Посоветуйте ethernet switch

Добрый день, UANOG. Посоветуйте ethernet свич под задачу: нужно агрегировать сервера (24 gigabit ethernet порта) в 10G SFP+. При этом нужно на 10G порту иметь простой пакетный фильтр на скорости порта, типа tcp/80 можно, а udp/123 допустим нет, а IP 4.4.4.4 можно все. Спасибо. -- Sergey Smitienko

защита ethernet от наводок?
by Vladimir Litovka 04 Mar '14

04 Mar '14

Привет, вопросик есть. Для домашней проводки купил ethernet-кабель с хорошим экранированием. Маркировки не помню, но он сильно толще аналогов и продавался именно как экранированный для защиты от электрических наводок. Спокойный в связи с этим, провел этот кабель в нескольких (4-6) сантиметрах от блока розеток и тем не менее порт в маршрутизаторе, куда включен этот кабель, склеил ласты. Вопрос - это может быть из-за близости к блоку розеток (вставление-вытаскивание штекеров, наверное, выдает в эфир наводки повышенной мощности?) и поможет-ли в дальнейшем использование электрической защиты ethernet-портов? Если да - то посоветуйте, какие и где их купить в Киеве и совместима-ли защита 1000TX с режимом работы 100TX? (в смысле - с одной стороны - 1000BaseTX, с другой - 100BaseTX и негошиируют они, соответственно, на скорости 100M). Спасибо. -- /doka

OpenDaylight Launches Open-Source SDN Controller Platform
by Vladimir Litovka 15 Feb '14

15 Feb '14

Сори за слегка спам, это чуток больше деталей к предыдущему письму - SAN FRANCISCO -- The OpenDaylight Project, a community-led and industry-supported open source platform to advance software-defined networking (SDN) and network functions virtualization (NFV), today announced that its first open source software release “Hydrogen” is available for download. OpenDaylight is an open platform for network programmability to enable SDN and create a solid foundation for NFV for networks at any size and scale. Enterprises, service providers, equipment providers and academia can download Hydrogen today and begin to evaluate, commercialize and deploy SDN and NFV. With over a million lines of code, Hydrogen is the first simultaneous release of OpenDaylight delivering three different editions to help a wide array of users get up and running as quickly as possible--Base Edition, Virtualization Edition and Service Provider Edition. Hydrogen Base Edition is for those who are exploring SDN and OpenFlow for proof-of-concepts or academic initiatives in physical or virtual environments. Hydrogen Virtualization Edition for data centers includes all the components of Base plus functionality for creating and managing Virtual Tenant Networks and virtual overlays, and includes applications for security and network management. Service Provider Edition is for providers and carriers who manage existing networks and want to plot a path to SDN and NFV. It includes Base plus protocol support commonly encountered in service provider networks, as well as security and network management applications. *Key features of each Hydrogen edition:* Base Edition - Controller: A modular, extensible, scalable and multi-protocol SDN controller based on OSGi. - OpenFlow Plugin: Integration of OpenFlow protocol library in controller Service Abstraction Layer (SAL). - OpenFlow Protocol Library: OpenFlow 1.3 protocol library implementation. - OVSDB: Open vSwitch Database configuration and management protocol support, e.g. for Open vSwitch and other OVSDB servers. - YANG Tools: Java-based NETCONF and YANG tooling for OpenDaylight projects. Virtualization Edition (includes Base Edition) - Affinity Metadata Service: APIs to express workload relationships and service levels. - Defense4All: DDoS detection and mitigation framework. - Open DOVE: Multi-tenant network virtualization based on overlays, including control plane and Open vSwitch-based data plane. - Virtual Tenant Network: Multi-tenant network virtualization application using OpenFlow. Service Provider Edition (includes Base Edition) - Affinity Metadata Service: APIs to express workload relationships and service levels. - BGP-LS/PCEP: Support for traffic engineering with BGP-LS (BGP protocol library and topology model) and PCEP (path programming model). - Defense4All: DDoS detection and mitigation framework. - LISP Flow Mapping: Locator/identifier Separation Protocol plugin, LISP mapping service (can be used to implement virtual networks). - SNMP4SDN: SNMP protocol support and APIs to manage commodity Ethernet switches. “We are seeing new OpenDaylight implementations and solutions coming to the forefront every day,” said Neela Jacques, executive director, OpenDaylight. “All signs point to 2014 being a key year for the project as we continue to grow the community, build the architecture and engage with organizations and end users who want to accelerate the path to SDN and NFV.” OpenDaylight <http://www.lightreading.com/complink_redirect.asp?vl_id=13600> -- /doka

Hi all. Не то чтобы вопрос - но насколько наказуемо-ненаказуемо заворачивание ICMP трафика через другие каналы? А то у меня давеча у одних клиентов пропал мир и выяснилась странная вещь - пинги на сервера ходят, а трафик не идет.

OpenDaylight Unveils Open-Source SDN Controller | Light Reading
by Vladimir Litovka 13 Feb '14

13 Feb '14

Можно пробовать! :-) http://www.lightreading.com/carrier-sdn/sdn-architectures/opendaylight-unve… Hydrogen's architecture was announced last fall. Today's release is functional code that acts as a service abstraction layer that can provide the northbound capabilities to a wide range of routers and switches, and comes in a basic edition and two more advanced editions, one targeting the datacenter and another specifically adapted for service providers. The basic edition of the platform incorporates an OpenFlow Plugin and an OpenFlow Protocol Library, as well as Open vSwitch Database (OVSDB) support and YANG tools that enable NETCONF for automatic network configuration. The service provider edition adds support for protocols such as BGP-LS, LISP, and SNMP, all used in service provider networks, along with APIs for controlling Ethernet switches and *Defense4All, a distributed denial of service attack detection and mitigation framework. *
