UE User Equipment for LTE URLLC Ultra Reliable Low Latency Communications VM Virtual Machine 4 Overview The Next Generation Protocols (NGP), ISG aims to review the future landscape of Internet Protocols, identify and document future requirements and trigger follow up a
32、ctivities to drive a vision of a considerably more efficient Internet that is far more attentive to user demand and more responsive whether towards humans, machines or things. ETSI GS NGP 001 1, Scenarios Descriptions specification, lists the key agreed networking and internetworking issues for mult
33、i-access communications at present and provides examples of current scenarios where these issues are exemplified. ETSI GS NGP 001 1 further provides recommendations, on a per issue basis, targeted at applicable next generation SDOs: ITU-T, IEEE, IETF and 3GPP in their consideration of future network
34、ing and internetworking protocol architecture definitions. The present document progresses the requirements decomposition process one further stage to define key requirements for NGP. The present document provides key general NGP requirements, in clause 5 and NGP issue specific requirements, in clau
35、se 6. 5 General Requirements 5.1 Business Case Gen-BC-01 The NGP architecture shall be 25 % more energy efficient across end-user devices, servers, fixed transmission and access technologies and wireless and/or cellular access technologies as compared to existing IPv4/v6 protocol based architectures
36、. NOTE 1: This performance measure should be based on network wide measurements and devices connecting with reference access technologies current at the time of specification as follows: LTE-A, Rel-12, Wi-Fi 802.11ac and Ethernet 100 Mbit/s FE. ETSI ETSI GS NGP 005 V1.1.1 (2017-04)8 Gen-BC-02 The NG
37、P architecture shall be 30 % more spectrally efficient when transporting NGP across the access technology as compared to transporting existing IPv4/v6 protocol based architectures and considering all over-air impacting facets. Gen-BC-03 The NGP architecture shall be at least 25 % more header efficie
38、nt than existing IPv4/v6 protocol based architectures. Gen-BC-04 The NGP architecture shall be at least 10 % more bitwise efficient per packet than existing IPv4/v6 protocol based architectures for the same application transport. NOTE 2: The scope of Gen-BC-02x requirements is from the UE or NG-UE t
39、o the edge of Operator Domain connecting to the Internet or other external PDN. NOTE 3: Gen-BC-02(x) performance measures should be based on reference radio-based access technologies current at the time of specification as follows: LTE-A, Rel-12, Wi-Fi 802.11ac. Gen-BC-05 The NGP architecture shall
40、be able to be cost effectively implemented into existing user device operating systems with no additional processor or memory requirements, as compared to IPv4/6 implementations. NOTE 4: Current key user device, operating systems should include Android, iOSand Windows. Gen-BC-06 The NGP architecture
41、 shall be able to be cost effectively implemented into existing user server operating systems with no additional processor or memory requirements, as compared to IPv4/6 implementations. NOTE 5: Current key server operating systems should include Linux variants and Windows. Gen-BC-07 The NGP architec
42、ture shall be able to be cost effectively implemented into network interface software and hardware, with no additional processor or memory requirements. as compared to IPV4/6 implementations. NOTE 6: Current implementations should include: Custom Integrated Circuits (IC), Field Programmable Gate Arr
43、ay (FPGA) technology solutions and software defined, Network Interface Cards (NIC). 5.2 Migration Gen-Mig-01 The NGP architecture shall be able to provide peer to peer communications between a next generation access communications device and the edge of that access network or networks with no increa
44、se in setup delay as compared to existing IPv4/v6 protocol based architectures, for the issues described in ETSI ETSI ETSI GS NFV 001 i.5 and when operating over LTE-A, Rel-12 access technology. NOTE 1: An access communications device may include an evolved 3GPP UE, server or IoT device and the acce
45、ss network may include millimetric radio, cellular, wireless and/or fixed connectivity. NOTE 2: Access efficiency in this context may be: spectrum efficiency, bitwise efficiency, or byte efficiency of the protocol. Gen-Mig-02 The NGP architecture shall be able to interwork to the existing IPv4 and I
46、Pv6 protocol. Gen-Mig-03 The NGP architecture shall be able to support transmission of the 3GPP TR 23.799 i.1 defined interfaces: NG1, NG2, NG3 NG4 and NG6, interfaces at layer 3. 5.3 Technical Gen-Tech-01 NGP shall support multi-level mutual authentication between peers. NOTE 1: Authentication is o
47、perated between peer entities. NOTE 2. Authentication among applications only involves the applications, not NGP. NOTE 3: Authentication within NGP is among the entities supporting NGP itself. ETSI ETSI GS NGP 005 V1.1.1 (2017-04)9 NOTE 4: NGP should require the authentication of all members of a gi
48、ven layer. Gen-Tech-02 NGP shall not allow third parties (other than those authorized by law, such as national security agencies) to discover the identity of entities that are communicating with each other. Gen-Tech-03 NGP shall provide stakeholder based confidentiality for user data. Gen-Tech-04 NG
49、P shall provide stakeholder based confidentiality for protocol control. NOTE 5: For Gen-Tech-03x: A stakeholder would typically include N x communicating peers. NOTE 6: For Gen-Tech-03x: A stakeholder agreement could optionally include an N+1 party as well as the peers (e.g. Operator and/or Lawful Intercept party. 6 Issue Specific Requirements 6.1 Addressing Iss-Addr-01 In a multi-access and multi-layer, context aware NGP environment future protocols should address ID an
