Is QUIC a Better Choice Than TCP in the 5G Core Network Service Based Architecture?
DEGREE PROJECT IN INFORMATION AND COMMUNICATION TECHNOLOGY, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2020 Is QUIC a Better Choice than TCP in the 5G Core Network Service Based Architecture? PETHRUS GÄRDBORN KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCE Is QUIC a Better Choice than TCP in the 5G Core Network Service Based Architecture? PETHRUS GÄRDBORN Master in Communication Systems Date: November 22, 2020 Supervisor at KTH: Marco Chiesa Supervisor at Ericsson: Zaheduzzaman Sarker Examiner: Peter Sjödin School of Electrical Engineering and Computer Science Host company: Ericsson AB Swedish title: Är QUIC ett bättre val än TCP i 5G Core Network Service Based Architecture? iii Abstract The development of the 5G Cellular Network required a new 5G Core Network and has put higher requirements on its protocol stack. For decades, TCP has been the transport protocol of choice on the Internet. In recent years, major Internet players such as Google, Facebook and CloudFlare have opted to use the new QUIC transport protocol. The design assumptions of the Internet (best-effort delivery) differs from those of the Core Network. The aim of this study is to investigate whether QUIC’s benefits on the Internet will translate to the 5G Core Network Service Based Architecture. A testbed was set up to emulate traffic patterns between Network Functions. The results show that QUIC reduces average request latency to half of that of TCP, for a majority of cases, and doubles the throughput even under optimal network conditions with no packet loss and low (20 ms) RTT. Additionally, by measuring request start and end times “on the wire”, without taking into account QUIC’s shorter connection establishment, we believe the results indicate QUIC’s suitability also under the long-lived (standing) connection model. -

Ipv6 Security: Myths & Legends
IPv6 security: myths & legends Paul Ebersman – [email protected] 21 Apr 2015 NANOG on the Road – Boston So many new security issues with IPv6! Or are there… IPv6 Security issues • Same problem, different name • A few myths & misconceptions • Actual new issues • FUD (Fear Uncertainty & Doubt) Round up the usual suspects! Remember these? • ARP cache poisoning • P2p ping pong attacks • Rogue DHCP ARP cache poisoning • Bad guy broadcasts fake ARP • Hosts on subnet put bad entry in ARP Cache • Result: MiM or DOS Ping pong attack • P2P link with subnet > /31 • Bad buy sends packet for addr in subnet but not one of two routers • Result: Link clogs with routers sending packet back and forth Rogue DHCP • Client broadcasts DHCP request • Bad guy sends DHCP offer w/his “bad” router as default GW • Client now sends all traffic to bad GW • Result: MiM or DOS Look similar? • Neighbor cache corruption • P2p ping pong attacks • Rogue DHCP + rogue RA Solutions? • Lock down local wire • /127s for p2p links (RFC 6164) • RA Guard (RFC 6105) And now for something completely different! So what is new? • Extension header chains • Packet/Header fragmentation • Predictable fragment headers • Atomic fragments The IPv4 Packet 14 The IPv6 Packet 15 Fragmentation • Minimum 1280 bytes • Only source host can fragment • Destination must get all fragments • What happens if someone plays with fragments? IPv6 Extension Header Chains • No limit on length • Deep packet inspection bogs down • Confuses stateless firewalls • Fragments a problem • draft-ietf-6man-oversized-header-chain-09 -

Distributed Computing Characteristics of distributed computing: • Computers are independent — they do not share memory. • Coordination is enabled by messages passed across a network. • Individual programs have differentiating roles. Distributed computing for large-scale data processing: • Databases respond to queries over a network. • Data sets can be partitioned across multiple machines (next lecture). 4 Network Messages Computers communicate via messages: sequences of bytes transmitted over a network. Messages can serve many purposes: • Send data to another computer • Request data from another computer • Instruct a program to call a function on some arguments. Internet Protocol • Transfer a program to be executed by another computer. Messages conform to a message protocol adopted by both the sender (to encode the message) & receiver (to interpret the message). -
Manual Update Configuring a Default Gateway
S3290 Manual Update Configuring a Default Gateway The following information is to be included with the S3290 Web User Guide. IP Configuration Configure the S3290-managed IPv4 information from Configuration > System > IP as one of the first steps. The S3290 supports an IPv4 / IPv6 dual stack. The S3290 can be assigned IP address statically or dynamically using DHCP. Here you can configure IP basic settings, IP interfaces and IP routes. Up to 8 interfaces and up to 32 routes are supported. IP Routes Click the Add Route button to display the editable fields: Delete Select this option to delete an existing IP route. Network The destination IP network or host address of this route. Valid format is dotted decimal notation or a valid IPv6 notation. A default route can use the value 0.0.0.0 or IPv6 :: notation. Mask Length The destination IP network or host mask, in number of bits (prefix length). It defines how much of a network address that must match, in order to qualify for this route. Valid values are 0 - 32 bits for IPv4 routes or 0 - 128 for IPv6 routes. Only a default route will have a mask length of 0 (as it will match anything). Gateway The IP address of the IP gateway. Valid format is dotted decimal notation or a valid IPv6 notation. The Gateway and Network must be of the same type. It may be necessary to add a static route if a default gateway is required or if the device does not reside within the same network. Routing can then be enabled at System > IP > IP Configuration. -
Ipv6 – What Is It, Why Is It Important, and Who Is in Charge? … Answers to Common Questions from Policy Makers, Executives and Other NonTechnical Readers
IPv6 – What is it, why is it important, and who is in charge? … answers to common questions from policy makers, executives and other nontechnical readers. A factual paper prepared for and endorsed by the Chief Executive Officers of ICANN and all the Regional Internet Registries, October 2009. 1. What is IPv6? “IP” is the Internet Protocol, the set of digital communication codes which underlies the Internet infrastructure. IP allows the flow of packets of data between any pair of points on the network, providing the basic service upon which the entire Internet is built. Without IP, the Internet as we know it would not exist. Currently the Internet makes use of IP version 4, or IPv4, which is now reaching the limits of its capacity to address additional devices. IPv6 is the “next generation” of IP, which provides a vastly expanded address space. Using IPv6, the Internet will be able to grow to millions of times its current size, in terms of the numbers of people, devices and objects connected to it1. 2. Just how big is IPv6? To answer this question, we must compare the IPv6 address architecture with that of IPv4. The IPv4 address has 32 bits, allowing today’s Internet to connect up to around four billion devices. By contrast, IPv6 has an address of 128 bits. Because each additional bit doubles the size of the address space, an extra 96 bits increases the theoretical size of the address space by many trillions of times. For comparison, if IPv4 were represented as a golf ball, then IPv6 would be approaching the size of the Sun.2 IPv6 is certainly not infinite, but it is not going to run out any time soon. -
