONT-ID : 1
2
3. Control flag : active //Indicates that the ONT is activated.
Run state : online //Indicates that the ONT goes online normally.
Config state : normal //Indicates that the configuration status of the
ONT is normal.
Match state : match //Indicates that the capability profile bound to
the ONT is consistent with the actual capability
of the ONT.
...//The rest of the response information is omitted.
If the ONT state fails, the ONT fails to be in the up state, or the ONT does not match,
check the ONT state by referring to the above-mentioned descriptions.
If Control flag is deactive, run the ont activate command in the GPON port mode to
activate the ONT.
If the ONT fails to be in the up state, that is, Run state is offline, the physical line may
be broken or the optical transceiver may be damaged. You need to check both the
material and the line.
If the ONT state fails, that is, Config state is failed, the ONT capability set outmatches
the actual ONT capabilities (For details about the ONT actual capabilities, see Reference
of GPON ONT Capability Sets). In this case, run the display ont failed-
configuration command in the diagnosis mode to check the failed configuration item and
the failure cause. Then, rectify the fault according to actual conditions.
NOTE:
If an ONT supports only four queues, the values of 4–7 of the priority-queue
parameter in the gem add command are invalid. After configuration recovers, Config
state will be failed.
If the ONT does not match, that is, Match state is mismatch, the port types and number
of ports undermatch the actual port types and number of ports supported by the ONT. In
this case, run the display ont capability command to query the actual capability of the
ONT, and then select one of the following modes to modify the ONT configuration:
Create a proper ONT profile according to the actual capability of the ONT, and then run
the ont modify command to modify the configuration data of the ONT.
Modify the ONT profile according to the actual capability of the ONT and save the
modification. Then, the ONT automatically recovers the configuration successfully.
3
4. 2 How to delete an ONT on OLT Device
This command is used to delete an ONT. The ONT configuration data is deleted with the
deletion of the ONT and the online ONT is forced offline. If the ONT configuration such as
the bound capability set profile and the authentication mode is incorrect, you can run this
command to delete the ONT, and then you can add it again.
Parameters
Parameter Description Value
portid Indicates the number of the
GPON port where the ONT to be
deleted is located.
Numeral type. Range:
varies with the board
type.
all Deletes all ONTs at a specified
GPON port. When you need to
delete ONTs in batches, use this
parameter.
-
ontid Indicates the number of the ONT
to be deleted. When you need to
delete a specified ONT, use this
parameter.
Numeral type. Range:
For GPBD: 0-127. For
other PON board: 0-63.
Usage Guidelines
• Run the config command to enter global config mode, and then run the interface
gpon command to enter GPON mode.
• An ONT cannot be deleted when it has been bound with a T-CONT profile, that is,
it has been configured with services. To delete it, run the tcont bind-profile
command to cancel its binding with the T-CONT profile.
Example
To delete ONT 2 on GPON port 0/3/0, do as follows:
huawei(config-if-gpon-0/3)#ont delete
{ portid<U><0,7> }:0
{ all<K>|ontid<U><0,127> }:2
Command:
ont delete 0 2
4
5. Number of ONTs that can be deleted: 1, success: 1
To delete all ONTs that has not been configured with services on GPON port 0/3/0, do as
follows:
huawei(config-if-gpon-0/3)#ont delete
{ portid<U><0,7> }:0
{ all<K>|ontid<U><0,127> }:all
Command:
